As for Ofsted - that was set up under John Major, who, as I recall, was some kind of Conservative Prime Minister. Reorganised in 2005 to cut down the long advance warning of inspections, which was seen as screwing-up schools, by encouraging them to fiddle their timetables and so-forth to get a better inspection result.

It's still a pretty crappy way of running an inspection system. One thing unites all parties - they think they know something about teaching, and they don't.

Those who can't teach inspect. Those who can't inspect tell inspectors what to do.
