Enter enrolment and teachers in position for primary, upper primary and secondary to see each level’s pupil-teacher ratio, the norm it is measured against and how many teachers are short or surplus, for one school or a whole block.
For each level the checker uses three numbers: children enrolled (N), teachers in position (T) and the norm. Head teachers are left out of T, as the RTE Schedule does for larger schools.
Ceil rounds up, because a school cannot appoint part of a teacher. The slabs and the 35 : 1 upper primary norm are in the Schedule to the RTE Act, 2009, which also requires a head teacher, in addition, where a primary section has more than 150 children. The Ministry’s 2017 release on student-teacher ratio summarises the Schedule as 30 : 1 at primary and 35 : 1 at upper primary, and gives 30 : 1 at secondary under the RMSA framework. The slab works out to 30 : 1 up to 120 children and allows more children per teacher above that, so a primary PTR above 30 : 1 can still meet the Schedule. Illustrative; confirm with the official source.
A block check covers 12 schools with 1,380 children and 42 teachers at primary, 1,610 children and 41 teachers at upper primary, and 900 children and 34 teachers at secondary.
These figures are made up to show the arithmetic. A block total can meet the norm while individual schools do not: one school with 100 primary children and two teachers (50 : 1) and another with 50 children and four teachers average 150 ÷ 6 = 25 : 1. Run the check school by school, or at least for the schools with the highest enrolment, before deciding where posts should go.
The RTE Act sets the national floor for Classes I–VIII, but states notify their own rules, sanction posts and may count teachers by class, section or school. The Supreme Court has agreed to examine whether one state’s ratio rules are consistent with the Schedule, tagged with an older pending matter on how the Schedule should be read, so interpretation may change. Treat this checker as a first screen, not a ruling on compliance; confirm with your state’s RTE rules and the official source.
A ratio worked out once a year from returns says little about which classrooms are without a teacher this week. A school monitoring dashboard such as EduWatch tracks teacher attendance and the class log in the same record as student attendance, and teacher absence appears on the state’s red list of decisions, so officers see every school on one screen. To decide which schools to visit first, read how to prioritise school inspection visits; for learners already missing days, see the dropout early warning playbook.
Divide the number of children enrolled at a level by the number of teachers in position at that level, leaving out the head teacher. 190 children and 5 teachers at primary is a PTR of 38 : 1.
The Ministry summarises the RTE Schedule as 30 : 1 at primary and 35 : 1 at upper primary; the RMSA framework uses 30 : 1 at secondary. At primary the Schedule itself sets posts in slabs: 2 teachers up to 60 children, 3 up to 90, 4 up to 120, 5 up to 200, and a PTR of no more than 40, excluding the head teacher, above 200. Confirm with the Act’s Schedule and your state’s rules.
At primary, follow the slab: 2 up to 60 children, 3 up to 90, 4 up to 120, 5 up to 200, then ceil(enrolment ÷ 40), plus a head teacher above 150 children. At upper primary, at least three (one each for science and mathematics, social studies and languages) and ceil(enrolment ÷ 35). Illustrative; confirm with the official source.
Because an average hides distribution: a crowded school and an over-staffed one can average to a compliant figure. Check school by school before moving posts.
