Founded by the late Dr. R.P. Singhal - a former CBSE Chairman and World Bank Advisor who received the "Lifelong Contribution to School Education Award" from the Chief Minister of Delhi in April 2007 - Delhi International Public School in Sector 23, Dwarka carries a legacy that few schools in the capital can match. Operating as a co-educational, English-medium CBSE school from Nursery through Class 12, DIS is guided today by Chairman Shri Y.P. Purang, a retired Additional Director of Education with 35 years of service under the Directorate of Education, GNCT Delhi, and Principal Ms. Shruti Sharma. Padmashree Shri Anand Kumar, founder of Super 30, serves as the school's Curriculum Advisor — a distinction that speaks to the institution's commitment to meaningful, outcome-focused learning.

As a CBSE school in Dwarka, DIS published its Class 10 and Class 12 board toppers for the 2025-26 session on its website, reflecting consistent performance at the senior secondary level.
