Last year, our master instituted recertification tests for all black belts. We are required to test every 6 months. Mostly this is for the black belts who do not try to work on stuff, do not attend many classes, etc. This test for us includes forms- poomse (Taekwondo), pushups, punches, kicks, slow motion kicks, self defense, sparring, a breaking contest to "wow" the master, even grading on integrity etc. What is your experience with this and is it working?
