WACE ATAR Calculator 2026: Estimate Your WA ATAR

Your WA ATAR is a ranking, not a mark, and it comes from one number: your Tertiary Entrance Aggregate (TEA), which is your best four scaled scores plus 10% bonuses for Mathematics Methods, Mathematics Specialist and your best Language other than English. The free calculator below adds up your TEA from the scaled scores you enter and estimates your ATAR using TISC’s 2025 TEA to ATAR table. For example, a TEA of about 270 has matched an ATAR of 90 and a TEA of about 295 an ATAR of 95. It is an estimate, because the real conversion is rebuilt from the whole WA cohort each year.

WACE ATAR calculator 2026

Enter the scaled score (0 to 100) for each ATAR course, and mark whether it is a Language other than English, Mathematics Methods or Mathematics Specialist so the bonus is added. You need at least four scores. If you do not know your scaled scores yet, use the second tool to see what scaled scores a target ATAR needs.

How the estimate works

• The tool adds your best four scaled scores.
• It adds 10% of your Mathematics Methods score, 10% of your Mathematics Specialist score and 10% of your best Language other than English score, even if they are outside your best four.
• It converts the TEA to an ATAR by interpolating between the rows of TISC’s 2025 TEA/ATAR summary table, which TISC publishes for illustration only.
• It will not estimate an ATAR for a TEA below about 178, because that is where our reference table ends.
• Your real ATAR depends on how every WA Year 12 student performs, so treat the result as a guide, not a prediction.

How the WA ATAR is calculated, step by step

1. School mark and exam mark. For each ATAR course your school assessment mark is moderated against your school’s exam results, then averaged 50:50 with your WACE exam mark to give a combined mark.
2. Scaling. TISC standardises the combined marks and scales all courses together so the average across all courses sits at 60. Each course is adjusted for the strength of the students who take it, which is why a high mark in a hard course can scale up and a high mark in an easier course can scale down. Scaling is recalculated every year.
3. TEA. TISC adds your best four scaled scores plus the 10% bonuses.
4. ATAR. Your TEA is ranked against all WA Year 12 students of school-leaving age, then converted to an ATAR from 0.00 to 99.95. An ATAR of 75.00 means you did as well as or better than 75% of that group.

TEA rules at a glance

TEA to ATAR conversion table (2025)

This is TISC’s TEA/ATAR summary table for 2025, shown for illustration only. It lists the minimum TEA needed for each ATAR. The last column is the average scaled score you would need across four courses with no bonuses.

The 2023 table has almost the same shape, for example 268.7 for an ATAR of 90 and 295.2 for 95. That stability is why the estimates are useful, but the 2026 table will not be published until after results come out.

Worked examples

These are invented illustrations, not real students. Notice that the bonus in B and D adds several ATAR points, because the bonus is on top of the best four rather than replacing a score.

Important dates for 2026

Dates can change, so confirm them on the SCSA and TISC websites. You see your WACE exam results in the SCSA Student Portal with your WACE student number, and your ATAR in the TISC portal. Activate your TISC account before results day so you are not locked out when everything is released. Our guide to WA school holidays 2026 and WA public holidays 2026 help you plan the summer around results.

English requirements for university entry in WA

According to TISC, an ATAR English, Literature or EALD scaled score of 50.00 or higher meets the English Language Competence requirement at all WA universities. If you score below 50 you can be invited to sit the STAT in January, and TISC may concede competence for a near miss. Some universities also need a final school grade of C or higher in that English course, and General English meets the requirement at some universities under specific conditions. Check the exact rules for your course.

Why your real ATAR may differ from the estimate

• Scaling changes every year. Your scaled score depends on the strength of the cohort in each course, which nobody knows until after the exams.
• The conversion table changes. We use the 2025 table. The 2026 table is built from this year’s TEAs.
• Interpolation. The tool draws straight lines between table rows, so small errors are likely, especially at very high ATARs.
• Your inputs. If you estimate a scaled score from a raw school mark, the estimate can be several points out. Use real scaled scores from past TISC course statistics where you can, and be realistic.

How to lift your TEA

• Treat the exam as half your mark. Your WACE exam counts for 50% of the combined mark, so practise past papers under timed conditions.
• Focus on your best four courses. Only the best four scaled scores count, so a weaker fifth course matters less than a strong fourth.
• Use the bonuses. If you already study Methods, Specialist or a language other than English, the 10% bonus is automatic.
• Look at the course statistics. TISC publishes statistics for each course, which show how scaling treated it in previous years.
• Plan a backup. Universities have alternative entry pathways and early offers, so a lower ATAR does not always close the door. See our guide to choosing the right university.

Other states and international students

ATARs are comparable across states in principle, but each state’s calculation is different. See our calculators for NSW (HSC), Victoria (VCE), Queensland (QCE) and South Australia (SACE). If you studied overseas, our ATAR to GPA calculator and Gaokao to ATAR guide explain how other results are compared. If you are moving to Perth for study, see the cost of living in Perth guide.

Last checked 19 October 2026. The 2025 TEA/ATAR table is TISC’s illustration, and the 2026 conversion will differ. Exam and results dates are subject to change, so confirm them with SCSA and TISC. This calculator is an estimate for planning, not an official ATAR, and the 2027 rules for the 10% bonuses are still being consulted on. We could not open every SCSA page with our research tools, so some dates come from school and tutoring summaries that match TISC’s published information.
