Class Standing Restriction

Many courses are restricted to specific student classes (e.g., juniors, seniors). For the purposes of registration, your class standing does include your in-progress courses. If you wish to petition for an exception, you can seek a registration permission.

Student Attribute Restriction

Student Attributes are commonly used for Online Only, LA, and Kasteel Well students. If you are approved to take your courses online, you will receive this error when registering for in-person Flex courses. Likewise, undergraduates not approved to take online courses will receive this error for online courses. Undergraduates cannot mix Flex and Online courses.

Kasteel Well and Los Angeles students will also get this error if registering for Boston courses.

Please double check the course listing by clicking on the course title and looking at the Restrictions section. If you think you received this message in error, please contact contact the Registrar's Office.

Level Restriction

Undergraduate students cannot register for graduate courses, and vice versa. If you get a level restriction error you are most likely trying to register for a course outside of your academic level. Courses are accredited at the undergraduate or graduate level so exceptions unfortunately cannot be made here. Even if you could take this course, its credits could not be counted toward your degree.

Maximum credit hours exceeded

For fall and spring courses, undergraduates cannot register for more than 16 credits during the the first week of registration. After the first week, eligible undergraduate students will be able to register for 20 credits. If you are trying to overload a summer semester, or you would like to petition to have your overload eligibility requirements waived, please contact academicappeals [at] emerson.edu.
Graduate students may not register for more than 14 credits. If you wish to petition for an exception, you must get permission from your Graduate Program Director and Graduate Studies

Linked Section Required

To register for TH221 Scene Study I or TH222 Scene Study II, you must register for both a regular section and any "voice & movement" section (these have a "V" in the section number). The section numbers do not need to correlate. For example, you can register for TH221-01 and TH221-V04. If you get this error for a course other than TH221 or TH222, or have any questions, please contact the Registrar's Office.

This course cannot be repeated...

If you are registering for any other course:

Most courses can only be taken for credit once. Some courses can be taken multiple times. If you get this error, you are hitting the course's "repeat limit."

Either the course you're trying to register for is full, or the remaining seats in the course are reserved for other students. This is usually for Graduate courses that have seats set aside for Graduate Certificate students. Please note that the number of "Seats Available" on the course listing page does not reflect seats reserved for other students.
