Teachers must stop trying to wrap children in cotton wool with over-the-top health and safety policies, the chief inspector of schools has said.
Writing in the Sunday Telegraph, Amanda Spielman said it stopped the children developing resilience and grit.
She wants the education watchdog Ofsted to prepare new guidance for schools inspectors in England.
Ms Spielman said making pupils wear high-vis vests on trips made them look like mini-builders minus the hard hats.
She said schools had developed an over-cautious culture that made it difficult for young people to cope with everyday events.
It's about time some sort of common sense was brought back into letting children take the odd risk. This protectionism probably has its roots partly in little Wayne tripping over and Mummy and Daddy demanding thousands in compensation. But we should let kids be kids, climb, run, jump etc. even if they do get a bruise or two otherwise we are simply creating a nation of wimps who will need Health and Safety courses to learn the best way to put their shoes on without injury.
I do like the lady's sense of humour though - Ms Spielman said she looked forward to seeing more eager young faces on trips in the next school year but hopes "fewer of them will be auditioning for Bob the Builder".
