Dr. McCoy was a Lieutenant Commander before he joined the Enterprise. Doing an extras course to become CMO seems a bit over the top to me, as well as a waste of time.
Certainly, in civilian life, today, there is no extra training or anything like that for becoming Chief of Staff at a hospital, as long as you have the highest medical qualification and enough experience, which I’m sure Bones already had (he had been a doctor for over ten years by then). In the civilian system you get interviewed by an executive committee who will decide to give you the job depending on your merit from your previous positions and possibly the research you have done (Bones also had a lot of credit here, having pioneered new treatments). So if this is the case why should Starfleet require their potential CMOs to do an extra course? After all, how would running a sickbay with a staff of maybe two dozen be more complicated than running a large metropolitan hospital with a staff in the hundreds?
Also wouldn’t your suggestion mean that Commanders who become Captains would have to go to Captain school and Captains who become Admirals would have to go to Admiral school? Somehow, I doubt that this is the way it works. Being a good executive isn’t exactly something you can learn in a course anyway.
