Foreword
The past two decades in Ghana have been marked by steady economic progress, which has transformed the country into a lower-middle-income economy, accompanied by a decline in poverty, increases in incomes for families, improvements in health, and expanded educational opportunities. As Ghana looks forward to a future of economic growth, it needs to regain growth from the 2016 slowdown, including improving competitiveness and economic diversification and raising labor productivity. A well-equipped workforce will be key to obtaining these goals. The Government of Ghana and its development partners such as the World Bank have long recognized the importance of investments in human capital. Insufficient skills in young people will be an obstacle to improving competitiveness in all sectors across the economy, be they informal or formal, in traditional sectors or in the modern areas such as information and telecommunications technologies. An agenda for improving skills in the workforce relies on being able to identify where the more practical and profitable investments in the current skills profile should be made. To that end, Skills Toward Employment and Productivity (STEP) is an innovative tool used across the world to assess the education, cognitive, work-related, and socioemotional skills stock in a population, as well as the impact of these traits on employment and earnings. Ghana is among the first two countries (along with Kenya) in Sub-Saharan Africa where this systematic assessment of skills has been carried out. The evidence collected through this assessment shows that the multidimensional nature of skills requires nurturing from early childhood education to school and university systems, as well as through school-based and on-the-job training. This broad concept of skills has a significant impact both on jobs and on earnings, and the relationship is also mutual: jobs attract and reward skills. The information from the Stepping Up Skills in Urban Ghana study provides detailed insights for policy makers. These insights cover areas including investments in early childhood education, the role of improvements in the quality of education, and the creation of incentives for economic actors to invest in on-the-job training to improve Ghana’s competitiveness and the well-being of its citizens.

Overview
Introduction Ghana stands at the cusp of extraordinary opportunity. Since the country’s return to democratic rule and the advent of the Fourth Republic, per capita gross domestic product (GDP, current US$, PPP [purchasing power parity]) has increased almost fourfold, from US$375 in 1993 to US$1,442 in 2014. In 2011, Ghana was the only African economy to demonstrate double-digit economic growth, surpassing 14 percent that year. In the aftermath of the Chinese economic slowdown and the slump in global commodities markets, Ghana’s growth tempered to 4 percent in 2014 but is expected to recover above 8 percent in the medium term as the country begins exploiting significant oil and gas resources. Throughout the period of the Fourth Republic, fertility rates have remained relatively high, falling from 5.3 births per female in 1993 to 4.2 in 2014. Concurrently, the proportion of children under the age of 15 in the total population declined only marginally from 43 percent in 1993 to 39 percent in 2014. As a consequence, Ghana’s labor force has grown rapidly, from approximately 6.5 million in 1993 to 11.3 million in 2014, and is expected to continue to grow in the coming decades. Population growth has also contributed to an erosion of the effects of buoyant economic growth on poverty reduction. Although the country has made progress in reducing poverty—with the proportion of the population living below the government’s poverty line falling from 32 percent in 2005 to 24 percent in 2012—stubborn disparities persist with regard to access to economic, social, and political opportunities. Inequity is particularly evident in the differences between the populations of the poorer northern Savannah regions and the rest of the country. In the three northernmost administrative regions of the country, more than half, or

Overview
58 percent, of the population falls below the poverty line, compared to 19 percent in the seven administrative districts of the south of the country. The spatial distribution of poverty and economic opportunity, in turn, has led to significant migration from north to south, and a swelling of the ranks of the urban labor force. Nevertheless, a significant economic dividend is implicit in Ghana’s increasingly abundant urban labor force. If current and future generations of workers can be empowered to realize their potential in a vibrant and increasingly competitive economy, the prospect of sustained poverty reduction, further economic development, and the reaping of benefits associated with a demographic transition could profoundly reshape Ghana’s society and economy for future generations. Equipping current and future generations of workers with the skills they need to improve their livelihoods and to drive increases in national productivity and competitiveness requires that these workers have skills appropriately aligned with the needs of a growing economy. Some skills are innate, arbitrarily assigned through the accident of birth. Other skills are acquired through education, work, and life experience. The primary means through which a government can develop the skills of its labor force is through policies and strategies implemented through the education system. Jobs form the foundation of economic development, rising living standards, increases in productivity, and improved social cohesion. Equipping people with appropriate skills to access meaningful work constitutes the means for achieving these objectives. This report, premised on the Skills Toward Employment and Productivity (STEP) framework, considers education the instrument for learning and acquiring skills and the key for accessing employment. Although the Ghanaian government has made significant progress in expanding access to basic education, many challenges persist in the education sector. These include the low quality of learning in both basic and post-basic education, inequity of access, and the limited capacity of the education system to equip beneficiaries with skills aligned with increasing competitiveness and productivity in the economy. If education and training institutions are unable to provide the skills demanded by the market, economic inefficiencies could be compounded. Skills development strategies can be effective only if they are appropriately calibrated to the needs of the economy and only if they take into account the current skills endowment of the existing labor force. The most effective skills development strategies are informed by evidence, and effective implementation requires the ongoing collection of data to gauge shifting demand for skills and the changing character of the labor force and economy at large. To date, evidence regarding the stock of existing skills in Ghana’s labor force is relatively underdeveloped. The precise measurement of the prevalence of different categories of skills within the population is required for the effective design of policy interventions that target improved training to reduce skill gaps

Overview
aligned with the needs of specific sectors, improvement in productivity, and increased employability of workers. With the data it gathers, the first STEP household survey aims, in part, to address this deficiency through a rigorous analysis of the skills endowment of urban Ghanaian adults. The STEP survey was carried out between September 2011 and December 2013 in Ghana, as part of the first wave of surveys initiated under the STEP Skills Measurement Program. The Ghanaian sample consists of about 3,000 individuals between 15 and 64 years of age, living in urban areas across 71 districts. In addition to standardized information captured at the household level, the STEP survey collects information regarding the level of skill, level of education completed, and work history. On skills, the STEP survey includes information about (i) self-reported cognitive skills (that is, a subjective assessment of an individual’s use of foundation skills—reading, writing, and numeracy— at work and in daily life); (ii) assessed cognitive skills (that is, an objective assessment of reading literacy based on the International Adult Literacy Survey); (iii) socioemotional skills (that is, personality traits, behavior, and risk and time preferences); and (iv) job-specific skills (that is, an indirect assessment of skills used at work). The STEP framework is structured according to five iterative steps and associated objectives: (i) getting children off to the right start; (ii) ensuring that all students learn; (iii) building job-relevant skills; (iv) encouraging entrepreneurship and innovation; and (v) facilitating labor mobility and job matching. Ultimately, if these five steps are achieved, Ghana will significantly advance the likelihood of realizing the potential of its labor force, with considerable positive implications for the livelihoods of its people, poverty reduction, improved productivity, economic development, and the betterment of society at large.
Objectives This report is intended to complement and support the work of the Government of Ghana as it seeks to accelerate progress toward the achievement of the education-related Millennium Development Goals (MDGs) and the work of the Ministry of Education (MOE) and the Ghana Education Service (GES) in advancing the reforms envisaged by the Education Strategic Plan (ESP) for 2010–20. This report is divided into eight chapters: • Chapter 1 of the report describes Ghana’s economic, social, and demographic trends and the current challenges faced by the education system. Chapter 2 outlines the report’s framework for enquiry and a detailed description of the STEP framework. Chapter 3 provides an overview of the STEP survey’s sampling methodology, a description of methodologies used to measure each subset of skills, and limitations to the analysis.

Overview
• Drawing on data collected through the STEP survey, chapter 4 describes the education profile of the urban adult population; explores trends in preschool, primary, secondary, and tertiary completion rates, disaggregated by age group, gender, and region; explores the effect of socioeconomic and demographic factors on educational attainment, dropout rates, and age of entry into the education system; and looks at the relationship between education attainment and inequality. • Chapter 5 analyzes labor force participation, employment status, and underemployment; the correlation between labor market status and skills and education; and regional disparities in education and labor market opportunity. • Chapter 6 focuses on the use of cognitive skills (both self-reported and assessed), socioemotional skills, and technical skills. The authors analyze the mismatch between self-reported and assessed cognitive skills and the mismatch between respondents who report high levels of education attainment but who performed poorly when these skills were tested and vice versa. This section of the report aims to answer the following research questions: How do socioemotional skills relate to cognitive skills? Does inequality with regard to years of schooling reflect inequality in cognitive skills? What are the characteristics of respondents who under- or over-report cognitive ability? Do incremental increases in educational achievement result in more developed skill sets? • Chapter 7 looks at the association between education and skills and labor market opportunity. It discusses the extent to which it is worthwhile for individuals to invest in (or for others to subsidize) education and/or skills development and to what extent these investments inform the development of skills demanded by the economy. In so doing, this chapter aims to answer the following research questions: Does education lead to better job market opportunities? Do skilled (educated) workers demonstrate higher earnings? Does education inculcate job-relevant skills? Which skills matter the most for employability? How much of the wage premium accruing to educated people is explained by skills? Is training relevant in producing good skills? • Section 8 quantifies the magnitude of unused skills and underexploited potential within the labor force, examines the proportion of the employed population who do not use their skills at work, and weighs evidence of skills and education mismatching in the labor market.
Key Findings The Educational Profile of Ghana’s Adult Urban Population Ghana has made significant progress in expanding access to basic education, having achieved near universal access to primary education. However, challenges persist with regard to improving the quality of basic education to enhance learning outcomes and to expanding access to post-basic levels of education.

Overview
Moreover, a significant gender gap in educational achievement is evident for all levels of education in Ghana. The expansion of early childhood education (ECE) in Ghana’s urban areas has dramatically improved, and participation in ECE is positively correlated with household socioeconomic status and the intensity with which workers use basic skills. Only 30 percent of Ghanaians between ages 45 and 64 attended an ECE program compared to 87 percent of the youngest generation surveyed. Seventy-seven percent of adults living in households in the upper socioeconomic brackets had participated in an ECE program, compared to 49 percent of adults in the poorest households. Adults with ECE are more likely to read and write regularly and do so with greater intensity. Approximately two-thirds of students who complete primary school do so without demonstrating proficiency in core subject areas. In terms of the quality of senior high school (SHS) programs, a large disparity in further educational attainment is evident between students attending the highest-performing schools and the rest of the sector. The highest-performing 10 percent of high schools account for 90 percent of students entering university. There are significant regional, gender-based, and income-based disparities in access to and the returns accruing to post-basic education. Pass rates for the Basic Education Certificate Examination (BECE) vary greatly by region, with the poorest performance evident in the administrative regions of the north. The magnitude of difference in BECE pass rates for the north and south are upwards of 60 percent. Access to tertiary education has not changed substantially over time. Over three generations, the percentage of people with a tertiary qualification increased by only two percentage points, from 11 percent for adults ages 45 to 64 to 13 percent for respondents in the generation ages 25 to 34. A child’s age on entry to the school system is correlated with educational achievement. Officially, children should commence formal schooling at the age of six; however, in practice many children enter school later, with negative implications for further education. Approximately 51 percent of those with incomplete primary education enrolled in primary school at eight years of age, whereas 89 percent of those with postsecondary education enrolled at the official age of entry. Approximately one out of four members of the adult labor force dropped out of school prior to completing the highest grade of the level of education they had enrolled in, with the highest rates of dropout evident in the primary and junior high school (JHS) cycles of education. The most commonly cited reason for dropping out of school before the age of 16 is a lack of money for out-of-pocket expenses, regardless of the child’s socioeconomic status.
Labor Force Participation and Employment Status Characteristics The overall urban labor force participation rate in Ghana is 67 percent: 62 percent of respondents ages 15 to 64 years reported being employed, 5 percent reported being unemployed but looking for work, 23 percent were deemed Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

