What’s the process like for graduate level ROTC (Army)?

I am close friends with a guy who is completing his Master's, a year under me in ROTC. His ROTC experience is ultimately no different than anyone else, he is held to the same standards and gets little to no "extra credit" for being older or in grad school. For his case, it was as easy to get into ROTC as it was for anyone else.

The real question is can you make the cut every year and can you score well on your OML.

Contact the Recruiting and Enrollment Officer (ROO) at the university you wish to attend. S/he will be able to give you the most current guidance.

The process is the same, but the experience will be different. Unless you are taking an easy grad program (which I don't recommend as it's a waste of your time and money), it will be far more difficult for you than the other cadets, particularly if you decide to take a thesis. As one of the comments alluded to, it is recommended to score high on the OML. To score high on the OML, you need to be in positions of leaders in your ROTC program and participating in color guard, ranger challenge, etc. That takes time.

Your ROTC program will also be condensed. Most grad programs are two years, ROTC is meant for 4. You will have to take additional ROTC classes or extend your grad school out to 3 years.

Honestly, I don't recommend doing it. I would rather have focused on my studies and then done OCS after I graduated.
