Counts are derived from NESA's published merit lists and exclude students who opted out of publication. The per-student figure divides each year's count by that year's Year 12 enrolment from ACARA's August census, so it is approximate. NSW law does not permit ranking schools by results, so no rank or percentile is shown.
