No matter what anyone says, it's all opinion. It's entirely up to the school where each person practices to determine the belt requirements for advancement.
No and yes.
No: If you are running a school that is associated with any organization, there are organizational requirements that are not a matter of opinion. The Kukkiwon requirements of both curriculum and age are spelled out in their bylaws. I posted a link to these much earlier in this thread.
Yes: it is up to the individual school to evaluate how well those requirements were met and to impose additional requirements.
Agree, don't agree... there is no right answer, just what you think the requirement should be, or what it is at your school.
What they should be: Proficiency in the curriculum set down by either the organization or dojo cho if it is an independent school. The ability to to effectively spar under the rule set of whatever organization their school is a part of. The ability to defend one's self reasonably well
using the style.
At my school: GM Kim grades the students on the base KKW material. They need to know all of their taegeuk poomsae, must demonstrated sparring proficiency in the WTF rule set, have a working knowledge of Korean terminology, and perform all of the hand and leg techniques in various stances. Four different breaks of GM Kim's choosing.
Our point of individualization is that the test is a very physical test. His main emphasis is on indomitable spirit and the student's mind. A full warmup complete with a ton of pushups are all a part of the test. 100 each of the basic kicks (front, turning, side, axe), 100 punches, an assorted number of blocks as he calls them out until he is satisfied. The student must also know all of the self defense techniques that he teaches in the class, which are drawn from hapkido (he is a former ROK Special Army HKD instructor). After all that, you spar four high belt/black belt students of varying sizes with no rest in between and then spar one of the instructors.
The poom belts are no exception to this. The only real difference is that they generally break thinner boards and generally spar kids in their age range. Exceptionally large kids will get the same boards and spar opponents that are more appropriately sized, usually teens.
TKD is so bastardized in America (overseas as well, and even somewhat in Korea) that it's impossible to set any type of "standardization" any longer.
In general? Within specific organizations? Bastardized in what way? Not that you are necesarily wrong, but that is a fairly sweeping statement.
I do not agree that any type of standardization is impossible: The Kukkiwon sets a curriculum standard. It is fairly brief in comparison to what it could be, so within a single org, yes, a standard of some kind can be set.
The school my son attends is run by a Grand Master who has over 50 years in TKD beginning in Korea, which is more time then many of you making comments have been alive.
Without trying to seem condescending, that is irrelevant to the discussion.
Grand masters of all ages have their own motivations and reasons for doing things. I have see high ranking GMs go from being total hard core to being belt factories as the years progress, putting belts on students who are an embarrasment to their school.
No, I am not saying that about yours; I do not know the man, so I would not make that assumption. Nor am I saying it about most. But it does happen. Ninth degree rank and age are no guarantee that the school is not a McDojo or that he is true to what the standards were envisioned to be when he began practicing.
I can say that Jhoon Rhee schools had very different standards of BB's when I studied under him in the seventies as compared to what the standards are now (whether or not that is good or bad is a different discussion). And that guy is a TKD institution!
In the end, GM's gotta eat. You would be surprised how quickly one compromises their lofty standards when they need to pay rent on the building.
Just like any other school, he has his requirements for BB's which everyone must abide by for promotion.
And your son met those requirements and thus is a BB in that school.
Same as I am a BB in my own school. If I head down to Twin Fist's school, they may decide that I am not up to their standards and I may not be able to wear my belt until I catch up on what they do.
