On June 12, 1950, the late Congressman Luciano Millan of the 5th (now 6th) Congressional District of Pangasinan worked for the enhancement of R.A. 2430 authorizing the appropriation of P200, 000 for the establishment, operation and maintenance of the Eastern Pangasinan National High School (EPNAS) in Sta. Maria, Pangasinan. After six years of operation, EPNAS was converted into a college with the enactment of R.A. 4178 known as the Eastern Pangasinan Agricultural College (EPAC).
 
Offered courses then were Bachelor of Science in Agriculture (BSA) with specializations in Agronomy and Animal Husbandry; and the two-year Associate Agricultural Technology.
 
On June 11,1978 the collegiate programs, some members of the faculty and staff, facilities and equipment, and a number of building were formally and legally integrated to the Pangasinan State University(PSU) system by virtue of PD 1497 in the school year 1979-1980 and thus become PSU-Sta. Maria (PSU-SM). The college offered degrees in Bachelor of Science in Agriculture majors in Animal Husbandry, Crop Science, Agricultural Education, Agriculture Economics and Agricultural Extension.
 
Since it became a component college of the university, PSU-SM was able to realize the construction and installation of more infrastructures: Post Harvest, Capability Building Center, under the leadership of the then University President Reynaldo P. Segui with the political will and commitment of His Excellency Pres. Fidel V. Ramos, Sen. Letecia Ramos-Shahani, Cong. Ranjit R. Shahani and President Assistant Benjamin de Leon.
