A Purley secondary school has passed a 'no notice' Ofsted inspection with flying colours.

Harris Academy Purley received an 'outstanding' rating in its first inspection in nearly six years.

Inspectors visited the 1030-pupil school in Kendra Hall Road in September before publishing their findings.

The school's principal, Philip Wheatley, said he was proud of his staff for the hard work done to garner the result.

"I'm delighted that Harris Academy Purley has maintained its 'Outstanding' Ofsted rating and that the inspectors praised the academy's ethos which promotes positive behaviour to support excellent learning," he said.

"I'd like to thank our hard-working staff, students, parents and governors who all play a part in our success.

"Students of all abilities and backgrounds flourish at Harris Academy Purley which is why we are the top school in Croydon for progress."

A letter sent to the school by Ofsted outlined what it was that inspectors found so outstanding.

"During the last two years, greater emphasis has been placed on promoting pupils’ positive attitudes, alongside managing poor behaviour," the letter said.

"Pupils have responded well to this approach, leading to high rates of attendance and good punctuality to lessons."

The inspectors observed students before, after and throughout the school day.

"The vast majority of pupils demonstrate a keen desire to get to lessons promptly and, once arrived, settle down to work quickly.

"Teachers are skilled at ensuring that pupils start learning immediately by setting clear expectations and using effective routines.

"Vigilant staff are quick to spot the very few pupils who have a tendency to dawdle, and provide reminders in a pleasant, yet firm, manner."
