I agree with mick - don't keep too simple. You may not need to get too far into minutiae, but you do want give them as much information as possible.

My concern with newer officials (and some veterans, for that matter) has been their "communication" skills. That includes everything from the volume of their whistle, to the use of the proper signals, to verbalizing when needed, and communicating with their partner(s). I've seen so many new officials that may blow the whistle, and then go on with what they were doing because they knew what they called, but forgot to communicate with everyone else what they called. Or, they come running in because they saw something, but forget to blow the whistle and everyone keeps on playing. Communicating so everyone knows what's going on is very important.
