VCE assessment, explained

VCE ATAR calculator

Enter the study scores you expect (or already have) and get a rough ATAR. It runs VCAA's published aggregate rule over VTAC's own 2025 scaling table — the same numbers VTAC uses, at the precision VTAC actually publishes them.

Scaled scores and the aggregate-to-ATAR table are from VTAC's own 2025 Scaling Report (vtac.edu.au, published 11 December 2025). This calculator applies VCAA's published 4+2 aggregate rule to those numbers. It is an estimate, not an official ATAR — VTAC calculates the real one from scaled scores to two decimal places, not the rounded integers a public report can show, and this tool does not include bonus points, special consideration or any course-specific adjustment factor.

Your subjects

At least one must be English, English Language, Literature or EAL — that's the study that has to be in every VCE ATAR. Leave a row blank if you're doing fewer than six.

Only studies VTAC published a 2025 scaling table for are listed. Applied Computing and Music are each listed as VCAA's own separate Units 3&4 sequences (Data Analytics / Software Development; Composition / Contemporary Performance / Inquiry / Repertoire Performance) rather than one combined row, since each sequence scales differently. A handful of other studies are missing because they're Units 1 and 2 only and never produce a study score.

estimated ATAR, roughly 73–77

* counted as the English-group subject. The ± band exists because the public scaling table VTAC prints rounds each scaled score to a whole number, this calculator has no idea what your school's actual moderated SAC marks or exam results will be, and it doesn't include bonus points or special consideration. Your real ATAR can land a few points either side of this number.

How an ATAR is actually built

The 4+2 rule

Your ATAR is built from six scaled study scores at most: your best English-group subject (English, English Language, Literature or EAL — whichever scales highest, if you do more than one), plus your next three best scaled scores in full, plus 10% each of a fifth and sixth if you have them. Fewer than four scored studies, including an English-group one, and VCAA won't calculate an ATAR at all.

Scaling

Your raw study score (0 to 50) is not what goes into that sum. VTAC scales every study against how the students who took it performed across their other subjects, because a raw 35 means something different in a subject that mostly attracts strong all-round students than in one that doesn't. That's why a raw 35 can scale up past 40 in one subject and down below 30 in another — it isn't a comment on the subject's difficulty, it's a comment on who else sat it.

Moderation, before any of this

The raw study score itself is already the end of a separate process: your teacher's SAC marks are statistically adjusted against your school's exam results before VCAA releases a study score, so the number this calculator takes as input has already been moderated once. How that moderation works is its own guide.

Practise the subjects that move it most

The subjects with the lowest scaled scores above are the ones where a few extra marks change your aggregate the most. StudyDesign AI marks a written answer against the real VCAA criteria for your subject and shows exactly which criterion was missed, so you can see where those marks actually are.
