The National Service Training Program (NSTP) was established to develop service, nationalism, and patriotism among Filipino youth. It originated from the National Defense Act of 1935 and was later expanded through laws like the National Service Law of 1980. The current NSTP law was passed in 2002 and mandates students to undergo civic welfare, literacy, or Reserve Officer Training Corps. The chapter then discusses the history of NSTP and its components, as well as the constitutional basis. It provides background on Nueva Ecija University of Science and Technology, which was established in 1908 and has evolved into a specialized university.
