£120 fine if pupils arrive late to school
The charge doubles to £120 if not paid within 21 days.
Staff hope the move will raise standards at Emerson Valley primary school in Milton Keynes, Bucks, which has been put in special measures by Ofsted.
But mum-of-four Karen West, 34, said the rule, backed by law, was a “nightmare” for parents who have to take kids to different schools.
And dad Kofi Osei blasted: “Lateness is not going to affect my child’s education.”
Pressure group Campaign for Real Education added: “Punctuality is important but fines are a step too far and could undermine relations between school and parents.”
Milton Keynes Council said the decision to fine was up to each school. A second, unnamed school has the same ruling and two fines were issued in the borough last year.
Penalties are already in place for truancy, with a record 10,185 parents hit for £3.7million last year.