Overview
economically inactive (22 percent in education, 1 percent had retired), and 10 percent fell into the category “Not in Education, Employment, or Training” (NEET). A significant majority of the employed labor force works in the informal sector, primarily in self-employed work (66 percent) or as informal wage workers (20 percent). Only 15 percent of the employed population is engaged in salaried employment in the formal sector. However, these trends are changing, with younger generations less likely to be self-employed and more likely to hold salaried employment in formal or informal firms. Although female workers are as likely to be employed as their male counterparts, a significant gender gap exists in the quality of employment enjoyed by male and female workers. Across all age groups, female workers are more likely than male workers to be self-employed. Approximately half of male workers are self-employed, with the remaining share split almost evenly between formal and informal wage employment. By contrast, 79 percent of female workers are self-employed, and only 7 percent are retained as employees in the formal sector. A worker’s level of education is strongly associated with employment status. Approximately 37 percent of workers holding a tertiary qualification work in the informal sector (20 percent as self-employed and 17 percent as informal employees), compared to 99 percent of workers with no formal education (86 percent as self-employed and 13 percent as informal employees). A key determinant of a worker’s likelihood of accessing a job in the formal wage sector is education. Approximately 44 percent of workers in the formal sector have a tertiary education, 32 percent graduated from SHS, and 24 percent report JHS education or less. The level of educational attainment is also strongly associated with employment in higher-skilled occupations. The majority of the employed population works in low-skilled occupations in the informal sector, and just 13 percent of the working population is employed in high-skilled occupations, concentrated in the formal sector. SHS and tertiary graduates are more likely to be employed in mid- or high-skilled occupations than are workers with lower levels of educational attainment. Approximately 29 percent of SHS graduates are employed in the high-value-added services sector, compared to just 3 and 8 percent of workers in this sector having terminated their education following the primary and JHS cycles, respectively.
The Skills Profile of Ghana’s Adult Urban Population As mentioned previously, the STEP survey collects information about cognitive skills by asking people about their use of numeracy, reading, and writing skills and through an objective assessment of their reading proficiency. According to self-reporting by those surveyed, working-age Ghanaians use their numeracy skills on a regular basis, regardless of their level of education. At the same time, the use of reading and writing skills is significantly

Overview
lower and strongly correlates with the level of education and with employment status. The intensity of the use of reading skills is higher among SHS graduates and highest for respondents with a tertiary qualification. All respondents who received tertiary education report using their reading and writing skills on a regular basis, and approximately 64 and 60 percent of the population with primary education report the regular use of reading and writing skills, respectively. Nevertheless, even among those who completed tertiary education, almost half write only with low intensity. Similarly, 84 percent of formal employees reported using their reading and writing skills on a daily basis, compared with approximately 41 percent of informal wageworkers and 21 percent of self-employed workers. Overall, the use of reading and writing skills has intensified over time, with the youngest cohort surveyed reporting regular use of their writing (89 percent of respondents) and reading (90 percent) skills, compared to the oldest age cohort of workers who reported a lower regular use of reading (41 percent of respondents) and writing (41 percent). The results of the reading proficiency tests mirror the respondents’ self-reported levels of skill use. Educational attainment was highly predictive of relative success on the Core Literacy Test component of the survey. Ninety-three percent of those who failed the test reported educational attainment of JHS or less (42 percent report no formal education, and 33 percent attended JHS), whereas about 57 percent of those who passed the test have at least an SHS education and approximately 21 percent report having tertiary education. Nevertheless, average performance across all three measures of reading is low. Respondents who reported using their reading and writing skills more frequently performed better in sentence processing and passage comprehension tests than those who did not. However, poor performance on the print vocabulary subcomponent of the reading assessment was relatively uniform across all subgroups. Respondents with higher reported levels of educational attainment performed better on all aspects of the reading component. Younger respondents were more likely to perform better in sentence and passage comprehension tests than older respondents. Respondents with lower socioeconomic status, and for whom English was not their main language at home or at work, were less likely to pass the Core Literacy Test. Of those who passed the test, 73 percent reported using English as their primary workplace language, compared with 17 percent of those who failed the test. However, in light of the fact that the reading test was administered in English, it is not surprising that a higher percentage of those who passed the test report speaking English as their primary language at home and work than those who failed. Of the respondents who were employed, 81 percent of those who failed the reading test were self-employed and only 3 percent were formal wageworkers. By contrast, 38 percent of those who passed the reading assessment were self-employed and 34 percent were formal wageworkers, with one-third retained in high-skilled occupations. Respondents who passed the reading

Overview
assessment earned on average 274 GHS (approximately US$80) per month more than those who failed the test. Average performance on the Literacy Exercise Booklets section of the test, which allows for an in-depth analysis of reading ability, was very poor. Sixty-one percent of the subsample to whom the Literacy Exercise Booklets were administered scored on the lowest rung of proficiency. Respondents who attained higher scores were more likely to be younger, to have reported higher levels of educational attainment (SHS or tertiary), to work in the formal sector, to have reported the use of English as their primary home or workplace language, and to have reported using their reading and writing skills more intensively. Finally, it is worth mentioning that the data show a substantial mismatch between self-reported use of skills and tested literacy: of the sample as a whole, approximately 69 percent of adults reported reading regularly, but only 42 percent passed the Core Literacy Test component of the literacy assessment. However, the poor results in the Core test may reflect poor English literacy rather than present a true measurement of general reading skills. Those who reported being able to read but who then failed the Core test are more likely to be women, more likely to work in low-skilled occupations and to be less educated, and less likely to work in the high-value-added sector. Respondents who reported being able to read but then failed the Core test also earn approximately 41 percent less than those who reported being able to read and who passed the Core test. The analysis suggests that socioemotional skills are closely associated with educational attainment and labor market outcomes. Individuals with higher self-reported scores relative to the “Big Five” personality traits (stability, agreeableness, extraversion, conscientiousness, and openness) also had higher educational attainment. Similarly, individuals scoring higher on the Big Five personality traits, and who demonstrated lower levels of hostile bias, are less likely to be self-employed. The association between socioemotional skills and labor market outcomes is reversed nevertheless when controlling for education. This finding confirms that education and socioemotional skills are (positively) correlated and also suggests that the development of socioemotional skills might be one of the channels through which education can contribute to better labor market outcomes.
Job-Specific Skills Employment in the formal sector requires that a worker be capable of regularly learning new skills at work, more frequently involves the supervision of others’ work, and more often requires workers to make presentations. Survey data demonstrate that work in the informal sector is less cognitively demanding, more repetitive, and more physically demanding. Self-employed workers reported greater autonomy at work and a greater incidence of repetitive tasks than did wage workers.

Overview
Further Education and Training Approximately 32 percent of the population surveyed had actively engaged in activities to further develop their skills in the year prior to taking the survey. More than one in four respondents surveyed by STEP reported participating in an apprenticeship, and less than 7 percent had participated in a training course of 30 hours or more. Apprenticeship-based training is more common among self-employed workers, whereas formal wageworkers are more likely to enroll in skills training courses. Approximately 26 percent of formal workers reported attending a work-related or personal skills training course in the year prior to the survey, compared to 3 and 6 percent of self-employed and informal wageworkers, respectively. On the other hand, approximately 38 percent of self-employed and 25 percent of wageworkers had participated in an apprenticeship in the 12 months prior to the survey.
Returns to Education and Skills The analysis demonstrates that an additional year of education is associated with an increase of 6–10 percent in monthly earnings. After controlling for socioeconomic characteristics, primary education is associated with no distinguishable earnings premium for people with no formal education or incomplete primary education. On the contrary, the wage premium accruing to SHS and tertiary graduates is 29–79 percent (SHS) and 112–172 percent (tertiary) higher than the average wage of workers with no formal education or incomplete primary education. The premium for workers with JHS over workers with no formal education or incomplete primary education is much lower (35–59 percent). Returns to education and skills vary by type of employment and with respect to the type of skill. An additional year of education increases the monthly earnings of informal wageworkers by 4–6 percent, compared to 7–10 percent for formal wageworkers. However, taking into account the individual’s skills (cognitive, socioemotional, and job-related skills), the earnings premium associated with any additional year of education decreases by 2 percent. The premium accruing to a female worker through an additional year of education is higher than that accruing to male workers (between 9 and 13 percent for female workers, compared to between 6 and 9 percent for men). For male workers, a pronounced premium associated with educational attainment becomes evident only at the tertiary level, whereas the data suggest that substantial payoffs accrue to female workers from JHS and above. Furthermore, with respect to skills, the pro-women gender gap is persistent at tertiary education (female workers with tertiary education make 164 percent more than those without compared to a 118 percent advantage for men). However, this apparent gender gap may be misleading because it does not take into account the fact that average labor market participation and educational attainments are lower for female workers.

Overview
Evidence of an Unrealized Potential in the Labor Force An apparent mismatch between skills and their use at work could reflect unexploited human capital in the labor force. Within the overall population of employed adults, the evidence suggests that there is a subset of individuals who use their cognitive and computer skills at home but not at work. Moreover, there is a disproportionately large number of young workers who report being able to use a computer but who are not required to do so at work. The evidence suggests that the greatest residue of unexploited potential is located in lowskilled occupations and low-value-added sectors. Approximately 34 percent of self-employed workers report reading at home but never using this skill at work. On the other hand, only 6 percent of formal sector workers report this skills mismatch.

Chapter 1
Country Context
Economic, Social, and Demographic Trends In the contemporary period, Ghana has achieved sustained economic growth and significant poverty reduction. The country has experienced 20 years of positive economic growth (in the range of 4–5 percent) and in 2011, with yearon-year growth of 14.4 percent, was one of only seven countries in the world, and the only country in Sub-Saharan Africa (SSA), to achieve double-digit economic growth (IMF 2012).1 Improved economic performance has been accompanied by significant poverty reduction, underpinned by rural development and increasing urbanization. In rural areas, small-scale agriculture has benefitted from improved agricultural productivity (notably in cocoa), rising incomes, and rising domestic demand. Concurrently, Ghana’s rapidly growing urban centers have led to a significant expansion of the service sector and a growing labor force, inclusive of migrants from rural areas who have been absorbed into better-paying jobs in both the formal and the informal sectors of the economy. Despite this impressive progress, deep inequity continues to characterize Ghanaian society and is reflected in significant disparities in access to economic, social, and political opportunities. This is especially evident when observing differences in access to opportunity between the populations of the poorer northern “Savannah regions” and the rest of the country. The bulk of Ghana’s poverty is concentrated in the three northernmost administrative regions of the country: the Upper East, Upper West, and Northern regions. These Savannah regions (home to approximately one quarter of the country’s population) are the locus of an average poverty rate of 58 percent, compared to 19 percent in the seven administrative districts in the south of the country. Between 1995 and 2005, the number of people living in poverty fell by 2.5 million in the south. Over the same period the number of people living in poverty in the north increased by 0.9 million, although the poverty rate for this area declined because of an absolute increase in the population.2

Country Context
Unemployment and underemployment in Ghana are structural in nature, which is not atypical in SSA. However, when demographic trends are taken into account, the structural nature of the challenges becomes more pronounced, with most economies on the continent being unable to generate sufficient rates of growth to create the jobs required to absorb the ever-increasing number of workers entering the labor force. The scale of the challenge is evident in the fact that formal private sector employment accounts for only a small proportion of available manpower. To sustain and accelerate economic growth and poverty reduction, Ghana’s education strategy is focused on building the skills profile of the youth demographic (IMF 2012). The urgent need to intervene in this regard is underlined by a national median age of approximately 20 years (UNDP 2011). Although the country’s youth demonstrate the highest levels of educational attainment relative to older generational cohorts, younger workers also depend most on salaried employment because of the inability of rural agriculture to sustain workers and their families and the contingent movement of migrants from the countryside to Ghana’s urban centers. From a developmental perspective, the most important demographic trend is the pace and character of migration from the northern regions of the country to the south (figure 1.1). Migrants to cities in search of jobs, education, skills, and business opportunities disproportionately include large family groups with children of school-going age and unemployed youth with poor educational attainment.

