It s more important for the students and you to have a good experience than it is to do a technical masterpiece. No matter how simple the show is, there are going to be important technical aspects to consider. Seek out help in departments on your campus that have expertise. For example, if there is a sewing class, the teacher may be happy to have some unusual projects for the sewing students, such as making costumes. Call the woodshop teacher for help in getting wood cut or building needed items, such as platforms.
Parents are also a good source of help on technical work.
Ask in rehearsal if there are parents who can sew, build, or bring props. Certainly having parents involved enhances and builds a sense of community around your program. Rehearsals Start and end rehearsal on time as much as possible. As with so many other aspects of high school teaching, students will respond to your expectations. If you start rehearsal late, they ll arrive late.
