The NSS Unit undertakes campus Cleaning, maintaining vermi-compost pit, visiting A.I.D.S Centre, organizing various competitions on festivals and awareness of social issues. A voluntary 7 days NSS live-in camp a one day special camp are some of the main features. The national service scheme with its motto "NOT ME BUT YOU" upholds the need for selfness, service and appreciation of others persons point of view and also to show consideration for fellow human beings. At "C.H.S.S" the N.S.S motto is put into practice and students learn the importance of human values through community service.
