How do you become a ref in Michigan?

[CJRef]

My apologies for the generalization. Per the MHSAA Officials Guidebook....

Basketball (Boys and Girls) - Officials for all tournament contests are selected from a list of officials who have an "Approved" rating classification, attended a current years rules meeting, be a member in good standing of an Approved Association and submitted a current officiating schedule.

New this year due to the season change...if working boys and girls games, an official must work six games of each gender to qualify for the MHSAA tournament in both sports.
