How Mathematics Methods scaled in 2024

This subject scales close to neutral. The candidature performs around the senior-secondary cohort median, so raw marks and scaled marks track each other closely. Scaling is not a major factor either way for this subject.

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 Methods ↓

Year	Scaled mean (/ 100)
2023	64.9
2024	64.6

Scaling has fallen by 0.3 points over 1 year (2023: 64.9 → 2024: 64.6). This typically reflects a weakening candidature — the average student in this subject is performing relatively less well in their other courses than they used to.

Tutor rate context for Mathematics Methods

Subject complexity classification: medium. Based on our subject-complexity model, this subject typically carries a no uplift adjustment to the base AU tutor rate band — partly because of the qualified-tutor pool size, partly because of subject-specific marking and exam complexity.

Tutor tier	Typical rate for Mathematics Methods
University-student tutor	$60/hr

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 Methods scaled to a mean of 64.6 — above the WACE average.
• If you scored at the P90 of this subject (81.2) and it was one of your best 4, you contributed 81.2 scaled points to your aggregate (or 89.3 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 Methods

• 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.
