How ATAR scaling actually works
ATAR · Hayzum editors · 27/08/2026 · Updated 31/08/2026
Scaling exists so students taking different subject combinations can still be ranked against one another. It does not add or subtract marks in the way a teacher might moderate a test.
Each state publishes different public detail. Victoria talks about study scores. NSW talks about scaled aggregates. Queensland uses a different senior system again. The important idea is the same: your contribution depends on the cohort, not only on your raw mark.
Hayzum calculators follow public contribution patterns. They cannot reproduce confidential tables, so treat every scaled figure as an estimate until your tertiary admissions centre issues an official rank.
