All High School for Girls in Pennsylvania

Charting her course.

Here she is free to explore, stretch, soar, and try anything. Agnes Irwin girls lead the way.

Upper School at Agnes Irwin is full of discoveries. Our rich curriculum provides students with a deep foundation in humanities, STEAM, wellness, arts, and athletics — and the opportunity to further explore their individual academic interests with extensive higher level courses. By the time our girls graduate, they're ready to take on whatever comes their way. They are unafraid to raise their hand, let their voices be heard, and make an impact on the world in their own way.

Choose your own adventure.

We know there’s no one way to learn. Every path is different. Our Upper School curriculum empowers students to explore their interests through tailored classes, independent research, and other opportunities to delve deep. Students partner with teachers, advisors, and parents to curate their learning and uncover hidden passions along the way. Students take on classes like Astrophysics, Anatomy and Physiology, Art and Literature, the Third Reich and the Holocaust, Multivariable Calculus and Linear Algebra, Neuroscience, Film as History, and more.

Special Studies Program

SSPs — or Special Studies Programs — are our immersive learning experiences held each year. Freshmen, sophomores, and juniors can choose on-campus options or travel to far-off places to broaden their horizons and ways of thinking. AIS girls have immersed themselves in Cuban language and culture, road-tripped through the South to study the Civil Rights Movement, built homes for Habitat for Humanity, conducted archeological digs on campus, and designed wearable electronics. 

Senior Assembly

By the time senior year rolls around, the art of public speaking is second nature to our students. Senior Assembly is the time when our seniors shine. Each student prepares and presents a 10-minute speech on the topic of her choice, sharing her passion and knowledge with the entire Upper School community.

Senior Seminars

After final exams, seniors take part in Senior Seminars: short, focused classes on thought-provoking topics including neuroscience, French culture, health and wellness, and AIS’s College 101, a frank discussion with young alumnae about what to expect about life on a college campus. 

Self-discovery extends beyond the classroom.

Agnes Irwin girls find their passion by choosing from over 50 student clubs and organizations that focus on everything from wielding the gavel in student government to harmonizing in our a cappella group, the Bel Cantos. And if we don’t have the activity you want, make a pitch for a new one and take the lead. That’s the mark of a true Agnes Irwin girl.

You couldn't ask for better college counselors.

They're veteran college admission officers and master counselors who really get to know our students and help them reach their goals. Education about the college admission process begins in ninth grade and becomes intensive junior year, with seminars, family meetings, and visits from colleges. Seniors participate in weekly seminars, one-on-one meetings, application sessions, and more.
