The National Service Scheme (NSS) is a government-sponsored public service program in India, launched in 1969 by the Ministry of Youth Affairs and Sports. It aims to develop students' personality through community service and social responsibility. NSS provides young volunteers, primarily college and university students, with opportunities to engage in activities that promote social welfare, national integration, and community development.

The core philosophy of NSS is "Not Me, But You," emphasizing selfless service and teamwork. Volunteers participate in various activities such as environmental conservation, health and hygiene awareness, literacy programs, disaster relief, and rural development. Through these initiatives, NSS fosters leadership qualities, discipline, and a sense of duty toward society.

With its motto of "Service Before Self," NSS plays a vital role in shaping responsible citizens who contribute positively to the nation.
