(clears throut angrely) The 16 year old is anouyed!!! Lets set some ground rules (as the undeserving see's it). A black belt is just a peice of cloth, it is a symbol. Period. It is a symbol of of knowledge, understnading, and time in the style. However, the young should not be black belts. The rank/symbol/cloth strip around the waist also symbolizes that the wearer is capable of teaching. A four year cann't (probabaly) teach worth beans. But a sixteen year old might be able. And if not, then someone should email my sensei and tell him that one of the assistent sensei's (who has been teaching since he was sixteen) shouldn't have been teaching. And for that matter neither should I.
Yes many kids are unable (or unwilling) to teach or perform anyother duty expected of the wearer of a black belt. But I know a 6th degree black belt that shouldn't be teaching, and he's in his 30's!!!!! Basing things on age is pointless. It's like saying that I'm unable to do something now, but tomorrow i will magicly be fully able. It makes no sense. Yes there should be a general guide line based on age, but the bulk of it should be based on maturity.
As my understanding of a Black belt seems to be quite different from everyone here I find some interesting concepts in your logic.
Your comments touch on some tangeble and intangeble items.
You say, "The rank/symbol/cloth strip around the waist also symbolizes that the wearer is capable of teaching."
So you base some of your judgement on the ability to teach.
Is this mearly your concept? Your schools? Your organizations?
And if it is that important wouldn't your requirements/curriculum (of you/your school/your organization) make sure these items were met if you were to promote someone?
Secondly you say, "...Yes there should be a general guide line based on age, but the bulk of it should be based on maturity"
I find this interesting as many students as well as high ranks think it is their god given right to be promoted because they have been around X days working out (Even more amaziang are those without and instructor)
In the orient you are not considered an adult until 40!
A vast majority of schools only base testing/promotions on things like physical ability and time (which I think is only half of what we should be doing)
So my question is: How do you teach (and more importantly) test a students maturity in your class?
I find that trying to draw a concrete line in the sand will only cause you ten-fold more problems as you are trying to do.
