A pathologist on reddit (yeah, I know, it is reddit... you can't take it too seriously) just described the Pathologist Assistant education as "on the job training with lectures".
Well... isn't all medical training that? Clinical rotations are OJT in a much more standardized form where you try to ensure that every student passing through has roughly the same guidelines and instruction. And sure, I guess if you wanted to be dismissive you could describe a grueling year of medical education as "lectures".
I suppose, if you wanted to paint with such broad strokes medical school, residency, and fellowships are also OJT with lectures. Nursing is OJT with lectures. Physicians assistants get OJT and lectures. I would hope that in regular life the pathologist who posted is not quite so dismissive of other's education.
