SACE ATAR calculator

Enter your SACE or NTCET scaled scores to see how SATAC's rules build your university aggregate out of 90, which subjects count, and the ATAR that aggregate gave in SATAC's 2025 table. Set a target ATAR to see the scaled score your remaining subjects need.

This is an unofficial tool. SATAC calculates your ATAR and says it does not recommend using online ATAR prediction tools. This calculator applies SATAC's published rules and its 2025 aggregate to ATAR table. It cannot predict your scaled scores, and the table for your year will be different.

Your aggregate and ATAR from scaled scores

Add each Stage 2 subject and its scaled score: out of 20 for a 20-credit subject, out of 10 for a 10-credit one. Scaled scores are on your Tertiary Entrance Statement. They are not your grades, and SATAC does not publish a conversion from grades.

Target ATAR (optional)

Set a target and leave a subject's score blank to see the scaled score it needs. Scores you enter stay fixed.

Subject 1
Scaled score for Activating Identities and Futures
-
Subject 2
Scaled score for subject 2
Subject 3
Scaled score for subject 3
Subject 4
Scaled score for subject 4
Subject 5
Scaled score for subject 5

ATAR

An aggregate needs:

60 credits from three 20-credit TAS (a valid pair of 10-credit TAS can stand in for one) (still needed)
90 credits that can count together (still needed)

Data: SATAC, 2025 SACE/NTCET university aggregate to ATAR (published 10 December 2025). Subject rules from SATAC's Tertiary Entrance 2026 | 2027 | 2028 booklet (July 2025) and SATAC's pages on ATAR, Calculating a university aggregate, Recognised Studies, Adjustment Factors and Scaling and Scaling FAQs. Subject names and codes are the SACE Board's. AusGrader is not affiliated with SATAC or the SACE Board, and this is not a SATAC tool. SATAC does not recommend using online ATAR prediction tools. Your official ATAR comes only from SATAC.

How the calculator works

SATAC builds your university aggregate out of 90 from scaled scores. The first 60 credits are your best three 20-credit Tertiary Admissions Subjects, and a valid pair of 10-credit subjects can stand in for one of them. The last 30 credits are the flexible option: another 20-credit subject, half the score of a 20-credit subject, 10-credit subjects such as Activating Identities and Futures, or up to 20 credits of Recognised Studies. The calculator tries every combination the rules allow and keeps the highest, as SATAC does.

It also applies the rules that stop subjects counting: precluded combinations (General Mathematics with Mathematical Methods, for example), counting restrictions such as 20 credits at most from Cross-disciplinary Studies and Integrated Learning, and subjects that are not Tertiary Admissions Subjects. A VET qualification scores the average of your first 70 credits of subjects. If the rules leave fewer than 90 credits, there is no aggregate and so no ATAR.

The aggregate is then read against SATAC's 2025 table, which goes up in steps of 0.05. An aggregate between two steps is rounded down to the step below. That is our assumption, since SATAC does not say how it handles one. Adjustment factors are left out, because they change a selection rank for a course, not your ATAR.

With a target ATAR set, the calculator finds the lowest aggregate in the table that reaches it, then works out the scaled score each subject you left blank needs, with the scores you entered kept as they are. It gives every blank subject the same score per 20 credits (half that for a 10-credit subject) and picks the lowest one that reaches the target under the same rules. Blank subjects that would not be in your best 90 credits are marked not needed.

SATAC does not publish how each subject scales, so the calculator cannot turn grades into scaled scores. For how scaling, the flexible option and the ATAR fit together, read the SACE ATAR guide.
