You only need to attend one audition session, unless you are also invited to a Call Back for more intense work with the director
Bring a headshot if you have one - you will not have your photo returned to you
Bring an acting resume if you have one; this is not required, but it will save you paperwork time
Be prepared to notate ALL of your calendar conflicts for the entire rehearsal/performance schedule, including specific dates and times
Be prepared to do a read from the script; the script will be provided for you
For musicals, be prepared to sing a cut of a memorized song (Check the audition information for specific requirements as they are different for each production)
For musicals, dress in appropriate clothing and be prepared to learn a short dance routine (no flip-flops!)
Auditions may take a few minutes or a few hours; be prepared to stay the entire time, you will be notified when it is okay to leave.
