Frequently asked questions
What is the best largest school in Chennai?
Chettinad Vidyashram in Chennai, Tamil Nadu ranks first among largest schools in Chennai with Students 7,176 (Students: 7,176).
How are largest schools in Chennai ranked?
CBSE schools with the highest enrolment reported to UDISE+. Figures are the most recent published by the national authority and matched to the school directory.
Are these 2026 rankings official?
No. They are computed by Success Tutoring from official Indian data (CBSE SARAS – list of affiliated schools; UDISE+ Know Your School – school report cards and state statistics). Nothing on this site ranks Indian schools by results, because no board or ministry publishes school-level results. Lists are ordered by size, pupil–teacher ratio, growth, founding year or name, each of which describes the school rather than its outcomes.
