video tutorial.


Question: How often do I need to update my availability?

Every time it changes! Please remember to update your availability when you become unavailable at any given time.


Question: How do I decline a game I have already accepted?

By accepting an assignment, you are expected to honor it. While emergencies do arise, frequent declining of assignments after previous acceptance will result in the referee not being selected for future assignments.

If an emergency does arise, you must email the referee assignor AND you must call the referee assignor at (612) 466-0929.  If less than 24 hours before the accepted game, begin with the phone call.



Question: Where can I print off my schedule?

You can print off your assigned games, as well as other reports in the Reports section of GameOfficials, accessed via the left-hand navigation of the site. Make sure you read through the settings in order to print in the correct format.


Question: Can I self assign myself to open games?

If games remain open after hand assigning within a week or so before the game, they will go on self-assign.  You can view these open games in the Open Games section (accessed via the left-hand navigation).  If you wish to be considered for these assignments, email the assignor.
