Four schools from the west of Scotland are in the top five secondaries in the country for fifth year pupils achieving five or more Highers.
Williamwood High in East Renfrewshire takes top spot with 46% of pupils achieving passes in the category.
The authority also takes third and fifth sport - with St Ninian's High on 42% and Mearns Castle High on 34%.
Glasgow's Jordanhill High is second with 45% with Aberdeen's Cults Academy fourth on a 40% pass rate.
East Renfrewshire education convener, Councillor Alan Lafferty, paid tribute to the authority's "phenomenal success" in having three schools in the top five.
"The performance of our schools, right across the board is something for each of us to be proud of," he said.
"It's all the more remarkable when you look back at where we sat 15 or 16 years ago.
"This level of performance wasn't assured and it's through hard work and dedication from our pupils, teachers, education staff and parents that we are where we are today.
"I'd like to congratulate everyone who contributes day in day out across our schools to nurture and develop the young people we can all be proud of."
