In my limited experience, theatres connected to state-run schools come up with amazing hoops to jump through in their hiring process. Most of it is behind the scenes for the applicant, and just a bunch of paperwork that the person doing the hiring makes their assistant do. It's because the people responsible for making sure theatre hires are quality, don't have any notion of what we do. If you know your job, any written test they give you ought to be a piece of cake no matter what format it's in, because the people writing the test don't have the skill set to do our jobs.
Don't sweat the test too much; it won't be an SAT. It probably won't be incredibly detailed. I agree with smalltimeSM, check their inventory of equipment beforehand and brush up on any pieces that are unfamiliar to you (short of reading the owner's manual from front to back cover - just know what the capabilities of the boards are, etc.).
I would suggest (because of the state-run school aspect) that you concentrate your preparation on SAFETY. Review what you know of fire exits, earthquake procedures, OSHA rules, etc.
Good luck!
