What people are saying

by a student
Thursday, April 28, 2016

It has been 7 years since I graduated Chatsworth, and I still have nothing but positive things to say about it!

Very Diverse : Given the number of parents with careers that have a high demand for travel, a fair share of the student body is international. It can be hard when friends move away, but it is also very cool having friends all over the world!

Education: 10/10. The majority of teachers at Chatsworth have attended prestigious universities, provided this, they completely over-prepared me for middle school.

Surrounding Area: Great! a lot of activities for kids. Sports are very big in Larchmont, and almost all kids are involved. Soccer, Lacrosse, Basketball, Sailing and baseball are to name a few. There are also great beaches in the Manor (great for kids as well as adults).

Warning: There are some cliquey parents who grew up in Larchmont and won't move outside their friend group (and their children typically associate with one another), so don't take it personal if you are moving here as an international student/parent, they do it to everyone! Close Quote
