Board of Trustees
Volunteers fill all Catlin Gabel board positions. Trustees are carefully selected based on demonstrated service and clear commitment to the school's goals and philosophies.
Potential trustees are nominated by the committee on trustees and elected by the board. The elected board of trustees and several ex-officio board members set policy for the school and review the school's implementation of its policies.
Catlin Gabel School conducts an annual audit of its financials by an outside firm. We also share information on our annual operating budget every year with parents and guardians. Audited financials and the operation budget are on file in the school’s business office and are available for review and discussion by school community members. Please contact the Business Office if you are interested.
