The House System is an integral and vibrant part of the school culture. At DPSSL the House System aims to give students an  identity and sense of pride in a supportive and secure environment.The Houses provide for positive competitive spirit and builds a good rapport between students and teachers. There are six Houses in the Junior and Senior school each. Every student is allotted a House at the time of admission.

 House Coordinators and House Wardens shoulder the responsibility for planning and conducting various House Competitions along with the House teachers. Points are awarded to the students throughout the year for their performance. At the end of  the year the prestigious Best House Trophy is awarded to the House that secures the maximum points.
