Ofsted have warned that many of England's most able pupils are being failed by a culture of low expectations.
The report found that in non-selective schools, 65 per cent of pupils who achieved top levels in English and Maths in primary school did not gain an A or A* at GCSE.
The education watchdog called on schools to do more to challenge the minds of the brightest pupils and to consider streaming pupils when they first start secondary school.
