TKD is not a small family Kung-Fu style or a style dictated by old fuedal ways of doing things. I can only really speak about Ch'ang hon TKD, but ALL the orgs are teaching variations of Ch'ang Hon TKD, not their own versions... therefore, which ever org you grade under, you grade Ch'ang Hon TKD eg. Ch'ang Hon TKD under the TAGB, or Ch'ang Hon TKD under the ITF etc. When someone leaves they no longer mention the org (except in their history), they would say I'm a 4thh degree in Ch'ang hon TKD, not ITF Ch'ang Hon TKD or TAGB Ch'ang Hon TKD... EVERY ITF based organisation are teaching the same thing with an Organisational slant on it but they are not the art!You retain the knowledge, and you can belt a person in "your" art, but you can no longer belt in that Organization's or Master's name.
As for examiners, most orgs are done by a) A panel with a Chief instructor heading it OR b) A Chief Instructor.. either way, you can still say you were graded by Master So & So (if you were) as it is true. Very few students are directly training under the Chief Instructor/Master of an org!
Again, you learn and grade Ch'ang Hon TKD.. you cannot be stripped of that knowledge or skill, just the standing within the org.. in the old days of fuedal Japan taking away a licence meant something.. but this is not those days - things do not work like that anymore.You are typically stripped, by them, of that ability.
In Ch'ang you grade up to 6th degree as a physical grading. After that they are either a) time served or b) Time served plus promotion of the art .. (something solo instructors rarely get as its organisations that give these!)In TKD, you are graded on the physical up to 4th Dan
You can state you do KKW TKD as that is the STYLE you learnt, you can also say you do Ch'ang hon TKD, as that is the style you learnt... neither WTF or ITF are styles, they are simply organisations and when soemone leaves them.. why would they state they are still with them?You can still say you are TKD, but that you are not belting in say Kukkiwon (SP?) or WTF, or ATA, or ... just in TKD "standard" or TKD "You".
Those that say they do WTF/ITF TKD are using incorrect terms.. but unfortunatly the terms have become common usage to denote a style of TKD..so people accept & understand them even though thye are actually incorrect and can be confusing for some. Some may even say ITF Style or WTF Style to diffieniate between the style and actually being part of the org.
The ITF and WTF are not Kwans.. Oh Do kwan was the Kwan.. it no longer exsists.. most of the other Kwans merged to form the KKW/WTF.. they no longer exsist as kwons anymore. there are a few kwans about and going between a Ch'ang Hon org/a KKW org or a Kwon is similar to changing styles (aka. going from TKD to Wing chun) and hence a grading is enevitable.. but going from one KKW group to another, it is not and it would just be money making to ask them to do so, unless they were exceptionally poor from their former clubs teaching methods!If that person you belted to say 3rd Dan wanted to go to Kwon events and get recognized as a 3rd Dan and wanted to belt someone at 1st Dan, under Kwon (unless they changed their ways recently) would have to test (and pay said fees) at 1st Dan, 2nd Dan and 3rd Dan to get Kwon. 3rd Dan.
