My opinion of kids, especially young kids in MA is they really aren’t there to be taught textbook MA techniques. Sure that’s a great goal and people think they should be, but there’s a lot of room for “good enough” in technique. The goal for kids should be getting them to love MA training and laying down a good foundation for when they’re older. No matter what you do, a 5 year old isn’t going to learn the motor movement at a level that kids several years older and/or adults are. You may see some kid online who’s performing stuff sharper than most adults, but that’s really an exception. Keeping that in mind, it ties into what’s previously been said about belts.
Do you have any MA experience specifically? Just looking at technique and nothing else, do you know what constitutes good TKD technique? Do you know exactly what to look for? I don’t mean this in a derogatory way. I’ve played sports all my life and teach physical education. I have no Brazilian Jujitsu (BJJ) experience, but I’ve got extensive wrestling experience. Watching BJJ, I honestly wouldn’t be able to evaluate a BJJ guy’s technical skills and determine if that guy should be promoted or not, even though there are some superficial carryovers to wrestling. I have no idea what a BJJ teacher is truly looking for.
When I was working as a Division 1 athletic trainer (sports medicine), I saw guys get drafted over guys who I thought were better. One day there was a pro scout looking to sign one of our pitchers. We had two field players who were phenomenal and to everyone on the outside, it would seem logical that they’d get drafted first. So I asked the guy why (he was a good guy who I had a decent rapport with). He said he initially came to see those guys due to their stats. One guy who was our career homerun record holder’s swing was awful for the next level. He was too good for the current level, but at the next level he wouldn’t get a hit. Great fielder though. The other guy was quite good, but lost a step from when he had knee surgery and he thought it was obvious that he wouldn’t get it back as it had been long enough. The homerun guy got signed to a very low level minor league team. He played 20 games; zero hits. I guess the expert knew his stuff
It’s all good, as that guy went to law school and opened up his own practice about 20 minutes away.
You sent your kid there because you saw some level of expertise in their teaching (hopefully you saw them teach first). Allow them to be the experts. That doesn’t mean don’t advocate for your kid; it means they know TKD better than you. Just as coaches rightfully get funny about “why isn’t my kid playing; he’s better than that kid?” MA instructors will get funny about “why isn’t my kid getting promoted; he’s better than that kid?” It’s the same thing.
Speak to them privately and ask what your kid needs to work on to promote. Don’t compare yours to anyone else’s. He’s not competing for playing time, obviously. He’s not going to sit out if he doesn’t promote soon. Would you rather him be given something for the wrong reasons or for the right reasons? Having an almost 6 year old and an 8 year old, I know it’s impossible to have them truly understand why others are promoting and they aren’t. I’m sure he’s frustrated by it if he knows they did and he didn’t. All I can say is tell him how everyone’s different and some people get belts sooner and others get belts slower. Tell him other kids will take longer than him. Tell him he’s doing a great job and keep up the hard work. Take the emphasis off the belt and put it on the process.
If you’re competitive and so is he, keep in mind he’s not competing against anyone but himself. He should be pushing to be better than he currently is, not better than the other kids. Trust me, they’ve all got their own strengths and weaknesses they need to address too.
