SchoolScoresBest sixth forms in Purley
How this list works. Ranked by average points per A level entry (A* = 60, A = 50, B = 40, C = 30, D = 20, E = 10), averaged over up to the last three years and weighted by the number of A level students 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. Full methodology.
