The first campus was located at the Isthmus of Rosario, in the town of San Roque where Garita Elementary School now stands.

In 1903, Cavite High School transferred to an old but spacious disputed government land where a Spanish hospital stands.

In 1928, the school had to move to Caridad Preparatory before transferring to its present lot, a sprawling 6-hectare lot located donated by Caridad Estate of Cavite, Inc. through Mr. Hammond Buck who was engaged in the Bureau of Education prior to being engaged in real estate.

Back then, Junior and Senior High School students were given the choice whether they preferred vocational, college preparatory or an elective curriculum.

They could choose mechanical repairs, machinery operations, practical electricity, welding, sheetmetal, shipfitter, pipefitter or foundry.

SCIENCE - JHS Clubs: 2002 marked the centenary of Cavite National High Schools' founding.

Two of the oldest alumni of Cavite National High School were also present and were awarded by the President.
