The School calendar was changed to that of the U.S. school year in 1971 . After being badly damaged in Managua 's 1972 earthquake , the school was moved south of the city to its current location in Lomas de Monserrat . The former site was sold in order to facilitate the purchase of new land . A new elementary school was constructed but ANS lacked sufficient funds to build comparable secondary classrooms . In 1973 the U.S. Government donated prefabricated materials to help ANS build " temporary " trailer style high school classrooms . Building materials were scarce due to the continuing recovery from the earthquake
