The Board of Trustees

The Board of Trustees is responsible for establishing broad policy goals that align the operation of the school with its mission, providing fiduciary oversight of the school’s operations, and supporting long-range strategic planning to ensure Potomac’s future.

The Board is comprised of between 17 and 26 members. It strives to reflect diversity consistent with the stated mission of the School. Its members include alumni, current parents, past parents, grandparents and individuals from the broader community who bring particular expertise and perspective.

Members may serve two three-year terms. Requests for trustee nominations to fill Board vacancies are made each fall to the parent, faculty, and alumni communities. The Committee on Trustees then selects its candidates based on a set of specific criteria and presents a slate to the full Board for election in the spring.

Committees of the Board of Trustees currently include the Executive, Finance, Investment, Audit, Development, Master Plan/Buildings and Grounds, and Committee on Trustees. In any given year task forces may be created to address other strategic issues. Officers of the Board are nominated by the Chair of the Board and are elected by the full Board each year.
