The Lasam Academy Incorporated stated as a branch of the Northern Philippines Academy of Gattara, Cagayan, a secondary institution under the operation and control of the United Methodist Church of Gattaran. The idea of opening a branch at the newly established Municipality of Lasam (formerly Barrio Macatabang of Gattaran) was conceptualized by the school principal, Atty. Florencio Castillo, one of the prominent businessmen at the time. Then, when Atty. Castillo was able to negotiate a one-hectare lot from the late Basilio Oao Medrano, the school buildings were finally built and the Lasam Academy was finally established.

           The Department of Education issued a government permit #329 on May 10, 1951 recognizing the Lasam Academy as legitimate Secondary Educational Institution, separate and distinct from the Northern Philippines Academy. Then on January 03, 1958, the Securities and Exchange Commission issued SEC Registration #313423 recognizing the Lasam Academy as non-sectarian, stock, educational institution with seven (7) original stakeholders.

              In 1989, after thirty-eight years of operation, the founder and major stockholder, Atty. Florencio Castillo planned to close the school. His major reasons were due to the unstable peace and order situation in Lasam and that the school was no longer profitable to operate due to increasing cost of operation and competition from other schools, which were also opened and established in Lasam. The Medrano clan, however, after series of consultations with Dr. Charlie M. Go, a medical doctor practitioner and successful businessman, decided to save the school. They could not allow the Lasam Academy to sink into oblivion so, with the help of their friends, relatives and acquaintances; they bought the shares of Atty. Florencio amounting to Php 300,000.00.

               On its 71st years of existence, through thick and thin, it is indeed that Lasam Academy Incorporated is firmly adhering to its vocation as a molder of young and brilliant minds. Thus, the academe has always been recognized whether academic, sports or socio-cultural endeavours. It continues to build, link and connect to the needs of its stockholders and to the demands of this challenging world. On August 28, 2015, the Department of Education granted the Lasam Academy Incorporated its permit to operate Senior High School with permit #S-087, s.2015. Hence, this School Year 2022 – 2023 we would be offering Humanities and Social Sciences Strand. On November 16, 2017, the Department of Education recognized the school with Government Recognition No. J-21, s. 2017 to continue its philosophy, vision, mission, goal and objectives towards excellence.
