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

Notes:

• Class size audits were not conducted in 1998, 1999, 2000 and 2001. Data for other years not included in the factsheet is available through the CSV file below.

• 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.