Country Context
Education and Skills Ghana has made significant progress in expanding access to basic education over the course of the past 15 years. Having achieved near universal access to primary education, the country now faces two new urgent challenges: (i) improving the quality of basic education to enhance learning outcomes and (ii) expanding access beyond basic levels of education. The majority of students receiving upper secondary education in Ghana are enrolled in three-year senior high schools (SHS), following the completion of 11 years of basic education (comprising preprimary school, primary school, and junior high school [JHS]) (see box 1.1 for more information on Ghana’s education system). The government intends to universalize access to upper secondary education by enabling students who are unable to afford fees to attend secondary school at no charge. Informal apprenticeships currently equip many more workers with skills than do formal public technical and vocational education and training (TVET) programs.3 Fewer than 10 percent of workers with technical and vocational skills acquired their skills through public TVET institutions. Moreover, there are approximately one and a half times as many trainees enrolled in private TVET institutions as in public institutions, and the number of students engaged in informal apprenticeships is 10 times that of students enrolled in the formal TVET sector.
Box 1.1 The Ghanaian Education System In theory, the age range for children and young people engaged in the Ghanaian education system spans from 3 to 21 years. The educational system in Ghana consists of the following cycles or levels of education: • Preschool, equivalent to U.S. kindergarten (ages 4–5) • Primary school (ages 6–11) • Junior high school (JHS), equivalent to U.S. middle school (ages 12–14) • Senior high school (SHS), equivalent to U.S. high school (ages 15–17) • Tertiary education/institution, equivalent to U.S. college/university (ages 18–21) A full cycle of basic education is optimally provided over the course of 11 years, comprising two years of kindergarten, six years of primary school, and three years of JHS. Ghanaian children enter class one (first grade) during the calendar year in which they reach their sixth birthdays. During the first three years, the medium of instruction is either English or a combination of English and local languages. JHS education comprises forms 1 through 3 (U.S. grades seven through nine). Admission to JHS is open to any student who has completed primary class six. There is no entrance exam, and JHS education is considered integral to the country’s nine-year cycle of basic education, to which all Ghanaian children are entitled. At the end of JHS form 3 (ninth grade), students sit box continues next page

Box 1.1 The Ghanaian Education System (continued)
for the Basic Education Certificate Examination (BECE) in nine or ten subjects. The BECE is administered and graded by the West African Examinations Council (WAEC). Admission to SHS is based exclusively on a student’s BECE results. After JHS, students may choose to go into different streams within the SHS system or to pursue further skills acquisition through an apprenticeship scheme with some support from the government. All SHS courses prepare students for university education, but most TVET students are likely to join the labor market once they graduate. SHS consists of forms 4 through 6 (equivalent to U.S. grades 10 through 12). The core SHS curriculum comprises six subjects—English, science, mathematics, social studies, physical education, and religious and moral education—which are studied throughout the three-year SHS cycle. Students undergo examinations only in the first four of these subjects. To complete a full course of SHS education, each student must choose—in addition to the core curriculum— one program (general arts, general science, agriculture, economics, business, or technical and vocational) and three or four elective subjects from within that chosen program. At the end of the three-year SHS cycle, all students are required to sit the West African Senior School Certificate Examinations (WASSCE). Usually, the student’s overall score is determined by aggregating the student’s grades in his or her elective subjects and then adding this score to the aggregate score of the student’s best “core” subjects, with scores in English and mathematics considered first. The Ministry of Education considers any SHS graduate with an aggregate score of 24 (a D average) or better to be a successful school-leaver, equivalent to a graduate of a U.S. high school. Entrance to universities is by examination following the completion of SHS. Students obtaining aggregate scores of 36 or above (six subjects) on the WASSCE can enter university. After completing SHS, students also have the option to pursue further education through a polytechnic.
Persistent Challenges in Education Despite Ghana’s steady economic growth and improved access to basic education, many challenges persistent in the education sector. Among other things, the primary challenges concern • The poor quality of learning outcomes, in both basic and post-basic education; • Inequity of access, especially in secondary education; and • The limited capacity of the education system to create relevant skills aligned with increasing competitiveness and productivity within the economy. The National Education Assessment carried out biannually since 2005 shows a persistent trend: approximately two-thirds of students who complete primary school do so without demonstrating proficiency in core subject areas. In terms of the quality of SHS programs, the annual WASSCE demonstrates a large disparity in further educational attainment between students attending the 100 highestperforming schools and the rest of the sector. The highest-performing 10 percent Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1
Country Context
of high schools account for 90 percent of students entering university. Approximately 65–70 percent of SHS graduates do not continue education at the tertiary level. Students exiting the SHS cycle with low WASSCE scores are unable to access tertiary education, with many of these graduates going on to enroll in some form of training or apprenticeship program. There are significant regional, gender-based, and income-based disparities in access to, and the relevance of, post-basic education. The 2010 Population and Housing Census and the 2013 Ghana Living Standards Survey (GLSS) demonstrate very low pass rates for the BECE in the Upper East (11 percent), Volta (17 percent), and Northern and Upper West (both 22 percent) administrative regions, compared to high pass rates in the Greater Accra (90 percent), Western (88 percent), Brong-Ahafo (86 percent), and Ashanti (81.5 percent) regions (GSS 2013, 2014). Survey data also demonstrate that the limited capacity of Ghana’s education and training systems inhibits their ability to produce human capital of sufficient quality to meet the needs of the labor market and to drive a more competitive and diversified economy. Many JHS and SHS graduates are unable to find jobs in the formal sector, or are unable to pursue further education and training because of poor performance in exit examinations, a lack of information, and/or the suboptimal supply of training providers. Consequently, many JHS and SHS graduates are limited to self-employment or finding employment in the informal sector. According to data from the most recent National Census (2010), approximately two-thirds of the adult population is self-employed, and the proportion of employment accounted for by the formal private sector has declined since 2000 (GSS 2013). Formal (public or private) employment accounts for only 17 percent of total employment and is disproportionately concentrated in urban areas, although a relatively large minority of public employees—primarily teachers—are present in rural areas. Skills development in Ghana encompasses the inculcation of foundational, or basic, skills (literacy, numeracy); transferable and soft skills; and technical and vocational skills. These skills are acquired over the course of a lifetime through formal education, training, and higher education; through on-the-job and professional training; and through the family, community, and media. The majority of young Ghanaians acquire technical and vocational skills through informal onthe-job apprenticeships (Darvas and Palmer 2014). Although the scale and scope of Ghana’s TVET systems are difficult to measure, clear opportunities exist for further skills development at the intersection of education, youth, and the needs of the labor market (Darvas and Palmer 2014). Enterprise surveys demonstrate mixed perceptions on the part of firms with respect to the quality of workers’ skills and the extent to which poor skills act as a constraint to improved economic performance (Darvas and Palmer 2014). However, in light of the demonstrable inadequacy of the supply of relevant and quality skills to the economy, a more deliberate analysis of enterprise survey data is required to more effectively understand the underlying causes of the apparent low demand for skills.

human capital and economic development are to be successful, it is imperative that skills development strategies are premised on a thorough understanding of the existing supply of and demand for skills, as well as of the use of skills in the economy, in order to more effectively match the supply of skills to demand (Campbell 2012; Darvas and Palmer 2014). Despite the central role skills play in shaping employment outcomes, there is very little information about the distribution of different types of skills in the Ghanaian labor force or of their contribution to labor market outcomes. Ultimately, the paucity of relevant information undermines the design of more effective skills development policies and programs (World Bank 2014). The Skills Toward Employment and Productivity (STEP) project—through its use of a framework enabling the analysis of Ghana’s labor market conditions based on internationally comparable skills data—will help to address this knowledge gap and assist in the development of policies aligned to the needs of the economy.

Chapter 2
Conceptual Framework: Why Is It Important to Focus on Skills?
Introduction It is generally recognized that there is a strong positive correlation between the educational and skills profile of the workforce and a country’s per capita gross domestic product (GDP)—which is intended here as a proxy of productivity. Thus, education and training are the foundations for a skilled workforce and would benefit not only individuals but also the economy as a whole. If the education and the training system are of low quality, however, workers will be ill-prepared for the labor market. This could lead to several types of mismatches. For example, the education level of an individual may not match his or her skills, or individuals may overrate their own skills, thus leading to a mismatch between self-reported skills and tested skills. In another type of mismatch, workers may lack the skills required for available jobs or lack access to high-quality training programs that would increase their skill level and enable them to apply for higher-productivity jobs. As a result, many employees are either under- or overqualified for their occupations. These mismatches lead to a loss of human capital and show that having post-basic or higher education does not automatically translate into getting a good job. In all of these cases of mismatch, investments in education may not pay off. Education policy makers and other education stakeholders in Ghana are paying more attention to learning outcomes by testing all students from early grades through basic and post-basic education. Various research and diagnostic work has highlighted the fact that the reading and mathematics proficiency of Ghana’s students continues to be below acceptable levels. This means that most of them are unable to reach important milestones in literacy, to access post-basic education, or to develop a foundation for lifelong learning. As a result, their employment prospects are limited. Policy makers have identified the low quality of inputs and the limited relevance of science and technology education as being

among the main causes of these limited prospects. Policy makers also highlight Ghana’s large disparities in learning outcomes and related inequalities in the delivery of education services.1 Furthermore, policy makers and researchers have also homed in on several persistent challenges on the demand side. Not only do services and educational performance vary greatly by students’ social and economic status and by geography, but demand for skills, job opportunities, productivity, and expectations also vary widely and are affected by similar disparities. Despite the central role played by skills in improving employment outcomes and increasing productivity and growth in Ghana, information about the supply and demand of skills is sparse. Assessments of supply have largely focused on the outputs of mostly school and tertiary-level education and training institutions, whereas assessments of demand rely only on the responses to a few questions in enterprise surveys and rate-of-return analyses based on the last three Ghana Living Standard Surveys (GLSS) carried out in 1995, 1999, and 2005.2 Recently, more systemic analyses, surveys, and impact evaluations have been initiated, and we hope their results will inform future policy making. The lack of data and information on the skills endowment has made it difficult to design skills development policies and programs in Ghana, as in many other Sub-Saharan African (SSA) countries. Precise measurement of the prevalence of different types of skills among the population is needed to inform the design of public policies to reduce skill gaps in specific sectors, to increase the employability of the population, to improve training, and to enhance productivity. The Skills Toward Employment and Productivity (STEP) framework considers education as the instrument that enables individuals to learn and acquire skills, and subsequently access employment (box 2.1). Jobs are the foundation of economic development, improved standards of living, improved productivity,
Box 2.1 Skills Toward Employment and Productivity (STEP) The STEP framework (see figure B2.1.1) is informed by the following five interlinked steps: • Step 1. Getting children off to the right start—by developing the technical, cognitive, and behavioral skills conducive to high productivity and flexibility in the work environment through early child development (ECD), emphasizing nutrition, stimulation, and basic cognitive skills. Research shows that the handicaps built early in life are difficult if not impossible to remedy later in life and that effective ECD programs can have a very high payoff. • Step 2. Ensuring that all students learn—by building stronger systems with clear learning standards, good teachers, adequate resources, and a proper regulatory environment. Lessons from research and ground experience indicate that key decisions about education systems involve how much autonomy to allow and to whom, accountability from whom and for what, and how to assess performance and results. box continues next page

• Step 3. Building job-relevant skills that employers demand—by developing the right incentive framework for both pre-employment and on-the-job training programs and institutions (including higher education). There is accumulating experience showing how public and private efforts can be combined to achieve more relevant and responsive training systems. • Step 4. Encouraging entrepreneurship and innovation—by creating an environment that encourages investments in knowledge and creativity. • Step 5. Matching the supply of skills with the demand—by moving toward more flexible, efficient, and secure labor markets. Avoiding rigid job protection regulations while strengthening income protection systems, complemented by efforts to provide information and intermediation services to workers and firms, is the final complementary step transforming skills into actual employment and productivity.

and social cohesion. As a consequence, equipping people with the right mix of skills is the means for achieving these objectives.
Which Skills Are Relevant? A worker’s skill set comprises different categories of skills, including cognitive skills, social and behavioral skills, and technical skills (see figure 2.1). These categories of skills relate to job skills relevant to specific occupations as well as to Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

