Becoming an MHSAA Registered Official is easy: 

The first step is to register in your chosen sports with the MHSAA at www.mhsaa.com or click here.  You are registering with the MHSAA as an independent contractor and not an employee.  You will be given detailed registration instructions and can complete your registration in a matter of minutes.

Once registered, you will receive an Officials ID Number, Login information, and Sports Rules Books from the MHSAA. New Officials must take an MHSAA Officials Guidebook Exam and complete a Mechanics Exam if registering for football and/or basketball.  The Exams are open-book, and may be taken online. 

The next step is to notify and join a local association such as the Kalamazoo Officials Association. The Kalamazoo Officials Association (KOA) is a basketball, football, baseball, and volleyball association.   If you are interested in other sports, the MHSAA maintains a list of approved associations for other sports that may interest you.

 The KOA provides rules meetings, clinics and other learning opportunities for rookies and veterans alike.

After registering, the final step is to contact the Assignors in the area. They will email you an invitation to register on ArbiterSports.  You will need to update your availability on ArbiterSports. This will allow the Assignors to assign you any available games.  It also helps to network with other officials and with athletic directors at schools. Start with a level you are comfortable with (usually middle school), and remember there is no substitute for knowing the rules.
