How Music Extension (Performance) scaled in 2024

This subject scales up significantly. The average student in this course outperformed the average student across all senior secondary subjects, so the scaling process boosts the cohort's marks. A solid raw mark in this subject is worth more in scaled terms than the same raw mark in most other subjects.

For Music Extension (Performance) specifically: a median student in the cohort had a raw mark of 92/100 and ended up with a scaled mark of 75.73/100 — an adjustment of -16.3 from raw to scaled. A top-decile student (P90) had a raw mark of 99 mapping to scaled 82.73 — adjustment of -16.3.

QCE General subjects are scored 0–100 raw. QTAC's inter-subject scaling runs a 40-iteration calibration algorithm that maps each subject's raw distribution to a scaled distribution based on how that subject's students performed across all their other subjects. The scaled mark is what counts for the ATAR aggregate; the raw mark is what your QCE certificate reports.

3-year scaling trend for Music Extension (Performance) ↓

Year	Scaled mean (/ 100)
2022	80.63
2023	78.95
2024	75.73

Scaling has fallen by 4.9 points over 2 years (2022: 80.63 → 2024: 75.73). 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 Music Extension (Performance)

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.

What this means for ATAR planning

Three reads of this scaling distribution matter for QCE students:

1. The median (P50) shows the typical adjustment for an average performance in Music Extension (Performance). Negative — average performances are scaled down because the candidature underperforms in other subjects on average.
2. The P90 row shows where strong students land. Even in subjects with a low median scaled position, strong individual students typically score well in scaled terms — look at the P90 column before deciding a subject is "bad".
3. The spread P25→P90 (65.65 → 82.73, a 17.1-point spread) shows the room for movement within this subject. Bigger spreads mean tutoring leverage is higher.

Caveats

• This is 2024 data. QTAC recomputes scaling each year.
• QTAC publishes only subjects with 50+ students. Small-candidature subjects are excluded from the percentile tables.
• Applied subjects (e.g., Essential English, Sport & Recreation) use a different scaling scheme (3-band C/B/A) — see the QLD QCE overview for the Applied subject scaling table.
• To be ATAR-eligible in QLD, students need at least a C in English, EAL, Literature, English & Literature Extension, or Essential English. Only 50.1% of the 2024 cohort (28,845 of 57,594) was ATAR-eligible.
