Cornell University School of Continuing Education and Summer Sessions

Winter Session 2020 will run from December 26, 2019 to January 18, 2020, with three-week on-campus classes beginning on January 2, 2020. We will update the Winter Session site in September. If you would like to receive an email when this happens, please join our email list. In the meantime, you may want to browse through the site to get an idea of what we offer.


The "coolest" season at Cornell, Winter Session is a great opportunity to earn up to four credits in just a few weeks, enjoy small classes, concentrate on intensive study, and get to know your professor and classmates.

What our students are saying

"I highly recommend the Cornell Winter Session. The classes are small and fast paced, and the students are self-selected and motivated."
