Not sure which path is right for you? You can start with a single course. Then, continue coursework to earn a certificate — and ultimately stack all your courses toward a degree.
Considering Your Schedule
We offer full-term and short-session courses throughout the year. When you choose to start depends on your academic goals, life priorities, and course availability.

Starting the Enrollment Process
Review our Academic Calendar and add critical registration deadlines to your personal calendar, so you won’t miss important deadlines, including:
The payment deadline so you can avoid getting dropped from your courses for nonpayment.
The registration deadline so you don’t miss the chance to enroll that term.
While all our courses are open enrollment, there are several important enrollment requirements that you should be aware of before you begin the registration process:
If English is your second language, you’ll need to prove English proficiency before registering for a course. We have multiple proficiency options.
Reading and Writing Placement Test
Some courses — including many courses for admission to degree programs — require you to pass the Test of Critical Reading and Writing Skills (CRWS) before you can enroll. This free, online test helps ensure that your journey at Harvard Extension starts strong with the right course.
COVID and Other Immunization Requirements for On-Campus Study
You’ll need to meet vaccination guidelines to take courses on campus. This requirement doesn’t apply to online courses.
If you need support as you consider and choose a program, and you’ve never taken a course with us before, an enrollment coach will work with you one-on-one. Your coach can help you find a program that fits your goals and life, select courses, and finalize enrollment.
