Can An Unregistered Official Officiate MHSAA Volleyball Contests?

It IS permissible to play a match with only a single official assigned, but it is never permissible for an unregistered official to officiate an MHSAA VB contest as either the R1 or  R2. A coach may not serve as an R2 unless he/she is registered.

Disclaimer: You MUST still register with the MHSAA in addition to a registered association in order to officiate volleyball. Note that registering with the MHSAA is usually not available until about June 1 of each year. Please check back to register with MHSAA, or don't forget. Just be sure you ultimately register for both. Note: If you are a new official with the MHSAA, you can request a voucher for your first years' registration fee with them, but you MUST request the voucher prior to your registration. It will be void if you register first.
