When did we stop ‘tossing’ coins?

What kind of scientists do school inspectors not need to be? ‘Inspectors don’t need to be rocket scientists.’ For what must we make sure that the school inspection regime is fit? ‘We make sure that the school inspection regime is fit for purpose.’ In what manner do we need an independent schools regulator to inspect all schools? ‘We need an independent schools regulator that inspects all schools freely.’ Apart from freely, is there another manner in which we need an independent schools regulator to inspect all schools? ‘We need an independent schools regulator that inspects all schools freely and fairly.’ I don’t really mean to make fun of Jonathan Simons’s remarks on his excellent report (with Harriet Waldegrave) about Ofsted, for Policy Exchange. If rocket science, fit for purpose and free and fair are clichés, are not clichés the poetry of the people? I was surprised, though, by the wording in Mr Simons’s press release of its most memorable judgment: that ‘you would be better off flipping a coin’ than relying on an Ofsted inspection.Why
