How often should a student be allowed to test for their next belt rank?
More often then naught in a commercial dojo you are tested based on the number of days you are in attendance rather than how well you know the next belt testing requirements. I have personally witnessed an instructor show his students the promotion test requirements the first hour of class and then test them next hour of class. Even though his students were not able to perform the techniques adequately, and pass them to collect his testing fees.. Belt testing fees are a stable source of revenue for most commercial dojos. That is why they test their students on an attendance bases rather then how well they perform the techniques required for testing. WAA students test only when they have reached a level of proficiency with the techniques that are required for their next belt rank. There is a minimum time between belt rank testing. Not only that but we require them to be able to perform all of the past belt rank testing requirements as well.
