I asked this in another thread and someone expressed interest, so I'll post it as its own topic that might get a different viewing audience.
What martial arts credentials do you all think are necessary and/or nice to have to run or open a dojo? I'm not talking about business skills or things like that (which are obviously beneficial). And I'm assuming that one works on being a good teacher. I'm just talking about evidence that one is effective at a martial art or as a martial art instructor.
For example: should one necessarily have reached shodan or higher? Or is it just a "nice to have"? I realize one can be a shodan and a lousy instructor, and one can be an effective instructor at brown belt or below. But does the lack of a black belt reduce one's credibility so low that one shouldn't even bother with a dojo without one?
What other credentials ought one to have? E.g., experience as a grader in others' belt tests? I can't think of a lot of examples here.
And what non-credentialed experience should one have? X number of seminars attended, for example, or trained under X number of different people?
A different way to ask the question is...if I hope to open a dojo someday, what does the path from zero to dojo need to include, and what should I pick up along the way if I can?
Thanks in advance.
