Auditions for each show are hosted up to a month before productions go into rehearsal. Generally auditions are done before the production crew, a mentor, and other members of the Society that the production crew has asked to help out join. Casting is determined via these auditions by the director and producers of the show.
Audition notices will specify what materials potential cast will need to prepare for an audition, if any. Auditions could include cold reads (no preparation required), prepared monologues, presentation of a song or vocal scales (particularly for the spring musical), and movement and choreography.
