How the figure is calculated

The number of entries at or above the band, across every exam system, divided by all the entries. We never average two percentages.

High grades: GCSE/IGCSE A*–G A*–A 813 + GCSE/IGCSE 9–1 9–7 427 = 1,240 of 1,274 entries
Top grades: GCSE/IGCSE A*–G A* 693 + GCSE/IGCSE 9–1 9–8 398 = 1,091 of 1,274 entries
C/4+: GCSE/IGCSE A*–G A*–C 839 + GCSE/IGCSE 9–1 9–4 427–435 = 1,266–1,274 of 1,274 entries (99.4–100.0%: the school’s rounding leaves this much room)
Grade 9: GCSE/IGCSE 9–1 9 68.74% of 435 entries, as printed
