Occasionally a referee will enroll in a training clinic and need to switch to another. This can be accomplished in the GameOfficials registration system.
First, log in to the registration system, navigate to the clinic the referee originally registered in under “Confirmed Registrations." Click on the course number to open up the class then choose “Cancel Registration." This frees up the payment to be applied to another course. Then enroll in the new course. You must cancel first for this to work correctly.
