The ultimate responsibility for the governance of Cathedral School for Boys resides with the Board of Trustees
, whose twenty-five members bring a diversity of talent and broad practical and professional experience assuring the School's present stability, its development, and its perpetuation. The Trustees are responsible for formulating policy and for establishing and maintaining the sound financial condition of the school. The Board appoints the Headmaster, who as chief executive officer directs all day-to-day activities and operations necessary for the accomplishments of the school's program, the appointment of faculty and staff members, maintenance of educational and behavioral standards, and administration of the operating budget.
Cathedral School is a financially independent department of Grace Cathedral Corporation. The Cathedral Board provides two trustees, approves new trustees, approves changes in the by-laws, but does not initiate policy. The Bishop approves the appointment of the Headmaster and nominates him or her as a senior staff member of the Cathedral with the title of Canon Headmaster. The Dean is an ex-officio member of the Board and of all Board committees. The Cathedral, School and Diocese share facilities on the Close and contribute to their upkeep on an equitable basis.
Cathedral School for Boys also has an active Parents Association
and Alumni Association which support the school's programs through volunteerism and a variety of community-focused events.
