At what Dan grade does everyone reckon you should start running your own class?
I agree with the general consensus here. Geup levels, and Dan ranks are measurements of a person's technical skills. Teaching is a separate issue that requires special training above and beyond rank. While they are separate, one is dependant on the other. A person can not teach what they do not know, thus they must reach a certain level of proficiency before they can share that knowledge with others.
Beginner students (the first few grades: 9th, 8th, 7th) have not ironed out the wrinkles in their own skills, and often do not fully understand what they are doing. Once a student has promoted to their first rank level (ie: yellow belt), they can help a lower rank (white belt) to remember what the teacher has already shown them.
Middle rank students (6th, 5th, and 4th grades) often make good class leaders (not teachers yet), and they can help lead warm up exercises, and monitor a small group of students within a class that are working on a particular activity while the certified instructor moves about the room from group to group. My policy is that these students are not ready to teach students new techniques that they have not first learned from a qualified instructor. These students are gradually learning how to run a class, so that they can make the transition to instructor "trainee" soon.
High rank students (3rd, 2nd, and 1st grade) are capable of teaching low and middle rank students new techniques, their new form, and one-step sparring concepts. This is usually done in pairs or small groups within the class, and while under the supervision of a certified instructor. I always require that a 1st Dan, certified instructor or higher, start the class, then turn over various portions of the teaching to high rank instructor trainees while they watch. Later, the high rank can be given pointers on what they need to do to improve their teaching skills.
I think that most new customers would not want to walk into a Martial Art school, and see the class being run by a child without an adult in sight, or by a color belt without a Black Belt in the room. I believe an instructor should be at least 1st Dan, and have proper "assistant instructor" training and certification before they run an entire class, from start to finish, by themselves, without supervision. A person who has "Instructor" certification can run all the classes on any given day without the Senior Instructor being present in the school, but this should not be a regular practice.
Just being a black belt (1st, 2nd, 3rd or even 4th Dan) is not enough to run a class. Minimum rank and understanding of techniques, and the curriculum is a prerequisite, but without special instructor training
and certification - - it is a "no-go" at my school.
Rank and teaching credentials are two different things! :mst:
