The judges at a dance competition are typically dance professionals. They usually sit among the audience while observing the dances. Each judge completes a scoresheet for each routine by awarding points for various categories such as; technique, facial expression, costume, choreography, and over all impression. They may also write comments on their scoresheets or, in some cases, record audio comments for the benefit of dancers and their choreographers. When audio comments are recorded, they are typically given to dancers on CD or DVD media to allow review of a performance while listening to real-time judge commentary.
