Why is the school system so poorly rated? It seems like such a great place to live?

Graduates from New Rochelle High School have been accepted to Harvard, Yale, Dartmouth, University of Michigan and Chicago, Williams, Amherst as well as Suny Purchase, Iona College and hundreds of other excellent colleges and universities.

Contact the district directly and find out what they have to offer for your children. It is a great place to live.
