Pathetic says Chris Dillow of the £430 pupil premium suggesting the correlation between school spending and attainment is weak (pdf), and from that he extrapolates that around £100,000 per poorer pupil would need to be spent to equalise opportunities to the levels achieved by Nick Clegg and his privately educated Coalition partners: remember that public schoolboys have the advantages of high expectations, social contacts and good role models, whilst many of the poor have family circumstances not conducive to learning.
Perhaps that pupil premium could be used to further that all-important environment through homework clubs, personal tutors or 1-2-1 tuition? Now that's what I call a premium education on the level of Westminster School. It is also all about teachers, not buildings and expensive resources, where Labour spent our money. And it certainly wouldn't cost £100,000 per pupil per year.