They also include literacy, numeracy, and the ability to understand complex ideas, to apply lessons accrued through experience, and to analyze problems using logical thought processes. Social and behavioral skills relate to personality traits that are linked to labor market success, such as an individual’s relative openness to new experiences, conscientiousness, extraversion, agreeability, and emotional stability. Technical skills range from manual dexterity in the use of complex tools and instruments to occupation-specific knowledge and skills for use in professional and technical occupations such as engineering or medicine.
How Are Cognitive, Behavioral, and Technical Skills Formed? The process of skills formation should be considered as a continuum spanning an individual’s life, with critical stages for the development of both cognitive and socioemotional skills. Four features of skills formation are particularly relevant to the development of a skills strategy: 1. Foundational cognitive and behavioral skills are formed early in an individual’s life and serve as a platform upon which other skills are developed. Children who fall behind early face significant disadvantages in catching up with their peers. Non-cognitive skills appear to be more malleable throughout life, but early interventions appear to have significant positive effects for their further development in the longer term. 2. Aggregate skills formation and development benefit from previous investments in skills development and are cumulative over an individual’s life. For example, a child who has learned to read fluently by second grade will be able Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1
Conceptual Framework: Why Is It Important to Focus on Skills?
to absorb more in third grade than a child of equivalent age who cannot read at the commencement of grade three. This implies that early investments in skills development are likely to have a greater longer-term impact on aggregate skills formation because it is easier and less costly to develop these skills when children are young and most receptive to learning. 3. Social and behavioral skills are particularly valuable early in a child’s life because they support, and benefit from, the development of cognitive skills. For example, children who are open to new experiences are more likely to be imaginative and creative and to apply themselves at school. 4. The acquisition of technical and job-specific skills is facilitated by strong cognitive and behavioral skills acquired earlier in the education system. These skills are often acquired last, through technical and vocational education and training (TVET), higher education, and on-the-job learning. The skills learned in formal education help workers to continuously update their technical skills during their working lives.
Understanding the Focus on Adults and Urban Areas Early investments are smart and cost-effective and prepare future generations of workers for the labor market. However, skills development strategies should also focus on maximizing the potential of current generations of workers. In recent decades Ghana has experienced large-scale migration from more rural and comparatively impoverished areas to Ghana’s more prosperous and urban areas. Migrants are disproportionately young adults who are motivated by educational opportunities and jobs in cities. Urbanization represents both a challenge and an opportunity for development because it has been associated with rising per capita income in Europe, Latin America, and, more recently, Asia. However, Africa has been an exception in this regard, because of the fact that in many African countries, including Ghana, industrialization has generally not accompanied urbanization. The majority of migrants to Ghana’s urban areas find employment in the comparatively poorly productive informal sector. However, even informal employment is, in many instances, much more than migrants could aspire to in their home regions. Equipping migrants with skills aligned with the needs of the urban labor market would give them a further opportunity for self-improvement. Accurately measuring the skills of the adult population is critical for informing policies aimed at increasing the productivity of those already in the labor force. Understanding the demographic structure and the socioeconomic status of the adult population in Ghana, as well as the associations between levels of education and an individual’s skills endowment, will help to inform the development of effective nonformal education and skills development programs aligned with the specific contextual characteristics of Ghanaian society and the labor force. It is for this reason that the STEP Skills Measurement Survey (discussed in the next chapter) is premised on gathering information about the skills endowment of the adult urban population.

Skills Toward Employment and Productivity Data
Introduction The Skills Toward Employment and Productivity (STEP) survey provides a unique opportunity to collect information on the use of skills and skills proficiency in Ghana. The objective of the study is to yield a clearer understanding of the complex relationship between skills, employment, and productivity. This chapter discusses the characteristics of the sample used in the Ghana STEP survey, the data arising from the survey, and the definitions of skill and other variables used in this analysis.
Data and Sample Characteristics This household survey was carried out in Ghana as part of the first wave of surveys under the STEP Skills Measurement Program between September 2011 and December 2013. The Ghanaian sample was gathered through a two-stage random sampling of households and individuals. It consists of 2,987 individuals between 15 and 64 years of age. Table A.1 in appendix A provides a complete description of the sample in terms of demographic characteristics, education, language, labor and employment status, economic sector and occupation, and geographic region. It is important to note that the weighted sample represents only the urban population. Therefore, the findings of this report cannot be extended to the national level because the urban population is likely to differ from the rural population along many dimensions. For example, workers in the urban areas are likely to have higher education levels and to be relatively more concentrated in the services sector than workers in the rural areas. Along with the standard information captured at the household level, the STEP survey collects extensive information on the skills level, education, and work history of one individual between ages 15 and 64 randomly selected from

each sampled household (figure 3.1). The survey includes three innovative modules on skills: (i) a specially designed assessment of reading literacy and competence to access, identify, integrate, interpret, and evaluate information, scored on the same scale as the test in the Program for the International Assessment of Adult Competencies (PIAAC) of the Organisation for Economic Co-operation and Development (OECD); (ii) a battery of questions capturing self-reported information on personality traits and behaviors; and (iii) a series of questions on job-specific skills that the respondent possesses or uses in his or her jobs. The skills of the entire sampled population are captured, irrespective of their labor force status (employed, unemployed, or inactive) or sector of employment.
Types of Skills Measured The STEP survey evaluates three categories of skill: (i) cognitive (self-reported and direct assessment); (ii) socioemotional skills; and (iii) job-specific skills. Table 3.1 and appendix B summarize the dimensions of skills captured in each category, and the corresponding survey questions used to create the relevant variables for analysis.

Cognitive Skills The STEP survey measures cognitive skills in two ways: First, respondents are asked to report whether and with what intensity they use their reading, writing, and numeracy skills in daily life and at work (if they work). These measures are likely to capture a combination of an individual’s actual ability to conduct tasks involving these skills and their motivation or opportunity to do so. Second, the survey makes use of an objective literacy assessment to directly measure cognitive skills. The self-reported questions capturing the use of reading and writing skills may substantively differ from an individual’s actual ability to read or write. The STEP literacy test has been aligned with a series of large-scale international surveys, such as the International Adult Literacy Survey (IALS), the Adult Literacy and Life Skills Survey (ALL), and the PIAAC. The assessment consists of three parts: Reading Components, the Core Literacy Test, and the Literacy Exercise Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

Booklets, as shown in figure 3.2. The Reading Components focus on foundational reading skills, including a respondent’s ability to assess word meaning, process sentences, and comprehend passages. The Core Literacy Test consists of eight literacy questions, which function as a screen to sort the least literate respondents from those with the highest literacy skills. Only respondents who were capable of answering two or more questions of the Core Literacy Test correctly are asked to complete the Literacy Exercise Booklets. The Booklets are broken down into four parts with a total of 18 questions, which allow for a more granular evaluation of reading skills among the relatively more literate respondents. All tests are conducted in English (see box 6.1 for further discussion). Cumulatively, the data gathered by the STEP survey consist of: (i) the Reading Components score(s),1 (ii) pass/fail information for the Core Literacy Test, and (iii) the score obtained in the Exercise Booklets grouped into five levels of competency (table 3.2), inclusive of descriptions of basic literacy skills from 1, the lowest level, to 5, the most advanced level.
Socioemotional Skills Socioemotional skills refer to skills and traits that are not directly related to intelligence, such as social, emotional, personality, behavioral, and attitudinal skills. The measures used to capture behavioral attributes are less established

Table 3.2 Levels of Reading Proficiency Literacy Below Level 1 (0–175) The tasks at this level require the respondent to read brief texts on familiar topics in order to locate a single piece of specific information. Only a basic knowledge of vocabulary is required to complete these tasks, and the reader is not required to understand the structure of sentences or paragraphs or make use of other text features. There is seldom any competing information in the text, and the requested information is identical in form to information in the question or directive. Although the texts can be continuous, the information can be located as if the text were noncontinuous. Tasks below level 1 do not make use of any features specific to digital texts. Literacy Level 1 (176–225) Respondents are required to read relatively short digital or continuous print, noncontinuous print, or mixed texts to locate a single piece of information that is identical to, or synonymous with, the information given in the question or directive. Some tasks may require the respondent to enter personal information into a document, in the case of some noncontinuous texts. Little, if any, competing information is present. Some tasks may require simple processing of more than one piece of information. Tasks at level 1 require knowledge and skill in recognizing basic vocabulary, evaluating the meaning of sentences, and reading paragraph text. Literacy Level 2 (226–275) At this level the relative complexity of the text increases. Texts may be digital or printed, and may comprise continuous, noncontinuous, or mixed types of text. Competing pieces of information may be present. The completion of level 2 tasks requires respondents to match the text to information and may require the ability to paraphrase or make low-level inferences. Tasks require the respondent to • Cycle through or integrate two or more pieces of information against given criteria; • Compare, contrast, and/or reason about information requested in the question; or • Navigate within digital texts to access and identify information from various parts of a document. Literacy Level 3 (276–325) Texts at this level are comparatively dense and lengthy, and include continuous, noncontinuous, mixed, and/or multiple pages. Respondents must demonstrate an understanding of textual and rhetorical structures to successfully complete tasks, especially in the navigation of complex digital texts. Tasks require the respondent to identify, interpret, or evaluate one or more pieces of information, and often require varying levels of inference. Many tasks require the respondent to construct meaning across larger chunks of text, or perform multistep operations in order to identify and formulate responses. Tasks may also require that the respondent disregard irrelevant or inappropriate text to answer the question accurately. Competing information is present, but it is not more prominent than correct information. Literacy Level 4 (326–375) Tasks at this level require respondents to perform multiple-step operations to integrate, interpret, and/or synthesize information from complex or lengthy continuous, noncontinuous, mixed, or multiple-page texts. Complex inferences and the application of background knowledge may be needed to perform successfully. Many tasks require the identification and understanding of one or more specific, noncentral ideas in the text to interpret or evaluate subtle evidentiary claims or persuasive discursive relationships. Conditional information is frequently present in tasks at this level and must be taken into consideration by the respondent. Competing information is present and may be as prominent as correct information. Literacy Level 5 (376–500) At this level, tasks may require the respondent to search for and integrate information across multiple, dense texts; construct syntheses of similar and contrasting ideas or points of view; and/or evaluate evidence-based arguments. Application and evaluation of logical and conceptual models of thinking may be required to accomplish tasks. Evaluating the reliability of evidentiary sources and selecting key information is frequently a requirement to successfully complete tasks. Level 5 tasks require respondents to be aware of subtle, rhetorical cues, to make high-level inferences, and/or to use specialized background knowledge. Source: Adapted from Valerio et al. 2014.

than those used to measure cognitive skills, in part because of the absence of a consensus on the structure and evolution of personality. STEP builds on the “Big Five” personality traits (openness, conscientiousness, extraversion, agreeableness, and stability), a widely accepted taxonomy for capturing personality traits. This taxonomy has been found to be replicable across cultures and can be used to capture the evolution of a personality over an individual’s lifetime (John and Srivastava 1999). Measures of grit and hostility bias were also included. The survey of socioemotional skills includes a module aimed at assessing respondents’ time and risk preferences.
Job-Specific Skills Job-specific skills are task related and build on a combination of cognitive and noncognitive skills. The STEP survey asks individuals about specific tasks they perform and the skills that they use in their current job. Questions on job-specific skills are intended to capture an individual’s technical skills, reflecting his or her acquired knowledge in particular areas. Because technical skills are often specific to a certain discipline, they are difficult to capture using a survey instrument aimed at the general population. As a consequence, the STEP survey focuses on a range of skills relevant to performance in multiple jobs.
Methodology This report uses a combination of descriptive statistics, simple probability models (to estimate what determines the probability of acquiring education and skills and of finding employment), and the Mincer equation (to estimate the returns to education and skills). The descriptive analysis includes simple distributions of the use and intensity of use of skills across genders, age cohorts, different socioeconomic statuses, and regions. The estimation is done using the sample weights, and the results are representative for the urban population of Ghana. The returns to education are estimated using a Mincerian wage regression. The total log monthly earnings of the main and second occupation are estimated as a function of education and a number of control variables (as detailed in appendix C). The sample is restricted to those individuals with monthly earnings different from zero, and models are estimated using ordinary least squares (OLS) with robust standard errors. For all skills, dummies of nonresponse (missing variables) have been included in the regression. These models describe associations between earnings and education or skills but do not claim any causal relation. If a person with a college degree earns more than a person with lower education it does not necessarily mean that the college education is the cause of the difference in pay. Rather, the person who went to college might have some characteristics that make him or her more productive in the labor market, thus resulting in higher earnings. It is possible, for example, that high-ability people self-select themselves into college. Thus, higher productivity might be the result of this selection rather than the consequence of the education level achieved. Therefore, it is uncertain whether the education premium reflects Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1
Skills Toward Employment and Productivity Data
the returns to education or a higher market value of unobserved skills. In an attempt to alleviate this selection problem, the regression model included a broad set of controls. Nevertheless, there are many other observable and unobservable factors that might affect both the probability of being employed and of working in specific sectors and occupations and the returns to education.
Note 1. The scores for Reading Components will depend on whether there are sufficient data to report three subscales or just a single reading components score.

