Does anybody have any hints or pointers for training new officials?

I'm the Training Officer for our board next season (www.kwboa.ca) and was wondering if anybody had any pointers of what to cover in our meetings. I have lesson plans from previous years but was wondering if anybody else had other ideas of what to do.

I will be working with the first and second year officials, we meet every second week. We have a classroom and no gym to work in (so it will all be board work, discussions and small simulations). We do have a training/evaluation tournament early in the season to get them some floor work.

Has anybody had success or failure with a mentoring program for Junior (1st and 2nd year) Officials? What has worked what hasn't?

Thanks,
Christina
