If we're going to take this to the logical conclusion OFSTED inspectors belong at the bottom, the pile of educational traffic wardens.... if we want to play that game, you might as well complete the series:
Those who can, do.
Those who can't, teach.
Those who can't teach, teach teachers.
Those who can't teach teachers, do educational research.
Those who can't do educational research, become government education consultants.
