Well, some things, like the shooting qualification details aren’t published. My guess is that’s because they want to evaluate your actual skills, rather than have you train to pass a test. And they do evaluate your actual skills.
A bit of background… Unlike some other subjects, firearms instructor programs don’t primarily teach you to use firearms, they teach you how to teach people to use firearms. They will certainly teach you firearms things you didn’t know, improve your information and improve your technique, but that builds on your already sound skillset.
Instructor certification courses focus on updating to current information and techniques, safe and effective teaching, ability to present, coach and interact with students, legal knowledge, and other teacher skills.
You’ll be a better shooter after the course but more importantly you’ll be a better teacher.
Ok, that said, I’ve never asked about what is pre-published and what isn’t (like the exact qual), and since this is a question that comes up from time to time, I’ll find out!
In the meantime a call to the training group at USCCA will get your questions answered.
As to maintaining certification once you have it, you are expected to be actively teaching. BTW, the NRA has the same basic requirements for certification and maintaining your certification. I’m certified through both and I like both, and I spend my time here on the USCCA site, so I’ll let you draw your own conclusions.
