BSA has evaluations. https://filestore.scouting.org/filestore/Outdoor Program/Shooting Sports/430-065_WB.pdf

I haven't looked at the SSM in awhile, but I know as of last year, you don't even need an RSO to run a range during summer camps. Outside summer camps, yes. During...no. Hmm.

But after 13 years of pushing this the membership numbers are still going down. What bad assumptions are they making? Maybe it's a bad assumption that just having scads of documents around will make it easy for parents to pick this up and do well. Have you ever wondered why so few parents are willing to volunteer for scouts? Is it really all their fault because they're lazy or is it too complicated on top of the fact that their work life is already insane. If summer camps can't get parents to show up unless they have wifi for checking into work then that's a hint there's a problem. I coached my daughter's 6 year old soccer team. It was pretty obvious what to do. Tell everyone to bring a ball. Get some cones. Make up some games. They learned the rules, they ran around and kicked the ball a bunch and they had fun. No literature needed. No databases or patches or SM conferences. I know the guy that taught the U18 team that almost won nationals. This guy was incredible working with the youth. His approach for these older kids was pretty much the same as mine except he understood soccer a lot better than me. Maybe kids like these types of competitive activities because the rules are simple and the challenges are both easy to understand and difficult to master. Instead, we have to argue about whether a scout needs to actually start a fire to pass the fire building requirement. And then we argue about one and done and retesting at SM conferences. And the scout still can't start a fire because the PLC decided that they didn't want to do skills competitions. Just a hint, but this is one reason why some parents don't want to volunteer. I'm not claiming I have the answer or that I even know what the problem is, but there is a problem. Scouting can be a good program. I've seen some amazing things. I see them much less now and it's a shame. My granddaughter is 16 months old and my grandson is 10 weeks old. I hope they have a scout program worth joining when they're 11 years old.

We do (about) three meetings per month, with a short PLC after each.  These build up to the outing.  Then, the outing... The regular meeting night after an outing is a full PLC (so one per month), where they go over all stuff necessary.  The other Scouts/parents get that night off to further recuperate from the outing. We have one day trip/service project per month... mostly an outdoor activity. So 4 meetings and two outings per month... 1/3 of our activities are aimed primarily at outdoors. We have the most successful Troop in the council. Most meetings (mid-spring through middle of fall) are outdoors with a game or activity (pioneering/fire building/nature walk, etc)  In summer, we throw a lot of impromptu stuff in as well... swim parties, bike rides, orienteering, fishing, hikes, boating, the odd service project, etc.   Seven or eight Scouts show up and we go have fun.  Never the same group twice.  (Ice cream is mandatory ;P)
