There is no official ATAR to GPA conversion. An ATAR ranks you against other Year 12 students. A GPA shows how you do at university. The two measure different things. So many students’ GPAs differ from their ATAR.
Here is a very rough guide. A high ATAR (95+) often maps to a Distinction GPA (6.0+). An ATAR around 85 maps to a Credit-to-Distinction range. An ATAR around 70 maps to a Credit range. This tool uses that kind of mapping. The honest takeaway is simple. Your ATAR opens the door. But your GPA is earned at university.
How a university GPA actually works
Most Australian universities use a 7-point GPA scale. A High Distinction is worth 7. A Distinction is 6. A Credit is 5. A Pass is 4. A fail is 0 or 1. Your GPA is the average of these grade points across every subject. Each subject is usually weighted by its credit points.
This is why your ATAR and your GPA can look so different. Your ATAR is a rank set on one day, against one cohort. Your GPA is built up over years of assignments, exams and group work. A student who struggled in Year 12 can top their degree. A student with a near-perfect ATAR can find first year hard.
Want the real number instead of a rough guide? Use our GPA calculator once you have results. If your university reports a WAM instead, the WAM calculator does that sum. To plan the other way, the ATAR predictor turns scaled scores into an ATAR estimate. For how the ATAR itself is built, the UAC website sets out the official method.
