Getting an error message?

In Course Search & Enroll, these look like

Course enrollment failed:
You were not enrolled. This class requires permission to enroll because the deadline to enroll has passed.

This is an accordion element with a series of buttons that open and close related content panels.

Enrollment requisites not met

Location of requisite informationSome UW–Madison classes are open only to students who have specific qualifications. These conditions are called requisites. Look for requisite information in two places: at the course level (“Prerequisites” in the main course panel) and sometimes at the section level (under “Enrollment Information” in the section detail.) Types of requisites include:

Classes. — The department expects students enrolling in the class have the knowledge gained from completing another specific class (or choice of classes). A prerequisite is a class you complete before enrolling in the current one. A corequisite is a class that you can, or are required to, take at the same time.

Class standing. — The class is open to students who are at a certain level, like sophomore or graduate standing.

Reserved for certain students. — Some classes are first held for students in a major, and then open at a later date to other qualified students. Other classes are designed specifically for students in a First-Year Interest Group, or a specific residential learning community.

The enrollment system checks your student record to confirm that you have met the requisites for that class. If you don’t meet the criteria set for a requisite, you’ll see an error message when adding the class to your cart.

Some students get a requisites error if their transfer credits are similar but not directly equal to the UW–Madison requisite course (example: ECON X10 Elective instead of ECON 101). The enrollment system won’t recognize those transfer credits as meeting the requisite. If this describes your situation, please talk with your advisor.

do this

Examine the error message to see the class’s requisites (highlighted in green):

Course validation failed: Enrollment prerequisites not met. Review the course prerequisites and course details before contacting the department offering the class. – Sophomore standing or one course in HISTORY, GEOG or ENVIR ST

Please contact the department offering the course for permission to enroll if you believe that you meet the requisites.

Information about requisites may also be shown in the Subject Notes for the course.

Instructor consent or department permission is required

In addition to requisites, described above, some classes have a special process that allows the instructor to approve who takes the class. Common examples are Independent Study and music performance classes.

Other classes will have enrollment determined by the department offering the class. Once the term begins, there are deadlines after which students need to get the department’s permission to add a class.

do this

Contact the appropriate instructor or department to request permission to enroll, and include your campus ID number. You may be asked for more information about your qualifications and interest in the class.

If the instructor or department approves you for the class, they will create as special permission for you in the enrollment system.

You still need to enroll in the class! Go to Course Search & Enroll or Student Center to enroll. Get in touch with the instructor or department who gave the permission if you still have problems enrolling in the class.

The hold must be removed before you can enroll

Course enrollment failed: You were not enrolled. The hold must be removed before you can enroll. Go to Student Center in MyUW to view your holds.

A hold is a temporary status connected to your student records, placed by a campus unit (academic department, library, Bursar’s Office, etc.) that wants to alert you of an action you need to take (meet with an advisor, pay a library fine, pay your tuition, etc.).

Some kinds of holds will prevent you from changing your class schedule, including enrolling in or dropping classes, until the hold is cleared.

do this

Find out what the hold is by checking Student Center.

Follow the instructions in Student Center to resolve the reason for the hold. Then, contact the campus unit that placed the hold, to confirm that they have cleared the hold for you.

After any enrollment-related holds are cleared, you can enroll in classes. Remember to check for any holds before enrolling for future terms!

Class is closed and wait list is full

The department offering the class has limited the number of students who can be on this class’s wait list. That list is now full.

do this

Since you can’t add yourself to the wait list now, check back from time to time to see if spots on the wait list open up.

Or, contact the department offering the class, as they manage the wait list. Although departments don’t generally share information like how long the wait list is, some may adjust the number of available seats (or wait list size) in high-demand classes.

Exceeded your credit maximum or minimum credits not met

Course enrollment failed: You were not enrolled. Enrolling in this course would have exceeded your credit load maximum.

UW–Madison has limits on the number of credits that you can take in a term: for Fall or Spring, 18 credits for undergraduates; 15 credits for Graduate School students; it varies for other types of students (Law, Medicine, Veterinary Medicine, etc.). Some types of students also have a minimum number of credits required for their program.

The enrollment system won’t let you enroll for credits outside the maximum or minimum allowed.

do this

Decide which classes fit your academic plan and still fall within your credit limit. Use the Save for later option in Course Search & Enroll to take a class out of your cart and bookmark it for enrollment in a later term.

If you have enrolled in classes that allow you to choose how many credits you earn (“variable credits”), you may be able to change those credits to fit within your maximum.

Use the Swap feature to enroll in one class while dropping another. Swap won’t drop the other class until you have successfully enrolled in the new one.

Contact your academic dean’s office if you want to request an exception to the maximum or minimum credit limit. Tuition is assessed according to your enrolled credits, among other factors. Your tuition rate may change if you enroll in credits above the maximum limit.

Deadline to drop class has passed

Each class has a drop deadline, and up to this date you can drop the class on your own using Course Search & Enroll or Student Center. After this deadline, however, you need to request permission from your academic dean’s office. This message says that you are trying to drop a class after its “self-service” deadline.

You do not have a valid appointment

Course enrollment failed: You do not have a valid appointment at this time or your appt date/time has not been reached.

To enroll in classes, you are assigned a specific enrollment appointment time, which is the earliest that you can begin enrolling in classes for a term.

This message usually means you’re trying to enroll in classes too early, either before the appointments have been assigned, or before your personal appointment time has arrived.

do this


Find your own enrollment appointment time, and when these are assigned (and emailed) to students.

If you get this error message and you have confirmed that you enrollment appointment time has already arrived, please contact us.

Please also contact us if you believe enrollment appointment times have been assigned to students (check the dates on this page) and you do not have one.

You are not able to enroll in courses

Only UW–Madison students who have been set up in the enrollment system as eligible to take classes are able to enroll.

This message will be shown to users who are not students but can still use Course Search & Enroll for searching, like UW–Madison employees.

If you are a student, you may see this message if your student status has changed, such as: 1) you graduated and haven’t yet completed the re-entry process; 2) you studied abroad in a program not affiliated with UW–Madison and haven’t yet completed the study-abroad re-entry process; or 3) you have not been enrolled in classes for a semester or more (also requires the re-entry process).

If you are a student and you think you should be able to enroll in that term, please contact us and we’ll help.
