In most arts, you'd need many years of training to be able to teach them. I'm only passingly familiar with Krav Maga, but I think part of the original point of it was that there was a fairly limited syllabus, so only a few things to really learn. So, for comparison, in the core of NGA there are 50 different techniques, and students typically learn between 3 and 40 applications per technique. Add to that all the non-core material (groundwork, etc.) and variations on the techniques, and you can see that there's a huge syllabus to learn before becoming an instructor. A shorter syllabus should allow quicker assimilation. If you took someone with a good background in similar techniques and passed them a fairly short syllabus, I think it wouldn't be unreasonable to have them certified as an instructor after a course like that. However, if their background doesn't include very similar techniques, they're likely to miss the principles behind some of them, and teach them ineffectively.Thanks for finding that. It looks like takes a combined total of 156 hours of testing (21 days at 8 hours a day). Real question here: What's it take to be able to teach in most martial arts? I've mostly trained in MMA, and I never gave it much thought as long as the instructors knew a lot more than me I was happy. That seems like a lot to me, but what's it take in Kenpo, Hapkido, etc?
