The pastor is the ex officio chief administrative officer of the parish school.  He implements the policies of the Catholic School Board of the Archdiocese of Los Angeles.  On points not covered by Archdiocesan policy, he determines policies consistent with Archdiocesan policy and appropriate to the needs of the school.  The pastor has administrative, personnel, finance, and spiritual responsibilities in relation to the school.

The principal, as delegate of the pastor, has immediate responsibility for implementing the philosophy of the school in its regular operation.  The principal administers the entire school program; supervises the staff and instructional program; and relates with the parents, the parish, and the general public.

The role of the vice-principals is to assist the principal in fulfilling the principal's many responsibilities.  The vice-principals act as a consultant to the principal and carry out any duties specified by the principal.

The faculty supports and implements the philosophy of Catholic education.  They give evidence of lived Gospel values and participate in building the faith community.  The teachers utilize an instructional process that includes planning and evaluation, through the incorporation of the Core Instructional Practices.  They work cooperatively with the administration, educational staff, support personnel, parents, and students.  In addition to teaching duties, teachers assume co-curricular responsibilities as specified by the administration.

The support staff includes classroom assistants, school office manager, custodians, and after school care staff.  The support staff enhances teacher effectiveness, improves student learning, and accomplishes the non-teaching tasks necessary for the school's operation.  They are under the immediate supervision and direction of the principal, vice-principals, and/or classroom teachers.​
