Quick answer: The ATAR (Australian Tertiary Admission Rank) is a percentile rank between 0.00 and 99.95, increasing in 0.05 increments, that compares your overall Year 12 academic performance against your state-wide cohort. It is a rank, not a percentage score — and it is calculated by UAC, VTAC, QTAC, TISC, SATAC or TASC depending on the state you sit Year 12 in.
The ATAR is the single number Year 12 students in most Australian states receive at the end of school, and it determines eligibility for almost every undergraduate university course in the country. Despite that, a lot of how it actually works — what counts as a "good" ATAR, whether Year 11 results matter, why the highest possible rank is 99.95 (not 100) — is less obvious than it should be. The 10 facts below answer the questions Year 12 students and their families ask most often.
What is the ATAR?
The ATAR is the Australian Tertiary Admission Rank — a rank between 0.00 and 99.95 that places your overall Year 12 performance in order against your state's eligible Year 12 cohort. An ATAR of 80.00 means you performed better than 80 per cent of the cohort that started Year 12 in your state. The University Admissions Centre (UAC) explains that the rank is designed so universities across Australia can compare students from different schools, subjects and even states on a single fair scale.
Importantly, the ATAR is a rank, not a score. Two students with raw marks of 80 in different subjects can finish on very different ATARs because of scaling — and two students with very different raw mark profiles can finish on the same ATAR. The number you see on results day reflects your relative position in the cohort, not the marks you wrote on each exam.
How is the ATAR calculated?
The ATAR is calculated on a percentile basis, increasing in increments of 0.05. While the exact process varies by state, the four steps are consistent:
- Raw scores. You receive a raw mark for each Year 12 subject from internal assessments and external exams.
- Scaling. Raw scores are scaled to account for the relative strength of the cohort taking each subject — high-scaling subjects like Specialist Mathematics typically see scaled marks rise above the raw, while subjects with weaker cohorts can see scaled marks fall below.
- Aggregation. Your scaled scores from your top contributing subjects (usually four to five, depending on the state) are summed into an aggregate.
- Ranking. Your aggregate is positioned on a state-wide curve to produce a percentile rank — the ATAR.
For a deeper walk-through of the maths, see our explainer on how the ATAR is calculated.
How does ATAR calculation differ by state?
Each state runs its own Year 12 system and tertiary-admissions centre, so the inputs to the ATAR look different even though the output (a 0.00–99.95 rank) is the same:
- New South Wales: Calculated from the Higher School Certificate (HSC). The University Admissions Centre (UAC) handles subject scaling.
- Victoria: Based on Victorian Certificate of Education (VCE) study scores. The Victorian Tertiary Admissions Centre (VTAC) runs the statistical scaling and produces the ATAR.
- Queensland: Calculated by the Queensland Tertiary Admissions Centre (QTAC) from QCE internal assessments and external exams. Queensland transitioned from the Overall Position (OP) to the ATAR in 2020.
- Western Australia: Derived from Western Australian Certificate of Education (WACE) results. The Tertiary Institutions Service Centre (TISC) handles the scaling.
- South Australia & NT: Run by SATAC, using SACE Stage 2 results.
- Tasmania: Run by TASC, using the Tasmanian Certificate of Education.
- ACT: Calculated through the ACT Board of Senior Secondary Studies (BSSS) using a moderated school-based assessment system, then converted to an ATAR.
Although the underlying calculations differ, every ATAR — no matter the state — is treated as equivalent by Australian universities at admissions time.
What is considered a good ATAR?
A "good" ATAR is the rank that gets you into the course you want to study — not a fixed number. For a Year 12 student aiming at a competitive course like medicine, law or actuarial studies at a Group of Eight university, a good ATAR usually sits above 95.00. For a teaching, nursing or business degree at a regional university, a good ATAR might sit between 65.00 and 80.00. And for a TAFE pathway or a course with portfolio-based entry, the ATAR matters far less than the work you submit.
