Contests are important and having them judged correctly is very important. This link will start a PowerPoint presentation used by Sandy Kardis, Jason Finks, and Curtis Scroggins on a training session for judges. It is short and very informative. This should be required viewing for all Toastmaster judges.
Also listed is a "When You're the Judge" video training from TI.
