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).

Lists are ordered by size, pupil–teacher ratio, growth, founding year or name, each of which describes the school rather than its outcomes.
