In 1946, immediately after the war, Tarlac Trade School was officially separated from the Tarlac High School, with the appointment of Manuel T. Espinosa as its principal. More than a decade later, in 1959, the Congress of the Philippines approved House Bill 1006, jointly sponsored by Congressmen Constancio Castaneda and Jose Roy, converting Tarlac Trade School into Tarlac School of Arts and Trades (TSAT); with Mr. Espinosa also becoming its first Superintendent. As a nationalized academic institution, TSAT began to Offer collegiate technical education courses in the province.
