Bit of sweeping statement about the whole profession, Villain. Are you basing your opinion on an in-depth knowledge of the teaching profession or just an in-built prejudice? My wife's an eductaion lecturer with an MEd and spends all he working life in schools, largely in deprived areas. She will confirm that the standard of teaching is, largely, excellent and, where deficient, is almost always picked up by OFSTED inspectors and remedial action taken.

But, hey, don't let anything as boring as the facts get in the way of your argument!
