Ofqual will be questioned by the Commons Education Select Committee next Wednesday, it has been announced.

Sally Collier and Roger Taylor, the exam regulator’s chief regulator and chair, will be called in to respond to questions about “errors made in the process of awarding this summer’s exam grades”.

The committee will also ask how schools and students affected by the downgrading of results  - and the following U-turn - will be supported, and what lessons have been learned to ensure that a fair system will be in place if exams are cancelled again in the future.

Education secretary Gavin Williamson is also likely to face questions about the grading crisis when he appears before the committee for a regular accountability session on 16 September, the committee said.

Committee chairman Robert Halfon criticised Ofqual today during an online interview run by the Campaign for Common Sense - a group set up by former Bedford Free School founder Mark Lehain.

Asked by Tes what the committee’s plans to address the grading fiasco were, Mr Halfon said: “I want to find out what on earth went on, why Ofqual wouldn’t publish the [grading] algorithm, what questions were asked by ministers, what questions were asked by Ofqual, did Ofqual reassure the ministers that the system would be fair, how much does it all cost?”

He also said the regulator should be more transparent.

Mr Halfon added: “It would be good if Ofqual were much more transparent…they should deal with the press much more than they have done, and they should be communicating with schools much more than they have done.”

However, he said that he is not going to call for resignations.

“It’s not my job - it’s not my kind of politics either,” he said.
