The concept of a written exam has been incorporated into the Dan exams of the Internation Tangsoodo Alliance since it's inception. The written exam is quite extensive and often includes Essay questions. Most Shimsanim require the candidate to also write prior to the exam an essay on an assigned subject. I personally have assigned a book to be read and subsequent report to be written on every occasion where I have served as either Mentor or as Shimsa. When I was coming up through the ranks, this was a demand I placed upon myself without being told so by my mentors. In Korea, origianlly there were no such requirements, atleast not up to the 4th Dan. This seems to be an innovation that was first established in the west. As regards TKD today, you simply cannot get a job teaching in Korea unless you have been educated and earned an academic degree, preferably from one of the Universities offering specific programs in Taekwondo. There has been a great debate in this country (USA) over the establishment of some type of licensing for MA instructors. Most are against this. I am one of the few who do not think it would be a bad thing....even if it means I couldn't teach anymore. I think it will be impossible for us to ever raise MA out of the murk of being something carnival until this happens. I also find it deplorable the great number of martial artists who still believe it is unimportant to know the history, culture, politics and language of the Asian Martial Arts. Sadly, more would keep us ignorant than push us to excellance. THe only reason I can find for this is because it serves their own greed and self gratification. It may no be in the keeping of the spirit of humility for one to confront such people publicly...but unfortunately, that currently is the only method by which they can be revealed and rebuked. True teachers should never fear challenge.