The most useful first step for any Year 12 student is to look up the most recent guaranteed entry ATAR for the courses on their shortlist (each university publishes these), and to add a 2–4 point buffer for adjustment factors.
How important is your ATAR really?
For most undergraduate courses, your ATAR is the single biggest input into whether you receive an offer — but it is not the only one, and it is not permanent. Universities increasingly use adjustment factors (subject-based, location-based, equity-based) that can lift the rank used in selection. Many courses also offer alternative entry pathways: portfolio entry, interview-based selection, bridging diplomas, mature-age entry after a year of TAFE, and inter-institutional transfers after first-year results.
It also fades quickly. By the time you graduate from a Bachelor's degree, almost no employer will ever ask for your ATAR again — your university results, internships and your final degree do the work. Treat the ATAR as the door to the first room of your tertiary education, not as the verdict on your career.
What is the average ATAR?
The median ATAR awarded each year sits around 70.00. This number is higher than it intuitively feels, because the ATAR is calculated against the full eligible Year 12 cohort in each state — not only against the students who actually finish Year 12 with an ATAR. Students who leave school early, take vocational pathways, or don't complete enough scoring subjects are still counted in the denominator.
So an ATAR of 70.00 places a student in the top 30 per cent of the eligible cohort, but only roughly the top 50 per cent of students who actually receive an ATAR on results day. This is also why the median ATAR is around 70 rather than 50 — about a third of the cohort doesn't end up with an ATAR at all.
Is it hard to get an ATAR above 85?
An ATAR of 85.00 places you in the top 15 per cent of the state cohort, or roughly the top 25 per cent of students who actually receive an ATAR. It is genuinely an impressive rank — but it is achievable for any motivated student with consistent study habits, well-chosen subjects, and structured exam preparation across the Year 12 year. For practical strategies, our guide on how to achieve your dream ATAR walks through what 85+ students typically do differently from 65–75 students.
How many students achieve an ATAR of 99 or above?
Students with an ATAR of 99.00 or above sit in the top 1 per cent of the state cohort. In rough numbers each year:
- Large states (NSW, VIC, QLD): approximately 500 students per state.
- Smaller states (WA, SA, TAS): approximately 100 students per state.
- ACT: approximately 40 students.
The very highest possible ATAR is 99.95 — and the cohort that achieves it is small (typically only a few dozen students nationwide). The reason it is 99.95 rather than 100 is mathematical: a 99.95 rank means you placed in the top 0.05 per cent. There is no rank above 99.95 because there is no fraction of the cohort smaller than that increment.
What's the highest possible ATAR, and why is it 99.95?
The highest ATAR ever awarded in Australia is 99.95. The rank scale moves in increments of 0.05 percentile points and tops out at 99.95 because nobody can be ranked above the top 0.05 per cent of their cohort. The minimum reported ATAR is 30.00 — students whose aggregate would produce a rank below 30.00 simply receive a "less than 30.00" notation rather than a specific number.
Every year, a few hundred students nationwide score 99.95. They aren't necessarily the students with the highest raw marks in every subject — they are the students whose aggregate across their best subjects, after scaling, sits in the very top sliver of the curve. This is why students aiming for the highest ranks often choose a subject mix that combines a high-scaling subject (like Specialist Mathematics or a language) with subjects they can comfortably top.
Do Year 11 subjects count towards your ATAR?
For most students in most states, the answer is no — the ATAR is calculated almost entirely from Year 12 results. The two practical exceptions are: (1) Year 11 students who accelerate a Year 12 unit (for example, completing VCE Unit 3/4 in Year 11) and have that result counted in their final aggregate, and (2) some Queensland and ACT students whose moderated Year 11 internal assessments feed into the system.
That said, Year 11 isn't wasted. The content you cover in Year 11 is treated as assumed knowledge in Year 12, and a strong Year 11 builds the study habits, the subject confidence, and the assessment technique that determines how well you handle Year 12 internals and exams.
