Families have reacted with fury to a strict school uniform policy which they say is "unfair".
Carol Close was furious when her son was removed from the classroom at Walbottle Campus in Newcastle one morning - over his shoes. The school later confirmed the shoes did not break the dress code.
School staff say they're trying to do the best for their students by creating a "culture of high standards". The teachers say financial help will be offered to parents who request it to buy correct items of uniform.They say expectations were "clearly set" before the crackdown after the half term holiday.
But parents have been left outraged as they claim children who break the rules are being separated from their classmates and set work to do quietly in the school hall for the whole day.
Paul Gibson, 14, was punished for shoes his family said they'd bought after reading the uniform guide and checking them against the examples on offer.And his family claims Paul has been wearing the footwear without any issue since the start of the year.
Paul said: "I'm really annoyed - I feel I was wearing the correct shoes and I'm getting pulled up because they say they have some stitching on that they say breaks the code.
"They're just normal black shoes. We're being taken out of class and put in the hall, we're not getting the same lunch or break as our friends - it's affecting our education. It's unfair to be honest."
Meanwhile, Adrian Holling said his son Connor had fallen foul of the rules thanks to a pair of plain black Marks and Spencer trousers.He said: "First they were getting picked up on shoes, now it's trousers. Their education is at stake.
"They are just being put into a hall and told to do their work - but they're only doing English, maths and science, what about his other subjects?
"Connor came down to school this morning in trousers he's been wearing since September and he was punished for it. He's had enough of it. He's an A grade student and I don't think his uniform comes into it. Do the teachers all wear the same uniform and the same shoes? No.
You go there to learn but when you're doing well at your learning but they're picking at little aspects of the dress code, when kids are getting excluded from learning because their footwear or trousers are slightly wrong, that's totally, totally wrong."
Adrian says he's worried about the impact this will have his 15-year-old son as he gets set to take his GCSEs in the summer.
However, school leaders continue to defend the policy.
Headteacher Kerry Lord said:
"We have clearly set out our uniform expectations to parents/carers and students via several letters home (including visual examples), telephone calls, assemblies in school and through our school website."Academic excellence is at the heart of every decision we make. We believe that our culture of high standards and high aspirations leads to high outcomes for students.
"Our school uniform promotes our core values of respect, ambition and determination and it is our expectation that all students arrive at school appropriately dressed, ready to learn and take pride in their appearance, helping to prepare students for life after school.
"After careful consideration, we advised students and parents/carers that we would take action after the half-term break to ensure our high standards were met.
"Students who are not in the correct school uniform are being educated separately in year groups by our senior leadership team and are being reintegrated into the whole school community as soon as they adhere to the rules.
"We are working very hard to remove any financial barriers preventing students from adhering to these guidelines and are assisting affected parents/carers to purchase correct uniform."
