A show in the franchise is typically composed of three phases of competition: initial open auditions, callbacks/finalist selection, and finals/live performance shows. A given series or season may air only one show per week or two, but rarely more. The initial open auditions are typically held at various locations throughout the relevant country and are open to dancers of varied backgrounds and experience levels, though generally there is an age cap (with the age limits being non-consistent between entries in the franchise). Although usually unseen in the final aired edit of the show, some productions may also hold producer auditions, in which the initial talent pool is screened, before the televised auditions. The open auditions are overseen by a panel of judges, typically experts in dance or the entertainment field, who will select a portion of auditioning dancers to advance in the competition. The following stage, sometimes called the "callbacks", "boot camp", or "academy" will further reduce this remaining pool of dancers down to the season's "finalists", usually by putting the dancers through a series of short dance workshops and routines while the judges evaluate their capabilities, adaptability, and over-all potential for the competition. The callback phase ends when the judge's panel selects a number of season finalists (typically between ten and twenty total dancers, half women and half men).
