SACE and NTCET assessment, explained

SACE / NTCET ATAR calculator

NTCET students sit the SACE Board's own subjects and are ranked by the same SATAC table as SACE students — one calculator serves both. SATAC publishes no per-subject scaling data at all, unlike WA, NSW and QLD, so this doesn't take a percentage mark: enter each subject's own scaled score out of 20 (from your predicted grade, a school estimate, or a prior year's Tertiary Entrance Statement) and it runs SATAC's real best-90-credit aggregate rule and its published 2025 aggregate-to-ATAR table.

The aggregate rule (best three 20-credit results in full, plus the best 30-credit flexible-option outcome) and the aggregate-to-ATAR table are from SATAC's own 2025 publications (satac.edu.au). SATAC does not publish per-subject scaling data at all — not even a mean or a distribution, unlike WA, NSW and QLD — so this calculator cannot convert a percentage mark; enter each subject's own scaled score out of 20 instead. SATAC's own ATAR page advises against online ATAR prediction tools; take this estimate as a rough one, not an official ATAR, and it does not model 10-credit subjects, Recognised Studies or special provisions.

Your subjects

Your university aggregate is your best three 20-credit results in full, plus a fourth in full and a fifth at half weight to fill the remaining "flexible" credits — SATAC's own rule, out of 90 total. Raw and Scaled show the same number below: the scaled score you enter is the number the aggregate is actually built from, since SATAC doesn't publish a way to convert a percentage mark into one.

Every general, applied and language Stage 2 subject on this product's SACE picker is listed — SATAC gives no basis to treat any of them differently, since it publishes no per-subject scaling data. 10-credit subjects and Recognised Studies aren't modelled; this covers the standard five-20-credit-subject case.

Subject	Raw	Scaled
English	15	15.0
Biology	15	15.0
Chemistry	15	15.0
Mathematical Methods	15	15.0
Psychology	15	15.0

estimated ATAR, roughly 75–83

SATAC's own ATAR page advises against online ATAR prediction tools — treat this as a rough estimate built from your own scaled-score guesses, not a lookup of a real number. It doesn't model 10-credit subjects, Recognised Studies or special provisions.

How a SACE or NTCET ATAR is actually built

The best-90-credits rule

Your university aggregate is built from 90 Stage 2 credits: your best three 20-credit Tertiary Admissions Subjects (TAS) count in full — 60 credits — and the remaining 30 "flexible" credits come from whatever combination of your other results gives the best possible outcome: a 20-credit subject in full, one or more 20-credit subjects at half their scaled score, one or more 10-credit subjects, or up to 20 credits of Recognised Studies. With only 20-credit subjects, that best outcome is always one more in full plus one more at half.

Scaling

Each subject's scaled score (out of 20 for a 20-credit subject, out of 10 for a 10-credit one) already accounts for how that subject's students performed relative to everyone else — the same principle behind VTAC's, UAC's, TISC's and QTAC's scaling. SATAC is the one authority of the five that doesn't publish how a raw or moderated mark becomes that scaled score, so this calculator asks for the scaled score directly rather than guessing at a conversion it has no data for.

Aggregate to ATAR

SATAC publishes a real aggregate-to-ATAR table every year, rebuilt against that year's cohort and the participation rate of 16-20-year-olds across SA and the NT — this calculator reads the 2025 table directly, the same way the VCE, HSC and WACE calculators read theirs.

Practise the subjects that move it most

The subjects with the lowest scaled scores above are the ones where extra marks change your aggregate the most. StudyDesign AI marks a written answer against the real SACE performance standards for your subject and shows exactly which standard was missed, so you can see where those marks actually are.
