The School Advisory Board (SAB) was formerly known as the Board of Governors. The SAB comprises a minimum of eight elected members including a Chairman who is appointed by the Archbishop of the Diocese. The majority of elected members are practising Catholics who bring to the SAB an expert knowledge-base in a variety of fields such as Law, Education, Accounting, or Construction. A parent from both the Prep and High schools, the Head of School, and members of the Home School Association and Parish Council also sit on the SAB.
As an advisory body meeting at least once a month, the SAB oversees the management decisions of the school. Operating under a set of By Laws, duties include advising the Head of School on matters pertaining to conduct, supervision and the efficient management of the school; approving regulations and appointments; ensuring compliance with the School’s Inspectorate Report and the Education Law of the Cayman Islands; and promoting the total growth and development of students.
