SchoolScoresBest secondary schools in Buckinghamshire
How this list works. Ranked by the percentage of pupils achieving grade 5 or above in both English and maths GCSE, averaged over up to the last three years and weighted by the number of pupils each year. Only years with at least 10 pupils count, and a school needs at least one such year to be ranked. Independent schools, special schools and alternative provision are not ranked because their results aren't comparable. Ofsted outcomes are shown alongside but are not part of the ranking.
