I am not sure if anyone is properly educated. Most of it comes through peer education. I hate to admit it, but I learned my skills through trial and error (i.e. dead fish) and the appropriate razzing from fellow anglers.
The other issue is the rules are not consistent between species. It is totally OK to handle a pike by the gill covers. Actually, it is the best way to get control of the fish and avoid the use of jaw spreaders. Again, it is totally OK to handle a bass by the lip, but a faux-pas for almost every other species.
I also believe there is no excuse for poor handling skills, but unless we can provide educational materials to anglers at the time when people get licences, we will continue to have armies of dingus khans.
