Certification for instructors

Over the past couple of years I have watched various instuctors teaching others
Most teaching is for our state Colorado CCW requirment.
I have seen everthing from todays bad guy target at 3 yards with laser grips to shooting off sand bags at bulleye targets at 15 yards.
I'm a gunsmith college graduate, ex USAMU gunsmith, infantry master gunner and I've been messing in various forms of burning up powder, PPC, bowling pins, metalic, Bulleye, steel shoots and early forms of practical pistol competition.
My thought is make the instruction fun, challenging and rewarding for the student. Hopefully teaching some good fundamentals with the goal that the student will continue there shooting for fun and develop confidence for their self defence.
I'm thinking about getting certified with the NRA to teach such classes.
My thought is its more important to teach some basics skills and avoid bad habits then to start on some point and shoot drills such as I saw today.
I'm I wrong to make the training less realistic, less defense weighted, and make it more enjoyable with the thought that the student will continue to seek others forms of competion to develop there skill.
I'm trying to get the next person interested in getting a CCW involved in the shooting sports, and not just pass some state mandated skills.
I'm open to ideas.

I think that there has to be quite a bit of realism in order to teach proper safety. Its fun, but its not a child's game. I think that there are many aspects to shooting, but the two main aspects as far as I can see are defense and sport. I personally believe that defense is much more important and if I'm ever trying to "sell" the idea of shooting, thats my first and strongest claim. There's no reason to hook people and reel them into shooting. Either they see the value or they don't. You can try to explain it to them from your point of view. If they accept it, it means that you taught them something. If they don't, you either weren't clear or they just don't care. Not everyone's gonna be a shooter.

NRA Instructon certification will certainly be valuable in setting yourself up as a formal instructor. But the NRA stuff is really at a pretty elementary level and without a lot of flexibility. What you are talking about is some ways more advanced and with a different slant. The NRA sheepskin will mostly be for advertising and credentialism.

My thought is the NRA certification is only to meet the state mandates.
I want to get new shooters interested in continuing there education.

The vast majority of what the NRA teaches is the basics and these will set the foundation for you. Anyone who claims they are too low spped for them will not be a very good instructor. You need to know what the basics are and be able to teach them to someone who knows very little, or nothign at all about firearms.

You know the old saying, "you need to learn how to crawl before you can walk".