Education Issues in Ghana
Foundational Skills: Early Childhood Education Early childhood is a critical stage for long-lasting skills development. Investment in children between the time of birth and the beginning of primary education is a major determinant of their future school performance and labor market success. Various studies find a strong association between cognitive and socioemotional skills gained at a young age and school achievement, graduation rates, and employment outcomes. Provision of early childhood education (ECE) in Ghana has dramatically increased since 2000. Only 30 percent of Ghanaians between the ages of 45 and 64 attended an ECE program (kindergarten, crèche, day care, and/or nursery school) against 87 percent of the youngest generation ages 15–19 years old. Interestingly, there are no significant differences in ECE participation between males and females. Participation in preschool is positively correlated with household socioeconomic status. Seventy-seven percent of adults living in households in the upper socioeconomic brackets participated in an ECE program as compared to 49 percent of individuals from the poorest households (figure 4.1). This is consistent across all age cohorts. Adults who received ECE are more likely to read and write regularly. Adults who did not attend preschool programs report lower levels of reading and writing regularly (47 and 45 percent, respectively) compared with 82 and 77 percent of those who benefitted from ECE (figure 4.2). Almost all of the population reported using their numeracy skills on a daily basis. Figure 4.3 demonstrates that those who participated in ECE also use their reading, writing, and numeracy with more intensity. Only 27 percent of the adult population of Ghana uses a computer. A third of those who attended ECE programs use one, whereas only one in every ten adults who did not attend ECE uses one. Over time, access to primary and secondary education has substantially increased. In fact, most of the population has completed at least primary education (80 percent) and junior high school (JHS) (69 percent) (figure 4.4).

In general, younger generations have more years of schooling than their elders. Whereas adults in the 45–64 age cohort have an average of 7.4 years of education, adults ages 20–24 have 2.6 more years of schooling. About 14 percent of adults ages 20–24 report not having completed primary education, but the equivalent figure was 31 percent among the oldest generation (ages 45–65) (figure 4.5). Also the proportion of adults who have completed senior high school (SHS) has increased substantially over time. About 37 percent of adults ages 20–24 have completed SHS against only 13 percent of the oldest generation. Tertiary education is also increasing but at a slower rate. In three generations the percentage of people with a tertiary education increased by only two percentage points, from 11 percent for the 45–64 age group to 13 percent among the 25–34 age group (figure 4.5). About 29 percent of the 20–24 age cohort is still attending tertiary education, and 5 percent have already graduated (see box 4.1 for a discussion of educational attainment and education levels).
Regional Disparities in Access to Primary Education Although primary education attainment among younger adults has increased in all regions, the increase, as measured in the Skills Toward Employment and Productivity (STEP) survey, was more significant in the Northern, Brong-Ahafo, and Volta regions. Nevertheless, it is worth remembering that, although similar trends are likely to have occurred in the Upper West and Upper East, the STEP Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1
Education Issues in Ghana
Box 4.1 Definitions of Education Variables The education variables include five subgroups of respondents: (i) those with no formal education or incomplete primary (henceforward called the “No education” or “None” subgroup); (ii) those with complete primary education; (iii) those who completed junior high school (JHS); (iv) those who completed senior high school (SHS); and (v) those who completed tertiary education. We define two variables for education: educational attainment and educational level. Educational attainment identifies the percentage of the population that has completed a specific education level whereas education level identifies the maximum level of education achieved. For example, someone whose education level is tertiary has attained primary, secondary, high school, and tertiary education. Thus, tertiary attainment is the ratio of those with tertiary-level education to all those who achieved (or are currently attending) a lower level of education. Notably, educational attainment is age independent. Indeed, at the denominator, it takes into account only those who, given their age, might have achieved the same level of education. Thus, for example, tertiary education attainment is the ratio of individuals at least 21 years of age having completed tertiary education to the same age-specific group with lower educational attainment. The age references for each educational level are defined as following: 11 years old and above for primary level, 14 years old and above for JHS, 17 years old and above for SHS, and 21 years old and above for tertiary level. Educational attainment is therefore useful for understanding the coverage of a specific education level within a population. For instance, if 80 percent of the population in a country has attained primary education, this includes those who have also achieved higher levels of education. In contrast, when analyzing educational level, the focus is on the highest level completed by the population. Educational level is useful for analyzing how the overall years of education completed by individuals might be correlated with their labor force participation, health, and life outcomes.
survey’s small sample of urban households made it impossible to measure them. In the Northern region the proportion of people who attained (or currently attend) primary education increased from 22 percent among adults ages 45–65 to 100 percent among the youngest population. Similarly, in Brong-Ahafo only 42 percent of the 45–64 cohort attained primary education compared to 96 percent of the youngest cohort. The Central region is the only region that is lagging behind, with only 83 percent of those 15–19 years old having attended primary education (figure 4.6).
Socioeconomic Disparities As might be expected, educational attainment increases with household wealth. More than 36 percent of individuals from the lowest quintile have not completed formal education compared with only about 19 percent of individuals from the highest income quintile (figure 4.7).

Nevertheless, Ghana is far from universal attainment in basic education, even among the urban population, and the education disparity is increasing. The richest segment of the population has been driving most of the improvement in education achievement—especially at the secondary level. Educational level has increased more quickly among the wealthiest, thus increasing the education gap between the poor and the wealthy (figure 4.8).

Constraints for Education: Late Entry, Completion Delay, and Dropouts Delaying school entry correlates to educational achievement. The average age for starting school for all Ghanaians is 7 years even though the official entry age is 6 years old. On average, those who completed a higher level of education began school around the official age of entry. About 51 percent of those who never complete primary education enroll in school at age 8, whereas 89 percent of those with a post-secondary education enrolled at the official entry age. Figure 4.9 shows the average age of school entry and completion for each level of education achieved compared with the official ages for entry and graduation. Although education attainment is increasing, delays in completion remain prevalent. Primary school should be completed by age 11, JHS by age 14, and SHS by age 17. However, those whose maximum level of education is primary graduate at an average age of 16.4. Considering their late entry, it takes them almost nine years to complete this level, four years more than expected (figure 4.9). For JHS and SHS, the difference between the actual and expected ages of graduation decreases, with the difference being about three years for both JHS and SHS. However, students are graduating from SHS at the age at which they should be finishing tertiary education instead. Tertiary education is the level with the highest delay in completion: although the expected age of completion is 21, the graduation age is on average almost six years later. Almost one out of four adults dropped out of school. The dropout rate is highest during primary education and JHS: among dropouts, 44 percent left school before completing primary education, 37 percent while attending JHS, 16 percent while attending SHS, and 4 percent during tertiary education. Among those starting primary education, 82 continue with a higher level of education; for 8 percent, primary education is their highest level of education, and 10 percent dropped out of primary education before completing it (figure 4.10, panel a).

Among those starting JHS, 10 percent dropped out before completing this level; 9 percent of SHS students dropped out before completing SHS. Most of the dropouts belonged to households with low socioeconomic status when they were 15 years old. Whereas the dropout rate for individuals from the richest households is about 26 percent, this rate increases to 38 percent among the poorest households (figure 4.10, panel b).

The lack of money for out-of-pocket expenses is the top reason for dropping out at age 15 for all households, regardless of their socioeconomic status. Among the poorest households, which suffered the highest dropout rate, 66 percent mentioned lack of money for fees, uniforms, or school materials as a reason for dropping out (figure 4.11). High opportunity costs were the second most frequently mentioned reason. These high opportunity costs stemmed from the fact that students with lower qualifications might (relatively) easily find self- employment in the informal sector.
The Gender Gap in Education The gender gap in education attendance is significant for all levels of education in Ghana (figure 4.12). For example, at 26 percent, the proportion of female students completing SHS education is significantly lower than the completion rate of male SHS students, at 47 percent. Moreover, in primary education, 74 percent of female students enrolling in primary education complete a full course of primary education, compared to 88 percent for their male counterparts. The gender gap in the primary completion rate is still significant. Females make up a larger proportion of adults with no formal education. About 13 percent of men and 26 percent of women have no or an incomplete primary education. Nevertheless, women’s educational attainment at both the primary and secondary level is increasing over time (figures 4.13 and 4.14).

41 percent of women have no formal education (compared with 18 percent of men), but this proportion is 23 percentage points lower among the youngest cohort. Similarly, only 8 percent of women ages 45–64 have SHS education against an SHS completion rate of 35 percent among the youngest. In sum, the STEP survey data show a clear trend of increases in education attainment across generations. Although driven mostly by deprived regions catching up with the rest of the country, these increases were also led by the highest-income groups. Despite improvements, inequality persists because lowerincome groups continue to have high opportunity costs.

Chapter 5
Labor Market Participation
Introduction Following the analysis of education attainment based on the Skills Toward Employment and Productivity (STEP) survey, we analyze the survey’s data on labor force participation and employment. The labor force participation rate in Ghana is 67 percent, with 62 percent reported to be working and only 5 percent to be unemployed (figure 5.1, panel a). About 23 percent of the population are inactive either because they are enrolled in school1 (22 percent) or because they are retired (1 percent). The remaining 10 percent are “Not in Education, Employment, or Training” (NEET) (see box 5.1 for definitions of various labor market terms). The most common reasons that respondents gave for being NEET were being a housewife, being unfit to work, or having been discouraged from working (figure 5.1, panel b). Unemployment rates are generally low, and inactivity varies very little across levels of education achieved. Unemployment is up to 6 percent for those with tertiary education, and the rate of NEET varies between 11 percent for people with no formal education and those with senior high school (SHS) education and 6 percent among tertiary graduates (figure 5.2). The transition from school to work is very slow. Individuals ages 35–44 have the highest employed rate. Whereas unemployment and NEET rates vary little across age groups, inactivity declines significantly (by about 28 percentage points) between the age 20–24 and 25–34 cohorts and falls by 7 additional percentage points for those ages 35–44 (figure 5.3). Although this trend might be explained by a change over time of the labor market structure, it also shows (together with the prevalence of late school entry and late completion) a slow transition from school to work.

Box 5.1 Definitions of Labor Market Terms Used in the Skills Toward Employment and Productivity (STEP) Survey Ghana’s labor force includes people ages 15–64, both employed and unemployed (and those seeking a job). The employed labor force includes those working for pay, those who have found a job but are not working because they are sick or waiting to start their new job, those working for profit, and those in apprenticeships. The unemployed labor force includes those who are looking for job and who have been laid off for 30 days or less. The employment/unemployment rate can be computed as share of employed/unemployed people over the whole population aged 15–64 or over the labor force (which excludes the inactive population). The inactive population includes people enrolled in school and those who are “Not in Education, Employment, or Training,” or NEET. The NEET rate is defined as a share of NEET over the 15- to 64-year-old population, including both the active and inactive population. The inactive subgroup is ultimately broken down to distinguish between married and unmarried people. The underemployed are those working less than 40 hours a week (considering the primary and secondary occupations together) and willing to work more hours. Underemployment is defined both as a share of the active labor force and as a share of the employed labor force only. A further distinction is made between those employed in the formal sector and those working in the informal sector. The STEP survey defines informal sector workers as unpaid workers (mainly employed in family businesses), the self-employed and wageworkers who report not having any social security or benefits, or informal wageworkers. The rest of the employed population constitutes the formal sector, made up predominantly of wageworkers. box continues next page

Box 5.1 Definitions of Labor Market Terms Used in the Skills Toward Employment and Productivity (STEP) Survey (continued)
Occupations are classified into three categories on the basis of the level of skills required. Low-skilled occupations include agricultural, forestry, and fishery workers; craft and related trades workers; plant and machine operators and assemblers; and elementary occupations. Mid-skilled occupations include technicians and associate professionals; clerical support workers; and service and sales workers. High-skilled occupations include managers and professionals. Finally, the economic sectors are classified in four groups: (i) agriculture, fisheries, and mining; (ii) manufacturing; (iii) low-to-mid-value-added services; and (iv) high-value-added services. The low-to-mid-value-added services sector includes electricity, gas, steam, and air conditioning supply; water supply and sewage; waste management; construction; the wholesale and retail trade; transportation and storage; accommodation and food services; information and communication; arts, entertainment, and recreation; other services activities; and the activities of households and extraterritorial organizations and bodies. The high-value-added services sector includes financial and insurance activities; real estate activities; professional, scientific, and technical activities; administrative and support service activities; public administration and social security; and education, human health, and social work activities.

