You obviously don't understand the proposal
1) Under this scheme the schools will be removed from the control of those nasty, commie, LEAs, who top slice 99% of the education budget to spend on junkets and mayoral Jags.
2) The schools will have more control over teachers pay & conditions, reinforcing the ability of the better schools to siphon off the more capable staff - after all, those chavvy council estate scum don't want to learn, so why should good teachers have to waste their time trying
3) The schools can 'opt out' of the national curriculum, and can choose which qualifications are most appropriate for their pupils. Without any comparative measure to determine between schools, as each follows it's own ideas, we can then do away with league tables, as they will be even more meaningless than they are now
On a more sensible note : If the schools are out of LEA control, who deals with school admissions, and who mediates disputes and over-subscription ?
