Rookie/Mentor Programs

[paxsonref]

Curious for those of you in an association what types of rookie or mentor/mentee programs that you have to help new and inexperienced officials improve and advance, including topics such as training, observation, requirements (number or level of games), etc...

Our association has a rookie program, but I am always looking for other ideas or options as how to improve the way to bring the younger officals along to the point where they need to be.

Any ideas/feedback would be appreciated.
