The Spring 2025 CBS cross-registration period for eligible B9XXX courses runs from January 23rd to 31st, 2025. The last day to drop an A/Full-Term Spring course is January 31st, 2025.
Registration for non-PhD and MS students is always on a space-available basis after the PhD initial selection process is complete.
Note: the information on this page only applies to Doctoral courses, which meet primarily on Monday through Friday on standard daytime hours.
Important Information on PhD and MS Cross-Registration
Select offerings, excluding some core doctoral courses, are open to all currently enrolled Columbia University, Teachers College, and Union Theological Seminary graduate degree candidates, as well as post-baccalaureate students in the School of Professional Studies (CE).
Cross-registration seats are offered if space is available after the PhD and MS Programs selection process is complete. Note that not all PhD courses will be available for cross-registration, due to issues of capacity and pedagogy, and there is no process for requesting seats in courses not included in the posted list of cross-registration course options. These classes are available in SSOL and we encourage you to add and drop classes there.
