If you are interested in taking a leave of absence from Columbia, your first step should be to speak with your Advising Dean in the CSA. Your adviser will be able to discuss the various types of leaves and help you assess if a leave would be beneficial for you.
Students take leaves of absence from Columbia for a variety of reasons. For more information about the length of time you can be away, tuition, financial aid, housing, and health insurance, and about procedures for returning from a leave, please make an appointment with your CSA adviser. You can also review Columbia's policies and procedures for Voluntary Leave of Absence and Medical Leaves of Absence. Please note to take a voluntary leave within an academic term, you must submit a petition to the Committee on Academic Standing. The petition can be found here.
