Petition forms are required whenever a student needs permission to change status, register after deadlines, withdraw from classes, request a leave of absence, make a change in dissertation committee, etc. Please click here for complete petition guidelines. Be sure to explain fully the reasons for your request. In some instances a strong letter of department support may be required (for example, requesting a refund for a class). Petitions require signatures from student's advisor, graduate director and the graduate programs office. When a decision is rendered by the Registrar's Office, students will be notified via email.
