To do this, you complete a form and send it to the Graduate School Secretariat. An extension is usually for a maximum of 12 months and you must be able to document financing for the extra enrolment period. Please note that if you are employed full-time as a PhD student, this employment period cannot exceed 36 months.
In the event of an extension, your PhD plan will be adjusted accordingly. Note that half-yearly reports will still need to be send in every 6 months until you submit the PhD thesis.
Illness
If you experience long-term illness (more than 4 consecutive weeks), you can be granted an extension of your PhD period. You can apply by submitting a written application (find it here) to the Head of the Graduate School, explaining the circumstances and enclosing a documentation for financing of the extension. (A statement from your doctor might be needed by your employer for the extension of the employment, please contact your employer for information about this). The decision is based on individual assessment of each case. If granted, the period of enrolments will be extended accordingly (including the deadlines for the half-yearly reports).
