When the student walks in the door, the training starts. But the education is in bits and pieces. A lot of pieces at the beginning and as skills are acquired more and more, they start coming together. Black belt is when the student really is tested on what you know of the basics, what you can do at that level in your training. It is at least in my school. We don't have ki training but I do believe there is a spiritual training to become a true martial artist. All the learned patience, repetition, discipline and perseverance builds indomitable spirit. It builds a "I can do it" attitude and the "I cannot be defeated by myself" attitude. And also the attitude needed for defense-to overcome adversity. It is a slow strengthening of the spirit.
Some need to learn self control (anger, bragging, force) or do not make it to black belt. Those that cheat or lie even by not doing the number of kicks or not doing them to the best of their ability, either learn they are cheating themselves or wonder why the training is not working. They hardly come to class, but they are the student that wants to test for each belt with little skill, little patience learned to do form, and not much endurance.
So it builds integrity in that way. If a student quits early at kicks, how could he later be relied on as a black belt to be there to open the school and teach class? Such a small thing shows true character. All these small things build to the culmination of the black belt test and beyond.
But while the test is a marker in the development of a martial artist, it is not the end of learning as so many colored belts come to believe. Then the student begins to realize as a black belt what he/she does not know fills alot more years than what he has just completed. But, I believe it is a true beginning in his awareness of his spirit and journey in his martial art. TW
