The grade school was opened in 1979 with an initial enrolment of 29 pupils. Thenceforth, the school population and school building facilities steadily grew. In 1985, the school opened its High School Department with only 15 students. Four years later, the school graduated its first batch of 19 pioneers at the National Shrine of Our Lady of Fatima with the NCR chief of secondary schools, Dr. Pilar Pascual, as guest of honor. For eight consecutive years, the High School Department took pride in the 100% passing of students in the National Secondary Aptitude Test formerly the National College Entrance Examination. In 1995, the College Department was opened with an enrollment of 50 students. The department initially offered the following degree programs: Bachelor of arts, bachelor of elementary education, bachelor of secondary education, bachelor of science in commerce, bachelor of science in computer and the two–year program, associate in computer technology. To date, the College Department maintains the offering of bachelor's degrees in education, for elementary and high school and bachelor of science in commerce. The rest have been gradually phased out.
