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