How the QCE ATAR is calculated (2026): QTAC eligibility, scaling and the best-five aggregate

Queensland moved from the OP to the ATAR with the 2020 Year 12 cohort. The rules are different from NSW and Victoria, and a lot of what circulates about them (including "you need a QCE" and "Essential English doesn't count") is wrong. This guide sets out the rules as QTAC publishes them.

Who does what: QCAA and QTAC

QCAA (Queensland Curriculum and Assessment Authority) writes the syllabuses, sets and marks the external assessments, quality-assures school-based internal assessment, and issues your subject results and your QCE.

QTAC (Queensland Tertiary Admissions Centre) takes the subject results QCAA sends it, scales them, and calculates the ATAR. QTAC also runs course applications, preferences and offers.

QTAC is explicit that the QCE and the ATAR are different things with different purposes: the QCE certifies that you have met a standard of senior schooling; the ATAR is a rank used only for tertiary selection.

ATAR eligibility: the actual rules

To be eligible for an ATAR, QTAC requires you to:

1. Complete one of three subject combinations (all at Units 3 and 4):
   • five General subjects; or
   • four General subjects plus one Applied subject; or
   • four General subjects plus one completed VET qualification at Certificate III level or higher.
2. Satisfactorily complete an English subject, meaning a grade of C or better, in one of: English, English as an Additional Language, Literature, English & Literature Extension, or Essential English.
3. Accumulate the results within a five-year period.

Two consequences people often miss:

• Essential English satisfies the English requirement. It is an Applied subject, so it can also be your one Applied input if it is among your best five scaled results.
• Passing English does not mean English counts in your aggregate. QTAC includes your English result only if it is one of your best five scaled results.

How your subject results are produced

General subjects are assessed by three internal assessments (set and marked by your school, then confirmed by QCAA) and one external assessment set and marked by QCAA. According to QCAA:

• In Mathematics and Science General subjects, the external assessment is worth 50% of the subject result.
• In all other General subjects, it is worth 25%.

General subject results are reported as a mark out of 100 (with an A to E grade). Applied subjects have no QCAA external assessment and are reported as A to E grades only. That difference matters for scaling: QTAC scales 100 possible results in each General subject but only five in each Applied subject.

Inter-subject scaling

Scaling exists because a result of, say, 80 is harder to achieve in some subjects than others, depending on how strong the competition in that subject is. QTAC's position is that subjects are not inherently harder or easier; some simply attract a more competitive cohort.

QTAC uses an iterative method. Roughly:

1. Every student gets an initial estimate of overall ability (a "polyrank") from their results.
2. For each subject, QTAC models how raw results relate to the overall ability of the students who took it, and sets a scaled result for every possible raw result.
3. Polyranks are recalculated from the new scaled results, and the cycle repeats until the numbers stop changing.

Scaled results sit on a 100-point scale, to two decimal places. Completed VET qualifications are scaled by AQF level, so every completed Certificate III gets the same scaled result regardless of industry area.

What QTAC's 2025 data shows

QTAC's ATAR Report 2025 publishes, for each subject, the raw and scaled result at several percentiles. At the median (50th percentile) of each subject's own cohort:

For Applied subjects and VET in 2025: a B in Essential English scaled to 19.59 and an A to 38.90; a B in Essential Mathematics scaled to 22.34 and an A to 41.30; a completed Certificate III scaled to 38.00 and a Certificate IV to 51.84.

Read these as "what a middle-of-the-cohort result was worth in 2025", not as a promise for 2026. Scaling is recalculated from scratch every year from that year's results.

From scaled results to an ATAR

1. QTAC adds your best five eligible scaled results to form your Tertiary Entrance Aggregate (TEA), out of a maximum of 500.
2. Students are placed in order of their TEA.
3. QTAC works out how many students belong in each of the 2,000 ATAR bands (99.95, 99.90 and so on) using an estimate of the whole potential Year 12 population (based on Queenslanders aged 16 to 20), not just the students who are ATAR-eligible.
4. Students are allocated to bands from the top down.

QTAC does not publish a fixed aggregate-to-ATAR conversion; it depends on the year's results. Treat any online "aggregate X = ATAR Y" table with suspicion.

Combinations that can't both count

QTAC precludes some combinations from the same ATAR:

• a General English subject and an Applied English subject (for example English and Essential English);
• a General Mathematics subject and an Applied Mathematics subject (for example Mathematical Methods and Essential Mathematics);
• the same subject taken both as a General subject and as a Senior External Examination.

Everything else can count together. English and Literature can both count, as can General Mathematics, Mathematical Methods and Specialist Mathematics.

Adjustment factors are not your ATAR

Institutions can add adjustment factors (formerly "bonus points") to your ATAR to create a course-specific selection rank. QTAC lists equity, subject (for example a language other than English or Specialist Mathematics), location and elite-athlete adjustments as common types. Each institution sets its own rules and caps. Your ATAR itself never changes.

2026 results and offers timeline

The ATAR appeal window runs from release on 18 December 2026 until 31 January 2027. Appeals are only for cases where you believe QTAC did not calculate your ATAR according to its published rules.

Choosing subjects with this in mind

• Check prerequisites first. Most university prerequisites require a General subject at C or better at Units 3 and 4; some ask for a B. Missing a prerequisite rules you out regardless of ATAR.
• Scaling rewards strong cohorts, not hard subjects. A high raw result in a subject you are good at will usually beat a middling result in a subject that scales well. The 2025 table shows a median General Mathematics result scaled to about 60, while a 90th-percentile General Mathematics result scaled to about 77.
• A sixth subject is insurance. Because only the best five count, a sixth General subject, Applied subject or Certificate III gives you a fallback if one result disappoints.
• Don't drop to Essential English purely to "protect" your ATAR. A B in Essential English scaled to under 20 in 2025. If you can pass General English or Literature, it is almost always the stronger input.

To try different subject combinations, use the QCE ATAR calculator. It gives an estimate only, based on QTAC's 2025 subject scaling.
