I had a father/daughter approach me at a recent gun show about our classes. He wanted her to get her CHP permit.
He said that he had his but was not familar with the training requirements. He said that he never took any kind of class, firearms safety, hunter safety, military, nothing...
I asked him how he got his permit and he said that he just asked the Judge for it and the Judge gave it to him. When I said "do you know the Judge?", he said "oh yeah sure, we've been hunting together for 30 years".
In that case, the "court" knew that over a 30 year timeframe, he had handled his firearm safely during numerous hunting trips, therefore the court deemed his practical experience adequate.
Now, as an aside, I would suggest against you doing this kind of training unless you are prepared for the risk. Our company is licensed and insured against any firearms related training accidents. If someone were to have one, you could be open to a serious lawsuit. Also, I doubt that anyone would come to your class if you did not have some type of certification.
