Welcome to AIS
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.

She's up for the challenge.

To try new things. To take a risk. To take a leap — and take the lead. She’s developing the confidence to forge her own path, set her heights high, and exceed even her own expectations.

She can. She will.

Thrive. Take risks. Fall and get back up again. But stronger and smarter. For nearly 150 years, we've helped our girls understand their power. Then unleash it.



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.
