The Laguna Institute (L.I.) formally opened in June 1930 with 95 students in the first and second year high school. The original L.I. was an old, 2-storey, green and white house, which stood on a 500-square meter lot in the still unpaved Burgos Street. In 1933, it was fully recognized by the Department of Public Institutions as a duly accredited high school.
L.I. was closed until 1945 due to World War II. In 1950, L.I. inaugurated its elementary and college departments. The tertiary level courses offered were Associate in Commercial Science, Elementary Teacher’s Certificate, and Associate in Arts.
