Regular attendance at school is essential if students are to maximise their potential. Schools, in partnership with parents, are responsible for promoting the regular attendance of students. While parents are legally responsible for the regular attendance of their children, school staff, as a part of their duty of care, monitor part or whole day absences.

The following is a few of the major points in Student attendance in Government Schools: Procedures School attendance policy PD20050259. You can see the full department policy here

Principals may grant sick leave to students whose absences are satisfactorily explained as being due to illness and leave to students of compulsory school age totalling not more than 15 days per school year in addition to sick leave.

Teachers are responsible for seeking verbal or written advice promptly from parents regarding unexplained full or part day absences. Parents may not be aware that their child has been absent from school and will expect to be informed promptly if unexplained absences occur.
Teachers must retain records of written, electronic and verbal explanations from parents.
Schools may wish to request this information by telephone.

Teachers must alert the principal or staff member responsible for monitoring attendance when a student’s pattern of attendance is of concern, or if no explanation is received from the parent or carer and report chronic non-attendance, fractional truancy and persistent lateness promptly to the principal or nominee. If a range of school based interventions has been unsuccessful, support may be requested by referring individual cases of unsatisfactory attendance to the regional Home School Liaison Program.
