General Mathematics — QLD QCE scaling 2024

QTAC's verbatim 2024 scaling for General Mathematics (QCAA code 0052). Raw median 68/100 mapped to scaled 60.48; top-decile raw 85 mapped to scaled 78.37.

Raw → scaled distribution (2024)

Percentile	Raw mark (/ 100)	Scaled mark (/ 100)	Adjustment
P99	94	85.12	-8.9
P90	85	78.37	-6.6
P75	77	70.72	-6.3
P50 (median)	68	60.48	-7.5
P25	60	50.49	-9.5

How General Mathematics 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 General Mathematics specifically: a median student in the cohort had a raw mark of 68/100 and ended up with a scaled mark of 60.48/100 — an adjustment of -7.5 from raw to scaled. A top-decile student (P90) had a raw mark of 85 mapping to scaled 78.37 — adjustment of -6.6.

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 General Mathematics ↓

Year	Scaled mean (/ 100)
2022	60.97
2023	61.0
2024	60.48

Scaling has fallen by 0.5 points over 2 years (2022: 60.97 → 2024: 60.48). 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 General Mathematics

Subject complexity classification: low — broad tutor supply. Based on our subject-complexity model, this subject typically carries a -4% 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 General Mathematics
University-student tutor	$60/hr
Experienced graduate	$75/hr
Registered teacher	$105/hr
Subject specialist	$135/hr

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 General Mathematics. 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 (50.49 → 78.37, a 27.9-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.
