This refers to the nature and scope of the revisions required by your examining committee. In the case of minor revisions, your research supervisor will withhold their signature from the Doctoral Dissertation Approval form at the end of the defence; they will sign the form after checking that the required revisions have been completed. If substantive revisions are required, at least two examiners, including your research supervisor, will be selected to check the revisions and will withhold their signatures from Doctoral Dissertation Approval form until the required revisions have been completed. The revisions required by your examining committee and the names of the examiners required to check the revisions will be communicated to you at the end of your defence by the Examination Chair.
