It is a fact, Oxbridge are given quotas they must fulfil in order to get their funding. The guidelines are ?70% (could someone correct the actual figure) state to private school. This goes against the actual attainment results percentage where privately educated children although 7% of the school population achieve a disproportionate number of high results. Why? Not because they are superior, but because they have been rigorously and thoroughly educated. The only sector that the private schools dominate is in the sciences (physics etc) where the gap can't be hidden.
This makes interesting the bitching from Oxford Dons in the Telegraph today: well, folks, you can't have it both ways. You can Change the World, or you can select to high standards.
But they can't, because of their quota and because they are already perceived to be 'elitist' and the class warriors who blight state education, simply do not support their bright students in the way that they should.
Compare this to Exeter university, which appears to have a policy of snapping up the private school Oxbridge rejects (hotly denied I am sure). Tiny little Exeter is now 13th in the university listings and climbing.
So I stand by my contention that, comparative to their actual attainment, privately educated children are discriminated against.
(Of course, the true solution would be for the comprehensive system to be dismantled, and implementing the European 3 tier streaming, and rigorous education demanding discipline and achieving attainment potential, as is currently demanded in the private sector. [You have been assessed as bright? By God, you WILL deliver A*! Private school kids are worked like dogs. The bad grammar and sloppy thinking that the Dons complain about is not tolerated]. But that would mean taking on the left wing ideologues who dominate the the teacher training colleges the LEAS and the Unions. It is desperately sad that BOTH governments have to go via the Free Schools and Academies route in order to bypass the Unions and the LEA. Free Schools and academies are INDEPENDENT of the LEA. Geddit? Which is why, of course, they are screaming like stuck pigs about it. More power to Michael Gove, and huge thanks to Andrew Adonis.)
Listen: you can get angry about this and you can accuse privilege etc etc. But the unchanging benchmark is the international league tables of education. Which the UK slips down year upon year. Estonians now outperform our kids! Instead of hating the private schools, get angry at the real problem: the structure of the state schools, and the prevailing worldview of the teachers, which a little bit of real-life competition would swiftly cure.
