Gulod came to be known by that name because of its topographical situation. Being situated on an elevated piece of land the central part of the barrio resembles that of the back of an animal with its two sides sloping downward ending into a creek on both sides.

Formerly Gulod-Labac was a part of Gulod-Itaas under one Pangulo and with an engkargado who represented his sitio and who looked after the improvement, peace and order of his sitio.

Gulod Elementary School's first organized class was housed under the dwelling of the late Miss Agripina Deleniana - 1946 with an enrollment of 50 pupils. Later on, the P.T.A. raised funds through voluntary contributions of the barrio people and aid from the Mayor, the late Mr. Roman Perez. Then the P.T.A. building was put up on the lot borrowed from Mr. and Mrs. Martin Magadia and heirs by the barrio people, free labor under the auspices of the teniente del barrio, Mr. Silvino Cantre. It housed two classes under two teachers. But unfortunately this building was constructed. During the term of Congressman Babao he appropriated Php5,000 for the construction of a standard school building which was put up on the lot of Feliciano and Ines Magadia (brother and sister). This lot was later on acquired by the barrio through expropriation proceedings which was shouldered by the voluntary contributions of the barrio and aid from the municipal council sponsored by Mayor Tolentino. 

In 2023, Gulod Elementary School officially transitioned to Gulod Integrated School under Special Order no. A.4-07-007, s. 2023 following the establishment of its Junior High School program, which began with the opening of Grade 7 which made the school the First Public Integrated Elementary and Junior High school in Batangas City. This milestone marked a significant development in the school’s journey, expanding its educational services beyond elementary education. 

At present, Gulod Integrated School proudly caters to learners from Kindergarten to Grade 9, continuing its commitment to provide inclusive, progressive, and quality education for all.
