As such, what I don't get is why lots of dojos make a big deal about promoting a student from brown to black (assuming that they're training in a system where black is right after brown.) As I said its just one belt up so I don't see the point in making it proportionally much harder to go from brown to black than to go up any of the other earlier belts. JR137 I believe mentioned something about his dojo being a bit like that and it would be interesting to read what he has to say about it if he responds to this thread. He has made some good contributions.
Not quoted, yet I agree with it - there's nothing magical nor mystical about a black belt.
My former school and current school do make black belt tests much harder than the rest. That's all I know, and I like that approach.
Yes, black is literally the next color after brown (or whatever color a particular system uses; I think most TKD schools use red), but there's a big difference between what's expected from a black belt and a colored belt student. Not in a bad way, but colored belts tend to be promoted when they're good enough (relatively speaking). Black belts are held to a much higher standard in this regard. People routinely fail black belt tests. A classmate I'm close to promoted to 1st dan about 6 months ago. Out of approximately 30 candidates from various dojos, I think 22 were promoted. They weren't called out publicly, but after each night, there were less people the next session. They were taken aside at the end of the session and told behind closed doors they needed more time before they tested again. My CI has never had anyone fail a black belt test in his 30+ years teaching. Keep in mind it's the head of the organization doing the testing, not him. He's there to assist his teacher and support his students.
Black belts are expected to be leaders or role models. They set the tone in class, and they're expected to help people below them. They're supposed to have a quiet dignity about them, and not a "look at me" mentality. While they're not experts, they are a lot closer to it than the beginners are; they should be able to easily explain and/or demonstrate stuff to people below them. Not in a running a class sense, but in a helping students out sense and being someone lower ranks can look at if they're stuck during class.
Failing a colored belt test is quite rare, failing a black belt test happens more than often enough to say it happens. But just like testing for a colored belt, black belt candidates are invited to test when their CI feels they're ready and not when the student feels they're ready (although a student can respectfully decline taking the test).
I know, 1st dan is just one step up from brown belt, but it's a big step. It's hard to put into words, but if you were a student at our dojo, you'd understand. It's a cultural thing I guess. Not that what we do is inherently better not worse than what anyone else does (so long as they're not just handed out to anyone who's paid).
A black belt is someone the lower ranks are supposed to look up to. Not from a guru standpoint, but from a knowledge and technique standpoint. You've got to prove you're worthy. Some believe in a demanding physical test, others believe that the test is every minute you're on the floor. Both are correct, and even in dojos with rigorous black belt tests, you still have to earn the invitation to test. I prefer the hard test personally, but again, it's all I know.
