AGNES IRWIN KNOWS GIRLS. And we always have. Founded in 1869, The Agnes Irwin School is a non-sectarian, all-girls PreK-12 college preparatory school in Bryn Mawr, Pennsylvania. We provide an exceptional education where girls are truly known — and because of it, they grow into leaders, achievers, and the fullest versions of themselves.

EVERY GIRL DESERVES TO RECOGNIZE HER OWN POTENTIAL. That’s where we come in. In the classroom. At Agnes Irwin, girls are challenged by rigorous academics, inspired by innovative teaching, and supported by a dynamic, nurturing community. From Lower School through Upper School, our students experience an environment where engagement empowers, curiosity thrives, and each student is encouraged to become her best self.
On the field. Our athletics are a proud tradition of girls showing up for one another, playing with heart, and finding confidence through commitment, grit, and growth. This is a community where the excitement is real and the sidelines are loud. Where every cheer reminds our girls they belong.
On the stage. In the studio. In the rehearsal room. The arts are essential to how our students learn, express themselves, and lead. Here, girls develop artistic technique, creative discipline, and the confidence to take risks, trust their voices, and share them boldly.

“At AIS, we ensure each girl is known, cared for, and challenged. Our curriculum and teaching are grounded in research about how girls learn best. We create consistent opportunities for girls to speak up, lead, and shape their own path — ultimately ensuring that confidence becomes a skill. All of this is in service of our mission to empower girls to learn, to lead, and to live a legacy.”
