Absolutely not. Any competitor 16 years or older may compete in the Adult division. That's an open-age division.
Only competitors who are 30 years or older on the day of the tournament may compete in Masters, but they may compete in Adult instead (not both).
Only competitors who are 40 years or older on the day of the tournament may compete in Adult, but they may compete in Masters or Adult instead (not both).
We do not currently offer Masters or Executive divisions for any brown or black belts. Not all tournaments offer Executive divisions.
