You can find auditions for child actors by using websites site such Backstage and Casting Call Hub. Each site posts recent announcements of roles that children and teens can audition for.
In the Kids and Teen Auditions section of CastingCallHub.com, the site displays recent casting calls, with the most recent appearing on top. The page displays the name of the production or a brief description of the role, and is then followed by a longer description. Those needing additional information for any entry can click on More Audition Info. This typically provides more information about the role as well as videos, production websites to visit and instructions for those preparing to audition.
The Backstage.com has a similar setup, with descriptive titles followed by very brief descriptions of the roles. Users may then click on the title to view a fuller description, which typically includes age range, expected pay and the date range. Users can also search auditions posted according to keywords or by age and ethnicity the company is seeking to cast.
While there is generally enough information in the descriptions to find the audition, Backstage encourages users to become monthly or annual members of the site; one of the benefits of membership is that you can then apply for the audition directly through the Backstage website.
