Overview: A Purple Belt in Jiu-Jitsu is about the equivalent of a Black Belt in most martial arts. I could go into more detail but suffice it to say, at this level you should really begin to expand your Jiu-Jitsu understanding. Choose areas to work on and master those areas. Help lower ranked students, at this level your ability to coach and help others succeed becomes more and more important. Teaching is the second highest level of learning, second only to application. So, if you haven't already, volunteer to help with some of the lower classes. Don't neglect the basics or Jiu-Jitsu's application to self-defense, but really begin to master elements that will bring you the most success.
Stripes: For Blue Belt and beyond each stripe is earned by accumulating 10 points in competition. Points are based off of placing first in competition, and by successful submissions in competition.
