I know that tech remains a weak link for many middle and high school theatre educators (fewer and fewer, but still many many). And I know how overwhelming the job is, teaching multiple "preps" plus directing shows plus producing all of the tech aspects. There is no time for taking tech theatre classes at a local university; there's barely time to breathe. On the other hand, you know that building a strong program means including tech - and those kids who are hungrier to create backstage than risk being onstage - and that means teaching it.
