I remember backs years ago when my husband got his first degree black belt... eons... the fighting was the easy part! There were 6 fights plus a multiple opponent fight. But then beside all the katas and forms (we trained in both Shaolin Kung Fu and Koeikan) There were essays, "The Social Influence on the Individual in Our Culture" "The Difference between Koeikan Ken Do Gaku and other styles" Plus there were 5 books that had to be read with reports and tests. And I think it was for the 2nd degree you have to also learn Yang Tai-Chi Chuan long form, 2 weapons fights, and a huge paper on human anatomy including all the different structures and systems, bone, muscle, lymphatic, nervous, circulatory, and demonstrate techniques for attacking different systems. Then i don't remember at which level he had to design his own system as Master Jules mentioned. This was where the master was preparing the student to become a master of his own school. Many years later after we had moved across the state, he did start his own school. The reason I had found this message board, I googled my husbands name and someone on the board was asking about him. There were also age requirements and time requirements between each belt, although I think the rules were bent a bit on that seeings how my husband practically grew up there, helped build the dojo itself and his master even married us. 5th degree the age requirement was 30, but we moved away at 27, so I know that rule was bent! I know in our school you can't even get a black belt until age 18, the kids all have white belt with colored stripes when white with a black stripe is reached and they are at least 12 they can test for a yellow and join the adult class at 13.
