I don't know that the number of prior nursing scholarships is available publicly. The scuttlebutt on the foums is that there are few nursong scholarships these days. Nursing scholarship is handled by a separate board, full of medical officers as you might imagine. It only meets once or twice a year, at most. If you're interested in NROTC nursing you should apply. I think Army has more opportunity for nursing scholarships, at least in raw numbers.... or so the theory goes. It might be smart to apply to both, or all three?
