On June 1947, almost a year after Rafael Palma College was founded; the High School Department came into existence.She opened her doors to more than 1000 students from first to fourth year levels. The principal, Mrs. Romana O. Manalo, was assigned to office with a complete teaching force of 10 devoted teachers.
The high school population was housed in an eight-room structure then known as Gallares building located near the wharf. Today,the High School is recognized to provide quality education in the secondary level through the development of the trinity of virtues - scholarship, character and service.
