Yes, it is, IF they are a reasonable proficiency, and meet all the non-arbitrary requirements.
Ok, so going on this, if there should be no standard, and the person should be able to test, then realistically, you could have a 10th degree BB who isn't even 40yrs old. I dont know, maybe its just me, but I always picture someone who is a GM, as an older person, not younger.
If that is your requirement for a grading then they are capable. That is the argument there, make the grading requirement understanding and ability to teach if that's what you want BBs to do, not make the age 18 and hope they have those qualities just because they're a certain age.
So a 10yo 3rd degree BB is going to have the same understanding as a 35yo 3rd degree?
Ask those questions in the grading, don't assume they know them because they are older. Again I said base it on quality not on age and you go straight back to quality.
Because common sense should tell you that a child is not going to understand something the way an adult will. Lets use school as another example. If the child doesnt know basic math, how the hell are they going to know algebra? Trig? Calc? When a child is learning to write, don't they learn the letters, first, how to spell, link them together, etc., before asking them to write an essay paper?
Please read what I am actually writing. This is the guy who knows the material and you say things like this makes me think you barely skimmed over what I wrote. He didn't expect to grade, he was just ready to grade, we didn't mention his caring of whether he was moving up or not, more that a student will lose enthusiasm because of an arbitrary barrier.
I'm getting the impression that you're getting upset. Is this perhaps because you are against what I, and a few others are saying, because perhaps you fall into the category that I'm talking about? Maybe you do, maybe you dont, I dont know, but you seem very aggitated. Oh well...back to the thread. Regarding what you just said. Lets break this down:
In response to something Jenna said, I replied:
"As for damping the enthusiasm...you explain to the child why he/she was held back. I'm doing my part, which is to teach. They need to do their part and practice."
to which you said:
"I think (correct me if I'm wrong) that by dampening the enthusiasm was actually for the more gifted child (Joey), not the one who didn't work hard (Jack). So the reason you'd be explaining to him would be along the lines of "You've put in the hard work, you know all your material, you're enthusiastic, but the people who made the requirements said 18 years old is the requirement and it's 3 months till your birthday, so no grading"
I then replied:
"In a nutshell, yes, they wait. All of this, of course, should be told to the parents, child, adult student, in the beginning. Personally, I don't think that anyone should expect rank. If/when it happens, it happens, period. Like I said earlier, people are more concerned with whats around their waist, instead of making sure that they look sharp, can perform, can perform under stress, can adapt to whats presented to them without thinking. In the end, its the skill, not the belt that is going to save their butt, when the poop hits the fan.

I dont care if you have 30 stripes, if you can't do the material, because you were in a rush to get the next belt, not only did you get your *** kicked, but you wasted all that time training."
I feel that during the initial sign-up phase, how testing works needs to be explained. I've been teaching for quite some time, and I've had many people, kids, adults, and parents, all ask about the testing, when they may be ready, etc. In many schools, there is somewhat of a timeframe, a basic idea to give. Ex: It should take 3 mos to go from white to yellow. That doesnt mean the person will be ready to test. Yet its assumed by many that they will be. The gifted child may be ready in 2mos, but if the standard is 3, then he/she waits.
This is probably why I'm not crazy about kids as young as 3 and 4, joining up. However, for those that do have a 16yo requirement for BB, do those schools allow 4yr olds to join? If so, I'm sure, they don't allow them to test so fast that they're 10 and ready for black. Some give a Jr. BB instead. They're still learning, have something that gives them the drive to continue to train hard, and when they're old enough, they take the adult BB test. I'd much rather see that, the Jr. BB, instead of a 12yo 2nd degree running around. I know the JRBB isn't on everybodies top 10 fav. list of things.
Everyone looks forward to getting a promotion, even in the real world. But, nothing should be expected. And if you stop and think about it, there should be no issue with the gifted child having to wait another 3mos, due to the fact that if they were really examined like they should be, prior to testing, I'm sure there may be something that could use polish. I've had people perform just fine under no stress, yet, when they know they're really being looked at, they start to crumble. When the attack is loose and relaxed, they do the tech. just fine, yet when the punch is really coming and if they don't move, they're gonna get hit, they crumble.
There are ways to slow people down. If you haven't figured out what they are, I dont know what to say. Its one thing to just run thru the material from A-Z, but when you really get to the meat of whats involved, it shouldn't be that simple.
