You will find the department’s policies and requirements outlined in our Department of History Graduate Handbook here.
You are also subject to the policies outlined in the Graduate School Catalog, which is available online (http://catalog.utk.edu/index.php?catoid=21).
Before emailing the DGS or graduate secretary with a question, please check these two sources first! Often you will find all the information you need in these two documents.
The American Historical Association also issues a Guide to Graduate Study, available as a pdf here.