Is the ATAR rank equivalent across states?
Yes. Although each state calculates the ATAR through its own tertiary-admissions centre, every Australian university treats every ATAR as equivalent for admissions purposes. A 95.00 from Western Australia, a 95.00 from Queensland, and a 95.00 from New South Wales all sit at the same point in the rank order and qualify for the same selection rank at any university in the country.
Students completing other senior-secondary qualifications — like the International Baccalaureate (IB) Diploma — receive a "notional ATAR" through a published conversion table maintained by UAC, and this notional rank is treated identically to a state-issued ATAR.
What's the difference between ATAR, ENTER and OP?
You'll still see the older terms in Year 12 conversation. Here's the simple translation:
- ATAR: The current national rank, used in every state since Queensland transitioned in 2020. Range: 0.00–99.95.
- ENTER: The "Equivalent National Tertiary Entrance Rank" used in Victoria until 2009. The ATAR replaced the ENTER from the 2010 cohort onwards.
- OP (Overall Position): Queensland's pre-2020 system. OPs ran on a 1–25 scale (with OP 1 being the highest band). Queensland Year 12 students from 2020 onwards receive ATARs through QTAC instead.
If a parent or older sibling refers to "their ENTER" or "their OP", they're describing the same concept — a rank used to enter university — under an earlier name. Universities still recognise these older ranks for mature-age applications.
How can I get a high ATAR?
There is no single fact that lifts an ATAR — it is the product of consistent work across the Year 12 year. Students who finish in the top 15 per cent typically do these things:
- Choose subjects strategically. Pick subjects that align with your strengths and your university course prerequisites. A high-scaling subject can lift your aggregate, but only if you can sit comfortably in its top half — high-scaling subjects don't help if you finish in the bottom of the cohort.
- Stay consistent across the year. The students who score above 90 are almost never the students who started studying in October. They're the ones who maintained 1–2 hours of focused study every weeknight from Term 1.
- Practice past papers earlier than feels comfortable. Doing past papers under timed conditions from the start of Term 3 (rather than Term 4) reliably lifts exam marks by training pacing and question recognition.
- Master exam technique alongside content. Knowing the subject is necessary but not sufficient — students lose ranks to slow handwriting, misreading marking schemes, and poor essay structure rather than poor content recall.
- Get help on the topics you avoid. Working with a Year 12 specialist tutor on the topics you privately know are weakest is one of the highest-leverage uses of study time. Tutoring with a senior-school subject specialist starts from A$65/hr with Tutero, with no contracts.

Frequently asked questions about the ATAR
Is the ATAR a percentage or a rank?
It's a rank, not a percentage. An ATAR of 80.00 doesn't mean you scored 80 per cent on anything — it means you performed better than 80 per cent of your state's eligible Year 12 cohort.
Do all Australian states use the ATAR?
Yes — every state and the ACT now uses the ATAR. Queensland was the last to transition, replacing the OP with the ATAR for the 2020 Year 12 cohort onwards.
What does ATAR stand for?
Australian Tertiary Admission Rank.
What's the lowest ATAR you can receive?
The lowest reported ATAR is 30.00. Students whose aggregate would produce a rank below 30.00 receive a "less than 30.00" notation instead.
The ATAR is a starting line, not a final score
The ATAR gives Australian universities one fair, comparable measure of school-leaver performance — and that's a useful thing for selection. But it does not define a student's potential, lock in a single career path, or close other doors. Bridging diplomas, portfolio courses, vocational pathways, and mature-age entry all lead to the same university degrees and the same careers. Understanding how the ATAR is calculated, what counts as "good" for the courses on your shortlist, and how to plan strategically across Year 12 is what turns the rank from an anxiety into a tool. Every Year 12 student deserves that clarity — and a study plan that earns the rank they're aiming for.

Is it hard to get an ATAR above 85?
