What Is ATAR in Australia? The Complete Explanation
It dictates your university options, causes the most stress in Year 12, and is widely misunderstood. Here is exactly what the ATAR is, how it works, and what it means for your future.
The ATAR stands for the Australian Tertiary Admission Rank It is a number between 0.00 and 99.95 that represents your overall academic achievement relative to all other Year 12 students in your state or territory. Despite what many students believe, it is not a percentage score out of 100 An ATAR of 80.00 means you performed better than 80% of your state’s Year 12 age group—it does not mean you scored 80% in your exams. Universities use this rank to manage admissions and determine who gets offered a place in their courses.
The Core Concept: A Rank, Not a Score
The single most important thing to understand about the ATAR is hidden in its name. It is the Australian Tertiary Admission Rank. It is not the Australian Tertiary Admission Score.
A score measures how many marks you got right on a test. A rank measures where you stand compared to everyone else.
Imagine you run a 100-metre sprint. Your “score” is your time (e.g., 11.5 seconds). Your “rank” is whether you came 1st, 5th, or 80th out of all the runners. The ATAR is your rank. It tells universities: “Out of every eligible Year 12 student in the state, this student performed better than X% of them.”
An ATAR of 70.00 does not mean you got 70% of the questions right on your exams. Because of the way the system is designed, a student who consistently scores 70% raw marks in their subjects will usually receive an ATAR significantly higher than 70.00. Conversely, in highly competitive subjects, a student scoring 85% raw might still get an ATAR below 85.00.
The “Line of 100 Students” Analogy
To truly visualise what an ATAR means, imagine lining up 100 random Year 12 students from your state in order of their total academic achievement. The person at the very front is the highest achiever. The person at the very back is the lowest.
If you are the person highlighted in cyan, there are 19 people in front of you and 80 people behind you. Your ATAR is 80.00. You beat 80% of the state.
This is why the ATAR is so powerful. It allows universities to compare students who studied completely different subjects in completely different states. It doesn’t matter if you did Specialist Maths in Victoria or Physics in Queensland—the ATAR places everyone on the same 100-person line.
ATAR vs. Study Score vs. Scaled Score
One of the main reasons students get confused about what the ATAR is stems from the fact that their final Year 12 results contain multiple different numbers. It is crucial to understand the difference between them.
Raw Score / Study Score
- This is the mark your teacher gives you for your SACs (School-Assessed Coursework) or the mark you get on your final exam.
- In VCE, this is a number out of 50. In HSC, it’s a mark out of 100.
- It only measures your performance in one specific subject.
- Universities do not see this number.
Scaled Score
- This is your raw score after it has been statistically adjusted (scaled) based on how difficult the subject was and how strong the cohort was.
- If you get a 30 raw in a hard subject, your scaled score might go up to a 35. If you get a 30 raw in an easy subject, it might drop to a 28.
- Universities also do not see this number directly.
The ATAR (The Final Output)
- The Tertiary Admissions Centre (like VTAC or UAC) takes all your scaled scores, adds them together to create an “aggregate.”
- They then rank every student’s aggregate in the state from highest to lowest.
- The top student gets an ATAR of 99.95. The next group gets 99.90, then 99.85, all the way down.
- This is the only number universities see.
If you want to dive deeper into the specific mathematical differences between these numbers, our breakdown of the ATAR vs. Study Score vs. Rank explains exactly how they interact.
How Is the ATAR Actually Calculated?
The calculation happens in a highly secure, centralized facility run by your state’s Tertiary Admissions Centre (VTAC in Victoria, UAC in NSW/ACT, QTAC in Queensland, etc.). While you don’t need to do the math yourself, understanding the steps demystifies the process.
Your school gives you marks for SACs (projects, assignments, tests) throughout the year. At the end of the year, you sit final written exams. The system statistically moderates your school marks against your exam marks to ensure fairness across all schools.
Because some subjects are inherently more difficult or taken by stronger students, your scores are scaled up or down. This prevents a student from getting a higher rank just because they chose “easier” subjects.
The TAC adds up your scaled scores from your top subjects. In Victoria, it’s the top 4 English scores (including at least one Unit 3&4 English) plus your next two best subjects (the 5th and 6th count for 10%). In NSW, it’s your best 2 units of English plus your next best 8 units.
Every eligible student in the state is placed on a single list, ordered by their aggregate score from highest to lowest.
