SACE Scaling Explained (SA, 2026)
South Australia has no public SACE scaling table. SATAC scales every Stage 2 subject before it counts towards your ATAR, but — unlike NSW, Queensland and WA — it does not publish per-subject scaled scores. So any “SACE scaling” ranking you see online is a third-party estimate, not official data.
What SATAC actually publishes
SATAC scales your Stage 2 results so that a result in one subject can be compared fairly with a result in another, then adds the scaled scores of your best 90 credits into a university aggregate. The one dataset it publishes is the annual aggregate-to-ATAR conversion table — how a finished aggregate (out of 90) maps to an ATAR — not how any individual subject scaled. See how the SACE ATAR is calculated for how the aggregate is built.
Why there's no per-subject scaling table
SATAC's scaling FAQ puts it plainly. Asked “Can SATAC tell me the scaled scores for a particular subject?” it answers:
“No. Scaled scores for individual subjects are not publicly available.”
You still see your ownscaled score for each subject on your Tertiary Entrance Statement when results are released — you just can't look up a scaling table for every subject in advance the way you can in the other states.
What this means for choosing subjects
Because there is no published per-subject data and the scaling is recalculated every year, you can't reliably pick subjects to “scale up” in SA. The reliable strategy is the ordinary one: choose subjects you're genuinely strong in and that satisfy your intended university course's prerequisites. A subject you score well in will do more for your aggregate than a reputedly high-scaling subject you struggle with.
