The Navy obtains the majority of its Physicians Assistants through direct commissioning, that is, they attend undergraduate college, then PA school and apply for a commission. If they are successful, they go through some Navy Officer training and then go on to work in Navy medicine. Many take advantage of the Health Professional Scholarship Program (HPSP):
NROTC’s mission, Navy Option, is to produce officers to go into the unrestricted line warfare communities noted in link below. That is the price of a generous scholarship. There might be an occasional case where a NROTC grad is allowed to go to medical school, but that is a rare exception. I don’t think there is a path to PA from NROTC, though that doesn’t mean it’s never happened.
Navy warfare officers can apply for lateral transfer into other communities at certain points in their career, usually after they have become warfare qualified in their own community, and if the “needs of the Navy” has spots available in the target community, and if the officer has a stellar performance record.
Navy warfare officers can also serve long enough to earn their veterans’ Post-9/11 GI Bill Benefits, separate from the Navy, use those generous benefits to apply for PA school, and then go on to a civilian PA career or apply for a commission as a PA in military service and come back in through a direct commissioning program.
You have done well to earn a NROTC Scholarship. Time to go back and read everything you can about the program and what is expected, and be fully prepared to enter one of the specified line warfare communities. That doesn’t mean you can’t ask about the possibility, but I think it would be a rare exception, especially if your warm body is needed in a line warfare community. Unlike regular college scholarships, which are gifts of financial assistance, the NROTC scholarship is a two-way deal. The Navy pays for your undergrad education as long as you meet required performance and academic criteria, and you pay them back by agreeing to give them X years of your life working in one of the allowed Y communities which they need to annually replenish with Z number of new officers.
I am not an official source. This is just my understanding of how NROTC generally works. You will want to research this at official sources. One thing I am sure about - do not take on this scholarship and obligation if you have no desire to serve in the warfare communities listed above. Of course, you can use it your first year and decide to walk away with no obligation.
