Take great care which school of karate he goes to regradless of style ,they may call it shotokan karate but quality of instruction is very important .... I saw the video .....don't worry about how long it takes for a black belt ,learning in a good club something of quality is far more important . Are you saying it doesn't look correct in the video? I have heard that some schools pretty much just hand out belts. I was concerned, but actually, this is the only school within 50 miles of us. She has had students win medals with the USA Karate Team , which makes me more confident about the school. I know a few of the older students have won tournaments here and in other countries. Like I said, I know next to nothing about Karate so I'd like to hear people's opinions.
