Parents in the UK are to be handed a leaflet warning them they must take responsibility for their child's behaviour at school or face sanctions, Children's Secretary Ed Balls will announce.
And it warns parents they could be barred from school premises if they fail to treat staff courteously.
The leaflet says that every parent must respect their school's behaviour policy and the authority of staff.
"You should help ensure that your child follows school rules and be prepared to work with the school, if need be, to improve your child's behaviour."
It says: "Good behaviour and strong discipline go hand in hand with effective teaching and learning. Teachers cannot teach effectively and pupils cannot learn effectively in classes disrupted by poor behaviour.
"The most important thing you can do to support the school is to send your child to school each day on time, equipped and ready to learn."
The leaflet adds: "You should treat school staff with the same respect you would expect to receive from them. Parents can be barred from school premises if their behaviour is unreasonable, and they can be prosecuted if they break the ban.
"If parents refuse unreasonably to sign up and support the school's behaviour policy, this can be used by schools to support applications to the courts for Parenting Orders. These orders usually require parents to attend parenting classes to help them manage their child's behaviour."
The leaflet will also tell parents how they can expect their school to maintain good behaviour. It comes as Mr Balls prepares to outline steps heads and governors can take to improve behaviour.
He will tell the Labour party conference in Brighton: "Parents want their children to go to an orderly school with a strong head teacher who won't tolerate bullying or disruptive behaviour in the classroom. So we will back head teachers, and expect all parents to back teachers too, so they have the confidence to use their powers to the full so they can get on and teach and all children can learn."
