Notes and original wording (4)

What it counts: Source-defined KS5 reporting cohort; published qualification aggregate.
Note: Qualification as printed: Advanced Extension Award. Source symbols (including Supp and NA) are retained. Missing grade rows are unknown, not zero. Subject entries are not a pupil denominator. This government reporting cohort is separate from the school’s summer results publication. The reporting year identifies pupils completing advanced/16–18 study in 2024/25; eligible achievements from up to three years ending 2024/25 may be included. Subject discounting was not applied, so repeated examinations can both appear. The source’s exam cohort is “Other academic”, a headline attainment measure category; the qualification remains separately identified. This is the source-published qualification aggregate. It overlaps the subject tables and must not be added to them or used to infer suppressed subject cells. The aggregate includes a row literally labelled Supp; its category meaning has not been established, so it is not treated as an attainment grade. Printed grade structure: D,M.
