Definition
Metadata for the IAC0414 table containing 1997-1999 and 2002-2024 data on the number of NSW government secondary schools by size. Note that this does not cover tables in individual fact sheets.
- 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.
- 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.
