SigLite:
Instructor yearly renewal is $5.00, or you can renew for three years at reduced cost. This is only to pay for processing the paperwork, so there is hardly a profit to be made here.
The various NRA training courses existed for over a hundred years prior to to the advent of CCW programs. This was not something instituted as an after-the-fact scheme to make money. Just about all training (LEO, etc.) is based on these programs, and this experience is why NRA is often cited as an approved source. As I mentioned earlier, I have never heard of your particular problem before now in WV or anywhere else, but I have not doubted your word. I am sure, however, that with a million or so licenses issued nationwide, if this was a scheme by NRA to make money we would have heard much screaming before now.
For TXR, many states have the same state certification requirement. What this normally means is that the state accepts your NRA credentials as proof of instructor training, but must also approve your course content so as to ensure the particular state laws are adequately covered.
And for Robert Hairless and SigLite, could we cut down on bashing each other so that we may get an answer to the original question.
