How is ATAR calculated in QLD?

In Queensland, your ATAR is worked out by QTAC from your scaled QCE subject results. QTAC scales each subject result, takes your best five, and ranks that total against your age group to give an ATAR from 0.00 to 99.95. QCAA sets the subjects and runs the assessment; QTAC turns those results into your ATAR. Queensland moved from the OP system to the ATAR in 2020.

A rank, not a mark

The most important thing to know is that your ATAR is a rank. An ATAR of 85 does not mean you scored 85%. It means you finished ahead of about 85% of your age group.

Because it is a rank, it lets universities compare students who took completely different subjects. That is the whole point of the ATAR.

What the QCE is

The QCE is the Queensland Certificate of Education, the Year 12 qualification in Queensland. Subjects are set and assessed by QCAA, the Queensland Curriculum and Assessment Authority.

You finish with a result in each subject. Those results are the raw material for your ATAR, but they are not your ATAR. That comes next.

How your subject result is built

For a General subject, most of your result comes from internal assessments across the year, set at your school and confirmed by QCAA. The rest comes from an external exam, written and marked by QCAA.

For most subjects the external exam is worth about a quarter of your result. For maths and science subjects it is worth half. So your work across the year carries real weight, long before the exam.

How QTAC scaling works

Once you have your subject results, QTAC scales them. Scaling adjusts each subject so that the same result means the same thing across subjects.

A subject scales up when the students taking it are strong across all their subjects. It scales down when the group is broader. Your position within the subject never changes — scaling only changes how the result counts towards your ATAR.

Your best five results form your ATAR

QTAC takes your best five scaled results and combines them. This can be five General subjects, or a mix that includes an Applied subject or a VET qualification, within set limits.

Your strongest five do all the work. Anything beyond five does not count, so a spare subject is a useful safety net rather than a boost.

The English requirement

To be eligible for an ATAR in Queensland, you must complete an English subject and meet a set literacy standard. This applies to everyone.

However, your English result only counts towards your ATAR if it is among your best five. So English is required for eligibility, but it does not have to be one of your top five results.

A worked example

Say you take English, Maths Methods, Biology, Business and Physical Education. QTAC scales each result and takes your best five.

It combines them into a total, then compares that total with every other student’s. If it sits higher than 88% of them, your ATAR is about 88.00. Your strongest results do the heavy lifting.

Who does what in Queensland

Two bodies are involved, and it helps to keep them straight. QCAA runs the QCE: it sets the subjects, runs the assessment, and gives you your results. QTAC takes those results, scales them, and works out your ATAR.

So QCAA gives you your QCE. QTAC gives you your ATAR. We cover QTAC in detail in QTAC explained.

From OP to ATAR

Queensland used to use the OP, or Overall Position, a band from 1 to 25. It moved to the ATAR in 2020, bringing it into line with the rest of the country.

So if an older sibling talks about their OP, that system is gone. Every Queensland student now receives an ATAR. See ATAR vs OP vs ENTER for the history.

Estimate your QLD ATAR

The clearest way to see all this is to try it. Our QLD ATAR calculator applies scaling to your subject results and gives you an estimated ATAR.

An estimate is not your official result, which only QTAC can give. It shows you where you stand now, so you can set a realistic target for the rest of Year 12.
