What kind of unauthorised absences result in the issuing of a fixed penalty notice?

Where students are openly truanting (this includes students found during truancy sweeps by the police).

Absences from school which parents or carers are aware of, but that are not authorised by the school.

Holidays that have been taken in term time which the Headteacher has not authorised.

An unacceptably delayed return from an extended holiday if the parents or carers have not received permission beforehand from the school.

Regular late arrival at school (after the register has closed).
