Founded in 1983 in Dyal Singh Colony, Karnal, Dyal Singh Public School carries the legacy of Sardar Dyal Singh Majithia - a 19th-century nationalist and philanthropist who bequeathed his entire estate to establish institutions of liberal education across northern India. The school is one of four institutions run by the Dyal Singh College Trust Society, which also established Dyal Singh College at Karnal in 1949. What began with around 200 students in 1983 has grown into a senior secondary institution with over 2,000 students currently enrolled, making it among the recognized CBSE schools in Karnal for families seeking continuous schooling from Nursery through Class 12.

Affiliated with the Central Board of Secondary Education, the school offers all major streams at the senior secondary level - Medical, Non-Medical, Commerce, and Humanities -giving students flexibility in choosing their academic direction after Class 10. Results for Class 10 and Class 12 are published on the school's official website each session, and the school has maintained a consistent record of board performance over the years. The teaching staff is organized across PGTS, TGT, PRT, and PPRT categories, and an active NCC Army Wing adds a structured discipline and leadership track for interested students.

Spread across approximately three acres in Dyal Singh Colony, the campus has a U-shaped building with well-ventilated, spacious classrooms and seven dedicated laboratories - Biology, Chemistry, Physics, Computer, Mathematics, Geography, and Psychology. A library, Art and Craft room, and a playground supporting Volleyball, Kho-Kho, Basketball, Badminton, and Cricket complete the campus setup. Student clubs including the Eco Club, Science Club, Literary Club, Social Service Club, and Health & Wellness Club run alongside the academic calendar, and the school also maintains an active alumni network.
