The main function of NAST is divided into three components, namely, Recognition, Advisory, and Scientific Linkages.
Through its advisory activities, NAST has been able to bring science and technology closer to the lives of the Filipino. Its series of information fora and roundtable discussions have encouraged public participation in open discussions of important and pressing issues in science and technology on a wide range of topics such as biotechnology, genetic engineering, intellectual property rights, information and communications technology, high performance computing, sustainable agriculture and waste management, water resource management among others. Academicians and other local and foreign experts have put their knowledge and expertise together to advise the legislators and the senate, including other policy making bodies of the government and non-government entities, on policies related to science and technology.
As the government's highest recognition body on science and technology, the Academy continues its primary mandate of giving awards to Filipino scientists and scientific and technological endeavors aimed at advancing the state of Philippine science and technology. Moreover, through the NAST, the government is extending its all-out support to Filipino scientists and recognition of their significant contributions to science by providing them with meaningful incentives for the furtherance of their works and to encourage the younger generation to pursue careers in advanced scientific studies and researches.
As early as 1978, the Academy started forging international and national scientific linkages with other science, engineering and technology academes and other similar organizations. NAST's commitment to international and national linkages are aimed at: (1) promoting collaborative efforts among Filipino scientists and between Filipino and Foreign scientists; (2) promoting and encouraging scientific cooperation through Scientists Exchange Visit Program under the memorandum of agreement between NAST and a foreign science academy; (3) endorsing participation in international conferences, meetings, fora, seminars, workshops and similar scientific activities; and (4) publishing and exchanging scientific literature.
