RTE Act, 2009 mandates ______ Pupil-Teacher ratio at Primary Level.

Concept: The Right to Education (RTE) Act, 2009 lays down minimum Pupil-Teacher Ratio (PTR) norms in its Schedule for different schooling stages, so every child gets an adequate share of teaching attention; the standard, most commonly cited figures are 30 : 1 for the Primary stage and 35 : 1 for the Upper Primary stage.

Application: For the Primary stage (Classes I to V), the standard Pupil-Teacher Ratio mandated under the Act is 30 : 1 — one teacher for every 30 students. (For the Upper Primary stage, Classes VI to VIII, the standard figure is 35 : 1.)

Cross-check by value:

• 25 : 1 is stricter than the Act's standard Primary-stage figure of 30 : 1.

• 35 : 1 is the standard ratio quoted for the Upper Primary stage (Classes VI to VIII), a different stage from the one asked about here.

• 40 : 1 is looser than the Act's standard Primary-stage figure of 30 : 1.

This 30 : 1 figure is the ratio consistently confirmed as the Primary-level norm across official answer keys for this question and government summaries of the RTE Act's Schedule.

Note: the Schedule also permits a Pupil-Teacher Ratio of up to 40 : 1 (excluding the head teacher) specifically for Primary schools with enrolment above 200 children; but 30 : 1 remains the figure conventionally tested as the RTE-mandated Primary-level PTR, and it is the option marked correct in official answer keys for this exact question.
