Courses on Lagunita are either offered in a self-paced mode or a live, instructor-paced mode. Many of the courses run periodically. However, we do not know exactly when old courses will run again.
We recommend checking our list of Courses page, lagunita.stanford.edu/courses, periodically to see if the course you're interested in is available for enrollment. Other Stanford-run online courses can be found at online.stanford.edu/courses.
After live courses end, enrollment tends to stay open. You are welcome to sign up for courses even if their official class end date has passed, provided the course has not chosen to set an enrollment end date. The course materials may stay available, but you won't be able to earn a Statement of Accomplishment for your work after the course officially ends.
