This Statistics Report is the fourth in a new series produced by the Research Division at Cambridge University Press and Assessment, using publicly available school performance data from the Department for Education (DfE). The aim of the new series is to provide a continuation of the Statistics Reports that were previously produced using National Pupil Database (NPD) data which has become more difficult and time-consuming to access. This report is focused on the provision of General Certificate of Secondary Education (GCSE) and International General Certificate of Secondary Education (IGCSE/International GCSE) subjects in England in 2019. The data were downloaded from the DfE's "Find and compare schools in England" service, and consisted of Key Stage 4 (KS4) results at a school level in all subjects in schools and colleges in England, as well as school characteristics such as school gender, admissions policy, and the number of disadvantaged pupils at the end of KS4. In this report the level of provision is presented by different school classifications: school type, school attainment, school gender, school size and school deprivation level. However, it should be noted that the analysis is at the simplest level and takes no account of interactions between these classifications.
