School Reviews

We joined the International School in 2012, when our son was just four years old. One of the main reasons we chose this school was the impression left by the confident, self-assured, kind, and worldly students who spoke at the open house we attended. We wanted those qualities for our son, and we're proud to say that as an eleventh grader, he embodies them all. The school truly shapes children into global citizens. Like others have mentioned, we are not a French-speaking family, but that hasn't stopped our son from becoming fluent in French.
