Signing Out

It is best, where possible, to make medical appointments outside of school hours.  If you need to leave school during the day for any reason, then please ensure your son/daughter brings a note in advance of the date, and gives it to the Attendance Officer.  Students must sign out with either the Attendance Officer or at Matron’s office.  If your son/daughter returns to school later on the same day then they must sign in again.
