Each score below is shown against the national average — Schools360’s own calculation across the private and independent schools in this dataset with a result at that year level and domain, not a figure ACARA itself publishes, and not every Australian school ACARA tracks. It rests on a single year’s cohort, not a stable multi-year pattern.
