The Choir School operates under the auspices of the Roman Catholic Archdiocese of Boston and is located at Saint Paul Parish in Cambridge. The school is run by its headmaster in conjunction with the music director, but final authority on all issues lies with the pastor of Saint Paul Church. See the list of Administrators.

The school’s advisory board consists of thirteen individuals from a variety of professions who assist the pastor and headmaster in fulfilling the mission of the school. Although the advisory board has no fiduciary responsibility or authority, it functions as a working board, taking on special projects to ensure the school’s growth and viability.
