Only if they are Kukkiwon. Other orgs handle youth ranks differently.True but we should clear up one technical point. A Black Belt under 15 years of age is a Poom holder. Not a Dan. It does transfer over but technically thats a true point to make.
The only thing that kiddie black belts have to do with this discussion is that it attracts more kids and thus more parents, and thus more difficult parents due to the law of averages.
Otherwise, I do not care about whether or not schools put black pieces of cloth on children. I have voiced my opinion about youth BB's on the youth BB thread.
