CPS’ history dates back to 1951 when several families relocated to Puerto Rico to work with the Economic Development Administration (Fomento).

They began looking for physical facilities and studying the requirements to create an English school that would fulfill their need for education.

In 1964, Commonwealth Middle and High School was at capacity and grades kindergarten through twelfth needed more classrooms to accommodate all students.

In 1979, the board of directors voted to sell San Juan by the Sea and improve facilities at Parkville and Commonwealth Campuses.
