The best performing Bromley school at both GCSE and A-Level was St. Olave's and St Saviour's Grammar School, Orpington.
The school has been one of the best performing in the country for a number of years, and continued to excel.
It finished in the top 20 nationally for results in GCSEs or equivalent, with 100 per cent of pupils achieving five or more A* to C grades.
Eltham College, Mottingham, also achieved 100 per cent in this category.
St. Olave's said: "Naturally we are all delighted with these results - they represent a well-deserved outcome from the hard work of staff and students.
"All of these achievements are particularly rewarding when set against a backdrop of some of the most stringent education funding cuts the school has ever witnessed."
Bromley’s Executive Member for Education, Cllr Stephen Wells said: “It is encouraging to see that once again this year high standards have combined with sheer hard work and dedication from so many students to produce such a pleasing set of GCSE results.”
At A-Level St Olave's again topped the list, with 51 per cent of students achieving 3 A levels at AAB.
However seven schools could only manage 0 per cent in this category, among them Bromley College, which finished in the bottom 200 schools in the country for exam results.
