The Official View: The Crossroad We Face (

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.

Again, it is with great sadness...

we mourn the loss of yet another friend and colleague in the world of volleyball. Cheri Dobschensky lost her battle with Cancer on July 24, 2022. Cheri, we were blessed to know you. Rest peacefully.

Disclaimer: You MUST still register with the MHSAA in addition to a registered association in order to officiate volleyball.

Just be sure you ultimately register for both.
