Holistic education is the maxim that NSS upholds and promotes. Mental and physical development of the child is aptly developed and nurtured by organising the Sports Day. Track and field events, team games, gymnastics, yoga and drills are the events that students participate in and perform to the best of their ability. Adrenalin runs high as each participant strives hard to win points for their House so as to lift the Champion House Trophy. The competitive spirit between the Houses on the sports field is intense and aggressive. Over the years, the theme of drills have changed to cause-oriented displays involving a huge number of students. March past by the four houses, parade by the NCC cadets and the Scouts and Guide Contigents are the highlights of the Sports Day. The sports day includes events organised for parents, teachers, alumni and helpers of the school are enjoyed by one and all.
