EXAM results from GCSEs taken last year show a rise across schools in south Bucks.
The Department of Education published league tables showing the performance of English secondary schools in GCSEs.
And in Buckinghamshire Beaconsfield High School came top of the table.
There were 100 per cent of pupils who achieved grades A* to C in English and Maths, 100 per cent achieved five or more A* to C grades and 83 per cent achieved the English Baccalaureate, which is a performance measure.
The measure shows where pupils have secured a C grade or above across a core of academic subjects at GCSE level and enables parents and pupils to see how their school is performing. It is not compulsory.
The top non-selective school in south Bucks was Great Marlow School with 71 per cent with Grades A* to C in English and Maths followed by The Chalfonts Community College with 69 per cent.
Next was Sir William Ramsay in Hazlemere with 68 per cent and 67 per cent of pupils got five or more GCSEs graded A* to C.
Headteacher Mark Mayne said "The results are certainly testament to the dedication of our staff- both the teaching staff and associated staff, the support of parents and the determination of our young people."
He said there have been massive improvements which will continue.
The Misbourne, which has come out of special measures following the appointment of a new headteacher, got 64 per cent in English and Maths with 63 per cent getting five or more.
Princes Risborough was close behind with 63 per cent and 62 per cent. Most of the secondary modern schools all increased their percentage, besides Cressex Community School which kept a level pegging at 46 per cent.
State funded schools nationally get an average of 61.3 per cent achieving Grade A* to C in English and MAths GCSE.
