10/10GreatSchools RatingParent Rating AverageTerrible experience here. Constantly made fun of and picked on by students and teachers treated me like a total idiot. Went from being respected by peers and teachers at my old school to ridiculed and laughed at by the entire class.Other Review2mo ago - Manhattan Middle School Of The Arts And Academics

5/10GreatSchools RatingParent Rating AverageThis is our first year at Manhattan and we are incredibly pleased with the middle school experience our son is having. When we first moved to the neighborhood (when the school was under old leadership) we were warned to look elsewhere because of some institutional issues. By the time enrollment came around last year, the new principal had infused the school with incredible energy and he was adamant it was his top choice. It feels like a vibrant place where the whole community is striving to improve and make it the best three years possible for every kid there. The principal shared that test scores showed 22% growth last year, which is pretty mind-blowing! I'm always a fan of a place that is focused on growth and improvement rather than one that's resting on its reputation and we've definitely found that at Manhattan.Parent Review6mo ago - Creekside Elementary School At Martin Park
