The Board of Trustees manages the affairs of the school and are responsible for the long-range financial stability of St. James. Board members are elected from nominees submitted by the Board and the Committee on Trustees. Each trustee serves a three-year term and may not serve more than two consecutive three-year terms until the passage of at least one year. The Board must have no fewer than nine, and no more than 15 members, and at least half of the members must be communicants of the Episcopal Church. No one may serve on the Board of Trustees if any employee of the school is an immediate family member.
