Data notes <ul> <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 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. </li> <li> From 2017, school size is based on primary enrolment rather than school classification. </li> <li> 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. </li> <li> Refer to the individual class size factsheet publication for further information and policy context. </li> </ul> Data source Education Statistics and Measurement Unit, Centre for Education Statistics and Evaluation.
