|Six Schools League|
The Six Schools League (SSL) is an athletic league composed of six New England prep schools. It was founded in 2015 as the Five Schools League by Phillips Exeter Academy, Phillips Academy Andover, Choate Rosemary Hall, Deerfield Academy, and Northfield Mount Hermon School. The league aims to quell aggressive athletic recruiting among member schools, as well as support friendly competition.