An ATAR of 85.00 places you in the top 15 per cent of the state cohort, or roughly the top 25 per cent of students who actually receive an ATAR. It is genuinely an impressive rank — but it is achievable for any motivated student with consistent study habits, well-chosen subjects, and structured exam preparation across the Year 12 year. For practical strategies, our guide on how to achieve your dream ATAR walks through what 85+ students typically do differently from 65–75 students.
How many students achieve an ATAR of 99 or above?
Students with an ATAR of 99.00 or above sit in the top 1 per cent of the state cohort. In rough numbers each year:
- Large states (NSW, VIC, QLD): approximately 500 students per state.
- Smaller states (WA, SA, TAS): approximately 100 students per state.
- ACT: approximately 40 students.
The very highest possible ATAR is 99.95 — and the cohort that achieves it is small (typically only a few dozen students nationwide). The reason it is 99.95 rather than 100 is mathematical: a 99.95 rank means you placed in the top 0.05 per cent. There is no rank above 99.95 because there is no fraction of the cohort smaller than that increment.
What's the highest possible ATAR, and why is it 99.95?
The highest ATAR ever awarded in Australia is 99.95. The rank scale moves in increments of 0.05 percentile points and tops out at 99.95 because nobody can be ranked above the top 0.05 per cent of their cohort.

What is the ATAR?
The ATAR is the Australian Tertiary Admission Rank — a rank between 0.00 and 99.95 that places your overall Year 12 performance in order against your state's eligible Year 12 cohort. An ATAR of 80.00 means you performed better than 80 per cent of the cohort that started Year 12 in your state. The University Admissions Centre (UAC) explains that the rank is designed so universities across Australia can compare students from different schools, subjects and even states on a single fair scale.
Importantly, the ATAR is a rank, not a score. Two students with raw marks of 80 in different subjects can finish on very different ATARs because of scaling — and two students with very different raw mark profiles can finish on the same ATAR. The number you see on results day reflects your relative position in the cohort, not the marks you wrote on each exam.
How is the ATAR calculated?
The ATAR is calculated on a percentile basis, increasing in increments of 0.05. While the exact process varies by state, the four steps are consistent:
- Raw scores. You receive a raw mark for each Year 12 subject from internal assessments and external exams.
- Scaling. Raw scores are scaled to account for the relative strength of the cohort taking each subject — high-scaling subjects like Specialist Mathematics typically see scaled marks rise above the raw, while subjects with weaker cohorts can see scaled marks fall below.

Each state runs its own Year 12 system and tertiary-admissions centre, so the inputs to the ATAR look different even though the output (a 0.00–99.95 rank) is the same:
- New South Wales: Calculated from the Higher School Certificate (HSC). The University Admissions Centre (UAC) handles subject scaling.
- Victoria: Based on Victorian Certificate of Education (VCE) study scores. The Victorian Tertiary Admissions Centre (VTAC) runs the statistical scaling and produces the ATAR.
- Queensland: Calculated by the Queensland Tertiary Admissions Centre (QTAC) from QCE internal assessments and external exams. Queensland transitioned from the Overall Position (OP) to the ATAR in 2020.
- Western Australia: Derived from Western Australian Certificate of Education (WACE) results. The Tertiary Institutions Service Centre (TISC) handles the scaling.
- South Australia & NT: Run by SATAC, using SACE Stage 2 results.
- Tasmania: Run by TASC, using the Tasmanian Certificate of Education.
- ACT: Calculated through the ACT Board of Senior Secondary Studies (BSSS) using a moderated school-based assessment system, then converted to an ATAR.
Although the underlying calculations differ, every ATAR — no matter the state — is treated as equivalent by Australian universities at admissions time.
What is considered a good ATAR?
A "good" ATAR is the rank that gets you into the course you want to study — not a fixed number. For a Year 12 student aiming at a competitive course like medicine, law or actuarial studies at a Group of Eight university, a good ATAR usually sits above 95.00. For a teaching, nursing or business degree at a regional university, a good ATAR might sit between 65.00 and 80.00. And for a TAFE pathway or a course with portfolio-based entry, the ATAR matters far less than the work you submit.
