Ofsted criticises levels of disruptive behaviour in class

Education watchdog Ofsted says low-level, persistent disruptive behaviour in England's schools is affecting pupils' learning and damaging their life chances.

A report says some pupils could be losing up to an hour of learning each day - or 38 days a year.

Ofsted chief Sir Michael Wilshaw told BBC Breakfast the situation was "quite frankly unacceptable".

Some head teachers have criticised the report saying the claims are not backed up by the evidence of inspections.
