Important Information on PhD cross-Registration

Select offerings, excluding most core 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 Continuing Education (CE). 

Cross-registration seats are offered on a space available basis 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.
