As i am a JKD practitioner we dont really have a grading system, but we test ourselves against other fighters that are meant to be better showing if we have progressed or not. Also in tournaments we dont go into categories you just fight who you are drawn against.

My question is, Do you think all martial arts should be graded this way by your progression being shown in the technique you posse and not wat belt you own? or Do you think that belts have become a target to aim for and as soon as this level of skill has been achieved the feeling for martial arts starts to die out as you think you have gained your goal?
