Earning rank in Brazilian Jiu Jitsu is perhaps harder to do than in any other martial art. It’s no secret that jiu jitsu black belts are considered to be among the toughest members of the fighting community, having put in thousands of hours over the years to obtain the rank. What’s not always as clear, however, is what criteria needs to be met to be considered a black belt, or any of the other ranks in jiu jitsu. That’s because there’s no clear cut system of moves defined per belt level like in other martial arts. Jiu jitsu has no katas, and most schools don’t do belt tests, it’s left to the discretion of the instructor.
Brazilian Jiu Jitsu’s belt ranking system used to be differentiated from Judo in that BJJ belts originally consisted of only 3: white, light blue for instructors and dark blue for head instructors. According to Professor Pedro Valente, the belt system of Judo was adopted by Elcio Leal Binda when he created the Brazilian Jiu Jitsu Federation in 1967. What’s unclear to me though is how that evolved into the current jiu jitsu belt system, as the judo belts are different than Brazilian jiu jitsu belts today. It sounds like the idea of different belts differentiating fighting skill may have been adapted from judo, but the actual colors/degrees of the belts were specific to jiu jitsu. If I find out for sure I’ll update this post.
