Performing Shakespeare with others is life-transforming. There's actually science about that. But never mind the clinical studies, check out what some Santa Fe youth have to say (click "About"). Participating in a school team provides community and opportunities for growth. Ask your English teacher or drama coach about taking part.
If you are a home-school student or would like to participate as an individual, you can apply to be part of a classical monologue project in which you will prepare an audition-style speech from a Shakespeare play and present it at the festival. Rehearsal times will be worked out on a case by case basis.
