How WA scaling works
SCSA moderates school assessment against exam results and combines them into a combined mark. The combined marks are standardised, then TISC and SCSA scale them jointly so the average scaled score across all courses is 60. In 2025, 81 courses were examined for scaling, including 22 languages using interstate syllabuses. See how scaling works and WA ATAR bonus changes.
What it takes to be in the top 25% and top 10%
Scaled score at the 75th and 90th percentiles of each course in 2025, with the median for reference.

The middle of the range differs by about 18 scaled points between the highest and lowest courses here. That gap is about who takes each course: Specialist students tend to be strong across all their courses.
Turning scaled scores into a TEA
Four scaled scores of 60 with no bonus make a TEA of 240, which gave an ATAR of 80.90 in 2025. Four at 70 make 280, an ATAR of 92.30. A student at the median of Methods, Chemistry, Physics and English (about 64.8, 63.4, 62.9 and 58.1) has a TEA of about 249 plus a Methods bonus of about 6.5, roughly 256 in total. Use the WACE ATAR calculator for exact figures.
Reading TISC's table correctly
- Scaled scores, not raw marks. These statistics are for scaled scores out of 100 after moderation and scaling.
- Includes all candidates. TISC's course statistics include international and mature-age students.
- Percentiles need numbers. Small courses have no percentiles published.
- The bonus is separate. The 10% bonus is added to the TEA, not to the scaled score shown here.
WACE scaling FAQ
What is the average scaled score in WACE?
60 across all courses after scaling, according to TISC.
Which WACE subjects scale best?
In 2025, Mathematics Specialist, second languages such as French and Japanese, Mathematics Methods, Literature, Chemistry and Physics had the highest means among larger courses.
Does a high mean scaled score mean the course is easier?
No. A high mean reflects strong students in that course. Your own scaled score depends on how you do against them.
What scaled score do I need for university English?
A scaled score of 50 or more in English, Literature or EAL/D met competence in English for all WA universities in 2025. In 2025, 73.8% of English students and 86.5% of Literature students reached 50.
What scaled score puts me in the top 10% of WA English?
About 74.7 in 2025, the 90th percentile scaled score in English.
Is Mathematics Applications bad for the ATAR?
Its median scaled score was 55.5 in 2025, below Methods (64.8), and it earns no bonus. A high score in Applications can still count in your best four, so pick the maths you will do best in.
Which WA course has the most students?
English, with 9,487 students in TISC's 2025 statistics, followed by Mathematics Applications with 7,969.
