Canterbury School is a non-profit educational organization with a self-electing Board of Trustees. The board establishes educational objectives and policies, is responsible for the authorization of fiscal decisions, and appoints the headmaster who implements the above and manages the day-to-day operations and business of the school. The Board of Trustees is assisted in its support of the mission of the school by the Canterbury Foundation, whose members are appointed by the school's Board of Trustees, and who manage and direct the school's endowment.
