8/10GreatSchools RatingParent Rating AverageThis school is very unsafe! we had to evacuate from an earthquake that was 40 miles away a few years ago because they thought it would fall down. (Most people didn't even notice the 1 second of slight shaking) 1 star. Cracks in the building too.Student Review8mo ago - Cos Cob School

6/10GreatSchools RatingParent Rating AverageWonderful teachers and safe environment. Good building with plenty of land behind where the kids can play. new Adequate staff ao the school is fairly well resourced. My daughter did very well academically and it has carried forward into Central middle school. Good parental engagement especially when it domes to the annual fund raiser / carnival.
