Harrow: Other qualifications and government tables, 2007

Every row: What it counts: source-defined pupils/candidates; not an inferred whole-school denominator Where it’s from: Original publication How the source defines it: Government school-level performance-table population and qualifications, with exact printed definitions.

1. Worth knowing: Original column descriptions are retained as measure names. GCE A/AS and later Level 3-equivalent point scores use changing government rules and scales; they are not A-level-only grade distributions. Pupil thresholds are not entry-grade shares. Blanks and suppression symbols remain unresolved, never zero. Identity: {'LA sort code within LSC': 4, 'LA number': 310, 'Establishment number': 6000, 'Institution postcode': 'HA1 3HP'}. This observation belongs to the 2007 column of the 2008 publication. Later-source versions are kept separately; no revision winner or cross-scale trend is presumed.

1. What it counts: Source-defined KS5 enrolment or trigger cohort as labelled Where it’s from: Original publication Worth knowing: Exact original field descriptions retained. Point-score scales and qualification coverage differ from pure A-level results; no A* percentage or all-pupil denominator inferred. Earlier years are retrospective publication versions. How the source defines it: Government-defined end-of-A/AS-or-equivalent cohort; 16–18 enrolment count is a different population from the trigger group.

1. What it counts: School-return candidates and qualification entries are separate published fields. Subject entries: 170.0 Candidates: 140.0 Where it’s from: Original publication Worth knowing: AS and A-level are kept in different records. No A* zero is invented for pre-2010 A-level or AS-level. ISC is the original publisher of this school-return table. It is a respondent survey, not an independent audit or a complete list of schools. This version is retained alongside school publications; no newer-version preference, denominator repair or reconciliation is assumed. How the source defines it: GCE AS-level excluding General Studies; separately published qualification band counts.
