About this WA ATAR calculator

This tool estimates your WA ATAR. It uses TISC's scaling model. WACE works in a clear way. Each subject mixes your school mark and your exam mark. TISC then scales the result against the state. The calculator adds your best four scaled scores. It also adds bonus points for Maths and a language. That total is your TEA. We turn it into an ATAR. For the full method, see our methodology page.

WA rewards harder subjects with a bonus. You get 10% of your scaled score for Maths Methods. You get it again for Maths Specialist. You also get it for your best language. So these subjects can lift your TEA. But you must do well in them first. A low mark earns only a small bonus.

Only ATAR courses count towards your ATAR. General and Foundation courses do not. They still help you finish your WACE. So check that your subjects are ATAR courses. Got your estimate? The section above shows WA universities. Each course lists its 2025 cutoff. Bonus points and adjustment schemes can lift you further.

TISC sets your real ATAR. It arrives in late December or early January. This estimate gets you close. It cannot be exact yet. Scaling depends on this year's students. That data does not exist until results day. Use this to plan and aim.

WA course standards come from the SCSA, and your official WACE ATAR is calculated by TISC.

WA ATAR — common questions

How is the ATAR calculated in WA?

You get a result in each subject. TISC scales each result against the state. Your best results are added into a Tertiary Entrance Aggregate (TEA). That total is ranked against every student. Your place in that line becomes your ATAR. The ATAR runs from 0 to 99.95.

How do WA bonus points work?

WA adds 10% of your scaled score for some subjects. These are Maths Methods, Maths Specialist, and your best language. You must take the subject to get the bonus. This rewards harder subjects.

Why is my ATAR lower than my marks?

Your ATAR is a rank, not a mark. It shows where you placed against everyone else. Marks show what you scored. The two are not the same. Your marks are also scaled before ranking. So a high average can still give a lower ATAR. This is normal and happens to most students.

How accurate is this calculator before results day?

It uses the real method and the latest scaling data. Most estimates land within a few ATAR points. It cannot be exact yet. This year's scaling is not set until results come out. Use it as a guide, not a promise.

Which subjects scale up the most in WA?

Maths scales best in WA. Specialist and Methods are the top two. Then come Chemistry and Physics. Languages scale well too. A subject scales up when its students are strong across all subjects. But scaling only helps if you do well in that subject.

Does picking high-scaling subjects guarantee a high ATAR?

No. This is the biggest myth about the ATAR. Scaling only helps if you score well. A high mark in a subject you love beats a low mark in a 'high-scaling' one. Pick subjects you can do well in.

What's a good ATAR?

There is no single good number. It depends on the course you want. The middle ATAR is near 70. Above 80 puts you in the top fifth. Above 90 puts you in the top tenth. A good ATAR is one that gets you in.

Can I get into uni with a low ATAR?

Yes. Many courses take ATARs in the 60s and 70s. Bonus points can lift you higher. There are also paths that skip the ATAR. These include TAFE, diplomas, bridging courses and portfolios. A low ATAR is one door, not the only one.

What is the TEA in WA?

The TEA is your Tertiary Entrance Aggregate. TISC adds your best four scaled scores. It can also add your bonus points. The most you can score is 430.

Do all my WACE subjects count towards my ATAR?

No. Only ATAR courses count. General and Foundation courses do not. They help you finish your WACE. Check that your subjects are ATAR courses.

How do bonus points and adjustment factors work?

Bonus points do not change your ATAR. They change your selection rank for a course. You might earn them for your area, your school, or hardship. They can lift your effective rank by 5 to 10 points. Each university sets its own scheme.

What is the highest ATAR? Why not 100?

The top ATAR is 99.95, not 100. The ATAR is a rank in steps of 0.05. To score 100 you would need to beat everyone, including yourself. So 99.95 is the top. It means you are in the top 0.05%.

How is my WA subject score worked out?

Each subject mixes two marks. Half is your school mark. Half is your exam mark. TISC then scales the result against the state.

Do I need English for a WA ATAR?

You must meet a literacy standard. You do this through OLNA or your Year 9 NAPLAN. You do not have to put an English course in your best four.

What is scaling and why does it happen?

Scaling makes subjects fair to compare. Each subject has a different group of students. TISC looks at how that group does across all their subjects. A strong group scales the subject up. A weaker group scales it down. It is about the group, not how hard the subject feels.

Why do different ATAR calculators give different numbers?

Each calculator models scaling in its own way. The exact scaling data is not fully public. So small gaps between tools are normal. Treat every estimate as a guide. Your real ATAR comes only on results day.

What's the difference between my ATAR and my subject marks?

Your marks are scores in each subject. Your ATAR is one rank for all of them together. Marks can sit out of 100. The ATAR runs from 0 to 99.95. One is what you got. The other is where you placed.

Should I enter my predicted or real marks?

Either works in this tool. Before results day, use your best honest guess. Base it on your recent tasks and trials. Do not enter your dream score. The estimate is only as good as the marks you put in.

Does dropping or failing a subject hurt my ATAR?

Only your best subjects count, so dropping one is often fine. You just need enough subjects left. A failed subject can count as a low or zero score. It hurts most when it is one of your counted subjects.

Is my ATAR the same across Australia?

Yes. The ATAR is national. An 85 in one state equals an 85 in another. You can use it to apply anywhere in Australia. You can also use it years later if you take a break.

Can my ATAR change after I receive it?

No. Your ATAR is set once your results are final. It will not go up or down later. You can ask for a check of your marks. The rank itself stays fixed for that year.

When do WA ATAR results come out?

TISC releases WA ATARs in late December or early January. You get yours after your WACE results. TISC shares the exact date in advance.

Where do I get my real WA ATAR?

Your real ATAR comes from TISC. You view it online in your TISC account. Your school and the TISC website show you how to log in.

Why is my friend’s ATAR higher with similar marks?

Subject mix and scaling explain most of the gap. Your friend may take subjects that scaled higher. Or they placed higher within their groups. Near the top, a small mark gap can mean a bigger rank gap. Focus on your own results.

Does this calculator save my marks?

No. All the maths runs in your browser. Nothing is sent to a server. Close the tab and your marks are gone. We cannot see them, store them, or share them.
