Here she's free.

To discover her voice. Her intellect. And her ability to understand others. Her courage and tenacity are always on display in the classroom, on the playing field, and out in the community.

She has the power.

To learn. To create. To discover and master unfamiliar terrain. She wants to tackle complex real-world problems, find solutions, and grow into a courageous leader who will shape her generation.

At Agnes Irwin

We Empower Girls

To explore, to reach higher, to experience the joy of discovering their very best selves. So by the time our students graduate, they're ready to succeed in whatever paths they choose.


Why All Girls?

Here, she’s free.

To take the lead. Be class president or a math whiz. A record-breaking athlete. The soloist. Or anything else she can imagine.

Here, we don't put girls in a box. We take them outside to get their hands dirty. Watch them tinker in our iWonder Lab maker space and Innovation Center to ignite their curiosity and creativity. Because here, she will be empowered by all that's possible.

Class of 2007, AIS 150th Anniversary Production Manager

AIS taught me how to be bold and unapologetic in my pursuits. I sincerely doubt that I would even be an entrepreneur today without the confidence and sense of open-ended possibility that I got out of my Agnes Irwin education.

Upper School Director

The best part of my job is watching a student have an "aha" moment. I have found that the biggest breakthrough moments come when students are faced with something that really scares them – from belaying off a cliff to failing a test — and realize that they can become stronger as they move through those scary moments.

I like Agnes Irwin because the founder of the school was independent-minded — just like me.

Upper School Science Teacher

In my computer science classes, a number of students have discovered that coding is a passion they hadn't considered before. These students have gone on to major in CS in college. It makes me happy to know that I was able to nurture this new dream.
