David Hoare has been announced as the new chairperson of school inspection body Ofsted.

Replacing Baroness Sally Morgan when she steps down in September, Mr Hoare will draw on extensive business experience at organisations such as Bain and Company, Virgin Express and the DX group, in his new role at the head of the inspection body. He is also chairman of the Teenage Cancer Trust.

Education secretary Nicky Morgan said she was “delighted” to appoint Mr Hoare, who was chosen on the grounds of his strong foundation in business that will enable him to lead Ofsted through a period of significant change.

However, he has also attracted scrutiny for his close relationship with the academies movement. Not only did he serve as an academies ambassador for the Department for Education, but he is currently a trustee of the Academies Enterprise Trust (AET), which is struggling with poor performance.

AET runs around 70 schools, but was prevented from expanding any further last year after concerns were raised about standards in some of its schools. Ofsted has criticised what it said were falling standards in some institutions, and is due to release a letter summarising the results of its latest round of inspections.

Mr Hoare was made a trustee in January as part of a move to improve standards, but will step down to take up his new post at Ofsted.

TES says that AET has responded to the draft version, but no final version has been approved so far. The publication of the letter will not be taking place this week as planned, TES reports, but this is not believed to be due to Mr Hoare’s appointment.

Kevin Courtney, deputy general secretary of the National Union of Teachers, said that the move could be seen as the government’s next move in the “politicisation” of the inspectorate.

“This could further widen the credibility gap between Ofsted and schools, and the new chair will need to demonstrate his competence to chair the school inspectorate in an impartial manner with regard to all academy and community schools,” he added.
