There are dozens of people in central administration in every school system that, when you see them at work, you scratch your head and say, "I wonder what that person does.". Then you find out their title. It doesn't tell you much (Associate Superintendent for Implementation and Compliance). So then you ask. Many times even they can't tell you what they do. Sometimes every time you go to the Central Office you'll see them carrying the same sheaf of papers you saw them carrying the last time you were there. Ask a teacher what he or she does and you'll hear it with details if you ask for them. Your eyes will glaze over with the stats and data everyone of them has to keep track of outside just the grades.
My favorite was the guy 12 or so years ago that went around to schools and showed Social Studies teachers how to use a VCR to show movies. He got $90K/year.
