Hunter Safety Education has always been a very strong argument to people who think hunting and hunters is/are unsafe (it and they aren't by the way, -unsafe).
When my now 37 year old son was 10, I signed him up for Hunter Education in the state we lived in at the time. My age precluded me from having to take it. I was curious how much my son had learned from me, simply tagging along and from all the conversations he and I had about hunting and firearms safety. I was not a hunter education or bowhunter education instructor at the time. I was merely a dad eat up with hunting with a son who loved tagging along and talking about it with me. We remain very close today - he lives across the creek and woods from me that I'm looking at as I type this post.
As an experiment, I was able to give him the exam before he took the class. He scored a 96 (I was pleasantly surprised by the way).
When he took the class a few days later (me with him) he scored a 98 on the exam (missed one). I also scored a 98. We both missed the same question, how moving the REAR sight on a firearm affects point of impact. Archery (front sight vs. rear sight) was why I missed the question and I was, of course the reason my son missed it.
Obvious lesson is that quality time spent with our children is extremely effective. By the way, I've used this anecdote many times over a 30-year state wildlife biologist/director in policy discussions about Hunter Education.
My son and I both took the class again in Kansas just for fun. I included him in one of my Bowhunter Education classes when he was 32 years old.
There is no substitute for proper parental guidance. I will readily admit there are some parents who need a lot of guidance themselves. I fear a poacher begets a poacher? If the parent climbs a fence with a firearm or puts a loaded one in the truck, etc. So, in those cases maybe a quality HE instructor has a chance to break that chain?
Several years ago a survey was conducted to determine the recruitment or barrier impacts of Hunter Education. It was found that hunter education is a barrier that 2% of would be hunters aren't willing to surmount.
The one thing I wish could be removed from some hunter education classes is the bias of some instructors. Some instructors stray from the lesson plan and inject their own opinions. Some of those opinions are invaluable, some aren't. I'd gladly give up the valuable ones for the bad advice.
I'm a fan of on-line courses although I've never taken one. One of the reasons I like on-line (besides the convenience) is the standardization in represents ... only the facts please. Some may argue that hunting is important enough for a wannabe to undergo some inconvenience. I don't disagree. Imagine the liability agencies would incur if they dropped hunter education requirements completely and then the non-certified and non-mentored hunter is hurt or hurts someone?
I'm even a bigger fan of the new "Mentor" laws that allow a would be hunter to go with a hunter education certified person the first year. Then, if they want to continue hunting, they have to take a course. This let's hunting sell itself before asking your neighbor, son-in-law, etc. who might have only a mild interest in hunting to try it before spending 10 hours of precious time taking a course. Some who take HE courses never follow up hunting. These laws are so smart.
For years wildlife officials implored hunters to invite their neighbors, friends, and co-workers to keep hunter numbers strong. I've had such discussions with those non-hunters. You invite them to go and they agree, until they find out they have to spend 2-5 nights/week to take and pass a Hunter Education class. This kept my son-in-law out of hunting for nearly 8 years (he was overseas military most of that time). Now they can try hunting in more than half the states through these mentor laws ($5 permit plus proper licenses here in KY). The agency can then track whether or not that mentored hunter takes Hunter Education later.
