Frequently Asked Questions

Why did Harvard Law School create Zero-L?

Zero-L was created for students who are about to start law school but who haven’t yet crossed the threshold to their first or “1-L” year—hence the name “Zero-L”. Zero-L was designed to ensure that all these incoming law students, whatever their backgrounds and previous areas of study, start with the foundational knowledge to enable them to thrive in law school.

Who should take Zero-L?

Zero-L was built for incoming law students and, over the last several years, tens of thousands of incoming law students nationwide have taken Zero-L. Because Zero-L was built for students who haven’t yet started law school, Zero-L is also beneficial for everyone in the process of applying to law school, thinking about applying to law school, or learning more about the law for their own curiosity.

In accordance with Harvard University policy, Harvard Law School does not discriminate against any person on the basis of race, color, sex or sexual orientation, gender identity, religion, age, national or ethnic origin, political beliefs, veteran status, or disability in admission to, access to, treatment in, or employment in its programs and activities.

Please note that Harvard is not responsible for fluctuations in international exchange rates between payment and refund, nor is it responsible for interest charges or other fees due to the timing of credit card refunds.

How does Zero-L work?

Zero-L for individual learners is a fully online course that runs for six weeks, with new modules delivered every week and a brief online course orientation prior to the first module. All Zero-L content is fully asynchronous, so you can complete each module on your own schedule each week— you don’t have to log in at any particular day or time. Modules contain videos, vocabulary, and short exercises to check comprehension. The estimated amount of work time each week is roughly 2-3 hours, although individual learners’ timeframes will vary.

When is the next wave of Zero-L?

The cohort of Zero-L for individual learners begins with online orientation on Tuesday, June 10th, 2025, with the first module opening on Wednesday, June 11th, 2025. The course concludes on Wednesday, July 23th, 2025. Please check back here or sign-up to stay in touch with us for dates of future Zero-L individual learner cohorts.

I’m so excited to take and complete Zero-L. What happens when I finish?

Upon completion of Zero-L, individual learners will receive a Certificate of Completion. Please note that Zero-L is ungraded and that no degree or course credit toward a degree is awarded for Zero-L completion.
