Exactly. Define black belt, and then we'll know if it's reasonable or not. Look, black belt is just a shorthand for some kind of standard. Some folks have loose standards, some don't. Some have clearly defined, measurable standards, and some don't. As I said earlier, in this case, we're talking about a specific TKD program, but we don't know much more than that.
So, the conversation briefly discussed the specific program, and I think most people ended up shrugging and saying... maybe? And then it moved on to a more hypothetical question: can you teach someone what they need to know in order to be a functional black belt in a 12 week intensive program? It depends on a few things. What are your standards for black belt (I don't believe everyone in this thread, much less the martial arts community at large can answer that question)? Are those standards clear and objectively measurable? Are they dependent on other prerequisite skills? Do you have a plan? Are you competent to pull this off?
In the broader sense, the thread moved on pretty quickly to whether a 12 week intensive program is a good way to teach people.
Does that help?
Totally agree. 3 months is a very long time to devote yourself to a single thing. You can make a lot of progress in that time.
If high level, well rounded ability is the standard, you're probably right. But it presumes that the program structure, standards, and quality of instruction are both roughly equal. As a counterpoint, I can easily envision a rank novice in a 3 month program outpacing a 3 year martial artist with equal hours. drop bear's school actually illustrates that very point.
I don't think I get the subtle difference here.
Only thing I disagree with here is the idea that 12 weeks is "such limited time.' It's definitely a fixed period of time, but as I and others have tried to point out with numerous examples, 3 months is plenty of time to teach a heck of a lot. Cops learn to be cops in just a little more time than this. College classes are often 12 weeks long. Literal boot camp is 12 weeks long. There is an entire industry of 12 weeks sports camps for young athletes. And in fact, the seasons for most sports is around 3 months long.
Don't get me wrong. It's not a limitless amount (obviously) and there is always more to learn. Rather, the point is it's plenty of time to see a lot of progress.
