QCE ATAR scaling explained

In Queensland, your ATAR is not calculated by simply averaging your raw subject percentages. Subject results are scaled so students across different subjects can be compared on a common ranking scale.

Why scaling exists

Subjects have different cohorts and assessment patterns. Scaling aims to compare achievement across those subjects fairly. A raw mark in one subject may not have the same ranking meaning as the same raw mark in another subject.

What is TEA?

TEA stands for Tertiary Entrance Aggregate. It is based on the best eligible scaled results. Your TEA is then mapped to an ATAR range based on cohort performance.

Why calculators are estimates

Public calculators use historical data and modelling. They can help you explore scenarios, but they cannot guarantee an official ATAR because the official calculation depends on final cohort results and official processes.

How to use scaling information well

Use scaling as a planning tool, not as a reason to avoid subjects you are good at. The best subject is usually one where you can perform strongly and consistently.

For most students, improving a weaker current subject by a few marks is more useful than switching strategies based on rumours about scaling.
