First you have to decide under which set of rules you are going to play.
Then get those rule books and give them to the officials to study, and take a test from.

if you were to go to the E-officials site you can download and print w/o cost the NCAA rule book, case book, and there are a fair amount of training videos and other information. If you pay the Fee there are even more areas available that could be helpful.

I would run a training class from that information and then test your people - those who pass can officiate and those who don't, well they just have to study harder - contact some local officals assoc. and see if you can get some help from them regarding training. depending on the security level of your facility someone may even be willing to run a sanctioned class for you for Federation - FIBA - or IABBO.

Someone may even be willing to floor train with some officials - that would be a different situation, but maybe possible.

There is a lot of inforamtion available, and probably people willing to help this would be just a first step and there are quite a few along the way.
