If it takes a year to get 1st, then my end number was correct even if my math was wrong
1 year per rank, per rank.
1 year from
1st to 2nd.
2 years from
2nd to 3rd. Minimum of 6 years from 1st to 4th.
The minimum time to get black belt varies. Most KKW schools I believe 2-3 years is common. Some schools are 1 year. This also assumes the student is not accelerated in some way. (I got mine in 23 months, despite it taking minimum 30 months at my school).
These are also just that:
minimums. For example, at my old school, the testing schedule was:
- 2 months minimum in-between each of 9 color belts (up to red), for a total of 18 months
- 4 months minimum for each of 3 red belt ranks, for a total of 12 months (30)
- Additional wait times based on when you started (i.e. if you started the week after February testing, you're not eligible for April testing, so you wait until June testing)
- Additional wait times based on when you got your "Jr. Black Belt" (highest red belt), if you got your Jr. Black Belt in February or August, you could test for black in June or December. If you got your Jr. Black Belt in April or October, you would have to wait 8 months for the next June or December testing in which you have 4 months. (Exceptions made for students who were moving, or who missed test due to injury).
Based on when you start, the minimum could actually be up to almost 36 months.
This also assumes students test every time they're ready. It was very common for young kids to miss 2-3 tests because they're not meeting attitude requirements. Or for adults to skip 1-2 tests because they want to make sure they have everything correct. A good rule of thumb is that students averaged a delay of 2 months per test, and ended up with around 3.5-4 years to get black belt. At least, students who were consistent in their training. Add in those who were inconsistent, and the average is probably 3-5 years.
The same thing happens after black belt as well. I would say that while 1 year is the minimum to go to 2nd dan, very few did it in a year. Mostly it was 1.5-2 years. 3rd dan was much rarer and it's hard to get an accurate picture. These are usually the most dedicated folks anyway, so it skews the results from what the average student is capable of.
I honestly don't think it's possible for someone to get 4th dan in my Master's system. The problem is it's entirely built on memorization, and even he doesn't remember the 3rd dan stuff, because there's so much of it and it's been a while since he's done it. (He even admitted to this). Of course, if he teaches you X one week, and expects Y the next week, it's
your fault for doing X instead of Y. It's one reason why I left, because I figured I was never going to be able to learn his stuff if I'm spending more time tracking changes, and then even on the test day I wouldn't trust that what I trained is what he wanted. This wasn't a problem at all for the kids curriculum through 1st dan (to get 2nd dan), and wasn't a problem 99% of the time for the remainder of the adult colored belt curriculum or the 2nd dan, but it was 50/50 with the 3rd dan stuff.
