  1. Total number of entries include pupils who were absent, whose results are pending and results which are ungraded or unclassified.
  2. All schools include state-funded schools, independent schools, independent special schools, non-maintained special schools, hospital schools, pupil referral units and alternative provision. Alternative provision includes academy and free school alternative provision. Since September 2013, general further education colleges and sixth-form colleges have been able to directly enrol 14 to 16 year-olds. 2014/15 was the first year in which colleges have pupils at the end of key stage 4. From 2016 onwards, entries and achievements for these pupils are included in figures as state-funded schools.
  3. Some zero percentages may represent small numbers due to rounding.
  4. z = When an observation is not applicable
  5. In 2014/15, the early entry policy where only a pupil’s first attempt at a qualification is counted in performance measures was extended to all subjects. For the summer 2020/21 results, if a pupil takes the same subject twice in summer 2021 then their best result will count. However, if they take the same subject twice across years then only the first attempt counts - regardless of the grade received.
  6. : = When data is unavailable for other reasons
  7. Figures include attempts and achievements by these pupils in previous academic years where only the best grade in each individual subject is counted per pupil. Where subjects have been combined into a group (e.g. Other Modern Languages) and a pupil has two or more entries, each result in each subject is counted.
  8. In 2017, new reformed GCSEs (which use the 9-1 grade scale) were introduced into secondary school performance tables in a phased approach. Unreformed subjects continued to be graded using the A* to G system. Information on how the 9 to 1 scale and the A* to G scale are different and not directly comparable is available in the secondary accountability measures guidance. In 2020 and 2021, all GCSEs are now reformed and use the 9-1 grading scale.
  9. c = a cell that has been suppressed due to low number of pupils. Suppression was applied where deemed necessary for all data up to 2018/19. For 2019/20, DfE suppression policy changed. For 2020 and 2021 results where a geographical area contains only one school (for example Isles of Scilly) the data for that area has been suppressed. This is in line with the announcement that school level data would not be published using either summer 2020 or summer 2021 exam grades awarded.
  10. Discounting has been applied where pupils have taken the same subject more than once. In 2020/21, only one entry per subject is counted and we count the entry with the highest grade for results received in summer 2021. Previously only the first entry grade would count and this is still the case for any results received before summer 2021. Further information can be found in the secondary accountability guidance. Where pupils have already entered for an exam within the same subject in an earlier year, first entry rules are still being used.
