Each factor is a percentile against schools of the same type nationally. Schools with fewer than 80 students are excluded.

Do these rankings include NAPLAN or ATAR results?
Not yet. ACARA does not publish school-level NAPLAN results in bulk, and ATAR results are released by state authorities in different formats. The Success Index uses the measures ACARA publishes for every school so that all schools are compared on identical data. Where a school publishes its own results we link to its website.
