Mask Requirements for MHSAA Officials (1/6/21)

From Brent Rice
Assistant Director, MHSAA

MHSAA Officials,

As we approach the resumption of fall tournaments and the beginning of winter sports seasons, it is important that you are reminded of the expectations for MHSAA officials regarding masks. Please use the link below to review the most up-to-date information regarding the use of masks by contest officials.

Please know that the MHSAA and its member schools are obligated to uphold these requirements as the organizers of sports. Officials must comply with the minimum standards included in this updated document to ensure that our student athletes can continue with their seasons. Thank you for your understanding and cooperation.

Useful Officiating Resources

Many officials are utilizing electronic whistles this season. Below is a link to a short video providing some useful tips and good examples of electronic whistle usage. While primarily developed for volleyball officials, many of the tips and mechanics can provide guidance to all sports officials.

Don't Forget to Pay for Your 2020 Membership!

Membership dues are still being accepted for the 2020 season. Remember that this membership is good through June of 2021. Your 2020 dues must be payed by January 31 and prior to your dues for 2021. If you have questions, please let us know.

The best and preferred way for us to process your dues is via this website, where you can click the 2020 Membership "registration" link on the right, and follow the prompts. You can also simply send us a check. That option will be available through this same registration link.

If you will no longer be officiating for the upcoming year, or moving out of our assigning area, please drop us a message.   

Keeping Your Calendar and Preferences in Arbiter Updated

Remember to put blocks on your calendar for dates that you cannot work.

We need for you to keep your calendar up to date every day of the week. Please do this in order to alleviate the need for turnbacks. Nobody knows your calendar as well as you. Be considerate to our assigner, use the block feature whenever you know your dates are changing.

If you have ANY questions regarding the use of ArbiterSports, please contact any CAAVO board member.

For those of you that entered the gyms this year, sometimes officiating extra matches and weekends; knowing that you were putting your health in jeopardy. We can't thank you enough for going above and beyond this year. Your selfishness has not gone unnoticed. Thank You!
