Class Standing: is determined on the basis of graduation credits, completed or in progress, as follows:

Freshman Fewer than 24 credits

Sophomore 24-55 credits

Junior 56-87 credits

Senior 88 or more credits

Senior Registration Policy: Seniors may not enter 100-level courses during the Advanced Registration or Registration Periods without permission of the Office for Undergraduate Education. Seniors may enter 100-level courses beginning on the first class day of the semester.

Deregistration of Students Who Do Not Have Appropriate Prerequisites: If students lack the appropriate course prerequisites, instructors should ask students to drop the course. If a student refuses to drop the course, the instructor may, at any time during the semester, request that the Registrar deregister the student. The Registrar will assign a grade of W for students who are deregistered after the Program Adjustment Period. The Office for Undergraduate Education urges faculty to inform their classes during the first few days of class if they intend to apply this policy. In any event, faculty should apply this policy consistently and, if possible, early enough for a student to switch to a different course.

Deregistration of Students Who Fail to Attend Class: Beginning on the seventh day of classes instructors may deregister students who fail to attend class, explain their absence, or officially drop within the first six class days of a term, unless prior arrangements to preserve the registration have been made by the student with the instructor. In the case of classes which meet once a week, including lab courses, the instructor may deregister students who do not attend the first scheduled class. Instructors should keep careful records and be consistent if choosing to implement this policy. A “class day” is defined as any day from Monday through Friday in which classes are in session and the Registrar’s Office is open.

Adding Classes Beyond the Deadline: Students should contact the Registrar’s office regarding the limited appeals process and should be prepared to document the extenuating circumstances that prohibited them from registering in a timely fashion.  Students should not attend classes that they are not registered for.

Last Day to Drop a Class: From the first class day through the tenth class day of the semester, students who drop a class will have that course removed from their record. From the tenth day of class through “the last day to drop a course,” which is specified in the Undergraduate Bulletin as 15 class days after the midterm point for semester length courses, students who drop a class will receive an indicator of W on their transcript. It should be noted that the “last day to drop a course” differs between undergraduates and graduates, with the undergraduate date being approximately two weeks later.

Late Withdrawals from Courses: The various deadlines for dropping and adding courses are well publicized, and students are responsible for observing them. Occasionally a student will petition the Committee on Academic Standing (CAS) for a waiver of the deadline to drop a course. Forms for this purpose are available  online on Office for Undergraduate Education's website, In general, only cases which present documented extenuating circumstances beyond the student’s control are likely to be approved. If approved, these petitions result in a W for the course. The petition process involves consulting with the faculty about attendance and grades assignments and they can comment on whether they support the withdrawal request. The faculty recommendation is carefully considered by CAS; however, the outcome of the request is not determined exclusively by the faculty recommendation. Students sometimes erroneously assume that because a faculty member strongly supports their petition it is certain to be granted. This is not true. Please take care not to suggest otherwise to students.
