Eulogio "Amang" Rodriguez Institute of Science and Technology (EARIST) was established after the liberation of Manila in 1945.
EARIST traces back its development from that of a vocational high school with only a room at the second floor of the Mapa High School, nine teachers, a clerk, and 147 students under Mr. Pantaleon Regala, its principal.
Its former name was Eulogio Rodriguez Vocational High School (ERVHS).
