How Economics 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.

For Economics specifically, the scaled distribution runs from P25 of 25.6 to P90 of 42.3 — a spread of 16.7 scaled points between the bottom and top quartiles of the cohort. That spread is the practical room for movement within this subject: a student who moves from the bottom quartile of Economics to the top decile gains roughly 17 scaled points per unit, which is significant when multiplied across 2 units toward the ATAR aggregate.

The gap between HSC mark and scaled mark at P90 was -3.2. That gap is negative — top-performing Economics students were scaled down in 2024. This is what scaling actually does: it's not a percentage multiplier; it's a candidature-position adjustment.

Year	Scaled mean (/ 50)
2022	31.4
2023	31.2
2024	31.5

Very stable across 3 years — Economics has scaled within 0.1 points of its 2022 value, suggesting its candidature composition is consistent.

Tutor rate context for Economics

Subject complexity classification: high. Based on our subject-complexity model, this subject typically carries a +12% 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.

How to read the distribution

The HSC mark column shows the raw HSC mark you would have needed to sit at each percentile of the Economics candidature in 2024. The scaled mark column shows what that performance was worth toward your ATAR aggregate. The two values diverge because scaling reflects the academic strength of the candidature as a whole — it is not a fixed conversion of raw HSC mark to scaled mark.

The same HSC mark can produce a range of scaled marks (because students with that HSC mark may have different positions in the underlying cohort). This is why UAC publishes a distribution rather than a lookup table.

Caveats specific to Economics

• This is 2024 data. UAC recomputes scaling each year — 2025 figures will move if the candidature mix changes.
• The HSC mark on your transcript is the NESA-reported HSC mark (aligned to course standards). The mark used in scaling is the raw HSC mark, which is not reported to students directly.
• For courses with combined candidatures (English Standard / Advanced / Studies share a common scale via the NESA standards-aligned raw marks), UAC's scaling treats the combined group; per-course reporting is for transparency.
• Use the scaling data to understand the system, not as the only input to subject selection. Subject engagement matters more than scaling pattern at every level except perhaps the very top decile.
