Congratulations to your daughter for persevering!
Is there a published assignment list? If so, I'd be interested in glancing it over. As a side note, our son didn't pick his medical school selection until last week. So the data could be off some. In fact, D-day for selecting a medical school isn't over until month end. Then there is the wait list musical chairs portion before they finally settle in.
Our DS interviewed at USUHS. He really liked the school and the better stipend (with more commitment). He prefered the culture, location, and instruction better than a few top ranked civilian schools that he interviewed with. He concluded USUHS is a great school to study medicine. After a lot of back and forth trade-offs, he finally picked a medical school out east. I know one 2016 USAFA medical student that is off to UofMN and another Creighton. He didn't mention where the others are going (I think about 10 total students are off to medical school).
Outside of being an active military member like your daughter, getting an AF selection HPSP slot is tougher than say an Army HPSP slot. Hence it is very competitive. The Army for instances uses FIFO. Meaning once you are accepted to any medical or dental school as well physically qualifying, they fill their spots based off of 1st completed. But for the AF, they rack and stack to pick their overall best candidates (which they define as higher MCAT and DAT scores). Normally the average DAT and MCAT score are 2-3 points higher in the AF over the Army. This assumes a 4 year HPSP. For a 3 year (3 year scholarship ==3 year payback) the Army pools the remaining total and therefore is more selective on their 3 year option versus their 4 year. I guess future military docs like the AF bases better. Our daughter was offered and accepted a 3 year Army HPSP for dentistry. I do not know how the Navy picks their HPSP candidates.
