The Australian Tertiary Admission Rank (ATAR) is a ranking system used in Australia to measure a student's academic performance relative to their peers in the same graduating year. It is a score between 0 and 99.95 and is used by universities and other higher education institutions to determine admission to undergraduate courses.
To get an ATAR, you need at least four scaled scores from ATAR courses. Universities also need you to meet an English requirement, usually through English, Literature or EAL/D.
You can study more than four ATAR courses, but only your best four count in full.
For WACE courses, your school mark is moderated and combined with your exam mark to make a combined mark. That mark is standardised, then scaled so results can be compared fairly across courses. Across all courses, the average scaled score is 60. How much a mark moves depends on the course and the year.
Your best four scaled scores count in full. 10% of your best LOTE, Mathematics Methods and Mathematics Specialist is then added, even if they aren't in your best four. Some course combinations can't both count.
Your ATAR comes from your Tertiary Entrance Aggregate (TEA), which is out of 430. It adds your best four scaled scores and any 10% bonuses. TISC then converts your TEA to an ATAR, which shows your rank against everyone of Year 12 school-leaving age in WA.
It turns each course mark into an estimated scaled score using TISC's 2025 statistics, then adds your best four and any bonuses, following TISC's rules. Your TEA is converted using TISC's 2025 TEA/ATAR table. TISC only publishes scaled scores, so the mark conversion is our own estimate. If you know your scaled scores, switch to that mode for a closer estimate. Scaling changes every year, so treat the result as a guide.
Enter the mark out of 100 you expect in each course, based on your school assessment and your expected exam result. If you already have scaled scores, switch to scaled score mode. Marks can change once they are moderated and standardised, so a mark is a less exact starting point than a scaled score.
Yes. TISC adds 10% of your best LOTE scaled score, 10% of Mathematics Methods and 10% of Mathematics Specialist to your TEA, not your ATAR. TISC proposed removing the bonuses, but has postponed that change until further notice.
No. Your best four scaled scores count, whichever courses they come from. Universities have a separate English requirement. A scaled score of 50 or more in English, Literature or EAL/D meets it for all WA universities, and from 2025 a C grade in one of those courses can also meet it.
No. No more than two maths scaled scores can count, and Mathematics Applications and Mathematics Specialist can't both be used. Methods with Specialist, or Applications with Methods, are both fine.
No. Only ATAR courses can count, which is why General courses aren't in this calculator.
Yes. You can accumulate scaled scores over five consecutive years, but each course only counts once. If you repeat a course, TISC uses your best score in it.
It's a guide, not an official result. Scaling and the TEA to ATAR conversion are worked out afresh each year, so 2025 figures won't match 2026 exactly. Results from scaled scores are closer than results from marks, because turning a mark into a scaled score is our own estimate.
