Early Childhood Education and Elementary courses were initially offered. In 1940, three special vocational courses were opened: typing, stenography, and dressmaking. The outbreak of World War II forced the closure of the school. However, upon the insistence of the Japanese occupation forces, the school re-opened and secondary courses were offered. The operation of the school was again temporarily halted with the arrival of the American liberation forces in 1945. The school reopened later that year, with new college courses added to the school's curriculum.
