I love all the feed back its really awsome to know you can ask a serious question and get diffrent answers with out causing a war. And just to let everyone know I do read each and every reply that is posted. Everyone has some good valid reasons and some awsome points on the matter. I have asked this question over and over again to diffrent people even people not into martial arts and gotten similar responses. As for me I got a BB at a young age and to be totally honest I worked hard for it. Some say this is a question of maturity and like most of you said I too have seen adults at age 40 not be as mature as a 12 year old. So why give a 40 year old a BB and not the 12 year old. Which brings me to my next question what does a black belt mean to you? Better yet if they are given out like toys does it really mean anything? Any average joe blow can go out and buy a black belt but it doesnt make him a black belt. I guess the point I'm trying to make is you can pass a child off as a black belt but it doesnt make that child a black belt. I think if an instructor honestly has passed a student that is not deserving then maybe he is in his profession for the wrong reason.
I've never said, and I've never meant to imply that child black belts don't work hard for their belts. Many of them train quite hard, and very seriously.
As I said -- to me a black belt recognizes skill level and technical understanding, as well as some maturity. I won't recommend someone for black belt, no matter how skilled they are, if I don't feel that their conduct will be, overall, a good example for underbelts. I've declined to recommend at least one person, and held off on a few others. And I've been let down by at least one whom I did recommend... It'd be nice to see him again, since we haven't seen him since shortly after he got promoted. (And if you happen to recognize yourself in this... Get in touch with your teachers, whoever they may be!)
The simple truth is that a black belt doesn't know anything more the day after they were promoted than the day before. That belt doesn't convey any special ability; I know some underbelts who are much better at explaining and teaching concepts than I am, for example. I look for not only skill, not only understanding, but something that goes deeper; I guess you can call it commitment or dedication. If the black belt is the goal in and of itself -- than I feel that the person isn't training, within our system, for the right reasons. A black belt is also a responsibility to help pass on what you've learned, within our system. (Note that I am constantly qualifying this with phrases like "within our system"; more on that in just a moment.) Perhaps that's by teaching a club of your own somewhere -- or perhaps it's simply by training hard and regularly taking part in the club you came up in, and being a good example of a student for under belts.
But -- the ultimate thing is that there is no one definition of "black belt", except to say "a piece of material, black in color, used to hold the pants up or the jacket closed." One system may say that a black belt is a teacher, while another says that a black belt is just someone who's finally ready to start learning; teaching licence is another thing entirely there. Another may say that you must have a competitive record showing a certain number of wins to be a black belt, while others simply require that you have competed regularly over the past year. Some require several hundred hours of training, and others require several thousand hours of training to even be considered for a black belt. So, in the end, the question of "what is a black belt" really becomes "what does a black belt mean, within the context of a particular system under a certain instructor, to a specific person?" There's just no one answer...
