Co-ed independent day school in Boston's Back Bay for academically adventurous students in grades 9–12

Athletics Overview and Requirements

Athletics can provide a student with a sense of pride and accomplishment through the hard work and competitive spirit that the athletic arena provides. Athletics enhance the overall educational experience and build well-rounded students and leaders. Integrity, fairness and respect—these are the principles of good sportsmanship. With them, the spirit of competition thrives, fueled by honest rivalry, courteous relations, and graceful acceptance of the results.

As such, athletics are an important—and required—part of the overall educational experience at Commonwealth.

Questions may be directed to Director of Athletics, Jackson Elliott '10.