Wage Employment, Self-Employment, and Formality Most of the employed labor force works in the informal sector, either as selfemployed (66 percent) or as informal wageworkers (20 percent).2 In fact, only 15 percent of the employed population works as salaried workers in the formal sector. However, this trend is changing: younger generations are less likely to be self-employed and more likely to be salaried workers, with either formal or Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

informal firms. Nevertheless, still more than 95 percent of the youngest age cohort (20- to 24-year-olds) work in the informal sector, most of them as informal wageworkers rather than self-employed (55 percent) (figure 5.4). Education is strongly associated with employment status, as shown in figure 5.5.

share increases to 99 percent for those who do not have any formal education (86 percent as self-employed and 13 percent as informal employees).
Occupation Type Informality is synonymous with low-skilled occupations. Only 13 percent of the employed population works in high-skilled occupations, mainly in the formal sector (figure 5.6). Conversely, the majority is employed in low-skilled (39 percent) and mid-skilled occupations (48 percent). The prevalence of workers employed in low- or mid-skilled occupations is relatively higher among the self-employed than among informal wageworkers. Increasing education leads to better occupations. Nevertheless, although this is true for SHS and/or tertiary graduates, those with primary education and those with no formal education are equally distributed among low-skilled or mid-skilled jobs (figure 5.7). Junior high school (JHS) graduates do slightly better, with about 2 percent more working in mid-skilled occupations and about 4 percentage points fewer in low-skilled occupations. The scenario changes for those with an SHS education, with 18 percent working in high-skilled occupations and only 32 percent in low-skilled occupations. The contrast in terms of high-skilled jobs is even more pronounced for those with a tertiary education, for whom the figure reaches 70 percent, with only 6 percent working in low-skilled occupations.
Economic Sector of Occupation The largest share of the employed population works in services (61 percent in low-to-mid-value-added services and 17 percent in high-value-added services). The smallest share works in manufacturing (about 10 percent), followed by Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

11 percent in agriculture, fishery, and mining combined. Almost all of the occupations in the manufacturing sector and the agriculture, fishery, and mining sector are low-skilled occupations (figure 5.8). Education attainment increases in line with employment in higher-value economic sectors. Almost half of the workers in the agriculture, fishery, and mining sector have no formal education (53 percent) compared to 21 percent in the manufacturing sector and 28 percent in the low-to-mid-value-added services sector (figure 5.9). The education level of employees in the manufacturing sector is very similar to that of workers in the low-to-mid-value-added services sector.

completing SHS makes a difference, given that about 29 percent of SHS graduates work in the high-value-added services sector compared with 3 and 8 percent for those with primary and JHS educations, respectively (figure 5.10). Nevertheless, 8 percent of SHS graduates still work in the low-to-mid-value-added services sector.
Gender Disparities On average, labor force participation is very similar for men and women. However, when distinguishing between married and unmarried men and women, we find a significant gender gap among those who are married. About 89 percent of married men are employed compared with about 77 percent of married women. Married women are more likely to be out of the labor force than men and more likely to be NEET in their capacity as housewives (see figure 5.11). The difference between the labor market status of males and females across age cohorts is not as significant as might be expected (see figure 5.12). Notably, the percentage of females who are NEET is highest for the 20–34 age group, which likely correlates to age-specific life events such as childbearing rather than a change over time in the women’s labor market status. Increasing access to childcare and flexible work options might help to expand labor market participation and opportunities for women. Although women are as likely as men to be employed, the gender gap is very pronounced in the quality of employment. At all ages, females are more likely to be self-employed than men. About half of the male working population is

Chapter 6
The Use of Cognitive Skills, Job-Specific Skills, and Literacy
Introduction To the extent that workers’ productivity depends on their skills and is reflected by their wages, individuals with more skills should expect higher returns from their labor market participation. Most studies investigate the returns to investments in human capital using the education qualification attained. Only a few recent studies examine the returns to skills (Leuven et al. 2004; Tyler 2004). The data arising from the Skills Toward Employment and Productivity (STEP) survey provide a unique opportunity to analyze skills across a range of dimensions and measure their implications for an individual’s well-being and relative opportunity in the labor market. As mentioned in chapter 3, the STEP survey focuses on three types of skills: (i) cognitive skills (self-reported and direct assessment); (ii) socioemotional skills; and (iii) job-specific skills. The following section will assess the distribution of each category of skill across population subgroups and thereafter proceed to an analysis of the returns to skills.
The Use of Cognitive Skills: Overall Use and Intensity of Use The use of cognitive skills refers to the overall use of reading, writing, and numeracy skills either in daily life or at work.1 Almost everybody uses numeracy skills regularly, at all levels of education. Conversely, the regular use of reading and writing skills is positively correlated with education. The large majority of survey respondents who attended tertiary education read and write regularly. This can be compared with the population with a primary education who reported using their reading (64 percent) and writing skills (60 percent) on a regular basis (figure 6.1).

The Use of Cognitive Skills, Job-Specific Skills, and Literacy
The use of reading and writing skills has increased greatly over time, especially among people with low educational attainment. In fact, the highest disparity in the use of skills by age groups is among people who completed only primary education. In the youngest cohort with only primary education, 89 percent use their writing skills and 90 percent use their reading skills. However, less than half of the oldest age cohort uses them, with only 40 percent using their reading skills and 41 percent using their writing skills (figure 6.2). The intensity of the use of various skills is linked to the level of proficiency and increase with the level of education attained. Overall, 31 percent

of the population reported not using their reading skills at all. Among the 69 percent using them regularly, half of the population read with low intensity, 24 percent read with medium intensity, and 29 percent read with high intensity. Among those with no formal education, 87 percent do not read at all, and 11 percent read only very short documents, whereas only 1 to 2 percent read intensively (figure 6.3). Reading intensity is higher among graduates of senior high school (SHS) and tertiary education. Nevertheless, there are still 40 percent of SHS and 19 percent of tertiary graduates who do not read or who do so rarely. With regard to writing skills, about 35 percent of the adult population reported not writing regularly. Furthermore, most people use their writing skills less regularly than their reading skills. As in the case of reading skills, the use of writing skills increases with education. Writing skills significantly improve for those completing primary education and for those completing SHS and tertiary education. Nevertheless, even among those who completed tertiary education, almost half write only with low intensity (figure 6.4). The use of skills is strongly related to employment status. Formal employment requires an intensive and frequent use of reading skills. More than 84 percent of Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

formal employees use their reading and writing skills on a daily basis compared with about 41 percent of informal employees and about 21 percent of the selfemployed (figure 6.5). Although the use of numeracy skills is almost universal within all employment groups, computer use is low across the entire workforce. More than one-third of formal wageworkers reported using their computer skills at work, whereas only 11 percent of informal wageworkers and less than 3 percent of the self-employed reported using them (figure 6.5). Finally, the percentage of workers who use reading and writing skills and computers is significantly higher among those who work in the high-value-added services sector than in any other sectors (figure 6.6).

Job-Relevant (or Task-Related) Skills Job-relevant skills are task related and consist of a combination of cognitive and socioemotional skills. The STEP survey includes information on whether employed people perform any of the following tasks at work: repairing and maintaining electronic equipment, operating heavy machinery, making presentations, and supervising others. The survey also asked about the intensity of their computer use, solving and learning from problems, physical tasks, and autonomy and repetitiveness. For each skill, a score ranging from 0 to 3 was computed, with 0 being equivalent to not using the skill, 1 for low use, 2 for medium use, and 3 for high use. The data also include the respondents’ self-reported information of the educational attainment required to do their job and the time required to learn how to do it.

Working in the formal sector implies regularly learning new things at work and more frequently involves supervising others’ work and making presentations. Conversely, work in the informal sector is less cognitively but more physically demanding and is more repetitive. Self-employed workers reported having more autonomy at work and performing more repetitive tasks than wageworkers (figure 6.7).

Socioemotional Skills The survey includes information on socioemotional skills, more specifically on the “Big Five” personality traits (openness, conscientiousness, extraversion, agreeableness, and stability), grit, and hostile bias. Hostile bias is a behavioral characteristic that measures how often the individual believes that others are hostile to him or her. In addition, the survey also asks about risk and time preferences. Risk lovers have a high score, whereas risk-averse people score low. For time preference, those with a high score are more future oriented and those with a low score are more present oriented (more detail about the socioemotional skills can be found in appendix B). This self-administered section was presented in English to the full survey sample. Because of low literacy, about 37 percent of respondents were not able to answer. Therefore, the results are not representative of the whole urban population because those who did not complete this section were not randomly selected and have different characteristics than those able to answer. For example, nonrespondents are older, less educated, and more likely to work in lowskilled occupations than those able to answer (see table D.5 in appendix D for further details). All questions relating to the measurement of socioemotional skills were answered on the following scale: 1 corresponding to “Almost never,” 2 corresponding to “Some of the time,” 3 corresponding to “Most of the time,” and 4 corresponding to “Almost always.” As reported in figure 6.8, the respondents

scored around 3 in nearly all the personality traits, which means that most of the time they identify themselves positively with the Big Five and grit. Among them, extraversion is the trait with the lowest average score (2.5) and conscientiousness the one with the highest average score (3.2). On average, respondents located on the middle to low level in the hostile bias scale. With respect to their preferences, they are on average more likely to be present than future oriented and more likely to be risk averse than risk loving (figure 6.9). There is a growing literature underscoring the role of socioemotional skills in education and labor market achievement. Figure 6.10 illustrates the estimated coefficients for socioemotional skills as factors associated with the number of school years completed, controlling for sociodemographic characteristics (age, gender, maternal education, socioeconomic status at age 15, and the region of residency). Similarly, in figure 6.11 the same associations are reported for the estimated probability of attending at least SHS. Finally, figure 6.12 illustrates the association between socioemotional skills and the probability of being employed, being self-employed (versus wageworkers), and employment in midto high-skilled occupations (versus low-skilled occupations). Overall, the results suggest that socioemotional skills are closely associated with educational attainment (figures 6.10 and 6.11). More specifically, a higher self-reported score relative to the Big Five personality traits is associated with higher educational attainment. Among the personality traits, conscientiousness has the highest positive correlation, followed by extraversion, openness, and agreeableness. Grit and emotional stability are also positively associated but in smaller magnitude.

The results are in line with the literature that relates better educational outcomes to those with higher levels of the Big Five personality traits and grit. Furthermore, those who are more trustful, more present oriented, and less risk averse have a higher probability of studying one additional year (figure 6.10). The results are substantially confirmed when analyzing the probability of completing at least SHS education (figure 6.11). In this case, a change in one score unit of conscientiousness is associated with 14 percentage points on the probability of completing SHS or tertiary attainment. As with years of education, higher agreeableness and stability levels, perceiving others as less hostile, being more present oriented, and being a risk lover increase the probability of completing higher levels of education Finally, we present the results of the association of socioemotional skills and the probability of being employed, being self-employed (versus wageworkers), and working in mid- to high-skill occupations (versus low-skill occupations).

(once we controlled for education, one of the control variables included in the model). However, noncognitive skills seem to play a role in determining the quality of the occupation. Individuals with higher levels of the Big Five personality traits and lower levels of hostile bias are less likely to be self-employed (and therefore more likely to be wageworkers). Interestingly, the only socioemotional skill that is significantly associated with having a mid- to high-skill occupation is emotional stability, which relates to the ability to cope with stress. Included in mid- to high-skill occupations are managers, professionals, clerical support workers, and service and sales workers.
Reading Literacy Assessment The reading literacy assessment consists of three parts, all administered in English. The first part (Reading Components) evaluates foundation reading skills, including word meaning, sentence processing, and passage comprehension. The second part (Core Literacy Test) consists of a core literacy assessment that is intended to sort the least literate adults from those with higher reading skill levels. The Core Literacy Test has a total of eight items, and respondents with three or more correct responses are regarded as having met a minimum reading literacy threshold (see box 6.1 for more information on the Core Literacy Test). The third part (the Literacy Exercise Booklets) is administered only to those respondents who have passed the Core Literacy Test (see box 6.1). The Literacy Exercise Booklets use a variety of questions drafted around daily life situations. They require respondents to carry out different types of tasks such as accessing and identifying information (in both text-based and nonprose materials such as tables, graphs, and forms), integrating and interpreting information, and evaluating information by assessing the relevance, credibility, or appropriateness of the material for a particular task. Overall reading proficiency scores are reported on a scale ranging between 0 and 500, which is divided into five levels, with level 1 characterized by the least demanding tasks and level 5 the most demanding. For each respondent, 10 plausible values were generated. All survey respondents were asked to answer the Core Literacy Test. Nevertheless, the nonresponse rate is quite high—about 38 percent (figure 6.13). There are two types of nonrespondents: those who fail to complete the section because they are unable to read or understand English (“No English”) and those who did not complete the tests for multiple reasons (“Missing”).2 Those with no English literacy represent 21 percent of the adults, whereas the missing group represents 17 percent of the sample. The three groups (those who answered the Reading Components and the Core Literacy Test, the group with no English literacy, and the missing group) are significantly different; therefore, the findings summarized may not be applicable to the entire urban sample. For example, those who answered are more likely to speak English at work (57 percent versus 18 percent of the missing and those with no English together) and to read and write with higher intensity than those who did not answer the test. Compared to the nonrespondents, they have higher Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

Box 6.1 What Does It Mean to Pass the Core Literacy Test? A sizable proportion of adults reported that they read regularly, even though they did not pass the minimum literacy threshold of the Core Literacy Test. One reason could be that the tests are in English whereas many individuals mainly speak a local language. Only 1 percent and 40 percent speak English as their main language at home and at work, respectively (figure B6.1.1). In contrast, Akan is widely used in daily life. Thus, although the literacy assessment captures reading proficiency in English, the self-reported measure could be a better proxy of respondents’ capacity to read and write in their daily life in their local language. Even though only 40 percent of adults speak English at work, 58 percent of the urban adults report being able to speak and to read and write English well enough to work in a job that requires them to do so (figure B6.1.2). As expected, the vast majority (90 percent) of those with no English and a third of those who failed the Core Literacy Test are unable to write, read, or speak in English at work. In contrast, among those who passed the Core Literacy Test, about 96 percent report being able to write, read, and speak English at work. (figure B6.1.3). Notably, about half of those who failed the Core Literacy Test report being able to use English at work—that is, there is a discrepancy between the self-reported and measured skills. Poor English language literacy does not seem to prevent people from getting a job (figure B6.1.4). Only 12 percent report that the lack of English kept them from getting a job. However, those who speak English at work tend to have better-quality jobs. They are more likely to be formal employees in high-value-added sectors and in high-skill occupations. They also earn on average 248 GHS per month (or 60 percent) more than those who do not speak English at work.

