People in teaching jobs in London have been targeted by Ofsted's new approach to classroom inspection.

Earlier this academic year, the national regulator announced that it would include details about teachers' attire in its reports and now staff at Acland Burghley secondary school in Camden have been reprimanded.

The Evening Standard reports that after inspectors visited the specialist arts comprehensive, it was decided teachers' "casual" clothes could have a negative impact on the standard of pupils' work.

Ofsted inspector Mark Phillips's letter to the head teacher outlined: "Some staff take your lead and dress in a business-like fashion. However, in other cases, teachers' attire is too casual and does not promote high professional standards or expectations."

"The lack of pride in [exercise] books is mirrored in other aspects of the school environment - for example, in corridors and display boards. Students are not required to wear school uniform."

Ofsted said the school should take immediate action to remedy the appearance of teachers, which would help instill a greater sense of pride in students.

Business teacher Chris Nicol told the Standard it was quite strange, but most teachers now dress in a business-like manner. He said if it does help to improve pupils' grades then why not dress smarter?

However, English teacher Jason Uzzell was not convinced. He said there is no correlation between teachers' dress sense and the way children learn.

"The most important thing is that we focus on results and attitude to learning," he added.

Sir Michael Wilshaw, the head of Ofsted, believes too many trainee teachers are not given any advice on how to dress in the classroom, stating that when he was the head of Mossbourne Academy in Hackney, he would insist on a smart dress code for his teaching staff.
