I'm not sure 'Mandatory Training' is the answer. Well, I think some is needed, but some of the suggestions made really make me think that the program would lose too many good leaders.
I'm going into a career where to be employed, I will have to be certified (psycho

) and in order to remain certified I will have to be continually learning.
I don't think it should be something like that to be a VOLUNTEER. I believe some basic training (YPT, Scout basics) is needed, but requiring Water this, Water that, Climbing, WoodBadge, etc? Sure there'll be good "trained" leaders, but those leaders better have a lot of free time because they'll be busy if a unit is going to have an active program. There won't be many who actually complete the training.
