Very true, adults cannot model the skills because they have no training or experience. And the powers that be think online learning is enough. Bill Hillcourt said it best " SCOUTING IS OUTING!"
But I am leery of outside certifications. I remember when LNT Trainer was a Scout POR that required LNT Trainer certification, but most places offering it wanted you to be 18+.
And to be honest even going through training is not enough. I went through Aquatics Supervision Paddle Sports training, and am certified to teach paddle board to Scouts. Just because I am certified, doesn't mean I have the knowledge or skills to do it. 2 to 3 hours on a paddle board was not enough time, especially with my balance to master those skills. Give me a canoes or kayak any day.
Once upon a time, national allowed a test out of IOLS. You had to demonstrate ALL of the skills, and if you missed one, you had to take the course. That lasted a year or two because some folks were just pencil whipping the training. Which considering the standard of one and done, pencil whipping is the norm from national.
Unfortunately pros are judged by the number of units they have, even if they are substandard. So there is a LOT of pressure on them. I tried to focus on quality, not quantity, and my boss gave me hell for it. And trust me pros cannot remove unit leaders. When I was a DE, we had a pack that had extremely poor leadership. I could recruit 30 Scouts for them, and 5 would remain. The #1 complaint was the CM, they needed to be removed. I had a chat with the COR/IH, who was an involved Scouter. But even he was unwilling to remove them because he had no idea who to replace them with.
As for unit visits, I can tell you I had one unit I started having a lot, and I mean a lot, of challenges. I was doing my best to help them out by basically serving as their commissioner as we did not have a commissioner corps ( that is another story). My boss chewed me a new one for helping the unit out. I got around that by visiting them as a member of their CO, the service organization that I belong to.
Until national wants quality over quantity, we will continue circling the drain.
