The ATAR, explained for parents

The ATAR is a rank, not a mark. It tells you where your child sits relative to their age group, not how many questions they got right. Here is what it means, how scaling works, and why a lower number is rarely the end of the road.

Last updated 2026-07-03.

The ATAR is a rank, not a mark. It is a number between 0 and 99.95 that tells you where your child sits compared with everyone else their age, not how many questions they got right. An ATAR of 85.00 means a student performed better than about 85 percent of their age group. It is a tool universities use to sort applicants for competitive courses, and it is only one of several ways in.

If you take one thing from this page: your child's ATAR is a position in a line, not a grade on a report. Understanding that changes almost every conversation you will have about subjects, results and university.

Key fact

ATAR = Australian Tertiary Admission Rank. It runs from 0 to 99.95 in steps of 0.05. The highest reported rank is 99.95. It measures relative position in an age group, not a percentage score and not a measure of ability.

What is the ATAR, really?

Think of every student in your child's age group lined up from strongest to weakest academic performance for that year. The ATAR tells you roughly how far along that line your child stands. A 90.00 means about 10 percent of the age group did better; a 70.00 means about 30 percent did.

Two things make this different from a normal mark:

It is relative. Your child is measured against other students, not against a fixed pass line. If everyone improves, the ranks do not all rise together, because someone still has to be at each position.
It covers the whole age group, including students who left school early or did not sit exams, not just the students who finished Year 12. This is why the admissions centre in your state, not the school, calculates it.

Each state runs this through its own tertiary admissions centre: UAC in NSW and the ACT, VTAC in Victoria, QTAC in Queensland, SATAC in South Australia and the NT, TISC in Western Australia, and the University of Tasmania in Tasmania. The ATAR itself is national and means the same thing across the country.

How does ATAR scaling work, and why does it matter?

Scaling is the part that confuses almost everyone, so here is the plain version. Because students take different combinations of subjects, the marks from different subjects cannot simply be added together as they are. A raw mark of 80 in one subject is not necessarily the same achievement as an 80 in another. To make them comparable, the admissions centre scales each subject every year.

The key idea most families get wrong: scaling is about the strength of the group taking a subject, not about whether a subject is "hard". A subject tends to scale up when the students taking it also tend to do well across all their other subjects. It scales down when, on average, the group performs less strongly elsewhere. It is a comparison between cohorts, not a reward for difficulty.

What scaling really compares

Scaling asks: how did the students in this subject perform in their other subjects? If a subject is full of high achievers, a strong mark in it is treated as a strong achievement, so marks tend to scale up. It is the competition, not the syllabus, that moves the numbers.

Two consequences worth knowing:

Scaling is recalculated every year. Last year's pattern is a guide, never a promise. No tutor, teacher or website can tell you a subject's exact future scaling.
Chasing scaling by picking a subject your child dislikes or struggles with usually backfires. A modest mark in a "well-scaling" subject often ends up worse than a strong mark in a subject they enjoy and work hard at. We unpack this in how ATAR scaling works and in our subject-selection guide.

What counts as a "good" ATAR?

A good ATAR is the one that gets your child into a course they actually want. That is the whole answer. It is not 90, it is not 95, and it is not whatever a neighbour's child got.

Families routinely aim far higher than they need to. Many well-regarded degrees, including teaching, nursing, business, IT, the arts and plenty of science courses, have entry ranks well below the numbers people assume. Some courses select on more than the ATAR: interviews, portfolios, auditions, or aptitude tests. And most universities apply adjustment factors that lift a student's selection rank above their raw ATAR.

We deliberately do not quote specific cut-offs here, because they change every year and vary by university and campus. Instead, look them up properly:

Search the specific courses on your state admissions centre (UAC, VTAC, QTAC, SATAC, TISC or the University of Tasmania).
Check each university's own course pages for guaranteed entry ranks.
Compare courses side by side on our university finder.

For a deeper look at reframing this question, see what is a good ATAR.

Selection rank versus ATAR: what is the difference?

The ATAR is the raw rank. The selection rank is what a university actually uses to make an offer, and it can be higher than the ATAR once adjustment factors are added. Adjustment factors (sometimes called bonus points or access schemes) can be awarded for things like:

studying particular subjects relevant to the course,
financial or personal hardship,
attending a school in an under-represented area,
living in a regional or remote location,
elite sport, or other equity considerations.

