Enrolment and attendance data is collected eight times per year (at the beginning and end of each term). In each term the first reporting period covers weeks 1 to 4, and the second reporting period covers weeks 5 to 8. The average enrolment number is the average enrolments of students over the four-week reporting period. The attendance rate is the proportion of time students attend compared to the time they are expected to attend during the four-week period.
New enrolment and attendance processes were introduced in 2013 that provided a richer, more robust and highly validated dataset. Due to these enhancements, 2013 represents a break in series and therefore enrolment and attendance data prior to 2013 cannot be compared to datasets for 2013 and onwards. Data is current at the time of publication.
