When do STEM academics learn how to manage funding? I'm from the humanities, where research grants etc. are scarce. Also, training to deal with research grants and external funding is nearly non-existent in my field.
I'm curious as to how graduate students in more external money-heavy areas like engineering or medicine (or maybe even computer science?) learn how to manage a lab.
I saw Managing lab funds , How does laboratory funding and money management work in grad school?,  and a few other posts but it still feels opaque to me how people become adept at managing research money at scale — and yet this is a really central part of the job in many fields (but as I said above — not common in mine).
Presumably a lot of that money has allocation rules, accounting rules, and can be audited to insure compliance too.

Are there courses in graduate school?
is it learned informally from being a postdoc?
or does everyone take a funding management compliance course at their university?

Other questions indicate that people do have knowledge of this: Is it usually allowed to use grant money for voluntary contributions? but it’s hard to believe no one has an explanation of how they got this knowledge.
As with many parts of becomes a group leader and teacher, this is just something you are expected to be able to do. I was never given any training, it was just expected that I was clever enough to work it out!
&quot;allocation rules, accounting rules, and can be audited to insure compliance too&quot;  is usually handled by central admin who are professional accountants and administrators.
