Dance competitions specify which forms are to be judged, and are generally available in three different formats: strictly is where one couple competing together in various heats, to randomly selected music, where no pre-choreographed steps are allowed. Showcase is where one couple competing together for a single song which has been previously choreographed. Jack and Jill is where leads and follows compete individually in various heats, where their partner is randomly selected. Judging for competition is based on the three "T's" as well as showmanship (unless the contest in question designates the audience as the deciding factor). The three "T's" consist of: timing related to tempo & rhythm of the music; teamwork, how well a lead and follow dance together and lead/follow dance variations; technique, how clean and precise the cooperative dancing is executed. Showmanship consists of presentation, creativity, costumes, and difficulty.
