An important characteristic of Groton that has its roots deep in the School's history is the assumption that there is good education to be derived from playing sports. The collaboration and cooperation demanded by team sports, the growth and development that stems from testing athletic talents and skills directly against those of others, and the development of personal character forged in competitive games has always been part of Groton athletics. More recently, individual sports have also brought to students at the School the opportunity to set personal goals and to test themselves against them. Hence, the athletic program strives to develop every student's physical capabilities and to develop such qualities as courage, confidence, self-discipline and sportsmanship. Groton's philosophy is based on developing younger athletes into varsity positions.
All students participate regularly in some form of afternoon exercise.
Teams are selected so that students play with and against others of approximately the same size, age and experience. The program teaches specific skills needed for improved team and individual performance. Students are encouraged to begin sports that are new to them as well as to continue those they have played before coming to Groton.
