In some cases, a limited number of graduate level course credits can be transferred from another institution and applied toward a master’s or PhD. These credits must be approved by your faculty advisor and the Graduate School.

Credits from a completed master’s program cannot be transferred into a current master’s program. A maximum of 9 credits can be transferred to the MS program, and a maximum of 18 credits can be transferred to the PhD program.

Enrollment can be deferred for up to one year from the original application term. An e-mail request must be sent to the graduate program advisor for a deferment.
