From Herran To Antipolo
After some time, the Herran site was sold as the area was becoming a commercial center and was no longer conducive to learning. In 1972-73, four of the San Lorenzo teachers were transferred to pave the way for merging elementary schools and secondary schools of Herran and San Lorenzo. In 1973-74, the Herran and San Lorenzo schools fused: the High School and the College were based in San Lorenzo while the Preschool and Grade School briefly occupied Herran, then temporarily moved to San Lorenzo in June, 1974. Finally the Grade School settled in Antipolo along Sumulong Highway on September 11, 1974. The Preschool stayed with the High School and College of San Lorenzo. However the distance between Antipolo and Manila became a problem to many parents who wanted Assumption education for their children. The persistent appeal of the alumnae and parents to re-open the elementary level in San Lorenzo was heeded. Grade 1 was re-opened in 1981 and starting school year 1988-89 grade levels were added until the San Lorenzo Grade School graduated its first Grade 7 students in March 1993.
Assumption Antipolo, on the other hand, had its Preschool, to which it added a Kindergarten level in 1984. A High School was opened for First Year in school year 1987-88. The High School completed its four levels and had its first commencement exercises in March 1991.
The Antipolo school site also houses a Center for Service and Sharing (CSS), two Retreat houses for spiritual and social formation, the office of the Philippine Council for Peace and Global Education and PACEM that maintains an Ecology Park. With the completion of the basic education department and the stability of the school as an institution, AA became a corporation on its own in June 1997.
