I don't feel like my 4th degree showed much more skill than my 3rd degree test, it just showed that I could memorize more things.
A 9th Dan once told me his view of the black belt ranks as follows:
- 1st-3rd Skill building ranks
- 4th-6th Instructor ranks for knowledge building
- 7th+ Master ranks
He believed that there was little use in someone advancing past 3rd Dan unless they were teaching others, building schools, or otherwise contributing to advancing the art to others.
While I don't subscribe to that entirely, it does make some sense.
Those in my network of schools all generally take 5+ years for students to reach 1st Dan, and do not use the title or master until 6th Dan, and Grandmaster is exclusively for 9th Dans.
Your comment that your 4th Dan test was mostly just about showing that you could memorize more things, is exactly the example of why TKD rank tends to be looked down on through the rest of the martial arts world.
Too many have confused complexity with advanced skill or understanding.
These are folks with 25+ years of experience in the art. They've been black belts in BJJ longer than some BJJ black belts have been doing BJJ. They've held the Professor for over a decade. Some of them have been world champions or at least medaled in worlds. And yet they're still learning.
This is why BJJ is beating many traditional martial arts. So many TMA instructors will not even spar with their students. They try to maintain some mystique around their skills by never putting themselves in a position where a student might catch them and bruise their egos. This, while BJJ instructors are constantly trying to improve themselves.
Just like TKD, there really aren't any "new" moves to learn after black belt in either art, just more advanced understanding of application or variations of principles.
The problem is TKDs schools often only look for a new checkbox to complete to say that they've 'learned a new thing'. This results in endless memorizing of pre-set combos that do nothing to advance true understanding or practical mastery.
They need to take a page from BJJ, in how they just always try to learn a new trick that helps them apply what is already part of their skill set.
Even in patterns, there really are not new moves (outside a few esoteric ones), just different movement lessons to learn. For instance, in the Chang Hon patterns system, 95% of all the stances in the black belt forms are the same 3 stances we teach to white belts (forward, back-L, and horse stances).
There are no new types of kicks that the practitioner hasn't learned long ago. The point of the black belt patterns is to focus on more advanced ways of generating power, transition between movements more efficiently and with better balance, etc. A couple examples:
- Po-Eun at 1st Dan teaches maintaining alignment while moving laterally between stances.
- Moon-Moo at 4th Dan focuses on balancing while performing slow, controlled kicks from various angles.
- So-San at 5th Dan works on balancing shifting from new angles (not new stances, just new ways of moving between them).
Anyway, that's my rant. TKD is already built to focus on the right things after black belt, just like BJJ. It's just to many haven't understood that more memorizing does not mean more understanding and they've invented hundreds of ways to make it appear that they've learned something new, rather than just work on better understanding what they already have.
