In order to promote sports, games and co-curricular activities in an atmosphere of fine sportsmanship as well as excellent competitive spirit, the students of IVWS are divided into 4 houses namely GANGA, BRAMHAPUTRA, INDUS and YAMUNA. Each house is guided by two teachers (mentors), a house captain and vice-captain. The houses have their separate uniforms and house flags. Different inter-house competitions are held all through the year and all the competitions climax to the Annual Sports meet.
