You should discuss your submission plans with your supervisor, though ultimately it is your decision when to submit your thesis for examination. About two months before you expect to submit your thesis, you should complete the ‘notification of intention to submit’ in your e:vision account (located under ‘Research Progress’ within the ‘My Supervision Meetings and Research Details’ section). This allows the department to make the necessary arrangements for your examination. You do not need to be over-exacting in calculating your submission date, provided that you adhere to your deadline for submission.
When to submit
You must submit your thesis by the final deadline, though it is a good idea to plan to submit long before that, in order to give yourself time to deal with unexpected events in both your research and your personal life. You can see your submission deadline in your SkillsForge account. Late submissions will only be accepted once an extension has been applied for and approved. A pending extension request is not sufficient.
Should you have a request for an extension to submit pending at the time of your deadline, you are strongly advised to submit a digital copt of your thesis in order to avoid automatic failure for non-submission should your extension not be approved. RSA can provide details on how to submit your contingency copy: https://www.york.ac.uk/research/graduate-school/support/rsa/
How to submit
Theses may are required to be submitted to the Research Student Admin (RSA) team by hand via the Student Hub (prepared and submitted for examination as specified in the University's requirements (https://www.york.ac.uk/studentsresearch/support/student-support-hub/), by post, or by courier servicegraduate-school/academic/thesis/format/). It is your responsibility to ensure that the thesis reaches RSA (via the Student Hub) by the deadline.
