League tables have placed Malmesbury School as the best-performing comprehensive school in Wiltshire and one of the best nationally.
A new benchmark figure gives the percentage of students achieving AAB in academic subjects and the average points per exam entry for A-levels.
In the tables, 66 per cent of Malmesbury School students’ grades were A*-B, meaning more than half of students who went on to study degrees were able to secure places at Russell Group universities.
Headteacher Tim Gilson said: “Rigorous academic teaching and very hard working students are the key to six form success.
“Students work harder than ever nowadays and our staff are always willing to go the extra mile.”
Across all key benchmarks at A-level and GCSE, Malmesbury School saw 64 per cent of students achieving five A*-C grades including English and maths.
