Curtis is governed by a self-perpetuating Board of Trustees. Historically, the Board has been comprised of parents, past parents, alumni and friends of the school, with the majority of trustees being current parents. The Board establishes policy and works closely with the Headmaster and administration to see to it that these policies are implemented. New trustees are elected by the Board and serve for a three-year term, renewable twice.
Standing committees of the Board include Academic Affairs, Buildings and Grounds, Development, Diversity and Multiculturalism, Finance, Long Range Planning and Trusteeship. From time to time, the Board creates ad hoc and/or special committees to make recommendations to the full board. In all cases, unless otherwise specifically authorized, final policy approval rests with the full Board. Administrators, faculty members and parents may be invited to serve on committees at the pleasure of the Board Chair and the Headmaster. The Headmaster, Chief Operating and Financial Officer, President of the Parents Association and other administrators may attend Board meetings but are ex-officio.
