How this SA estimate is calculated
South Australian ATARs are produced by SATAC from SACE Tertiary Admissions Subjects (typically 90 credits of eligible results) with Scaling.
Results are unofficial estimates generated by Hayzum. They are not produced by a tertiary admissions centre.
Actual ATARs change with cohort performance, scaling, and eligibility rules that are recalculated every year.
Always verify with the official authority for your state or territory before relying on a figure for applications.

About SA ATAR calculator
This SA ATAR calculator, reflects a system that's built around credit points rather than a fixed subject count. Where Victoria talks about a primary four, and Queensland requires five general subjects, South Australia's SACE measures your workload in credits, and your ATAR eligibility comes down to reaching 90 credits worth of the right kind of study at Stage 2.
Most Stage 2 subjects are worth 20 credits, though some, like a Research Project, are worth 10, so 90 credits typically works out to somewhere between four and five full subjects, plus a smaller piece of study on top.
Not every SACE subject can be used
The 90 credits that count towards your SA ATAR formula have to come from what's called a Tertiary Admissions Subject, or TAS, a term you'll see a lot once you start looking into SACE ATAR requirements properly. The universities and TAFE SA jointly approve which Stage 2 subjects qualify as TAS. Community Studies, Modified subjects and some local programs fall outside this list, which catches students out if they've built a chunk of their Year 12 study around a subject that was never going to count towards their aggregate.
There's also a rule around precluded combinations, where two subjects considered too similar in content can't both be counted. On top of standard SACE subjects, Recognised Studies, things like an interstate Year 12 subject, certain higher education units, or an approved VET qualification, can sometimes be included as well, which gives students with a mixed study pattern more flexibility than a purely SACE-only pathway would allow.
Results to aggregate
Once your eligible results are in, SATAC converts each one into a scaled score, adjusting for differences in how subjects are assessed and how their cohorts perform, so a result in one subject can be compared fairly with a result in a completely different one. These scaled scores are then combined into what's called your university aggregate, reported on a scale up to 90.00. Rather than fixing exactly which subjects must be included, SATAC works through the different combinations of your results and applies whichever produces your strongest possible aggregate.
Converting your aggregate into an ATAR
Your university aggregate isn't your final answer, it's the input for one more step. SATAC takes that aggregate and compares it against every other student's aggregate across the state for the year, producing a rank between 0.00 and 99.95. This SATAC ATAR calculation is really a translation exercise, turning a subject-based score into a position relative to your entire Year 12 cohort.
What your number is telling you once you have it
An ATAR isn't a grade, and it doesn't map onto a percentage in your head the way a school report might. If your SA ATAR percentile comes back at 85, you've placed ahead of roughly 85 percent of the students in your reference cohort for that year, nothing more specific than that. This is worth sitting with for a moment if your result feels lower than your subject results implied, because your SA ATAR rank reflects the whole state's performance that year, not a fixed pass mark you either clear or don't.
Turning your ATAR into a university place
SATAC doesn't only calculate the ATAR, it also runs the application and offer process for South Australia's universities and TAFE SA. SA university ATAR requirements are published per course and typically reflect what it took to secure a place in the previous intake, which moves depending on demand, so this year's figure is genuinely a starting point rather than a fixed SA ATAR cutoff. Some courses go further and apply their own adjustment factors or Special Entry provisions on top of a student's raw ATAR, adjusting for things like subject prerequisites or personal circumstances, which means the number that actually decides your place can differ from your published ATAR itself. Checking a course's specific entry criteria through SATAC directly is worth the extra few minutes rather than assuming your ATAR alone tells the full story.
What a calculator like this is genuinely good for
Treat any SA ATAR predictor, including this one, as a way to track your progress rather than a source of your final figure. Since scaling and the statewide aggregate comparison both depend on data that only exists once every SACE student's results are confirmed for the year, an SA ATAR estimate produced beforehand will always be an approximation. Where it does help is giving you a realistic sense of how your current subject combination is likely to sit, so you can make informed decisions about your remaining Stage 2 study rather than guessing blind.
FAQs about SA ATAR calculator
How many credits do I actually need for an ATAR?
You need 90 credits of eligible Tertiary Admissions Subjects at Stage 2, along with meeting the general requirements to complete your SACE. Most subjects are worth 20 credits, so this typically means around four to five full subjects.
Does every SACE subject count towards my aggregate?
No. Only subjects approved as Tertiary Admissions Subjects count, and a handful of subjects, including Community Studies and Modified subjects, are excluded from ATAR calculations entirely.
Can results from outside SACE contribute to my ATAR?
Yes, in some cases. Recognised Studies, such as approved interstate subjects, certain higher education units, or VET qualifications, can be included alongside your SACE results if they meet SATAC's criteria.
Why did my ATAR come out lower than my subject results suggested?
Your ATAR reflects a statewide comparison, not your subject results directly. Scaling adjusts each result relative to how its cohort performed, and your final aggregate is then measured against every other student in the state that year, so the outcome doesn't always mirror your marks in isolation.
Is my university aggregate the same as my ATAR?
No. Your university aggregate is a score out of 90.00 built from your scaled subject results, and it's the figure SATAC then converts into your actual ATAR, a separate rank between 0.00 and 99.95.
Who do I contact about my official SA ATAR?
SATAC calculates and issues the official ATAR for South Australian students, and also manages university and TAFE SA applications, so they're the right place to check both your result and any course-specific entry requirements.
