Located in Chharba, Sahaspur, on the outskirts of Dehradun, Defence Public School was founded in 2015 by the Smt. Subhaga Devi Smriti Education Foundation. The founder set out to address a real gap in the area - families from the hill regions of Uttarakhand and Himachal Pradesh who had settled around Sahaspur and adjoining rural and semi-urban localities had long struggled to find a school nearby that could offer their children a structured, quality education. Defence Public School was built specifically to serve this community, positioning itself as a CBSE school in Dehradun for families in and around Chharba and Sahaspur.

The school follows the CBSE curriculum and is affiliated with the Central Board of Secondary Education, offering classes from Nursery through Class 12. Chairman Neelkanth Bhatt has spoken of the school's approach to education as treating "every child as a genius," with classroom teaching structured around consistent academic engagement rather than rote learning alone. The management has worked to keep teaching practices aligned with current trends, aiming to give students in this part of Dehradun access to the kind of schooling typically concentrated in the city centre.

The campus includes computer labs equipped with interactive Activ Boards (Promethean boards), a library, and tutorial rooms for general teaching. Additional facilities cover transportation, healthcare support, books and stationery arrangements, and campus security. The use of interactive boards in classroom delivery is a feature the school highlights as part of its day-to-day teaching method, helping bring a more technology-integrated approach to a semi-rural setting.

Admissions at Defence Public School are currently open, with both online registration and a downloadable admission form available through the school's official website. Parents can reach the school at +91 135-6508010, 9761731234, or 09536888010, or via email at info@defencepublicschool.net.
