Hello clumsden392! I went to the last UDM program presentation meeting, and was told by a PA faculty member who is also on the admissions committee that they will be sending out invitations for interviews during the first two weeks in March, with final admission decisions being sent out on April 15. Also, we were told that out of more than 1300 applications to UDM this cycle, only 250 were considered "complete" in order to be reviewed. Of those, they will offer 80 interviews. Right now there are a total of 40 seats open for the class of 2018, BUT 10-11 of those will be automatically filled by UDM undergrad pre-PA students who made the GPA cutoff. So basically 1300 --> 250 applicants for 29 or 30 available spots, with acceptances going out to less than half of those interviewed: very competitive numbers!
Also, the faculty member told us that UDM will be DOUBLING its program size starting with the class of 2019. They are in the process of getting approval for adding on to their structure with new facilities. So it will be decidedly less competitive to get in starting next year. That doesn't help the 2018 hopefuls though-- so best of luck to all of us! I was very impressed with the program compared to others after this presentation and my conversation with the instructor.
Hope this helps!