The highest aggregate gets 99.95. The system works down the list, assigning ATARs in 0.05 increments based on the percentage of students below that point. If you want to see a simulated version of this process, you can use our step-by-step guide on how to calculate your ATAR.
Understanding the ATAR Scale (0.00 to 99.95)
The ATAR scale has a few unique quirks that confuse students and parents every year.
Why does it stop at 99.95?
- Because it is a percentile rank, it is mathematically impossible to be in the top 100% of a group (you cannot outperform yourself).
- The highest possible reported rank is 99.95, meaning you are in the top 0.05% of the state.
- Even if you get 100% on every single exam, your ATAR will be capped at 99.95.
Why the 0.05 increments?
- With roughly 50,000 to 70,000 Year 12 students in a state, a step of 0.05% represents roughly 25 to 35 students.
- This means an ATAR of 85.00 doesn’t mean you are exactly on the 85% line—it means you are in the group of students ranked between 84.96% and 85.00%.
- This is why multiple students can have the exact same ATAR.
Technically yes, but it is exceedingly rare. In most states, if your aggregate is below a certain threshold (usually equivalent to an ATAR of around 30.00), you simply will not receive an ATAR at all. You must study a minimum number of authorized subjects and meet basic English requirements to qualify for the rank.
What Is a “Good” ATAR?
There is no universal definition of a “good” ATAR because it depends entirely on what you want to do next. A “good” ATAR is simply one that is high enough to get you into the course you want to study.
ATAR 50.00 – 69.99 (Solid)
- Sufficient for many practical degrees, diplomas, and TAFE pathway programs.
- Opens doors to arts, design, some science degrees, and education at various universities.
- A completely respectable achievement that the majority of students fall within.
ATAR 70.00 – 84.99 (Strong)
- Unlocks the majority of standard bachelor’s degrees across Australia.
- Access to business, IT, psychology, nursing, and engineering at many institutions.
- Positions you well in the job market with a wide variety of options.
ATAR 85.00 – 94.99 (Excellent)
- Gives access to prestigious degrees like dentistry, law, and advanced science.
- Secures entry into almost all courses outside of the ultra-competitive health fields.
- Often qualifies students for early entry schemes and scholarships.
ATAR 95.00 – 99.95 (Elite)
- Required for highly competitive direct-entry programs like medicine.
- Virtually guarantees entry into any undergraduate course in the country.
- Puts you in the top 5% of your entire state—a significant academic achievement.

An ATAR of 75.00 is an incredible achievement if it gets you into the teaching degree you have always wanted. An ATAR of 95.00 can feel like a failure if you were aiming for medicine and missed out. Do not let the internet’s obsession with 99+ ATARs distort your perspective on what constitutes success.

When Do You Get Your ATAR?
Because the ATAR requires every student’s exam to be marked, moderated, scaled, aggregated, and ranked on a state-wide level, it takes several weeks after your final exams to calculate.
ATARs are never released during the year. They are always released in mid-December, typically between December 12 and December 20, depending on your state. Victoria (VTAC) is usually first, followed by Queensland, then NSW/ACT and the other states a few days later.
They are released early in the morning (usually between 7:00 AM and 9:00 AM local time) via your state’s Tertiary Admissions Centre portal. For the exact dates for your specific graduation year, check our dedicated guide on when ATARs are released.
Getting your ATAR in December is step one. Step two is changing your university course preferences based on your actual number. Step three is receiving your official university offer, which typically happens in mid-January during the “Main Round” of offers.
Frequently Asked Questions
Key Takeaways
- The ATAR is a rank, not a score. It represents your position relative to all other Year 12 students in your state, measured in percentiles from 0.00 to 99.95.
- An ATAR of 80.00 means you beat 80% of the state. It does not mean you got 80% on your tests. This is the most common misunderstanding among students and parents.
- Universities only see your ATAR. They do not see your raw scores, your school marks, or your scaled scores—only the final percentile rank calculated by your state’s Tertiary Admissions Centre.
- Scaling prevents “easy subject” exploitation. The system adjusts your scores based on the strength of the subject’s cohort, ensuring fairness across all subject choices.
- A “good” ATAR is relative. A 65.00 is excellent if it gets you into your chosen teaching degree. Don’t let social media distort your definition of success.
- ATARs are released in mid-December. They take weeks to calculate due to the complex statistical processes of moderation, scaling, and state-wide ranking.
