The Agnes Irwin School's Full Profile



The Agnes Irwin School says

The Agnes Irwin School is a nationally recognized all-girls' independent college preparatory school for PreK-Grade 12 that has provided outstanding liberal arts education since 1869. We offer a rigorous academic program, coupled with competitive sports and diverse visual and performing arts, and combine current educational thinking with well-established teaching practices that serve girls best. Agnes Irwin is a place where students take chances, discover their strengths, and excel across a wide range of academic subjects, athletic endeavors and extracurricular pursuits. We’re a place that’s small enough to feel like a real community, but big enough to inspire a sense of adventure. A place where girls are confident, engaged and excited about what lies ahead. At Agnes Irwin, girls not only embrace learning, they immerse themselves in it. Whether bringing original ideas to life in the Kindergarten Invention Convention, designing unique civilizations in Middle School or delivering a powerful speech in Senior Assembly, our girls eagerly embrace challenges, freely speak their minds, and learn to follow their curiosity wherever it leads – which might be somewhere completely unexpected. They hail from scores of zip codes around the Greater Philadelphia area as well as other countries, bringing a wealth of perspectives to our community. With top-notch educators and 660 students of varied backgrounds, The Agnes Irwin School empowers girls to learn, to lead, and to live a legacy. Find out more! Visit
