Cornwall is beating the national average with more than 80% of children attending good or outstanding secondary and primary schools.
According to the latest report from schools inspection service Ofsted, 82% of children are attending top secondary schools, compared to 75% nationally.
Meanwhile, 80% are attending good or outstanding primary schools, compared to 77% nationally.
The findings, which place Cornwall among the top half of local authorities in the country, have been welcomed by Andrew Wallis, the council's cabinet member for children and young people.
"The council works closely with headteachers and governors at all schools to ensure that children in Cornwall are provided with the best possible quality of education," he said.
"It is good to see that more than 80% of our children are attending good or outstanding schools and I would like to thank governors, headteachers and staff for their hard work."
Mr Wallis said the council and schools had no intention of resting on their laurels and new initiatives had been launched to improve standards further.
He said: "While I obviously welcome this report, there is no room for complacency."
