Suspended exam chiefs are to be grilled by MPs over allegations they gave unfair advice to teachers on how to boost GCSE and A-level results and made exams easier to attract more business.
A House of Commons education committee will question three examiners after the Daily Telegraph claimed to expose a culture of corruption through their secret footage last week.
Steph Warren, head of Edexcel GCSE geography was caught boasting how "easy" her exams were for students. The Edexcel official , who is responsible for setting exams for tens of thousands of students, was captured on film saying: "There's so little content we don't know how we got it through."
The undercover investigation also revealed teachers paying up to £230 a day to attend seminars with chief examiners to receive "advice". Paul Evans, a chief examiner for WJEC GCSE history told his audience exam papers go "through a cycle".
Both Paul Evans and Steph Warren, as well as Paul Barnes, will face MPs on Thursday.
