I'll be helping my church train a group of referees for the upcoming season. Most of these volunteers have had some experience, but probably are not particularly well versed on the rules and modern mechanics. The level of ball is not very good, but it's an important and popular youth program for us. So we do what we can.
As a bonus, we'll be training scorekeepers and timers as well.
Any suggestions on turning such a group into a well trained crew?
