Video Course Guidelines

Video courses at Harvard Extension School feature recordings of lectures held on campus at Harvard, including videos of Harvard College lectures. You can find these courses via the course search.

Online-Only Courses

Our online-only courses feature videotaped lectures of on-campus courses. Videos are posted on the course website weekly. There is no scheduled class time, so you can watch them at any time during the week.

Online Option in On-Campus Courses

These courses meet on campus each week, and the lectures are videotaped and posted online. If you enroll in courses with an online option, you can attend lectures in person, watch them online at your convenience, or both.
