School Reviews

Parent of a twelfth grader. We're getting nostalgic already but are so excited for our son who has just been admitted ED to Columbia. Amazingly diverse student body and faculty. Small classes but with a lot of individualized focus on students. Emphasis on student independence which we know will benefit him in NYC next year. I've heard admissions is getting increasingly competitive. We're thankful our son could get it when he did so many years ago!

We've been with ISB for several years now and my daughter is so happy with the program and with her friends. Teachers are amazing, dedicated, well-educated and really care about their students. Love the emphasis on building empathy and valuing the diversity of perspective. She is in middle school now and we plan to stay for the IB program in the upper school.

We've been with ISB for several years now. One child in middle school, the other in upper school. We were previously happy with the school but are even happier now with the recent change in leadership. Our children have thrived at ISB. They come from an English-speaking home, so the opportunity to connect them with another language and with a more globally focused curriculum and internationally diverse student community has been amazing.