So a student with an ATAR of 78 might reach a selection rank of 83 or more for a particular course. This is why the raw number on results day is not the final word. Each university publishes its own adjustment schemes.

Is the ATAR the only way into university?

No, and this matters. The ATAR is the most visible route, not the only one. Real alternatives include:

Early entry and guaranteed entry schemes, where universities make offers based on Year 11 and 12 results, a principal's recommendation or an application, sometimes before final exams.
Diploma and enabling or foundation courses that lead into a degree.
TAFE and vocational pathways that articulate into university with credit.
Portfolio, audition and interview-based entry for creative and some professional courses.
Starting a related degree and transferring once at university, using first-year results.

Our pathways guide walks through these routes for the moment when plan A does not land, and the university finder lets you see entry options for real courses.

Your state's ATAR explained

The ATAR means the same thing everywhere, but each state builds it from its own certificate and rules. For the detail on how your child's results become an ATAR, including eligibility, scaling and the aggregate, see the explainer for your state:

NSW HSC: how the HSC ATAR is calculated
VIC VCE: how the VCE ATAR is calculated
QLD QCE: how the QCE ATAR is calculated
SA SACE: how the SACE ATAR is calculated
WA WACE: how the WACE ATAR is calculated
TAS TCE: how the TCE ATAR is calculated

Try a calculator together

If your child wants to see how their marks might translate into a rank, an ATAR calculator is a low-stakes way to explore it as a family. It is an estimate, not a prediction, but it makes scaling and subject choice concrete:

NSW HSC: HSC ATAR calculator
Victoria VCE: VCE ATAR calculator
Queensland QCE: QCE ATAR calculator

A calm way to use these

Treat the number as a conversation starter, not a verdict. The point is to see how different subjects and effort levels move the estimate, not to lock in an expectation your child then feels they must hit.

How can I help as a parent?

Learn the vocabulary once. Knowing that the ATAR is a rank, that scaling compares cohorts, and that selection rank can beat the raw ATAR lets you have calmer, better conversations.
Aim at courses, not numbers. Help your child research the actual entry requirements for courses they care about, using the official sources above.
Keep the ATAR in proportion. It is one year, one set of subjects, one narrow measure. It does not define your child, and for many students it is not even the route they end up taking.

Frequently asked questions

Is the ATAR a mark or a score?

Neither. The ATAR is a rank between 0 and 99.95, reported in steps of 0.05. It tells you the percentage of the age group a student outperformed. An ATAR of 80.00 means the student is ranked in roughly the top 20 percent of their age group, not that they scored 80 percent in an exam. Because it is a rank of the whole age group and not just those who sat exams, the numbers are calculated by the state tertiary admissions centre, such as UAC, VTAC or QTAC.

What is a good ATAR?

A good ATAR is simply one that gets your child into a course they want to do. That is different for every course. Many respected university degrees have entry ranks well below the numbers families assume, and selection rank (which can include adjustment factors) often matters more than the raw ATAR. The honest answer is to look up the actual entry requirement for the specific courses your child is considering rather than aiming at a round number like 90.

Does a higher ATAR mean my child is smarter?

No. The ATAR measures relative academic performance across a set of subjects in one year, against one age group. It says nothing about intelligence, character, work ethic or how well someone will do in their career or their chosen field. It is a sorting tool for university entry, and a narrow one.

How is scaling worked out and can we predict it?

Scaling is done each year by the tertiary admissions centre based on how the whole group of students taking each subject performs across all their subjects. It is recalculated every year, so last year's scaling is a guide, not a guarantee, and no one can tell you a subject's exact scaling in advance. This is why choosing a subject purely to chase scaling is risky.

What if my child's ATAR is lower than they hoped?

A lower ATAR closes fewer doors than most families fear. Adjustment factors, early entry schemes, diploma and pathway courses, TAFE-to-university transfers, and starting a related degree then switching are all real routes. Universities have whole teams devoted to alternative entry. Our pathways guide walks through the options calmly.

Where do I find real ATAR cut-offs?

Use the official course search on your state admissions centre (UAC for NSW and ACT, VTAC for Victoria, QTAC for Queensland, SATAC for South Australia and the NT, TISC for WA, UTAS for Tasmania) and each university's own course pages. These show the guaranteed or previous-year entry ranks. You can also compare courses on our university finder.
