We have 3 (well two are 11) at our school alone that meet these requirements. And they are all pooms at this time.This is my opinion regarding black belt standards for ten and under.
1. Crisp performance of each form with power and snap.
2. Ability to perform the techniques of the curriculum with power and snap, both solo, in step sparring, and in free sparring (to the extent that the sparring rules allow).
3. Mature enough that you would think that the kid is at least fifteen in the dojo.
4. The ability to "defend themselves" against an adult attacker. I do not mean the ability to beat an adult attacker. But to use their techniques in a way so as to escape or ward off an adult attacker. This should be demonstrated with an adult student or instructor standing in as the adult attacker and not just giving it up for the kid.
5. The ability to transmit technique to an underbelt of any age. I do not mean take the class by themselves. But if I go into a school as a white belt at age 42, a ten year old black belt should be able to demonstrate a turning kick, break down how to properly perform it, and tell me if I am doing it correctly, as well as give me pointers as to how to improve it.
6. Be able to spar at an adult black belt level in terms of execution when sparring kids their own age and should be able to at least handle themselves in sparring with an adult black belt student.
7. For breaking requirements, they need to break the same number and thickness of boards that the adult black belts do.

I can also tell you that many of the adults hated testing with them, as they made most of the adults look really bad as far as techniques were concerned.
