HI there!
 
I am a certified firearms instructor and the certified instructors are
"encouraged" to wear the official id shirt that identifies us as
instructors.  Perhaps the judges could also wear a polo shirt that
identifies them as a certified judge.
 
It helps if the show personnel also wear id shirts.  This works great for
horse shows and seminars!
