 At most international events and other large National Championships (such as the U.S. Championships) there are nine judges, but at smaller competitions the panel might consist of between four and seven judges.An odd number of judges was needed to break ties in the old 6.0 system, but this is no longer necessary with averaging marks in the ISU Judging System.The evaluation of the Grade of Execution (GOE) for each technical element has clear guidelines from the ISU; it ranges from a "base value" of 0, to as high as +5 and as low as –5.
