The collection took place in March when schools were impacted by COVID-19, so fewer data checks were carried out.\n</li>\n<li>\n\nStudents attending schools for specific purposes (SSPs), students in support classes in regular schools and distance education students are excluded from average class size calculations.\n</li>\n<li>\n\nThe 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.\n</li>\n<li>\n\nFrom 2017, school size is based on primary enrolment rather than school classification.\n</li>\n<li>\n\nSchools change size, so data in Table 2 is not necessarily comparable to previous iterations in earlier fact sheets.\n</li>\n</ul>\n\nData Source\n\nEducation Statistics and Measurement, Centre for Education Statistics and Evaluation. \n\nData quality statement\n\nThe <a href=\"https://metadata.nsw.gov.au/item/13132/qualitystatement/class-size-audit-data-quality-statement\">Class Size Audit Data Quality Statement</a> 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.
