In many states, the first step to getting a CCW permit is to take some kind of "gun safety" course. This course is mandated by state law and the state usually provides a list of approved course instructors.
In many cases, all it takes to become a state-approved gun safety course provider is to be an NRA certified instructor. As I've sagely noted before, becoming an NRA certified anything is a function of paying the fee and a few hours of your time.
Nobody fails any NRA training.
As the Washington Post's Courtland Milloy discovered, many of these gun safety courses are taught by blowhards who more interested in signing you up for the NRA and bloviating about evil liberals than teaching anything about gun safety. In fact, Milloy's instructor, Jim Reynolds, seems to have difficulty accepting a black man as President.
That aside, there exist no standards as to the conduct of these trainers.
