Questions
What is the best secondary school in Buckinghamshire?
On exam results over the last three years, Dr Challoner's High School is the top-ranked secondary school in Buckinghamshire, in the top 1% of schools in England.
How are the schools ranked?
By published Department for Education exam results averaged over three years: for secondary schools, Attainment 8 plus a quarter of the share getting grade 5+ in English and maths; for primary schools, the share reaching the expected standard in reading, writing and maths plus half the share reaching the higher standard. The order uses the three-year average, so a school can rank above one with a higher single-year result. Schools with fewer than 10 pupils taking the tests are not ranked. Exam results are only part of the picture: visit, read the Ofsted report and check admissions rules, as living nearby does not guarantee a place.
