The Episcopal Diocese of Florida operated a boys' home on the site from 1921, but this closed in 1953 due to financial problems.

The board is responsible for establishing school policy, managing assets, and selecting a head of school. The dean of St. John's Cathedral is vice-chair and the clergy member of the board.
