Data Notes:
-
Class size audits are conducted by CESE (Centre for Education Statistics and Evaluation) in March each year. Audits were not conducted in 1998, 1999, 2000 and 2001.
-
Data for 2020 should be treated with caution. The collection took place in March when schools were impacted by COVID-19, so fewer data checks were carried out.
-
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 grade is calculated by taking the number of students in all classes that a student from that grade is in (including composite/multi age classes) divided by the total number of classes that includes a student from that grade. This can result in a lower Kindergarten to Year 6 average class size than any individual year level.
-
From 2017, school size is based on primary enrolment rather than school classification.
-
Schools change size, so data in Table 2 is not necessarily comparable to previous iterations in earlier fact sheets.
