Envisioned as a school that will provide quality and ChristianCatholic educational formation to the young, it formally opened on June 1969 and offered kinder and grade one classes. The SAS educational system was placed under De La Salle supervision, and the impressive result of its first year operation convinced skeptics of the sincerity of its objectives and vision. From 44 pupils and two teachers, and succeeding school years saw the rapid growth of the school both in student environment and hired teachers.After only one year a primary building was built beside the left wing of the church. Then in 1971, construction of another building for the High School classrooms started. It was completed in 1972. The basketball court followed.

She stayed for two years, while Sr. Ma. Leonora served as elementary principal for SY 1972-1973. Then, in 1973-1976, Miss Patrocinio San Juan took over. The year 1975 also saw the retirement of Monsignor Francisco V. Domingo, both as town parish and school director. School Year 1975-1976 ushered in new administration for SAS. Fr. Luciano Paguiligan became the new director. Miss San Juan left, and in 1977, Fr. Corsie Legaspi took over her post. He stayed up to SY 1978-79.
