ATAR scaling calculator
Estimate your scaled study scores and aggregate ATAR using the verbatim 2024 scaling figures from VTAC. Pick subjects, enter your study scores, get your scaled aggregate and the corresponding ATAR.
This calculator uses the official 2024 VTAC scaling figures (scaled mean, SD, and the 20/25/30/35/40/45/50 anchor points). For study scores between anchor points it linearly interpolates. It is an estimate. The actual scaling will be different next year because VTAC recalculates scaling each year based on the new candidature.
NSW (UAC) and QLD (QTAC) calculators are below. Both use percentile-based scaling that we cannot reproduce precisely without your percentile rank — they give you the scaled mean ± SD position for the subject as a rough indicator.
VIC VCE — rough 2024 aggregate indicator
Pick 4–6 study scores (your best 4 contribute to the primary aggregate; English is required). Enter the raw study score (0–50) that you expect.
NSW HSC — scaled-mark indicator
Pick an HSC course; we show the scaled mark at the published mean and at each percentile. Find your expected percentile rank from your school's internal ranking; read across to the scaled mark.
QLD QCE — scaled position
Pick a QCE General subject; we show the raw & scaled mark at each percentile.
- VIC calculator uses linear interpolation between the published anchor points (20/25/30/35/40/45/50). Real VTAC scaling uses scaling factors that are slightly smoother — differences vs official VTAC will generally be modest near the centre of the distribution but can be larger near the extremes (raw 20 or raw 50), for small-cohort LOTE subjects, and where VTAC's smooth scaling diverges sharply from a straight line. This is an indicator, not a substitute for VTAC's official calculator.
- Study scores below 20 are not estimated. VTAC does not publish anchor points below raw 20, so the calculator returns no scaled value for raw scores under that threshold; supply 20 or above to include the subject in the aggregate.
- VIC LOTE small-language adjustments are not applied.
- NSW and QLD calculators show distributions rather than a single point because percentile-rank scaling cannot be reproduced from a raw mark alone — you need your cohort rank.
- All numbers are 2024 scaling data; 2025 will be different. Treat as indicative.
