Cornell University School of Continuing Education and Summer Sessions

Winter Session 2018 will run from December 26, 2017 to January 20, 2018, with three-week on-campus classes beginning on January 2, 2018. We will update the Winter Session site in September. If you would like to receive an e-mail notice when this happens, please join our e-mail 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

"You learn so much and don't have competing classes or obligations--you can spend time with the material and schedules are more free. It's a great time to take a course you might find challenging."
