As the governing body of the school, the trustees, in partnership with the head of school, are responsible for providing leadership and a framework within which the faculty members and administration implement the institutional mission.

The Board delegates to the head of school the responsibility for leading the school and designing and implementing the curriculum to meet the goals of the institutional mission and policies. It is the responsibility of the Board to oversee the actions of the head of school in these endeavors.

The Board of Trustees does not intervene in the daily affairs of the school, including curriculum development, hiring, evaluating, or terminating faculty and staff. Instead, the Board focuses on three areas critical to the success of any school:

• Selecting, evaluating, and supporting the head of school, to whom it delegates authority to manage the school
• Developing broad institutional policies that guide the head of school in running the school
• Being accountable for the financial well-being of the school

In the conduct of its official business, the Board acts only as a whole; individual trustees, including the Board chair, have no authority to act unless specifically authorized to do so by the Board acting as a whole. The Board is comprised of various committees, which closely parallel the operational functions of the school. Excluding the Executive Committee, participation on a committee is not restricted to trustees. Some committees include representatives from the faculty, the patron body, and/or the alumni body.
