Some of the things you listed are, IMO, completely tangental to decent instruction - that is, they can be done at schools with good or bad instruction. What they have in common is a focus on business and making money.
If they're doing aftercare in addition to teaching martial arts, that's a good revenue stream for the school. It may be compensating for a poor-quality martial arts program, and certainly could be causing the owner to prioritize the babysitting over teaching, but it's not necessarily incompatible with good instruction.
Where we're at, most families have both parents working, and the parents often can't bring the kids to class until after 6pm or sometimes even more like 7pm, so if a school picked kids up they could teach them much earlier in the day, and you'd have them coming to class every day. I think a school that offered good martial arts and aftercare could, theoretically, churn out some amazing students. I just wouldn't want to deal with the hassle of becoming a licensed childcare provider (which would require, among other things, building a playground in a back yard area and having a dedicated room...).
We do a parent's night out like that a few times a year, and both the parents and kids love it. If we had some more young, energetic staff members willing to sacrifice their Saturday nights for extra cash, I'd totally do one every month.
I'm not a fan of this used-car-salesman approach, but that's about business, rather than instruction.
This is really where the "poor instruction" starts. Not everyone is interested in, or cut out for, being an instructor. They should be training instructors and assistants specially. But plenty of instructors do this kind of thing, throwing anyone with a black belt in front of a class.
Are they all formal classes, or does the instructor break one class up into a few smaller groups to work on a specific activity, and assign an assistant to work with each group? That can be a good approach, and circulating between the groups makes sense then. But having a bunch of entirely different, unrelated childrens' classes going on at the same time in the same space is a recipe for chaos and disaster.
I’m not good at chopping up quotes, so bear with me...
The aftercare portion and even the business portion don’t automatically make the instruction poor. If my kids (5 and 7) were going to sit around somewhere until 6 pm-ish or even a traditional daycare, I’d much rather them go somewhere like the place I described. They get their homework done and have physical activity. It’s a win-win. I’m not knocking that, but just showing an overall trend developing for the big picture.
As to the money...
Everyone’s got a right to try to make a good living and however they choose to do so, except of course illegal stuff. The tuition is quite high. In fact, it may be the highest in the area. Value for money is a personal thing.
I have several issues with the money aspect though...
The black belt plan sounds great on paper. It costs $4k, with all testing fees including 1st dan included. You pay that price regardless of how long it takes. If it takes 5 years, you pay $4k total. If it takes 15 years, $4k total. If you pay it off and leave before black belt, you can come back whenever you want and don’t pay until you pass your black belt test. So you have a 5 year old who stays a year then quits. Then when he’s 15 he decides he wants to go back. It’s already paid for, so there’s no charge. and at the alleged average of 5-7 years, at 5 years it’s about $80 per month. The average commercial dojo in the area is $125-$150, so it’s a great deal. On paper.
Here’s where it falls flat - the real average is about 2 years. $4k for 2 years is almost $170 per month. And remember all the hidden fees - new uniforms, clubs, weapons, sparring gear, etc. that can only be bought in their shop. Everything has a logo on it. Everything.
Then there’s the requirement for teaching issue. If you’re regularly teaching, you should be compensated somehow. Free or discounted merchandise, free movie nights, free SOMETHING. Nope. The way I see it, it’s a way to maximize profits. Tell them it’s a requirement so you don’t have to pay more staff.
All students, regardless of age, have to sign up for the black belt plan. Is it really ethical to have a 5 year old in a multi-year contract? Enough said about that.
All would be excusable if the teaching was great. The classes aren’t structured as you theorized when I was there. They all bowed in together, then the various groups went their separate ways, seemingly separated by age. There were 14-16 year olds running their own groups, assisted by a 12 year old, if I had to guess ages. The two senior instructors didn’t teach anything. They circulated, but they weren’t telling the instructors what to teach, nor did I see them correct anything. And each group was doing their own thing. The floor was decent sized, but way too small for 4 groups of at least a dozen students each. I honestly had a headache from the noise level when I left, which as about a half hour into the 45 minute class. Not that I expected anyone to look razor sharp, but no one really looked very good.
I have no problem with a glorified daycare if that’s what they’re truly pushing. What I have a problem with is how they sell it as TKD and self defense first, and all that other stuff as an added bonus. In reality, the TKD is the added bonus, and the quality of it is pretty lackluster.
Everyone’s entitled to do what they think is right. Some of the kids and parents love it. They’ve got their reasons. I think it’s awful. I’ve got my reasons. A have a good relationship with several parents who send their kids there. Many say it’s a complete scam. Two have said they hold their kids back from promoting too soon so they can feel like they’re getting their money’s worth. I don’t blame them - they were told the $4k would be for an average of 5-7 years, and not even 2 years later they’re almost up for a new contract. One said their kid has no clue what he’s doing yet they’re telling him he’s great and he’s ready to test for his black belt.
It is what it is. What it is is definitely not anything I want for my family. To each their own.
