The main aim of the NSS is to provide hands-on experience to young students in delivering community service. Since its inception in 1969, the number of students of various universities, colleges, and Institutions of higher learning, who volunteered to take part in various community service programs has increased from 40,000 to over 3.8 million by the end of March 2018. SIMAT believes in the spirit of community service and the idea of caring for the welfare of society that is critical for the ultimate well-being of the individual. The NSS, with a technical Cell Unit (No: 233) in the campus embodies these principles and through its activities helps us in serving the community. The program aims to instill the idea of social welfare in students and to provide service to society without bias. NSS volunteers work to ensure that everyone who is needy gets help to enhance their standard of living and lead a life of dignity, thereby learning from people in villages how to lead a good life despite a scarcity of resources. NSS also provides help during natural and man-made disasters by providing food, clothing and first aid to the disaster victims. There are two types of activities: Regular Activities (120 hours) and Annual Special Camp (7 days). All the NSS Volunteers who have served NSS for at least 2 years and have performed 240 hours of work under NSS are entitled to a certificate from the university under the signature of the Vice-Chancellor and the Programme Coordinator. Annual camps, known as Special Camps are held usually located in a rural village or a city suburb and are funded by the government of India. Volunteers are involved in activities like:
