The school became independent from the local Parish school in 1956. In 1956, the only building in the school was a Victorian-style mansion named Gadsden. Today, the Gadsden holds the main reception, the student reception, a few offices, and other things. As soon as it became independent from the Parish school, it started accepting both genders. By then, most of the school was relocated to A Block, which had 3 floors.
