Closings and Cancellations

Dean Fried, in consultation with senior staff and other Columbia University officials, may choose to close Columbia Mailman School under certain circumstances, including those days when travel to and from campus may be difficult. If Columbia Mailman is closed, the Allan Rosenfield Building (722 West 168th St.) will remain open for essential staff unless otherwise noted. Teaching faculty may also decide to hold classes off campus or via Zoom. 

Remote Learning

In cases where your class may not be able to meet on campus, please determine the appropriate remote learning option to replace in person class time and ensure course continuity. See Remote Learning Plan: Guidelines for Faculty.

The University has made Zoom available to all faculty and teaching fellows who needs to conduct a class remotely. Instructors should contact the appropriate department administrator or academic liaison to receive a link to a specific Zoom classroom meeting. Once the link has been created, instructors should invite students to the Zoom session via Canvas or email.

Class Cancellation Procedure

If the School remains open but faculty must cancel class, they are expected to take these steps:

  • Inform the Office of Enrollment Management of the cancellation: Cancellations and any questions should be directed to Carlos Correa, Director for Enrollment Services ( 

  • Notify the students: If available to the professor, an email should be sent to the class roster, as soon as possible and preferably by 5:00 a.m. to accommodate the needs of commuting students. Faculty may choose other methods of communicating class cancellations.

Closing Updates

When appropriate, timely information will available online, via email, and by calling University Security.