The most useful first step for any Year 12 student is to look up the most recent guaranteed entry ATAR for the courses on their shortlist (each university publishes these), and to add a 2–4 point buffer for adjustment factors.
How important is your ATAR really?
For most undergraduate courses, your ATAR is the single biggest input into whether you receive an offer — but it is not the only one, and it is not permanent. Universities increasingly use adjustment factors (subject-based, location-based, equity-based) that can lift the rank used in selection. Many courses also offer alternative entry pathways: portfolio entry, interview-based selection, bridging diplomas, mature-age entry after a year of TAFE, and inter-institutional transfers after first-year results.
It also fades quickly. By the time you graduate from a Bachelor's degree, almost no employer will ever ask for your ATAR again — your university results, internships and your final degree do the work. Treat the ATAR as the door to the first room of your tertiary education, not as the verdict on your career.
What is the average ATAR?
The median ATAR awarded each year sits around 70.00. This number is higher than it intuitively feels, because the ATAR is calculated against the full eligible Year 12 cohort in each state — not only against the students who actually finish Year 12 with an ATAR. Students who leave school early, take vocational pathways, or don't complete enough scoring subjects are still counted in the denominator.
So an ATAR of 70.00 places a student in the top 30 per cent of the eligible cohort, but only roughly the top 50 per cent of students who actually receive an ATAR on results day. This is also why the median ATAR is around 70 rather than 50 — about a third of the cohort doesn't end up with an ATAR at all.
Is it hard to get an ATAR above 85?
An ATAR of 85.00 places you in the top 15 per cent of the state cohort, or roughly the top 25 per cent of students who actually receive an ATAR. It is genuinely an impressive rank — but it is achievable for any motivated student with consistent study habits, well-chosen subjects, and structured exam preparation across the Year 12 year. For practical strategies, our guide on how to achieve your dream ATAR walks through what 85+ students typically do differently from 65–75 students.
How many students achieve an ATAR of 99 or above?
Students with an ATAR of 99.00 or above sit in the top 1 per cent of the state cohort. In rough numbers each year:
- Large states (NSW, VIC, QLD): approximately 500 students per state.
- Smaller states (WA, SA, TAS): approximately 100 students per state.
- ACT: approximately 40 students.
The very highest possible ATAR is 99.95 — and the cohort that achieves it is small (typically only a few dozen students nationwide). The reason it is 99.95 rather than 100 is mathematical: a 99.95 rank means you placed in the top 0.05 per cent. There is no rank above 99.95 because there is no fraction of the cohort smaller than that increment.
What's the highest possible ATAR, and why is it 99.95?
The highest ATAR ever awarded in Australia is 99.95. The rank scale moves in increments of 0.05 percentile points and tops out at 99.95 because nobody can be ranked above the top 0.05 per cent of their cohort. The minimum reported ATAR is 30.00 — students whose aggregate would produce a rank below 30.00 simply receive a "less than 30.00" notation rather than a specific number.
Every year, a few hundred students nationwide score 99.95. They aren't necessarily the students with the highest raw marks in every subject — they are the students whose aggregate across their best subjects, after scaling, sits in the very top sliver of the curve. This is why students aiming for the highest ranks often choose a subject mix that combines a high-scaling subject (like Specialist Mathematics or a language) with subjects they can comfortably top.
Do Year 11 subjects count towards your ATAR?
For most students in most states, the answer is no — the ATAR is calculated almost entirely from Year 12 results. The two practical exceptions are: (1) Year 11 students who accelerate a Year 12 unit (for example, completing VCE Unit 3/4 in Year 11) and have that result counted in their final aggregate, and (2) some Queensland and ACT students whose moderated Year 11 internal assessments feed into the system.
