Boarding Houses
The school considers the boarding house as an extension of formal education. Its purpose is not only to provide shelter and food to out-station students, but also to provide opportunity for practical community living. The community life in the boarding house demands certain rules and regulations for the maintenance of discipline and order. Boarding House rules are kept to a minimum, and the students and their parents are expected to respect and obey them strictly.
