We do the same as most BJJ schools...yellow, orange, green, blue...blue is like adult blue so, must be 16 to earn that. You can give out belts and do stripes or ...I do patches and T-shirts

There seems to be a cross over more with kids ranks to no gi like: white is beginner, yellow intermediate and orange and green advanced so be aware how you rank eps. for the kids that compete. right now the highest ranking kid is either Tory Davila or Julian Garcia as far as I know.
You guys got some rug rats training?
If you have any more questions regarding kids stuff let me know

Thanks
