Secondary school pupils in Cornwall are among the best behaved in the country, according to a report.
Ofsted Inspectors found behaviour to be "good" or "outstanding" in all the county's 31 schools.
Cornwall is one of only nine authorities in England to receive top marks for the behaviour of students in 100% of its schools.
"Young people in Cornwall have certainly done us proud," Neil Burden, from Cornwall Council said.
Cornwall's results compare with the national average of 78.6%.
Mr Burden, who is the council's cabinet member for children's services, described is as an "exceptional judgement" and paid tribute to the hard work of students, parents, teaching staff and school governors.
Director of Children's Services Trevor Doughty said Cornish schools had worked hard to meet the "more challenging" framework introduced by Ofsted last year.
Ofsted's inspection process to judge behaviour includes pupils' attitudes to learning and their behaviour in lessons, their treatment of others, awareness of each other's needs and their ability and willingness to manage their own behaviour.
David Barton, head teacher of Budehaven School and chair of the Cornwall Association of Headteachers (CASH), said the public recognition was "very welcome".
"Understanding how important it is to respect other people and tolerate differences of opinion are crucial, and learning how to support each other in work and in play are at the heart of our schools' work," he said.
