That is correct. And it is what most (if not all) NRA courses are built around. You have to take the things you've learned in class and go practice them.
People in Idaho can get a carry permit with a hunters safety course or any NRA handgun course from First Steps on up. Some of those are at the discretion of the Sheriff in terms of whether they satisfy the training requirement.
The new Idaho enhanced permit requires an upper-level NRA course or its equivalent. The law states that a sheriff must accept Personal Protection in the Home OR Personal Protection Outside the Home. Equivalent courses may be accepted at the sheriff's discretion.
Of late in my area there are NRA courses offered. There also is one outfit that is skirting the boundaries of ethics and doing an "enhanced" class that is just the Utah class plus magazine dumps. The courses are supposed to include all sorts of shooting exercises (with a minimum of 98 rounds) and draw exercises plus legal instruction. The local group I am mentioning is just doing magazine dumps to get the round count up.
Its legal, but not cool in my opinion. Even with the law specifying training minimums you still have people finding ways around the rules to make money off people who think they're getting training.
Personally, I prefer the NRA courses. Say what you will about the NRA, but their courses are tight if they are taught correctly.
