From charity money and donation, Fr. Tajon was able to maintain the school free of tuition fee but with regularly paid teachers. He indeed established a feat of sort, as he was able to have this arrangement even during the duration of the Second World War. Enrolment increased each year up to 1944. The pupils were housed in three classrooms made of nipa and wood. Before Filipino became a national language, it was already part already part of the curriculum though the students spoke English just as well. The school produced most of the leading Catholics in Cainta.
