Classrooms and offices were made of bamboos and nipa in the “middle of a wilderness.” Funds from FOA-PHILCUSA later came and permanent buildings replaced the bamboo structures. Expansion and development was accelerated when CRHS was converted to Tarlac National Agricultural School (TNAS) in 1957, under a Superintendent. It became a policy to make all projects profitable – piggery, poultry, goat and vegetables. Linkaging for research started from pork barrel funds. In 1961, the two-year technical agriculture post secondary course was opened and in 1963, the Health Center was built out of funds from the Philippine Charity Sweepstakes. By that time, TNAS already had a school hymn and a student publication, “The Carabao.” In 1965, TNAS and Tarlac School of Arts and Trades (TSAT) were merged to become the Tarlac College of Technology. TNAS became TCT-College of Agriculture (TCT-CA) while TSAT became the Tarlac College of Technology – College of Arts and Trades (TCT-CAT) by virtue of RA 4337. As TCT-CA, it offered three degree programs: Bachelor of Science in Elementary Education major in Elementary Agriculture or Home Economics (BSEEd); Bachelor of Science in Agriculture (BSA) major in Crop Science/Animal Science; and Bachelor of Science in Agricultural Engineering (BSAEng’g). Government programs related to agriculture, especially after the declaration of Martial Law in 1972 gave a boost to the enrollment in these courses. Graduates found immediate employment here and abroad. From all indications the school could well become autonomous. Thus, on December 18, 1974 by virtue of PD 609 issued by President Ferdinand E. Marcos, Tarlac College of Agriculture became one of the state colleges in the country. The first College President was Mr. Jose L. Milla. During President Milla's stewardship, the campus area was increased to 60 hectares; a forestry laboratory in Titi Calao, Mayantoc was acquired through PD 1506; Fishery was added to the existing production projects and joint researches with IRRI were undertaken. Enrollment further increased and the number of faculty and non-teaching. The second College President was Robustiano J. Estrada. Upon his assumption, the ten-year development program and the TCA Code were prepared. There was a major reorganization in the administrative set up of the College.
