A father who was ordered by a judge to keep a close eye on his daughter's education has been jailed for six months after she failed a maths exam.
Brian Gegner, of Fairfield, Ohio, was sentenced to 180 days in prison for "contributing to the delinquency of a minor".
His daughter, Brittany, now 18, had a history of school truancy and a judge warned her father to make sure she passed her General Educational Development tests.
Her family said that she passed four of the five parts, except for maths which she has failed several times
