Parents are being asked to sign a “code of conduct” that will stop them slamming teachers on social media whilst controlling what they wear at the school gates.
Around 50 schools in the north east of England want guardians to agree to the rules, which includes a ban on bikinis as they wait to collect their children.
It comes into force through one of the country's biggest academy trusts, the Bishop Wilkinson Catholic Education Trust covering Co Durham, Newcastle and Northumberland.
The code of conduct is thought to be the first of its kind in UK schools.
It comes after teachers expressed their growing concern over the behaviour and influence of parents.
The Times reports that the action has been taken after some mums and dads were seen smoking and drinking in the playground.
The wearing of t-shirts with offensive slogans during pick-up and drop-off times also ruffled feathers.
But some of the more serious accusation came online, teachers being sent abusive messages with one falsely branded a paedophile by a parent, who was later sent a legal letter.
Nick Hurn, chief executive of the trust, said a parent once attemted to punch him - but was so drunk the blow did not connect.
He said: “Parents and children’s behaviour is much worse since the pandemic - there is a breakdown in civil behaviour, courtesy, good manners. Some of the primary heads are getting upset by people turning up in pyjamas, sometimes leaving little to the imagination.
“A minority of parents do not follow the rules of acceptable behaviour. I thought, ‘Why do we not try to create a code of conduct that outlines what our expectations are for our parents?’
“Teachers and pupils are being subjected to abuse on social media, at the school gates, and there is never any consequence. One teacher was branded a paedophile on social media. I thought, ‘This has to stop’.”
Parents have been told to sign the contract in the first week of term ahead of the new school year.
It warns that “persistent concerns or breaches may result in banning the offending adult from entering school grounds and may lead to prosecution”.
Back in 2016, Kate Chisholm, of Skerne Park Primary, wrote to families and carers of youngsters at the school in Darlington for wearing their pyjamas and slippers.
The teacher requests that parents take the time to dress appropriately in daywear which is suitable for the weather conditions.
