Holds are placed on a student's account to restrict access or use of an academic function (i.e., registration). Holds are placed for a variety of reasons including unpaid balances, parking tickets, library fines, disciplinary action taken by the Office of the Dean of Students, etc.
You are able to determine what hold(s) are placed on your account and which office to contact to resolve the hold by Logging into AppalNet > clicking on Self-Service > Student > Student Records / Student Account.
