A representative for the Lycee Bossuet-Notre Dame school in Paris said the 52-year-old woman, whose name was released only as Caroline D, donned low-wasted jeans, Converse shoes and "elaborate makeup" to pose as her daughter, Laetitia, during the three-hour Bacchalaureat composition exam, The Daily Telegraph, Britain, reported Wednesday.
The representative said the exam observers decided to wait until after the test to confront the woman.
"Intervening during the exam could have disturbed the other candidates, and created a reason to cancel the test for everyone," the representative said.
The woman was confronted by police officers at the end of the exam and escorted from the hall.
Police said the woman, who told investigators she was attempting to help her daughter get high marks, has been charged with fraud and could face three years in prison and a $11,704 fine if convicted.
