Late registration is not permitted, so be sure to register by the registration deadline. For information on making course changes after registering, see course changes and withdrawals. See the academic calendar for additional dates and deadlines.
You must be at least 15 years old at the time of registration to register for undergraduate credit or noncredit, and at least 18 years old to register for graduate credit.
If your native language is not English, you must also meet the English proficiency requirement before you can register for courses or take the test of critical reading and writing skills. We encourage you to review these requirements and other enrollment policies before registration opens.
You must pay your balance in full by the payment deadline. If you do not, you risk being dropped from all courses and waitlists. If you are dropped for non-payment, you still remain eligible to register for courses until registration ends. However, there is no guarantee space will still be available in the courses or on the waitlists from which you were dropped.
If you register for courses after the payment deadline, you must pay in full immediately. Otherwise, you risk being dropped from all courses and waitlists.
Your Registration Confirmation
After you register, you will receive a confirmation by email. Carry this with you when you are on the Harvard campus. For security reasons, you may be asked to present your confirmation with a government-issued photo ID for admission to certain classrooms in the Science Center, Longwood Medical area, and other buildings and areas on the Harvard campus. You may also print a copy of your registration schedule from online services.
