SACE aggregate to ATAR (SA & NT) - SATAC's 2025 conversion

SATAC converts your SACE/NTCET university aggregate - the scaled scores of your best 90 credits, out of a maximum of 90 - into an ATAR using an official conversion table it rebuilds every year. Below are the anchor points from SATAC's 2025 table: what each aggregate converted to last year.

This is a prior-year guide, not a prediction. Prior-year information cannot accurately predict ATARs for future students. The relationship between the university aggregate and ATAR changes every year and depends on the SA + NT 16-20-year-old population. Indicative of the 2025 curve only, not a prediction. And because SATAC publishes no per-subject scaled scores, you can't build your aggregate in advance - so treat this as how the aggregate maps to a rank, never a forecast of your ATAR.

2025 aggregate-to-ATAR anchor points

The full SATAC table runs in 0.05 aggregate steps (1,801 rows). These whole-number anchors show the shape of the 2025 curve:

University aggregate (/90)ATAR (2025)
90.0099.95
85.0097.65
80.0093.65
75.0088.45
70.0082.20
65.0075.75
60.0069.30
55.0062.95
50.0056.45
45.0050.25
40.0043.60
35.0036.55
30.0027.55

How your aggregate is built

Your university aggregate is the sum of the scaled scores of your best 90 credits - three 20-credit Tertiary Admission Subjects (60 credits, each scored out of 20) plus a 30-credit flexible option. That gives a maximum aggregate of 90.00, which mapped to an ATAR of 99.95 in 2025.

The full mechanics - the flexible option, Recognised Studies, and how SA and the NT are ranked together - are on how the SACE ATAR is calculated.

Frequently asked questions

What ATAR does a SACE aggregate of 80 give?

In SATAC's 2025 conversion, a university aggregate of 80.00 (out of 90) corresponded to an ATAR of 93.65. But the aggregate-to-ATAR relationship is recalculated every year against the SA and NT cohort, so this is indicative of the 2025 curve, not a prediction of your ATAR.

Can I use this table to predict my ATAR?

No. SATAC states plainly that prior-year information cannot accurately predict ATARs for future students - the curve shifts every year with the population. You also can't build your aggregate in advance, because SATAC doesn't publish per-subject scaled scores. Treat the table as a guide to how the aggregate maps to a rank, not a forecast.

What is the university aggregate out of?

Out of 90. It's the sum of your best 90 credits of scaled scores - three 20-credit Tertiary Admission Subjects (scored out of 20 each) plus a 30-credit flexible option. A maximum aggregate of 90.00 converted to an ATAR of 99.95 in 2025.

Does this apply to NTCET students?

Yes. SATAC's table is for 'SACE/NTCET' and ranks SA and NT students together, so the same conversion applies to Northern Territory (NTCET) students.
