While we're always looking for a wide variety of great new plays and musicals for young actors and audiences, play publisher YouthPLAYS is particularly seeking awesome 30-35 minute one-acts for high school and middle school competition and festival use.

All roles don't have to be teen characters (though it's super cool if they are), but we do prefer that there be at least a number of substantial age-appropriate roles for teen actors. For submission guidelines, go here:
