No offense taken, but I think you need to re-read the thread title, this is about AFIT. AFIT is a small, small part of the AF. It is a graduate school that is run through the AF. I also addressed many issues on my 1st post (#2 on the thread)
I am not sure what you want to learn about the AF V Navy on this thread. Both branches have graduate programs. I am not versed in Navy, but I would assume they have their equivalent to AFIT.
My comment to Hornet and Eagle was made in hopes they would chime in, since they are both opting grad school on the AF dime with a UPT follow on. They are the most current posters that can give info. They will be commissioned in @2 weeks from the AFA.
My comment to you, was it is great to have plans, but right now your biggest concern is to not let your DS/DD be one of the 28.75% that enters, yet leaves without experiencing commissioning at the AFA.
Even a broken arm at BCT could quash that dream. Live for today, but plan for tomorrow. I have a great friend who has a DS at USNA. He entered 2 yrs ago, and at first he was going to be a SWO. Then it was submariner. Now he wants to fly. Things change. Things happen.
The military is not a career you can plot and plan 3-4 yrs out for specific careers, especially as a cadet.
Your child may want grad, med, law school right out of the SA. However, each branch has these options. The real factor that needs to be addressed: First, what branch they want to spend the next 9 yrs of their life (4 at the SA, 5 AD commitment). Next, graduating. The third would be that academically they are the top of the class. Fourth, command support. Put all of that together and you get why I said you are placing the cart before the horse. Grad school options should be the least of the concerns.
Let's use statistics as an example, 1400 enter, 1000 graduate, maybe 50 of them get some form of grad/fellowship. The statistical chances of receiving AFIT/grad out of the AFA is @3% of the entering class. The chance of graduating is 72%. The priority IMHO is graduating. Statistically the odds of AFIT/Fellowship are not high, thus you are placing the cart before the horse.
