Staff wide trainings are a completely different beast. You have a group of people with varying levels of expertise, exposure, and (frankly) interest. How do you create a training program that is comprehensive enough to give good, uneful information yet broad enough to be applicable to all the students on your caseload. Some teacher/aids need to learn how to turn the device on/off & be sure it is charged while others want to know how to program and create user areas.
I have a few trainings that I run pretty consistently (1-2 times per year) as we are always getting new staff members and our staff are changing programs. The first training focuses on communication partners recognizing and responding to all communication attempts. I cover the basics of behavior as communication and shaping these communication attempts.
