What is an Instructor Course and why is there an additional fee?

Each EXPO may offer Instructor Courses as a part of the weekend event.  Instructor courses prepare and train volunteers to become instructors in their specific discipline.  There is an additional fee to register for the course(s) because it typically includes expanded learning materials such as manuals and handouts as well as lunch.  This additional fee typically covers these expenses. Pricing, course offerings, and what the fee covers may vary by EXPO location.
