When applying, you should apply for your ultimate degree goal. A Master's is not needed to apply to the Ph.D. program UNLESS the Bachelor's degree earned was a three-year program. If that is the case, the applicant must have completed or be in the final year of a two-year MS program when applying. The MS degree must be completed before classes would begin here in August of the year for which you are applying.

Current master's students wishing to move to a doctoral degree program in this same graduate program will not be required to submit a new application.
