In 1964 the entire block north of Santo Domingo was purchased for a new building completed in 1971. The 1972 Nicaragua earthquake devastated the area, but the new school remained intact. Classes opened in 1973 under the new name Instituto Loyola, which now included secondary school, the first Jesuit secondary school in Central America to admit girls. This came about through the reduction of the local population and consequent closing of the night school after the earthquake. In 1979 the school began operating in two shifts: morning elementary and afternoon secondary. The same year the Sandinistas assumed power. State subsidies diminished, and ended in 1993. The school is an active member of ACOSICAM (Association of Schools of the Society of Jesus in Central America) and FLACSI (Latin American Federation of the Society of Jesus).
