Average government primary school class sizes by year (1997, 2002-2025)

Data Notes <ul> <li> 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. </li> <li> 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. </li> <li> 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. </li> <li> 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. </li> <li> From 2017, school size is based on primary enrolment rather than school classification. </li> <li> Schools change size, so data in Table 2 is not necessarily comparable to previous iterations in earlier fact sheets. </li> </ul> Data Source Education Statistics and Measurement, Centre for Education Statistics and Evaluation.
