Semester Dates and Deadlines

Below are important dates related to registration and grading.

For holidays, commencement, and other dates, please check the Academic Calendar.

Tuition Refund Policy

Columbia will refund 100% of tuition and fees for a course that is dropped within the add/drop period for that course. The add/drop period for a course is dependent on the start and end date for that course. After the add/drop period for a course, the student is responsible for 100% of tuition and fees associated with the course. 

Students who never begin attendance in any course for the term and who fail to properly drop their courses during the add/drop period may have their schedules canceled by the Office of the Registrar. At Columbia’s discretion, a $75 per credit hour fee may be assessed to cover the administrative costs associated with the student’s failure to properly drop their course schedule.
