Aerospace Systems — QLD QCE scaling 2024

QTAC's verbatim 2024 scaling for Aerospace Systems (QCAA code 0055). Raw median 67/100 mapped to scaled 66.52; top-decile raw 88 mapped to scaled 87.89.

Raw → scaled distribution (2024)

Percentile	Raw mark (/ 100)	Scaled mark (/ 100)	Adjustment
P99	97	92.67	-4.3
P90	88	87.89	-0.1
P75	79	80.64	+1.6
P50 (median)	67	66.52	-0.5
P25	56	50.2	-5.8

How Aerospace Systems scaled in 2024

This subject scales up. The candidature performs slightly above the cohort median across all subjects, so raw marks are adjusted upward in the scaling process. A typical raw mark scales to a slightly higher scaled mark.

For Aerospace Systems specifically: a median student in the cohort had a raw mark of 67/100 and ended up with a scaled mark of 66.52/100 — an adjustment of -0.5 from raw to scaled. A top-decile student (P90) had a raw mark of 88 mapping to scaled 87.89 — adjustment of -0.1.

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 Aerospace Systems ↓

Year	Scaled mean (/ 100)
2022	69.13
2023	71.43
2024	66.52

Scaling has fallen by 2.6 points over 2 years (2022: 69.13 → 2024: 66.52). 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 Aerospace Systems

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 Aerospace Systems
University-student tutor	$60/hr
Experienced graduate	$80/hr
Registered teacher	$110/hr
Subject specialist	$140/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 Aerospace Systems. Roughly neutral.
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 (50.2 → 87.89, a 37.7-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.
