I used to hunt on one of the military installations around here. In order to hunt there, you had to pass a proficiency test (among other things). It can be a bit nerve wracking when there's 50 or so people standing there watching you shoot before they get their chance. I think it's a good idea to help weed out those who don't practice and just grab a bow and go hunting (believe me, I've met some). On the other hand, the mobs that would line up there would be a big obstacle to this. I see it from both sides, but I'd favor making the test a part of getting a license.
