The College of Agriculture in Infanta, Pangasinan was created by PD 1494 signed by President Marcos on June 11, 1978. On the same day, PD 1497 was signed by the President, establishing the Pangasinan State University (PSU) which integrated the college level courses of six state-funded institutions in Pangasinan, the College of Agriculture in Infanta was integrated as the seventh. PSU became officially operational on July 1, 1979 but the College of Agriculture in Infanta started its operation on June 1981 and earned its autonomous status in January 1983.

In August 16, 1978, President Marcos proclaimed the 1000 hectares in Barangay Bamban, Infanta for the College (Proclamation No. 1771 series of 1978). Concerned leaders of Pangasinan helped in the preparations, among whom are: Hon. Jacobo C. Clave, Vice Governor of Pangasinan (Formerly Presidential Executive Assistant), Governor Aguedo F. Agbayani and the members of the Sangguniang Panlalawigan; the Honorable Assemblymen of Pangasinan; Mayor Cesar Vallarta and the members of the Sangguniang Bayan of Infanta, including the Barangay Officials of Bamban and nearby barangays.

Director Benjamin Mercado of the Ministry of Budget, Region I and his staff with PSU officials visited the site in early 1980 and recommended (and finally approved) the construction in CY 1981 of one Administration Building, Farm Machinery Building, and Agricultural Building and a water tank to start the educational institution in Western Pangasinan and nearby Zambales to serve the educational needs of the youth.

The College of Agriculture inย Infanta has a wide agricultural and forest reserves which serve as training ground for the students and all agencies committed to development. It is about 7.5 Km. from the town proper and located near San Felipe River, the National Irrigation Administration (NIA) dam, and the white clay mines.

While the buildings and the roads are under construction, the college holds its classes in some of the rooms in the elementary schools in Infanta town on arrangement with the provincial schools Superintendent and MEC Officials.

During the School Year 1989-1990, the Agricultural Education Outreach Project (AEOP) Student Village Training Center (SVTC) was implemented in cooperation with the DECS thus bolstering the collegeโ€™s quest for relevance.ย  PSU Infanta shifts its offering to a more intensive program-the BSA, major in Farming Systems, a special ladderized course for poor but deserving students from the province of Pangasinan.

PSU Infanta started with curricular offerings such as the Bachelor of Science in Agriculture with majors in Crop Science and Animal Science, the Bachelor of Science in Agricultural Technology (Integrated Elementary and High School), and the two year Associate in Agricultural Technology together with the four year Secondary Level (High School) oriented towards vocational agriculture