Although one-third of the missing group use English at work, 6 percent of those with no English literacy do. Furthermore, almost three-quarters (72 percent) of those with no English did not complete any formal education, whereas only 18 percent of the missing group has no education and 17 percent completed at least SHS. Also a lower percentage of those with no English reported using their reading and writing skills compared to those in the missing group.
Reading Components The Reading Components section evaluates the extent to which participants can recognize the printed forms of common objects (print vocabulary), comprehend sentences of varying levels of complexity (sentence processing), and comprehend the literal meaning of connected text (basic passage comprehension).

The overall performance is low in all three sections (figure 6.14). Sentence processing has the highest percentage of correct answers (41 percent) at all education levels, age groups, and levels of self-reported use of skills. However, it is also the section with the highest percentage of nonresponse (19 percent) compared to 11 percent in print vocabulary and 9 percent in passage comprehension. In passage comprehension only 38 percent of the items are answered correctly. The lowest performance is in print vocabulary with only 21 percent correct answers. Respondents reporting to be medium- to high-intensity readers or writers answer a higher percentage of correct answers in both the sentence processing and passage comprehension tests. The only exception is for the print vocabulary component, which does not vary much across groups (figure 6.15, panels a and b). The percentage of correct answers increased with the education level achieved (figure 6.16, panel a), and younger cohorts performed better than older age groups (figure 6.16, panel b). Those with no formal education answered fewer than 24 percent of the questions in each section correctly. Even though the results improve across all levels of education, there is a more noticeable difference between junior high school (JHS) and SHS graduates. Those with a primary or a JHS education answered less than one-third of the test questions correctly, whereas those with an SHS or a tertiary education answered about 44 percent of the passage questions and 46 percent of the sentence questions correctly. However, even among those with tertiary education, the scores on the print vocabulary section are low, with an average of only 23 percent correct answers—only 4 percentage points Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

This might suggest an improvement of the literacy level over time or might simply reflect a greater familiarity of the younger generations with taking assessment tests.

Core Literacy Test The Core Literacy Test contains eight basic literacy questions and is designed to identify those with a minimum level of literacy, namely those who can answer at least three of the eight questions correctly. Only 42 percent of the respondents pass this threshold; 17 percent do not answer because they are unable to read the questions, and 22 percent are missing for other reasons. When taking out the missing group and adding those with no English to the group that did not pass the Core Literacy Test, the data show that only half of the population passed the Core threshold (figure 6.17, panel a). The distribution of correct answers has a U shape: about 15 percent of the sample answered all questions correctly, and 14 percent had no correct answer. The median value is about three to four correct answers (figure 6.17, panel b). This section provides a profile of those who pass and those who fail the test (considering together those who failed and the “No English” subgroup) in terms of gender, age, education level, language, labor and employment status, self-reported use of skills, socioemotional characteristics, and performance on the Reading Components and Core Literacy Tests. Full results are reported in appendix D. Young men with at least an SHS education are most likely to pass the test. More than half of those who pass the exam were male and seven years younger than the average. Ninety-three percent of those who failed the test had a JHS education or lower (42 percent have no formal education and 33 percent attended JHS), whereas about 57 percent of those who passed the test had at least an SHS education and about 21 percent have tertiary education. Notably, about 81 percent of those who passed the exam had received early childhood education compared with 47 percent of those who failed.

The variables for socioeconomic status (SES) and whether English was the respondent’s main language are both highly correlated with the probability of passing the test. About 30 percent of those who failed the test have been poor during their adolescence, and only 15 percent of them passed the Core Literacy Test. Although English is Ghana’s official language, only 1 percent of all respondents reported speaking English at home and 40 percent at work. Because the reading test was in English, it is not surprising that a higher percentage of those who passed the test than of those who failed reported English as the main language at home and at work. Among those who passed the test, 73 percent use English at work compared with 17 percent of those failing the test. Furthermore, the probability of succeeding is higher for those working in the formal sector and in high-skilled and better-paid occupations. Within the employed group, 81 percent of those who failed the test are self-employed and only 3 percent are formal wageworkers. More than half work in mid-skilled occupations and only 3 percent are in high-skilled jobs. In contrast, 38 percent of those who passed the exam were self-employed and 34 percent were formal wageworkers. One-third worked in high-skilled occupations and earn on average 274 GHS (approximately US$80) more per month than those who failed the test. Self-reported measures of the use and intensity of use of reading and writing skills is highly correlated with the results of the Core Literacy Test. Nevertheless, a significant number of people who reported using their skills regularly failed the test. Indeed, of those who did not pass the test, about 42 and 38 percent, respectively, reported using their reading and writing skills. The (self-reported) intensity of use of reading and writing skills is a better predictor of the test results. Indeed, 41 percent of those who pass the test are regular (high-intensive) readers compared to Stepping Up Skills in Urban Ghana • http://dx.doi.org/10.1596/978-1-4648-1012-1

only 12 percent of those who fail the test. Similarly, 83 percent of those who fail the test self-report being low-intensity writers, and the percentage of low-intensity writers is lower (63 percent) among those who did not pass the test. The differences among respondents are more significant when we compare those who successfully pass the Core Literacy Test with those who do not answer any questions correctly. On average the latter have lower education (half of them have not completed any formal education); only 5 percent speak English at work and none of them use it at home. Eighty percent of these respondents are employed and most of them (79 percent) are self-employed. Fewer than one-third of them report using their reading skills (only 9 percent of them are high-intensive readers) or their writing skills (only 2 percent of them are high-intensive writers).
Literacy Exercise Booklets Those who succeed in the Core Literacy Test are asked to take the Literacy Exercise Booklets, which provide a more in-depth evaluation of reading skills. The Literacy Booklets are scored on a scale that ranges from 0 to 500 and includes six literacy levels from “below level 1” to level 5. The description of the literacy competencies for each one of the levels is provided in table 3.2. The “below level 1” includes those who failed the Core test (half of the original sample) and an imputed score for those who did not answer (about 17 percent of the eligible sample).3 The average performance on the Literacy Exercise Booklets is very poor. Most of the population (61 percent) is below level 1, 18 percent reach level 1, 17 percent reach level 2, only 4 percent of the respondents reach level 3 or level 4 (reported together in figure 6.18), and no one is in level 5. The level achieved is positively correlated with the number of correct answers in the Core Literacy Test. Those with a reading proficiency below level 1 are those who did not reach the minimum threshold set for the Core Literacy Test (three correct answers) (about 33 percent) and the group with no English literacy (34 percent). However, 11 percent of those below level 1 passed the Core test but performed poorly in the subsequent assessment. On the other hand, those in level 3 and 4 answered correctly at least six of the Core test questions. Indeed, 93 percent of them correctly answered seven or more questions in the Core test (figure 6.19). Like those passing the Core test, those scoring high in the literacy assessment are younger, have higher education (SHS or tertiary), and are more likely to work in the formal sector, to use their reading and writing skills more intensively, and to use English more frequently at work and at home (figure 6.20). Performance on the Literacy Exercise Booklets is correlated with the selfreported reading intensity as well. For example, among those who passed the Core Literacy Test with three to six correct answers, more of those who self-reported using their reading skills with high intensity reached level 1 than did those who read with low intensity (52 percent versus 43 percent) and level 2 (25 percent versus 14 percent) (figure 6.21). Similarly, among those who completed the whole Core Literacy Test correctly, 27 percent of the high-intensity readers reached levels 3 and 4 on the Literacy Exercise Booklets versus only 7 percent of those who selfreported reading with low intensity.

Developing Skills beyond Education: Training and Apprenticeships In Ghana 32 percent of the adult population living in urban areas continue their skills development by participating in skills training courses, by achieving industry- or government-recognized certificates, and through informal apprenticeships. Apprenticeship is the most common: in the 12 months prior the survey, 25 percent of adults participated in an apprenticeship, whereas only 6 percent received a recognized training certificate and less than 7 percent participated in a formal training course of at least 30 hours. It is worth noting that, although apprenticeship is more common for older age cohorts (figure 6.22, panel b) and among those with JHS or lower education, training is more common for those with tertiary education (figure 6.22, panel a). After completing each level of formal education, students might continue with the next level of formal education or leave the education system and take an apprenticeship instead. As shown in figure 6.23, apprenticeship does not replace formal education. Indeed, most of people who complete an education level either decide to drop out of school or continue in formal education. Among those completing primary education, only 4 percent left the education system for an apprenticeship, 65 percent start JHS, and 10 percent drop out. The percent of those opting for an apprenticeship is the highest among those completing JHS: 13 percent of them choose an apprenticeship while 30 percent continue to SHS. Formal workers generally have more training outside the formal education system, whereas apprenticeship is more common among the self-employed. Twenty-six percent of formal workers participated in work-related or personalrelated skill training courses, 25 percent participated in apprenticeships, and 14 percent achieved an industry- or government-recognized certificate. About 38 percent of the self-employed participate in an apprenticeship (figure 6.24). Apprenticeships are also more common among those working in low-skilled occupations and in the manufacturing sector (figure 6.25). The most common

Notes 1. See appendix B for a definition of skills use and intensity of use variables. 2. This group includes for example those refusing to begin the test booklet (because of time constraints, not wanting to bother, or other general refusal), those who began the booklet but refused to continue, or those who were unable to continue because of an unusual circumstance. 3. The literacy proficiency is modeled using the item response theory in a scale that ranges from 0 to 500. Each point in the 500-point scale has a probability of completing the tested item. The higher the score for a given individual, the more proficient the individual is. The design divides the test into partially linked booklets so that only a portion of the entire battery of items is administered to a single individual. Otherwise, the assessment would be too long if every individual had to take the entire battery of items. In order to estimate the proficiency level, multiple literacy proficiency scores (plausible values) are estimated for each individual on the basis of response to the items as well as some background information. Only those who passed the Core had to respond to this booklet, providing a finer evaluation of reading skills for the most literate respondents. However, imputation allows estimating the reading proficiency level for all respondents.

