How English as an Additional Language or Dialect scaled in 2024

This subject scales down. The average student in this course performs below the senior-secondary cohort median across all their subjects, so scaling adjusts most raw marks downward. Important nuance: this does not mean strong students in this subject get poor scaled marks — look at the P90 row in the table. Top performers are still rewarded; the cohort-average position is what moves the mean.

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 English as an Additional Language or Dialect ↓

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.

• English as an Additional Language or Dialect scaled to a mean of 53.7 — below the WACE average.
• If you scored at the P90 of this subject (71.4) and it was one of your best 4, you contributed 71.4 scaled points to your aggregate (or 78.5 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 English as an Additional Language or Dialect

• 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.
