School Reviews

It's hard to describe the difference in our son's attitude to school, to learning, and just about everything else since starting at September School. He's now learning Spanish at an AP level where he once floundered in incomplete assignments. He's interested in and informed about world events; social studies hadn't even sparked an interest in the past. In areas where he still struggles, he has teachers who understand how he learns and help him along while still holding him to him to high standards. He's actually learning, not just showing up and turning in busywork.Earlier struggles at school extended to his social and emotional life. It was hard to see him struggle when I knew him to be bright, funny, insightful, and kind. September school has drawn that out. He's part of a supportive community, has good friends, and is valued for being himself.
