I'm a third Degree Black Belt School Owner in Taekwondo/Jujitsu. This answer is a simple one for me...... YES. Here is why..... In today's world, you see adds in magazines and newspapers all the time that sollicits "Be a Black Belt in 9 months". The rank behind the black belt only holds value to a few...... Example: I know many, many, many 4th and 5th and some 6th degree black belts who are Great Black Belts- Technique-wise, but they can not teach worth a flip!!! Some of them can't even speak good english! My point is this...... a student is only as good as his or her instructor's abliltiy to articulate his/her knowledge to the student. How many times have you heard martial arts students make comments about how their instructor can do this or their instructor can do that? Thats all fine and dandy but, what can your instructor teach YOU? One of my competitors went from a black belt 2nd degree to a 4th degree in 1 and 1/2 years. I was a 2nd degree with twice as many students with the same amount of years in the arts as my competitor and same amount of years teaching experience. Go Figure! My advice to you is this: When you get to the point in training where you are allowed to open your own school..... be honest and proud of your rank. Tell your students that what makes a good instructor is not the level of black belt..... its the instructor's ablility to communicate his knowledge to the student. Good luck!
