What does the actual PE course consist of?
If it is a traditional classroom course ask what material will be provided (manual, handouts, etc.) to each student and how will the course be taught (lecture, group discussion, etc.). Professional trainers generally utilize a blended approach (print, electronic, etc.) that includes professionally prepared PowerPoint overheads and handouts. If it is a distance learning self-study course ask what material is provided (manual, software, audio, online help, etc.). In either event, know what you are purchasing.
