Two more schools have been dragged into a cheating scandal amid allegations that students were leaked information about exam questions.
Winchester College suspended head of art history Laurence Wolff after it was alleged that he gave students tips on what would feature in two exam papers.
The school confirmed results from the exams sat by 13 students had since been nullified and based on coursework and previous grades, according to the Daily Telegraph.
Charterhouse School in Surrey has also been investigated by the exam board after it reported concerns that students were given advance warning about questions on the papers.
But exam board Cambridge International Examinations (CIE) said that there was no evidence of wrongdoing by Charterhouse or its students.
Tim Hands, headmaster at £30,000-a-year Winchester College, said the school had treated the matter ‘very seriously’.
‘No boy was to blame for the exam irregularity, and the Board used standard procedures to award final grades,’ he said.
‘One teacher was suspended and has now retired from the school, and all those boys holding university offers dependent on a grade in Art History have now had those offers confirmed by their first or second choice university.’
A letter has been circulated to parents to inform them of the investigation and its findings.
The latest scandal comes just days after Eton College dismissed deputy head, Mo Tanweer, following allegations that he had shared confidential information about an upcoming economics paper.
Both Wolff, who is the son of scientist Professor Heinz Wolff, and Mr Tanweer were also working as examiners at the exam board.
There were calls for ministers to prevent the dual role with concerns it presented a clear conflict of interest.
The Department for Education said that the exam regulator Ofqual, was now involved in the investigation.
‘Parents and students must be able to have faith in the exam system. Any suggestion of malpractice is concerning and should be looked into,’ a spokesman said.
He continued: ‘Cambridge International Examinations board are dealing with the incidents and have made the exam regulator Ofqual aware.’
Tory MP and chairman of the Education select committee, Robert Halfon, described the development as ‘worrying’.
‘To have one example is bad enough but to have two in some one Britain’s top private schools is more worrying,’ he told The Telegraph.
‘Questions need to be asked about whether this is more widespread and whether there is a conflict of interest over this practice.’
