(previously known as extending your registration date)

Students have a deadline by which to submit their thesis for examination which is set as four years for full-time students and seven years for part-time students.  You should make every effort to meet your deadline.

If however, you are not able to submit your thesis by the last day of the fourth year after you have been formally registered as a full-time candidate for either the PhD, MSc or MLitt Degree (or the last day of the seventh year if you are registered as a part-time candidate), you must apply to extend your submission deadline.

Please note that for 2010 PhD cohort onwards, PhD, MSc and MLitt students will be automatically removed from the Register of Graduate Students at the 4 year point, unless an application to defer is agreed by the Board in advance of the 4 year date being reached.

Applications can be made via your CamSIS self-service account, using an application called ‘Extending your Registration Date’.

Any application must be completed (you have received the decision from the Board) before you reach your current 'End of Registration Date'.  You should allow at least three months for any application to be processed.

All applications are considered on their individual merits by the relevant Degree Committee in the first instance. Your progress to date will be taken into account as will your supervisor's comments. It should not be assumed that an application to extend your registration date will be approved as a matter of routine. Applications will be automatically declined by the Board if you do not confirm on your application that you are fully engaged in your research, and based in Cambridge.

It is open to the Degree Committee and/or the Board to decline applications and remove students' names from the Register of Graduate Students. This does, however, normally leave open the possibility of being reinstated at a later stage when you wish to resume your registration, if your dissertation is ready for submission (see 'Reinstatement to the Register for Graduate Students').

Please let your College and funding body (if you have one) know if you are making an application to extend your End of Registration Date - you may also need permission from your funding body.

Please note: if you are an overseas student requiring entry clearance to study in the UK, please ensure you comply with the conditions of your visa. For visa information please contact the International Student Team (

Please note that you do NOT need to apply to extend your End of Registration Date if you have submitted your dissertation for examination. However, you will have been advised by the Board of the outcome of the examination process that you are required to undertake corrections or are required to revise and resubmit your dissertation and you wish to extend your registration beyond the date agreed by the Board.
