A schoolgirl was left "angry and humiliated" after she was kicked out of class for wearing black trousers that were slightly too short.
On Tuesday the Year 11 pupil went to class at George Spencer Academy in Nottinghamshire wearing a pair of M&S trousers that rested a short distance from the top of her shoes.
She was quickly made to leave the class and spend time in exclusion.
While the girl had worn the trousers with no issues last year, the Stapleford school had updated its uniform policy.
Now all trousers have to touch the top of pupils shoes.
The student's dad told the BBC: "They weren't fashion. They weren't ankle grabbers.
"I think she had just slightly outgrown the trousers and they were just a little bit off the top of the shoe.
"That was enough for her to be singled out and put in isolation for the entirety of Tuesday."
He suggested that the blame for the trouser's length should not fall on the student but on the parents.
When approached for comment by the BBC, the school confirmed that its new uniform policy required trousers to be plain and to cover ankles and socks.
The spokeswoman said the school would be happy to discuss the matter further with the girl's father.
The Nottinghamshire student is not the only one to rub up against authority at the start of the school year.
Parents have threatened to protest outside the school gates of Priory School in Lewes, East Sussex after a gender neutral school uniform policy came into force.
Parents have also hit out at a school for taking 120 pupils out of class for wearing the 'wrong' shoes on the first day of term.
Many criticised Ashby School in Ashby de la Zouch, Leicestershire, on social media saying their actions were "totally inappropriate and completely unnecessary".
One mum said she understood policy but it was 'wrong to punish the kids in this way' on their first day back.
