Classification date and definitions

Independent schools are shown as Selective here because they set their own admissions criteria; this site convention does not confirm academic entrance tests. School sectors and other admissions labels follow the GIAS register snapshot of 18 October 2026, not necessarily the exam year. Non-Selective refers to the main school intake and does not rule out partial selection or sixth-form entry requirements. Classification sources.

How these figures are calculated

Entries count each course entry once, including Combined Science; they are not unique pupils. GCSE percentages assess each grade separately, including both grades of a double award. Rates use only fully published distributions. Missing or suppressed values are never treated as zero.

England samples match the year and subject; GCSE samples also match the school type recorded in that year. They are not official national averages. Results reflect subject mix and entries, and do not measure teaching quality or value added.
