Audition Etiquette

Research the Show/Role: Before even setting foot in the audition room, take the time to understand the play and the character for which you want to audition. Each show page will likely include a synopsis and character breakdown to help you in this task.
Prepare an Audition Piece: Choose and prepare your audition piece well in advance. Be it a monologue, scene or song, ensure that you are not only comfortable with the material but have also practiced it thoroughly. Again, each show page may include details such as "prepare a short monologue" or "prepare a song in the style of the show."

Presentation and Body Language: Your first impression begins the moment you walk through the door. Dress appropriately including close toed shoes and clothes that allow for movement (especially if auditioning for a musical). Be courteous and friendly as you follow instructions for signing in, turning in paperwork, etc. Maintain positive body language—stand tall, make eye contact and greet the casting panel with a warm smile. These non-verbal cues convey your confidence and eagerness to engage.
Demonstrate Personality: Whether performing a monologue, reading a scene, singing, or dancing remember to let the audition panel see your enthusiasm and personalty. Be engaging and attentive to instructions and feedback; if adjustments are suggested, take them in stride and show your adaptability. Remember, the panel is not just evaluating your acting skills, but also assessing your demeanor and how well you might fit into the project’s dynamic.

Be Ready for Callbacks: Not every audition requires callbacks, but you should be available in case they are used. Also remember, that a callback does not guarantee a role in the show. Treat callbacks like a new audition with the same attentiveness in your dress, personality, and enthusiasm, and don't forget to apply any suggestions the audition panel gave you before.
Refresh, refresh, refresh: Sometimes the hardest part of auditioning is awaiting the posting of the cast list. Casting can take hours to iron out, especially with a large show or musical, so now you have to practice being patient. Oftentimes, the cast list is simply posted to the show page when available; however, sometimes actors are contacted directly by phone or email to confirm/accept their role prior to publication.

What happens next?

If you were cast: Email the stage manager to accept your role, then attend the company meeting (date/time/place on the audition form). There you will learn about schedules, communication streams, etc.
If you were cast in a different role: Not every actor can be the main character in the story, but every character is important to the story. There are no bad roles from title character to ensemble, so please accept the offered role and embrace the overall experience.
If you were not cast: Do not be discouraged! Every audition is a valuable learning experience. Feel free to reach out to the stage manager and ask for feedback to help you improve for future auditions; they can also tell you if there are other ways to be involved in the production like working backstage.
