EMPA Deadlines page:
The EMPA program follows a rolling admissions process. That is, there is no firm deadline to get your application in. Rather applications are received throughout the year and considered as we receive them. It is best, however, to submit applications for the fall semester by February 1 and for the spring semester by August 15.
Applicants may request transfer of up to 6 credits of graduate-level coursework completed at an accredited graduate institution. If you plan to transfer credits towards your Executive MPA degree you can start the process once you have been admitted to the program. If your descision to enroll in the program depends on the credit transfer; your advisor will be able to tell you if the transfer requests will be approved or not.
