If you're going to be absent but you do not know the exact dates please contact your programme leader by creating an enquiry.
Depending on the length of time you will need to either submit an Authorised absence form or possibly interrupt your studies.
Home students can apply for two weeks absence (up to 4 weeks with sufficient evidence & reason).
International students can apply for a maximum of 4 weeks absence. All Absences must be supported by sufficient evidence.
Absences must be authorised by the Retention team.
The Authorised absence form can be located here:
