Primary pupils in England could be ranked nationally at 11

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".
