- Insight: In the best karate dojos in order to achieve the next belt you must defeat an opponent on that next level, ensuring that the promoted is never worse than the current group.
- Principle: Clearly define the responsibilities at each level and the skills required to perform.
- Principle: Clearly define a formal process for all promotions.
