I am just getting started with credentialing here (we have 30 providers with new hires every other week and have added 3 locations this year and will be adding another soon, there is a lot to do). I agree that it's not really something that can be easily taught. It's mostly about following instructions, checking off boxes, paying attention to details, responding to the credentialing reps, etc. Pretty basic data entry for the most part. It's just important to be able to do everything correctly and stay very organized. I have nothing to do with contract negotiations, I'm just adding new locations/enrolling providers to our existing contracts which were negotiated by our office manager (who originally used a legal team specializing in this but after so many contracts I think she understood them well enough that she mostly does them herself now). It's slow going the first time around for each insurer because they all want different things for different providers, but once you get through it once it becomes easier. I guess the upside is it costs you nothing to learn through experience (except time and possibly your sanity).
