Average government primary school class sizes by school size (2009-2024)

The class size audit is conducted in all NSW government primary, infant and central (primary grades only) schools in March each year.

Notes:

Students attending schools for specific purposes (SSPs), students in support classes in regular schools and distance education students are excluded from average class size calculations.
The average class size for each year level is calculated from regular and multi-age classes that contain a student from that year level. This can result in a lower K-6 average class size than any individual year level.
From 2017, school size is based on primary enrolment rather than school classification.
Data from earlier years is not replaced in the Class Size fact sheet. Schools change size. Historical data displays the data that was correct in that year.
Refer to the individual class size factsheet publication for further information and policy context.
