A Norfolk high school was visited by Ofsted twice in two months after its headteacher deemed the inspection 'incomplete'.

Sprowston High School has made no overall change since it was rated 'requires improvement' by the watchdog – the grade above inadequate – in July 2014.

In the report published today, the Cannerby Lane school has been told it needs to better the quality of teaching and overall achievement.

Inspectors visited in March, but later returned in April. It is not clear what rating Ofsted gave the school after its first visit, but headteacher Andrew John said he believed there was more for inspectors to see.

He added: 'My opinion was that the evidence base from the first Ofsted inspection on March 10 and 11 was incomplete, and so I made it our business to do all we possibly could to help Ofsted understand our school.

'The report shows we are in a prime position and are well on our journey to being a solidly good school.'

The report says leadership and management, behaviour and safety of pupils, quality of teaching, achievement of pupils and sixth-form provision all need improvement.

Inspectors praised senior leaders and governors' success in some improvements to teaching and said provisions were made for spiritual, moral, social and cultural developments of students.

But they found standards had not risen quickly enough since the last inspection, the quality of teaching is too variable, the progress of disadvantaged pupils has not been rapid enough and work to tackle under achievement in the sixth form has not lead to enough change in A-level results.
