In all sports at Brooks, coaches seek to instill a healthy spirit of competition, to win gracefully and to lose with dignity, and to teach sound skills and to share a love of the sport for its own sake. The main thrust of the athletic program is to encourage physical fitness and team building.
Most sports offer at least two and often three levels of competition.
Brooks competes mainly in the ISL with fifteen other schools, including Groton, Middlesex, Milton and St. Paul's.
