  1. In 2020 and 2021, all GCSEs in England have been reformed and use the new 9 to 1 grading system (rather than A*-G). Year on year comparisons will be limited until these qualifications are consistently included from 2020 onwards. However, results for 2020 and 2021 are not comparable with earlier years due to the cancellation of exams (due to COVID-19) and the changes to the way GCSE grades were awarded and results for 2022 are not comparable with previous years due to the changes relating to grading assessments.
  2. 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 This is in line with the announcement that school level data would not be published using either summer 2020 or summer 2021 exam grades awarded. Data is not being supressed in 2022 at local authority or national level.
