I'm wondering the same question. According with the "Duke Fall MSN 2020" thread, one of people there said this:
""With regards to admissions percentages, I asked Nora about that a month ago. She said that she really couldn’t give numbers/percentages because it varies widely based on the applicant pool. But a couple other sources:
1. There’s an old post on allnurses somewhere (I can’t find the link now) that quotes Nora telling someone that a few years ago, they admitted roughly 60-70% (2/3) of those they interviewed. That’s old info and may have changed, but it kinda lines up with the next bit.
2. I watched the informational video for the WHNP program specifically for those applying for this fall term. The video was recorded last August and featured the director of the WHNP program and one of the admissions officers. The director stated they receive roughly 25 WHNP applicants each term, and they try to keep the cohort size between 6 to 12 at most. So if they only offer interview invites to half and then accept 2/3 of those interviewed, that would line up. But again, bear in mind that a) applicant pools can vary widely from term to term, and b) that info was specific to the WHNP track and may differ from other specialties/tracks.""
