Look at the dance company's website to see what paperwork you need to fill out. There might be an application to fill out ahead of time.
Print out a few copies of your resume and head shot, and bring it with you to the audition. Bring a photo ID as well.
Check your audition information to see if you need to prepare an audition piece. Some auditions will ask the dancers to participate in a group dance class to form their decision. Some auditions also require a solo dance piece. These solos should be one to two minutes long.
Bring a CD with your music on it for your solo audition.
Follow any dress requirements the dance company might have. If there aren't any requirements listed, women should wear a leotard and tights, and men should wear fitted shorts and a T-shirt. Pull your hair back off of your face, and do not wear jewelry or baggy clothes. Be sure to bring dance shoes with you. If you own more than one type of dance shoe, then bring them all in a gym bag.
