The Graduate School, the University Libraries, and the Graduate Faculty of Penn State have established format standards that theses and dissertations must meet before receiving final approval as fulfillment of graduate requirements. The Office of Theses and Dissertations staff is responsible for verifying that all eTDs have met these requirements (refer to the Thesis and Dissertation Guide) . The text of the eTD should be proofread and free of grammatical errors and typos. It is extremely important that the author carefully review and proofread the thesis or dissertation before submitting the final document. After the official approval of the final eTD by the Office of Theses and Dissertations, changes will not be permitted.