That said, Year 11 isn't wasted. The content you cover in Year 11 is treated as assumed knowledge in Year 12, and a strong Year 11 builds the study habits, the subject confidence, and the assessment technique that determines how well you handle Year 12 internals and exams.
Is the ATAR rank equivalent across states?
Yes. Although each state calculates the ATAR through its own tertiary-admissions centre, every Australian university treats every ATAR as equivalent for admissions purposes. A 95.00 from Western Australia, a 95.00 from Queensland, and a 95.00 from New South Wales all sit at the same point in the rank order and qualify for the same selection rank at any university in the country.
Students completing other senior-secondary qualifications — like the International Baccalaureate (IB) Diploma — receive a "notional ATAR" through a published conversion table maintained by UAC, and this notional rank is treated identically to a state-issued ATAR.
What's the difference between ATAR, ENTER and OP?
You'll still see the older terms in Year 12 conversation. Here's the simple translation:
- ATAR: The current national rank, used in every state since Queensland transitioned in 2020. Range: 0.00–99.95.
- ENTER: The "Equivalent National Tertiary Entrance Rank" used in Victoria until 2009. The ATAR replaced the ENTER from the 2010 cohort onwards.
- OP (Overall Position): Queensland's pre-2020 system. OPs ran on a 1–25 scale (with OP 1 being the highest band). Queensland Year 12 students from 2020 onwards receive ATARs through QTAC instead.
If a parent or older sibling refers to "their ENTER" or "their OP", they're describing the same concept — a rank used to enter university — under an earlier name. Universities still recognise these older ranks for mature-age applications.
How can I get a high ATAR?
There is no single fact that lifts an ATAR — it is the product of consistent work across the Year 12 year. Students who finish in the top 15 per cent typically do these things:
- Choose subjects strategically. Pick subjects that align with your strengths and your university course prerequisites. A high-scaling subject can lift your aggregate, but only if you can sit comfortably in its top half — high-scaling subjects don't help if you finish in the bottom of the cohort.
- Stay consistent across the year. The students who score above 90 are almost never the students who started studying in October. They're the ones who maintained 1–2 hours of focused study every weeknight from Term 1.
- Practice past papers earlier than feels comfortable. Doing past papers under timed conditions from the start of Term 3 (rather than Term 4) reliably lifts exam marks by training pacing and question recognition.
- Master exam technique alongside content. Knowing the subject is necessary but not sufficient — students lose ranks to slow handwriting, misreading marking schemes, and poor essay structure rather than poor content recall.
- Get help on the topics you avoid. Working with a Year 12 specialist tutor on the topics you privately know are weakest is one of the highest-leverage uses of study time. Tutoring with a senior-school subject specialist starts from A$65/hr with Tutero, with no contracts.

Frequently asked questions about the ATAR
Is the ATAR a percentage or a rank?
It's a rank, not a percentage. An ATAR of 80.00 doesn't mean you scored 80 per cent on anything — it means you performed better than 80 per cent of your state's eligible Year 12 cohort.
Do all Australian states use the ATAR?
Yes — every state and the ACT now uses the ATAR. Queensland was the last to transition, replacing the OP with the ATAR for the 2020 Year 12 cohort onwards.
What does ATAR stand for?
Australian Tertiary Admission Rank.
What's the lowest ATAR you can receive?
The lowest reported ATAR is 30.00. Students whose aggregate would produce a rank below 30.00 receive a "less than 30.00" notation instead.
The ATAR is a starting line, not a final score
The ATAR gives Australian universities one fair, comparable measure of school-leaver performance — and that's a useful thing for selection. But it does not define a student's potential, lock in a single career path, or close other doors. Bridging diplomas, portfolio courses, vocational pathways, and mature-age entry all lead to the same university degrees and the same careers. Understanding how the ATAR is calculated, what counts as "good" for the courses on your shortlist, and how to plan strategically across Year 12 is what turns the rank from an anxiety into a tool. Every Year 12 student deserves that clarity — and a study plan that earns the rank they're aiming for.
