Select the source of your play. You may ask students or local playwrights to submit new scripts to you, so that you can select a winner from their entries. You may prefer, however, to use a script that has been staged previously.
Check the technical capabilities of your theater. Some plays call for special equipment, and if you cannot provide it, avoid those scripts. Some plays also require a certain size stage for a performance.
Consider the age group of the students who will be performing the play before you select a script. In addition to making sure that the material is age-appropriate, ensure that the vocabulary and concepts are not too difficult for your actors to handle. Young actors typically do better with material that they understand.
Adapt a script to your needs, if necessary. For example, you may need to update the setting of a play in order to find costumes and props for your actors. Editing out parts that may be inappropriate for the age of your students may also be a possibility.
Get the script you select approved by school administrators. Although it may not be necessary to produce a play at your school, it can make the process easier if administrators agree with your choice.
