Determine the resources available to your production. You may need to check with school administrators regarding budget, equipment and the use of school facilities. You may also want to check with the school's theater department, which at some schools is a part of the English department.
Select a play to put on. You may need to have your choice approved by school administrators, and you will need to make sure that your stage has the necessary technical capabilities. The material in the play should be age appropriate for high school students.
Audition students for the various roles. Many schools encourage directors to assign leading roles to seniors or upperclassmen, though you will need to make sure that they are capable of handling the parts.
Organize a stage crew. You will need crew members capable of handling sound, lighting, props, costumes and other technical details. High school students are typically responsible enough to handle lead stage crew positions.
Prepare your production. Organize rehearsals with your actors, and arrange for stage crew members to practice their duties. You should also oversee the stage crew members that are responsible for acquiring props, building sets and creating costumes.
