Well...within reason it means that almost anybody can get certified as an NRA instructor. That is why more people are certified through the NRA.
This is not the case for those who are certified through the law enforcement profession. An individual who wishes to be so certified must first be a commissioned law enforcement officer, and usually the requirement is that they must have an ample supply of street experience first.
Most law enforcement firearms instructors are also certified to instruct in other areas such as, defensive tactics, verbal judo, defensive communication skills, Taser, Legal updates, and many, many other areas. The combination of all of this training creates an instructor who is well versed in many aspects of day to day defensive living. They can bring more to the table than someone who has acquired some basic knowledge and several skills through a basic NRA instructors course.
So you see by virtue of the fact that most CCW instructors are NRA certified this puts them in the classification of the "average" ccw instructor.
And by virtue of the fact that only a few people with law enforcement commissions, experience, and backgrounds can even take a law enforcement certified firearms course, this would put them in the classification of the "elite" The elite are usually better trained with more experience in many aspects that carry over and apply to the practice and mastery of concealed carry.
Even the instructors who are both NRA and LE certified agree.
