Mo Tanweer, head of economics and deputy headmaster of academics at the posh school whose alumni include Princes William, Harry and many British prime ministers, left after an investigation by the Cambridge International Examinations Board (CIE), The Telegraph reported.
The embarrassing disclosure emerged after a letter was circulated to Eton students informing them about Tanweer leaving the school, and that a number of students' marks for an economics paper voided due to a "breach of exam security".
It said that Tanweer, who was privy to the practice papers due to his position as an Examiner for the Pre-U Economics course run by the exam board, had broken protocol by sharing the information with other teaching staff.
Subsequently, all Eton students sitting the paper have had their exam marks voided and replaced with a grade they achieved in other tests.
"There is no suggestion that any boy at Eton had done anything wrong, nor is any member of staff at Eton other than Mr Tanweer implicated," he said.
"However, CIE has decided that they cannot accept the marks of any candidate at Eton for this paper because to do so would threaten the integrity of the exam and certification," Henderson said.
He lives in Berkshire with his partner Emily and three- year-old son.
"This is a matter that, as headmaster, I have taken very seriously and Mr Tanweer has now left Eton's employment," said Henderson of the exam security breach.
