VCE ATAR Calculator

How the ATAR is calculated in Victoria

Your ATAR isn't your raw marks — it's a rank that compares you to every other VCE student in the state. There are three steps: VCAA gives each subject a study score out of 50, VTAC scales those study scores, and the scaled scores are added into an aggregate that maps to your ATAR.

1. Study scores (out of 50)

A study score shows how you performed in a subject relative to everyone else who did it — it already accounts for the difficulty of that year's exams through VCAA's moderation. A study score of 30 is the state average; 40+ puts you in roughly the top 9% of that subject.

2. Scaling

Because some subjects attract stronger cohorts, VTAC adjusts every study score up or down so a 35 in one subject means the same as a 35 in another. Subjects like Specialist Mathematics and Latin scale up (a raw 40 in Specialist became a scaled 51 in 2025); subjects with a wider cohort tend to sit closer to neutral. This calculator uses the exact VTAC 2025 scaling figures, so you see your real scaled scores — not a rough guess. For the full mechanism, read how VCE scaling works.

3. The aggregate and your ATAR

VTAC builds your aggregate from your best results, with one rule: an English study must be included. The formula is:

That aggregate is then matched against VTAC's table to give your ATAR — a percentile rank from 0 to 99.95. For 2025, an aggregate of about 135.65 was needed for an ATAR of 80, and about 169.85 for a 95.

What's a good ATAR?

It depends entirely on your course. Most university courses sit between 60 and 85; the most competitive (medicine, law, some engineering) want 95+. The honest answer: a "good" ATAR is one that gets you into the course you want — which is why subject choice and scaling matter as much as raw effort. See our guide on how to get a high ATAR.

Can you calculate a study score from exam marks?

Not reliably — and it's worth understanding why. A study score is a ranking against the whole state, set by VCAA after every exam is marked and moderated. Your raw SAC and exam marks alone can't tell you your study score, because it depends on how everyone else did. That's why this tool takes study scores as the input: it's a study-score-to-ATAR calculator, which is what almost everyone searching for a "study score calculator" actually needs.

How accurate is this calculator?

It's as accurate as last year's published VTAC data allows. Scaling shifts slightly each year with the cohort, and VTAC finalises the official figures in December, so treat the result as a well-grounded estimate. We refresh the scaling tables every year when the new VTAC report is released.
