The Independent School League, also known as the ISL is a league of 16 relatively small New England Prep schools. The ISL has some of the best schools in the United States, most notably The Groton School, Middlesex School, and Roxbury Latin School, among others. The ISL is also well know for its strong athletics, especially in Football, Hockey, and Basketball.
Just because the ISL schools are smaller, doesn't mean they cant hold their own with the larger schools like Pillips Andover, and Chotae.
