We recently joined AIS from another top-ranked all-girls private school in the Mainline area and our experience has completely exceeded our expectations! AIS is an incredibly positive and empowering school for my daughters and their academics are absolutely outstanding! Our daughters are thriving and excelling beyond our wildest dreams and they teach the girls how to lead with empathy and kindness. My daughter was bullied mercilessly at her former school, but at AIS they have absolutely no tolerance for bullying or unkind behavior whatsoever. If you are seeking a school that fosters a positive, happy learning environment as well as superior academics, AIS is the school for you.

I have a few daughters at this school and am constantly amazed at the warmth and endless support from the faculty. Each teacher goes above and beyond to help educate my girls in the best way possible to their individual needs and learning styles. I see my girls developing into intelligent, kind, mindful, thoughtful and happy girls. I attribute this development to this amazing school.
