Full- and Part-time Study
One credit in a Harvard Summer School course is equal to 1 semester hour. Credits are listed in course descriptions.
Full-time enrollment
Eight credits constitute full-time enrollment.
All study abroad programs and Institute for English Language intensive programs are full time. If you are a Harvard Extension School degree candidate enrolled in ENVR S-599 or a thesis or internship course, you are enrolled full time. I-20s are issued only to students who are enrolled full time.
Maximum enrollment
Your final enrollment cannot be more than 8 credits for undergraduate or graduate credit. If you are a student in the general program, you may enroll in an additional 4 credits for noncredit. (Enrolling in classes for noncredit is not an option for Secondary School Program students; enrolling in more than 8 credits is not an option for IEL Intensive Program students.)
During registration, you can register for up to 12 credits, including waitlisted or waiting-for-placement courses. By May 21, you must drop any courses over the 8-credit limit or you will be dropped from the overload courses. Exceptions to this policy will be made only when the course overload is balanced by your waitlist status in another course, or if you are a Harvard University degree candidate who has received approval for a course overload. Harvard College students and Graduate School of Arts and Sciences students: see maximum-enrollment guidelines in your section of Harvard University Students.
If you are enrolled in 12 credits and your account balance is not paid in full by the May 21 payment deadline, the Registrar’s Office will drop you from a 4-credit course.
Time conflicts
You may not be enrolled in courses that meet at the same or overlapping times unless at least 1 of the courses is also offered online and is not a web-conference course.
If you register for courses with time conflicts, you must drop 1 or more of the conflicting courses by Monday, May 21, or you will be dropped from those courses by the Registrar’s Office.
Calculating enrollment status for enrollment certifications and loan deferments
Only courses taken for undergraduate and graduate credit are included in calculations of enrollment status for enrollment certifications and loan deferments.
Courses in which students receive grades of excluded-from-the-course (EXD), required-to-withdraw (RQ), administrative withdrawal (WA), or withdrawal (WD) are not included in those calculations.
