The Chair's Report on the exam is considered a confidential correspondence between the examination committee and the Dean of Graduate and Postdoctoral Studies. As a result, it is not shared with the candidate.
At the end of the defence, the Chair will communicate to you the recommendations the examining committee will be making to G+PS. The Chair will also provide you with information about the revisions required to your dissertation before it can be accepted as final and which examining committee members will be withholding their signatures from the Doctoral Dissertation Approval form until the revisions have been completed.
