A mother has branded her daughter's school "mad" after she was disciplined for going to school without a blazer on the hottest day of the year.
Fifteen-year-old Aimee Dickson, of Armthorpe, Doncaster, was told to go home and collect her blazer by her headmaster at Armthorpe Comprehensive.
Mum Dawn Dickson said her daughter rang shortly after school began to say she was being sent home to get her blazer.
Mrs Dickson said her husband had to take his daughter's blazer into school.
He spoke to the headmaster who said it was school policy for pupils to carry their blazers at all times.
Mrs Dickson said: "He said if they feel it gets too hot they can ask permission to take their blazers off, but they must carry or wear them at all times.
"In this weather it's a bit mad."
School governor Margaret Pinkney said: "It just seems petty to me. We should be using a little common sense because with this heat it's a different ball game. Teachers should be able to bend the rules a little.
"If the weather is like this year after year the school is going to have to have a summer uniform."
Headmaster Nigel Pattinson was unavailable for comment.
