Ofsted inspectors will return to Norfolk County Council next week, one year after a damning report which branded its support for school improvement as 'ineffective'.

That report, published in July 2013, was one of a series which plunged the council into a crisis over the performance of its children's services department, helping prompt the early departure of its director Lisa Christensen.

Last year's inspection was the first of its kind in the country, and Ofsted said it targeted the county 'because the outcomes for young people in Norfolk have been too low for a number of years'.

The subsequent letter to Ms Christensen said that the council had been 'too slow to challenge some weaker schools'.

Next week's inspection will be a key test of whether the council's much-heralded attempts to help schools improve are effective.

A spokesman for Norfolk County Council said: 'We knew that they would be returning a year after the previous inspection and welcome the opportunity to show Ofsted the progress that we have made and the improvements that have taken place across the county.'
