Is it possible to commission through ROTC to anything other than 2LT by entering into a specific AOC? Ex Nurses or Clinical Lab Scientists?

1LT (Join to see), I responded to the other two responses on here to make sure that you are getting the correct information. There is a direct commission ability that the military has which can bring people in at different ranks depending on their specialty. I know of a pharmaceutical biologist who was allowed to direct commission as a captain, but that's the highest I personally know of. It is POSSIBLE that there may be direct commissioning at a higher grade, but those instances are RARE and you would have to have something akin to a Nuclear Physics PhD to even be considered. The basic answer to your question is no. Nurses will commission as a 2LT. Clinical lab scientists is an interesting field and I assume you'd have to have an MD. If it's a role normally filled by a LT, then no. It will be medical specialty corps and filled by a 2LT. If you are talking about an MD or a PhD in biology or chemistry, then...maybe. 99.9999% of officers come in as 2LT's. If you are looking to skip that grade, you have years of school ahead of you and a lot of time working in the civilian world to get enough experience to enter in that position at a higher rank.

Yes, You can for example a Doctor that is a member of our American Legion post went to ROTC and entered the US Army as a Lt. Colonel. Nurses and most others though would enter though would enter is 2Lts. That isn't common but it does happen although not too many Doctors take an ROTC route as far as I know. One Memorial day He came and brought with Him some of the newly Commissioned 2 Lts that had been in ROTC with him and lived in our town. He also brought the Army Officer who was in charge of the ROTC Battalion. That same Doctor now has been selected for promotion to Full Colonel.

1LT (Join to see) not that I am tracking. With that being said there are programs that instead of being in the operational force as a 2LT you continue your degree until completion. I had a classmate who pinned 2LT with me and then did one last year of school to finish her medical degree and shortly after pinned 1LT, so in reality she showed up to her first unit as a 1LT.
