Compute the pupil–teacher ratio and compare it against the RTE norms — 30:1 for primary and 35:1 for upper primary — with the number of teachers required at the norm and how many the school is short.
Norms apply to elementary education, are assessed per school, and states differ on how head teachers, part-time and subject staff are counted.
The ratio itself is a division anyone can do. The number a school is actually asked for is the second one: at the applicable norm, how many teachers should be in post, and how many are missing.
Four hundred and twenty students at 30:1 requires fourteen teachers, not thirteen point nine. Reporting the fractional figure and rounding down is the commonest way a school records itself as compliant when it is one teacher short.
Not every employee. Teaching staff count; administrative staff do not. Head teachers, part-time instructors and specialist subject teachers are treated differently under different state rules, and a school counting generously to reach a norm is the version an inspection will disagree with.
Phrased the way they arrive, answered so each one stands on its own.
30:1 for primary and 35:1 for upper primary under the Act’s schedule, assessed per school. States apply additional conditions.
The RTE norms cover elementary education. Secondary and senior secondary norms come from the board and the state, and differ.
Per school. A group averaging across campuses can look compliant while an individual campus is not, which is how the ratio is actually assessed.
