What it counts: Conditional integer recovery from the HMC inspection's473 entries, 88.4% A/B, 96.6% A–C and100 %pass.
Note: Grouped counts are derived, not printed source counts. Assumptions: the percentages refer to the same473-entry population;88.4 and96.6 use nearest0.1-percentage-point rounding;100 %pass means every entry passed. These imply418 A/B, 457 A–C, 39 C and16 D/E. A versus B and D versus E remain unidentified; no A-only percentage is inferred.
What it counts: Examination grade distribution
Who is counted: Source-specific annual examination population
Publication status: Original inspection percentages; conditional grouped-count derivation
Year: 1997

How the source defines it: Conditional integer recovery from the HMC inspection's473 entries, 88.4% A/B, 96.6% A–C and100 %pass.

A–B: left out of comparisons: covers a different group from the school-wide series; measured differently; unclear which group it counts.
