What happens if you don't get accepted into med school after ROTC?

You would serve out your contract. If you're on active duty, that complicates the timing of pursuing med school more so than being in the Reserves or NG. You likely could pursue med school while still under contract, without necessarily incurring more of a service commitment.

You should talk to an ROTC instructor and a medical recruiter (from whichever branch of the military you're considering) to see what options you might have coming out of ROTC. They can provide much more clarity.

I believe the military has slots in certain med school. And if you are accepted to one the military pays and you get a longer time to serve as a result of that. That length of services depends on total schooling including residences. I would recommend contacting one of the 6 senior military schools ROTC recruiting office they can explain it better. The 6 senior military schools are from north to south to west, Norwich in Vermont, Virginia Tech in Virginia as is VMI, Citadel in SC, University of North Georgia in Georgia and Texas A&M in Texas. They have alot more information. But you can check with any school that has ROTC program and pre-med bachelors degree and if the are a feeder to a med school. Makes getting accepted easier. But check with the senior military colleges first as they deal with it alot and would have the most up to date info.

It’s not an automatic, you have to request and receive an education delay through your PMS. Predicated on being accepted.
