Corrections to your thesis

Where you are asked to make corrections or revisions to your thesis, the examiners’ report forms will provide details of these corrections. You may also be given information at the oral examination about the required corrections or revisions. You should make sure that you understand the nature of the required corrections and revisions and discuss them with your supervisor. 

It is important that you understand the differences between minor and major corrections and revision and resubmission of your thesis as the procedures when you have completed the corrections or revisions are different.


  • Minor corrections: normally one month (*)
  • Major corrections: normally six months (*)
  • Revise or resubmit: normally one year (*)

 (*) The examiners may give longer than this.

The email confirming the outcome of the examination will clearly state the deadline for submission of your corrected or revised thesis. 

You should take your deadline seriously, and work towards submitting your thesis by the deadline. You should continue to complete monthly online GRS2 forms to keep your supervisor in order to keep your supervisor updated on the progress of your correction.

If you are unable to meet the deadline, in exceptional cases you may request an extension to your deadline by submitting an extension request form for consideration by the University’s Research Progress and Awards Sub-Panel.

Further information about extensions can be found on the extensions webpages

Submission of corrected thesis (minor or major corrections) 

You are permitted one opportunity to complete corrections to the satisfaction of the examiners. You should raise any queries regarding the required corrections with your supervisor who will liaise with the examiner(s) on your behalf.

Your corrected thesis should be submitted electronically by email to your examiner(s), copying in Research Student Administration (

  • Minor corrections: to be checked by the internal examiner
  • Major corrections: to be checked by the internal and external examiner

The date on the cover page for a corrected thesis (examiners decision of minor or major corrections) should be the original submission date.

For information regarding resubmission of your thesis following the recommendation of revise and resubmit, see the revise and resubmit web pages.

The RSA team will provide your examiners with a deadline by which they should complete the checking of corrections and they will be asked to certify that the corrections have been completed to their satisfaction. RSA will then write to let you know whether the examiners are satisfied with the corrections.
