Ranking

Technical knowledge is judged by the number of techniques a person can perform, and the level of skill with which he performs them. Competitions play an important role in the grading, allowing an instructor to compare the level of his students against those of the others in other schools. The high level of competition between schools is considered to be one of the key factors preventing instructors from lowering standards or allowing people to buy their way up the belts.

Many instructors also take into consideration the personality and behavior outside of class, and may refuse to promote someone if they exhibit antisocial or destructive tendencies. It is by these and other criteria that most instructors promote their students. A few schools also have formal testing, including oral or written exams.
