Maturation

In Taekwondo, higher belt ranks require more time before testing because students need a period of maturation.  As techniques mature, so does the student's thinking.  The deeper understanding gained through training and reflection allows philosophy to become a meaningful part of personal growth.  Therefore, advancement is measured not only by technical skill but also by the development of character, judgement, and wisdom.
