This doesn't really address your question, but I hope you will accept another comment.
I have noticed in two of your posts you mention instruction/supervision by anesthesiologist. Of course you can learn anesthesia from MDA, and they are clinical instructors places.
It is my belief that most SRNA instruction is carried out by CRNAs. (This is based on my own experience, perhaps it is differnent other places.) And the supervising clinical director can be a CRNA. Places that don't even have MDAs can be clinical instruction sites, although each program does have to have a MD medical director.
I don't mean to make a mountain out of a molehill. I just think language is powerful, and even little details like this show alot about our values and perspectives.
The COA process that smiling_ru mentions is pretty involved. I know of schools
who limit their number of clinical sites because of it. But on the other hand, some programs have a huge number of clinical sites, so they have found a way to make it workable.
