Correction. I went back and found the details. The instructor is Klay Pittman. He is a legitimate 3rd degree BB under Carlos Machado. The belts are considered to be in BJJ, but the kids get "junior black belts" and get a stripe on the belt for every 200 hours on the mats in rank. One of his kids has actually been promoted to 7th-degree "junior" black belt.It's actually already happened. There's an instructor (in Texas, if I remember correctly) who is a legitimate black belt under the Machados who has created his own curriculum with quick promotions and high black belt ranks for kids. Technically, the ranks are for his own in-house grappling system, not BJJ, but he has nevertheless gotten very negative reactions from the rest of the BJJ community and those ranks are not transferrable anywhere else.
The rest of the BJJ world does not approve of "junior black belts" and have in general been very critical of the idea.
