Average government primary school class sizes by school size (2009-2024)

The class size audit is conducted in all NSW government primary, infant and central (primary grades only) schools in March each year.\r\n\r\n### Data notes\r\n* 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.\r\n\r\n* 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.\r\n\r\n* From 2017, school size is based on primary enrolment rather than school classification.\r\n\r\n* 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.\r\n\r\n* Refer to the individual class size factsheet publication for further information and policy context.\r\n\r\n### Data source\r\nEducation Statistics and Measurement Unit, Centre for Education Statistics and Evaluation.\r\n\r\n### Data quality statement\r\nThe [Class Size Audit Data Quality Statement](https://metadata.nsw.gov.au/item/13132/qualitystatement/class-size-audit-data-quality-statement) addresses the quality of the Class Size Audit dataset using the dimensions outlined in the NSW Department of Education's data quality management framework: institutional environment, relevance, timeliness, accuracy, coherence, interpretability and accessibility. It provides an overview of the dataset's quality and highlights any known data quality issues.\r\n

每年三月，新南威尔士州（New South Wales，简称NSW）的所有公立小学、幼儿学校及仅开设小学阶段课程的中心学校，均会开展班级规模审计工作。

### 数据说明
* 就读于特定目的学校（Schools for Specific Purposes，简称SSPs）的学生、常规学校支持班学生以及远程教育学生，均不纳入班级规模平均值的计算范畴。

* 各年级的班级规模平均值，由包含该年级学生的常规班级及混龄班级计算得出。此种计算方式可能导致K-6整体班级规模平均值低于任一单个年级的班级规模平均值。

* 自2017年起，学校规模以小学招生人数为基准，而非原有的学校分类标准。

* 历年班级规模情况简报不会更新替换早年统计数据。学校规模会发生变动，历史数据展示的是对应年份的真实统计结果。

* 如需了解更多信息及政策背景，请查阅单份班级规模情况简报出版物。
