Source: TISC 2026 Course Statistics Summary (26 April 2026). P25–P90 = percentile scaled scores. Mean = average scaled score across all students. Scaling changes each year.
Cut-offs are indicative and change annually. Always verify at tisc.edu.au and your chosen institution's website.
Our 100% accurate WACE ATAR Calculator< uses exact data from the 2025/26 TISC Scaling Report to give Western Australian Year 12 students an accurate estimate of their Australian Tertiary Admission Rank. Enter your scaled course scores (out of 100), and instantly see how your Tertiary Entrance Aggregate (TEA) — including bonus points for Maths Methods, Maths Specialist, and LOTE subjects — converts to a predicted ATAR. Built specifically for WACE ATAR course students across Perth and Western Australia.
The ATAR (Australian Tertiary Admission Rank) in Western Australia is calculated by TISC (Tertiary Institutions Service Centre). Here is how the process works step by step:
A scaled score in WACE is the final mark for your ATAR course after TISC applies its scaling adjustment. Scaled scores run from 0 to 100. The average scaled score across all courses in 2024 was 60. A scaled score at the 90th percentile (P90) means you outperformed 90% of students in that subject. Here are some key reference points from the 2026 TISC data:
WA's ATAR system includes a unique bonus points system that differs from other states. Students who achieve a scaled score in one or more of the following subjects receive bonus additions to their TEA:
These bonuses apply regardless of whether those subjects fall within your best four. A student who scores 70 in Maths Methods and 80 in Maths Specialist — with both in their top four — still receives the bonus on top of the direct contributions. This effectively rewards STEM and language study.
Important: TISC announced in February 2025 that from 2026, the bonus points system will be removed to bring WA into line with other Australian states. Until then, the bonus system applies for students completing Year 12 in 2024, 2025, 2026, and 2027.

To receive an ATAR in Western Australia, you must meet the following requirements:
TISC scales your WACE ATAR course combined scores (50% school assessment + 50% exam). Your best four scaled scores form the TEA. Bonus points of 10% are added for Maths Methods, Maths Specialist, and your best LOTE. The TEA ranks you against all WA Year 12 students to produce an ATAR from 0.00 to 99.95.
The TEA (Tertiary Entrance Aggregate) is the sum of your four best scaled WACE ATAR scores, plus 10% bonuses for Maths Methods, Maths Specialist, and your best LOTE (if applicable). The maximum TEA in 2026 was 430. TISC converts your TEA to an ATAR percentile by ranking you against all eligible students.
Yes. In 2026, students received 10% of their Maths Methods scaled score and 10% of their Maths Specialist scaled score added to their TEA, on top of the subject being in their top four (if applicable). These bonuses will be removed from 2028, when TISC updates the TEA calculation.
Based on 2026 TISC data, Maths Specialist (mean 68.9), Chinese Second Language (mean 70.0), French Second Language (mean 68.1), Japanese Second Language (mean 67.2), Literature (66.0), and Maths Methods (64.5) have the highest mean scaled scores. Maths Applications (55.3) and Health Studies (53.6) have lower means.
Medicine at UWA typically requires 99+. Law and Commerce at UWA often need 90+. Engineering at Curtin generally requires 80+. Many other programs at ECU, Murdoch, and Notre Dame accept from 60 to 75. Always check official cut-offs at tisc.edu.au and your chosen university.
No — this is an independent tool using 2024 TISC percentile data for estimates. TISC's official calculator uses your actual TEA and the current year's conversion table. Actual ATARs depend on that year's cohort performance. Use this tool for planning only, and refer to tisc.edu.au for official results.
