The National Service Training Program (NSTP) was implemented by the University of the Philippines (UP) Diliman in accordance with the Republic Act (RA) 9163, an Act Establishing The National Service Training Program (NSTP) for Tertiary Level Students, enabling the government to create a program that will encourage the youth to actively participate in civic welfare and literacy initiatives as well as defend the country in times of war. It was, however, only in 2011 that UP Diliman paid attention to unifying the different NSTP initiatives of the various colleges and units, after the creation of the Office of the Director of NSTP (system level) and the appointment of an NSTP Coordinator for UP Diliman.
The NSTP Diliman was officially established by virtue of a decision made by the Board of Regents during its 1288th BOR Meeting on June 20, 2013. Its functions are to administer, manage, and coordinate all NSTP offerings and activities in UP Diliman in accordance with RA 9163 of 2001 and its duly approved implementing rules and regulations.
In 2016, following a reorganization of the Office of the Vice Chancellor for Academic Affairs, the NSTP Diliman was created to be headed by a director and a deputy director for National Service Reserve Corps (NSRC).
