Average government primary school class sizes by year (1997, 2004-2024)

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 1997, 2002 to 2003 and 2011 to 2018 is available on request.

  • 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.
