Cornell University Summer Session offers hundreds of regular Cornell courses taught by outstanding university faculty members. Enrollment is open to all—from undergrads to high school students*, professionals, alumni, and any interested adult.

Due to COVID-19, the 2021 Cornell University Summer Session will be held entirely online. Review the Summer Session 2021 updates for options, read about online study, and view summer courses.

With choices of 3-, 6-, or 8-week sessions, most classes leave time for travel or a summer job.

During any of the summer sessions, you can benefit from small classes, really get to know your professors, and meet interesting people from around the world.
