�A 12-year-old pupil with a broken arm says he had to sit on his own for a whole day because he did not wear his school blazer during an Ofsted inspection.

Julie Button, of Starmans Close, Dagenham, is furious with Dagenham Park School after her son Robin was isolated for not wearing the full uniform last Tuesday when inspectors visited.

However, she says she had informed the school in writing before the incident that he could not wear it because he cannot fit his plastered arm through the sleeve.

Julie, 46, said: “I thought that common sense would have been shown but it was not.

“He was not even allowed out for lunch – he just got a chicken wrap and a cup of water.

“I went mad at the school – I called them to ask why he was in isolation.

“I was told that the headteacher had stated the day before the inspection that blazers had to be worn.

“But my son was not in school on that day.

“Those people from Ofsted are not that stupid.

“If you look at someone and his arm is in plaster, obviously you’re going to understand why they’re not wearing their full uniform.”

For the following two days of inspections, Robin was made to carry a blazer which was not his own.

Julie said that he had to hand over his Oyster card in return and hand back the blazer to the school at the end of the day.

Julie said: “It’s out of order. We have been told he must minimise the pressure on his arm, but if he is carrying his bag or books in one arm he has to carry the blazer on the other.

“They have so many rules at that school.”

Julie says she is trying to move Robin into another school.

A spokeswoman for the school said: “The headteacher said the issue has been resolved.”
