Thesis or dissertation students: Your defense date must precede the deadline for format approval listed on the Graduate School's website if you would like to graduate in the same semester. Instructions for defending your topic or thesis.
Project students: Make sure your defense date precedes finals week of the semester you intend to graduate (e.g., defend before Dec 12 for Fall 2016 graduation or before April 27 for Spring 2017 graduation). Instructions for defending your project.
If you do not adhere to these deadlines, you may not graduate in your desired semester.
