Primary school pupils in England could be ranked directly against their peers across the country, under government plans to change performance measures.
Pupils aged 11 would be ranked in 10% ability bands and parents told where their children are placed.
Deputy Prime Minister Nick Clegg said: "For children to achieve their potential, we need to raise the bar."
But head teachers' leaders described the plans, which could come in 2016, as "disappointing and destructive".
