The government said last year that outstanding schools would no longer be routinely inspected. However, Wilshaw has told the BBC's Today programme that there will be inspections for schools judged 'outstanding' overall that do not meet this standard in teaching and learning. He explained: 'I don't see how you achieve "outstanding" status unless the quality of teaching is also outstanding. That is something we will need to review in the next weeks and months.' 

Wilshaw will deliver his first speech as Ofsted's chief inspector at a school in south London later today. He is expected to say that since outstanding schools have a duty to support underperforming schools, the teaching they offer needs to be of the highest quality.