The Returns to Education and Skills: Building the Job-Relevant Skills That Employers Demand
Introduction This section discusses the payoffs of education and skills in term of earnings and job opportunities. This section answers the following questions in detail: To what extent does education explain better labor market opportunities and higher earnings? (And at which educational level does further investment in education not generate a premium?) Do skilled workers have higher earnings? Which skills yield the best labor market opportunities and higher earnings? The analysis carried out in this section involves descriptive statistics and two multivariate regression models. The first model is a Mincer equation for earnings. The second is an employment participation model. These models look at the correlation between education and/or skills and monthly earnings and employment status, respectively. For the two models we tried different specifications. The first specification reported in the figures and tables below does not include any controls and reports only the “pure” correlation between monthly earnings (or self-employment status) and the education variables (either years of education or education levels where those with no formal education or incomplete primary are used as a reference category). In the second model, we control for a core set of sociodemographic variables including age, gender, work experience, economic sectors, and regional dummies. Then we include a set of controls one at time to see how education returns vary when taking into account (i) the results of the proficiency assessment test (the number of correct answers in the Core Literacy Test and the percentage of correct answers on the Reading Components); (ii) individual personality traits; (iii) the intensity of the use of cognitive skills; (iv) the intensity of the use of job-specific skills (cognitive challenges, physical work, autonomy and repetitiveness,

presentation skills, supervision skills, and the use of computer at work); and (v) all of the controls together. All control variables are defined in appendix C and full results are reported in appendixes D and E.1
Returns to Education and Skills Our data show some returns for continued education. An additional year of education increases monthly earnings by 3–7 percent (figure 7.1). Notably, primary education has no distinguishable premium in terms of earnings, considering those with no formal education or incomplete primary education as a base category. We also found that market rewards for primary education and junior high school (JHS) are lower than those for senior high school (SHS) and higher levels of education.2 For higher education, the premium is between 16 and 63 percent for SHS graduates and between 77 and 156 percent for tertiary graduates compared to workers with no formal education or incomplete primary education. The premium for JHS is much lower (between 10 and 40 percent). Faced with uncertain and binding constraints, people are more likely to drop out of school before SHS. In fact, as mentioned above, the majority of the population (66 percent) leaves the education system before SHS.

The Returns to Education and Skills: Building the Job-Relevant Skills That Employers Demand
Overall skills are an important determinant of earnings beyond education. In fact the returns of any additional year of education decrease by 2 percentage points after all skills have been controlled for. The best-paid jobs are those that require intensive writing and job-specific skills such as the use of the computer and also involve cognitive challenges and supervision responsibilities. Out of the “Big Five” personality traits (openness, conscientiousness, extraversion, agreeableness, and stability), only the estimated coefficient for conscientiousness is statistically significant (see appendix E). Notably, even after accounting for all skills (cognitive, socioemotional, and job-specific skills), SHS and tertiary education have a significantly higher earnings premium. The returns to education and skills vary a great deal according to types of employment, with the lowest returns among self-employed and the highest among formal wageworkers. One additional year of education increases the monthly earnings of the self-employed by 1–5 percent, those of informal wageworkers by 4–6 percent, and those of formal wageworkers by 7–10 percent (see figure 7.2 and appendix E). Earnings differentials are a typical feature of labor market segmentation. More specifically, an earnings gap between informal sector workers and equally qualified formal wage and salaried employees can be interpreted as a measure of the degree of labor market segmentation (Schultz 1961; Becker 1962; and Mincer 1962). In countries such as Ghana, the formal economy is not capable of

providing enough good, high-wage jobs. The majority of self-employment consists of informal income-earning activities and small businesses pursued by individuals who are unable to secure (formal) wage employment. The key to accessing the formal wage sector is once again education (figure 7.3). About 44 percent of workers employed in the formal sector have a tertiary education and 32 percent have graduated from SHS, whereas only 24 percent have a JHS education or less. In Ghana the formal sector mainly consists of high-value-added service companies, which require a highly qualified labor force. Only tertiary education has a significant premium in the formal sector given the selection bias. This means, for example, that individuals with higher ability and motivation are more likely to choose and complete tertiary education and receive higher earnings. Graduates of SHS and JHS and those who have completed primary education all have the same probability as workers with no formal education of being self-employed (figure 7.4). Furthermore, self-employed workers use their numeracy skills more intensively than all other employees and perform fewer repetitive tasks and use the computer less. With respect to socioemotional skills, only grit is positively correlated with being self-employed (see appendix E).

Returns to Education: Is There a Gender Premium? The returns to an additional year of education are very similar—between 3 and 5 percent for men and between 3 and 6 percent for women (figure 7.5). The returns to primary education are not significantly different from zero for both men and women. For males only tertiary education guarantees a premium, whereas for women education starts to pay off starting from JHS. The market reward is always higher for women than for men. In fact, after controlling for all skills, the returns to tertiary education are 98 percent for females and 73 percent for men. This gender gap might be misleading because it does not take into account that both labor market participation and educational attainments are lower for women.

The Returns to Education and Skills: Building the Job-Relevant Skills That Employers Demand
Notes 1. We recognize the possible limitations of this estimation procedure in terms of possible multi-collinearity. Furthermore, a causal interpretation of the finding shown in the following sections is not either legitimate or claimed. 2. This is consistent with recent studies for many low-income countries showing that the returns to primary education are lower than those for the secondary level—see Mwabu and Schultz (2000) for South Africa, Kingdon (1997) for India, Siphambe (2000) for Botswana, among others. For example, Moll (1996) argues that a decline in school quality and changes in demand and supply factors largely account for the low returns to primary schooling in South Africa.

Mismatch of Skills: A Measurement Issue and Unexploited Potential at Work
Mismatch between Self-Reported Skills and Core Literacy Test Results: Does Language Matter? Several of the cognitive and job-specific skills captured in the Skills Toward Employment and Productivity (STEP) survey are self-reported. These selfreported measures relate to the intensity of use of these skills at work or outside work. The self-reported reading skill measure can capture a subjective assessment of the mastery and usefulness of the skill, but a key question is how well these assessments fit in with some objective measures such as the Core Literacy Test. If subjective and objective measures reflected a real ability, those reporting that they read frequently should also be able to pass the Core test. However, although 69 percent of adults reported reading regularly, only 42 percent of the population passed the Core test. This considerable mismatch is due to both the high nonresponse rate for the objective literacy assessment (in contrast to low missing values for the subjective measurements) and the difficulties encountered in the Core test because of the language used. As a consequence, the Core test is more likely to be a measure of the individual’s English literacy than of his or her general reading skills. Notably, the self-reported assessment of the use of skills does not specify a particular language, and respondents might indeed take it to mean any of the local languages widely used not only in the rural Ghana but also in urban areas. There is a considerable mismatch between the self-reported and the assessed reading skills (that is, between those reporting that they read and those passing the Core test). Indeed, about 26 percent of those who reported reading did not pass the Core test. Still, those not passing the Core test and reporting reading are 41 percentage points more likely to speak English at work (74 percent use English at work whereas 33 percent do not) and slightly more likely to speak English at home (close to 2 percentage points).

Mismatch of Skills: A Measurement Issue and Unexploited Potential at Work
The mismatch between self-reported and measured literacy is not randomly distributed (see appendix F). Those who failed the Core test and reported being able to read are more likely to be women, to be less educated, to work in low-skilled occupations and less in high-value-added sectors, and to earn about 41 percent less than those who report being able to read and also pass the Core test. The difference in the intensity of use of reading skills might definitively explain the skills mismatch between self-reported and objective measures of skills. The intensity of use of the skill is a more closely related measure to the Core test. Among those who self-reported reading with low intensity, 66 percent failed the text and 30 percent passed it. Only 14 percent of those who failed indicated reading frequently.
Are There Unexploited Skills in the Workforce? Among the employed population, a group of individuals reported using their cognitive skills and computer skills in their daily life (that is, using skills outside the realm of a paid job, including a family business) but not at work. This group of people might represent unexploited human capital that the labor market is not able to absorb. In this section, we analyze the profile of those who report using their skills only outside work and those who use their skills at work. Women—more frequently than men—are likely to be literate but employed in occupations not requiring the use of reading and writing skills. Similarly, there is an unexploited potential among the youngest generations who are able to use computers but work in jobs where this skill is not demanded. Being able to use their computer skills at work would guarantee them a monthly income 38 percent higher than they receive in their current occupations. Those using a skill only at home are less likely to work at a high-skilled occupation and in a high-value-added sector and are more likely to work at a mid-skilled occupation and a low- to mid-value-added sector. The greatest unexploited potential, as expected, is among those in low-skilled occupations and low-value-added sectors. For example, about 34 percent of the self-employed read at home but never use their reading skills at work. Conversely, only 6 percent of employees in the formal sector have a skills mismatch. The level of education seems to be closely related to the use of certain skills at work. The level of education of those who read, write, or use computers only at home is lower than for those using their skills at work. The latter are predominantly senior high school (SHS) graduates. The fact that the mismatch of skills occurs more at lower levels of education than SHS might suggest that SHS provides students with the right skills demanded by the labor market and that SHS education provides a clear signal to employers of the cognitive skills potential employees have.

Mismatch of Skills: A Measurement Issue and Unexploited Potential at Work
To a certain extent the mismatch of skills used at home but remaining unused at work does reflect the quality of those skills rather than an unexploited potential. Indeed, on average those using their (reading, writing, and computer) skills only at home performed worse on both the Reading Component and the Core test than those who also use them at work. To sum up, there is a clear connection between the availability of skills and the use of skills at work, whether the skills are cognitive or work related. Moreover, the use of the skills at work appears to explain the difference between objectively measured and self-reported skills. Those who work in low-skilled occupations are more likely to report higher skills than are measured objectively through the literacy assessment.
Conclusions and Looking Forward In conclusion, the study has provided evidence in a number of areas that are relevant for policy makers, for setting government investment priorities and also for continued diagnostic work. The study demonstrated the positive impact of early childhood education on schooling, on jobs, and on earnings. The country continues to demonstrate progress in education attainment at all levels, but there is also evidence of persistent disparities in attainment by income, gender, and geographical location. There are also continued difficulties with delayed education, dropout, and low completion rate—mostly for the poor, given the high opportunity costs. Importantly, improved education attainment did not bring about comparable improvements in cognitive skills as measured by the adult literacy assessment. The labor market also shows persistent segregation between employment in higher-value sectors, where employees have higher attainment and education pays off, and employment in sectors such as agriculture, fishing, and mining, where there appears to be an equilibrium of low education and low income. In the first group, employees demonstrate and report higher skills. There is a clear connection between the availability of skills and the use of skills at work, whether the skills are cognitive or work related. Moreover, the use of the skills at work appears to explain the difference between objectively measured and self-reported skills. Those who work in low-skilled occupations are more likely to report higher skills than are measured objectively through the literacy assessment. These findings offer some priorities and options for policy and investment. For the country, investment and scaled-up access and quality in early childhood education would lead to sustained long-term growth and shared prosperity. For education policy, continued investment into improved literacy and also improved socioemotional and work skills helps build the country’s human capital (increasing demand for postbasic, postsecondary education) and improved labor force. Sustainable forms of skills development should incentivize demand and supply of skills through both formal and on-the-job training.

Mismatch of Skills: A Measurement Issue and Unexploited Potential at Work
The study also offers options for continued diagnostic work. The household survey data could help carry out more in depth analysis on the return to education and skills (and the role of training), on skills formation (and how cognitive and noncognitive skills correlate), and cross-countries comparison with other similar datasets. Finally, this research could be complemented with a STEP employer survey that focuses on the demand for education and both cognitive and noncognitive skills by both public and private employers in Ghana’s key economic sectors.

Environmental Benefits Statement The World Bank Group is committed to reducing its environmental footprint. In support of this commitment, we leverage electronic publishing options and print-on-demand technology, which is located in regional hubs worldwide. Together, these initiatives enable print runs to be lowered and shipping distances decreased, resulting in reduced paper consumption, chemical use, greenhouse gas emissions, and waste. We follow the recommended standards for paper use set by the Green Press Initiative. The majority of our books are printed on Forest Stewardship Council (FSC)–certified paper, with nearly all containing 50–100 percent recycled content. The recycled fiber in our book paper is either unbleached or bleached using totally chlorine-free (TCF), processed chlorine–free (PCF), or enhanced elemental chlorine–free (EECF) processes. More information about the Bank’s environmental philosophy can be found at http://www.worldbank.org/corporateresponsibility.

The Skills Toward Employment and Productivity (STEP) survey is an initiative of the World Bank in cooperation with other development partners and nongovernmental agencies. STEP was carried out in more than 14 countries globally. In Ghana, the first phase of the survey, focusing on adults in urban communities, was undertaken in partnership with the University of Ghana’s Institute of Statistical, Social, and Economic Research; the Ministry of Education; the Council for Technical and Vocational Education and Training; and the Ghana Statistical Service. Stepping Up Skills in Urban Ghana provides detailed insights from the survey for policy makers. These insights cover areas including investments in early childhood education, the role of improvements in the quality of education, and the creation of incentives for economic actors to invest in on-the-job training to improve Ghana’s competitiveness and the well-being of its citizens.
