The Economist:

IS YOUR son an accomplished violinist? Buy a house near one of the many state-funded schools that can now prefer pupils with musical talents, and he will sail to the front of the queue for a place. Is little Johnny a whizz at maths? Alas, only a few scattered patches of England now have academically selective “grammar” schools that can legally admit him ahead of his innumerate friends. Piety might help: have him baptised and attend services regularly and he could win a place at one of the many high-performing church schools.
England’s state schools have an absurdly complex rule book for how they may and may not choose their pupils. (The rest of Britain goes its own way in education policy.) This infuriates conscientious parents and forces them to resort to all sorts of tricks to get their offspring a decent, publicly-funded education. Michael Gove, the education secretary, is bent on overhauling the rules. But it will not be easy.
