Together with the Principal, the School Board is responsible for ensuring that the religious and educational philosophy of the Institute of the Blessed Virgin Mary (IBVM) is maintained and promoted within the school.

The IBVM appoints members of the Board for an initial term of three years which is renewable and may include members of the Institute, past students, current or past parents, and others independent of the school. The Directors represent a broad mix of skills necessary for the governance of Loreto Nedlands in the areas of education, law, risk, finance, and planning and development.
