How Mathematics Specialist scaled in 2024
This subject scales up. The candidature performs slightly above the cohort median across all subjects, so raw marks are adjusted upward in the scaling process. A typical raw mark scales to a slightly higher scaled mark.
The scaled-score scale in WA is 0–100, with the cohort-wide mean across all subjects sitting around 60 by construction. A subject with a scaled mean above 60 had a candidature performing above the WACE-wide average; below 60 means the average student in this subject performed below the WACE-wide average. Note that this is the scaled mean across the course's candidature, not a measure of conceptual difficulty.
3-year scaling trend for Mathematics Specialist ↑
| Year | Scaled mean (/ 100) |

What this means for ATAR planning
In WA, the Tertiary Entrance Aggregate (TEA) is formed from your best 4 scaled scores, with a 10% bonus added to scaled scores in Mathematics Methods, Mathematics Specialist, and LOTE subjects (highest LOTE only). The maximum aggregate in 2024 was 430.
- Mathematics Specialist scaled to a mean of 68.9 — among the upper tier of WACE subjects.
- If you scored at the P90 of this subject (85.8) and it was one of your best 4, you contributed 85.8 scaled points to your aggregate (or 94.4 with the LOTE/Maths bonus where applicable).
- Strong individual results in subjects with lower scaled means can still produce strong scaled scores — look at the P90 row, not just the mean, before deciding a subject is "weak" for ATAR.
Caveats specific to Mathematics Specialist
- This is 2024 data. TISC recalculates scaling each year.
- WACE scaled scores are NOT directly comparable across states. NSW and VIC use a 0-50 scale; QLD and WA use 0-100. Cross-state comparisons need to be normalised by scale.
- The WACE Maths Methods / Specialist / LOTE 10% bonus applies after scaling, only when the bonused subject is one of your top 4.
