Registration holds are locks placed on the computer system that prohibit a student from being able to register or modify an existing schedule. Holds are entered by different offices for different reasons. You can see your hold in your myZou student center. Check to see what the hold is (for example, Past Due for tuition payment), and what office you should contact to have it removed (in this example, Cashiers). A student could have holds on registration for probation, filing graduation plans, immunizations, student affairs, advising, and more.
