Adjudication categories vary at different competitions, but commonly judged categories cover aspects such as showmanship, technique (i.e., proper form, execution of movements, transitions), difficulty of the routine, costume, choreography, and musicality. At some competitions, points may be deducted if the costume or music is deemed inappropriate for the age of the dancers. Also, judges may disqualify a routine if it violates any rules of the competition.
The points issued by each judge are totaled to compute the judge’s score. Typically, a maximum of 100 points can be awarded by an individual judge (i.e., a perfect score). All of the judges’ scores are then added together to produce a final score. At some competitions the lowest and highest judges’ scores are discarded before computing the final score. For example, a competition might employ five judges, each of whom may award up to 100 points; when the low and high scores have been discarded, the resulting final score will have a maximum possible value of 300 points.
