Understanding ATAR: A Complete Guide for Australian Parents

The Australian Tertiary Admission Rank (ATAR) is a percentile ranking from 0 to 99.95 that indicates a student's overall academic achievement relative to all Year 12 students in their state. Approximately 60,000 students in NSW and 50,000 in Victoria receive an ATAR each year. An ATAR of 90.00 means the student performed better than 90% of their Year 12 cohort. In 2025, the median ATAR across Australia was approximately 70.00, while entry to competitive university courses like Medicine typically requires an ATAR above 99.00.

This guide breaks down how the ATAR is calculated, what it means in practice, how universities use it, and what parents should understand to support their children through Year 11 and 12. School performance data is drawn from AU Guide's analysis of 2025 HSC and VCE results across 800+ NSW schools and 530+ VIC schools.

Overview: What Is the ATAR?

The ATAR is not a score or a mark — it is a rank. Specifically, it is a percentile rank that compares a student's overall Year 12 performance against all students in their state who were eligible for an ATAR in that year. Key facts:

• The ATAR scale runs from 0 to 99.95, in increments of 0.05
• An ATAR of 80.00 means the student outperformed 80% of their Year 12 cohort
• It is calculated from the student's best subjects (not all subjects)
• It is used primarily for university admissions
• Not every Year 12 student receives an ATAR — students who do not complete enough eligible subjects or who choose vocational pathways may not receive one

The ATAR replaced the older UAI (Universities Admission Index) in NSW and the Equivalent National Tertiary Entrance Rank (ENTER) in Victoria. It was introduced nationally in 2009–2010 to standardise university admission rankings across states.

How the ATAR Is Calculated

NSW (HSC)

In NSW, the ATAR is derived from the Higher School Certificate (HSC) results. The calculation process is:

1. Each HSC subject receives a raw exam mark and a moderated assessment mark
2. These are combined into an HSC mark (reported on the student's results notice)
3. HSC marks are then scaled by the Universities Admissions Centre (UAC) to account for the difficulty of each subject and the calibre of students taking it
4. The student's best 10 units of scaled marks are aggregated (an "aggregate")
5. This aggregate is converted to a percentile rank — the ATAR

The "best 10 units" rule means a student typically needs at least 5 HSC subjects (most subjects are worth 2 units). English is compulsory and must be included. The remaining 8 units come from the student's next best subjects.

Victoria (VCE)

In Victoria, the ATAR is derived from the Victorian Certificate of Education (VCE) results. The process is similar:

1. Each VCE subject receives a study score (0–50 scale, with 30 being the mean)
2. Study scores are scaled by VTAC to account for subject difficulty
3. The student's primary four subjects (including English) plus 10% of the next two best scaled scores form the aggregate
4. This aggregate is converted to a percentile rank — the ATAR

In Victoria, the calculation uses a "primary four plus increments" approach rather than NSW's "best 10 units" method. English (or an approved English equivalent) must be one of the primary four subjects.

Scaling: Why Subject Choice Matters

Scaling is the most commonly misunderstood aspect of the ATAR. Here is what parents need to know:

Important: scaling adjusts for the academic strength of the cohort taking a subject, not the perceived difficulty of the content. A student should choose subjects they enjoy and will perform well in, not simply the subjects that scale highest. A high raw mark in a lower-scaling subject often produces a better ATAR contribution than a mediocre mark in a higher-scaling subject.

ATAR and University Admissions

How Universities Use the ATAR

Most Australian universities use the ATAR as the primary criterion for undergraduate admissions. Each course has a published "cutoff" ATAR — the minimum rank required for an offer in a given year. These cutoffs change annually based on demand and available places.

Beyond the ATAR

While the ATAR is important, it is not the only pathway to university. Alternatives include:

• Adjustment factors — many universities add bonus points for factors like geographic location, financial disadvantage, or subject relevance (e.g., completing HSC Chemistry for a science degree)
• Portfolio or interview entry — some courses in creative arts, music, and design consider portfolios alongside or instead of the ATAR
• Special consideration — students who experienced illness, hardship, or disruption during Year 12 can apply for special consideration
• Pathway programs — foundation studies, diplomas, and TAFE qualifications can lead to university entry without an ATAR
• Mature age entry — students over 21 can often enter university based on work experience or prior study without an ATAR

ATAR by State: Key Differences

Despite these differences, the ATAR itself is designed to be comparable across states. An ATAR of 90.00 in NSW is intended to represent the same level of achievement as an ATAR of 90.00 in Victoria or Queensland. Cross-state university applications use the ATAR directly without conversion.

How Schools Influence ATAR Outcomes

While the ATAR is an individual student's rank, the school a student attends can significantly influence their results. Schools differ in:

• Subject availability — some schools offer more scaling-friendly subjects or specialist courses
• Teaching quality — experienced teachers in key subjects can make a substantial difference
• Peer effect — students at academically selective or high-performing schools benefit from a motivated peer group
• Assessment quality — internal assessments are moderated against external exams, so schools with rigorous internal programs better prepare students

In NSW, James Ruse Agricultural High School (AU Guide Score: 97.75, 705 Distinguished Achievers in 2025 HSC) consistently produces the highest concentration of top-ATAR students. In Victoria, MacRobertson Girls High School (AU Guide Score: 99.30, median VCE study score: 37) leads the state rankings. Parents can compare school performance using the AU Guide NSW School Rankings and AU Guide VIC School Rankings.

What This Means for Families

For Primary School Parents

The ATAR is years away, but school choice in Year 7 can influence Year 12 outcomes. If your child is academically inclined, consider selective schools (free, government-run, competitive entry) or high-performing comprehensive schools. Research school HSC/VCE results using AU Guide's school rankings to understand which schools consistently produce strong ATAR outcomes.

For Year 9–10 Parents

Subject selection in Year 10 (for Year 11–12) is the most important ATAR-related decision your family will make. Key principles:

• Choose subjects your child is genuinely interested in and performs well in — a high mark in any subject is better than a mediocre mark in a "good scaling" subject
• Ensure at least 12 units are selected (10 will count, giving a 2-unit buffer)
• Include prerequisite subjects for intended university courses (check university handbooks)
• English is compulsory for the ATAR — invest in strong English performance

For Year 11–12 Parents

During the ATAR years, parents can help by:

• Understanding that assessment marks and exam marks are both important — internal assessments typically count for 50% of the HSC mark
• Supporting consistent study habits rather than last-minute cramming
• Being aware that one bad exam does not destroy an ATAR — the "best 10 units" rule provides a buffer
• Encouraging balance — wellbeing and rest are essential for sustained academic performance

FAQ

What ATAR do you need to get into university?

It depends on the course and university. Broadly, an ATAR of 70+ opens the door to many bachelor degrees at most universities. Competitive courses at top universities typically require 90+, while Medicine and Law at leading institutions may require 99+. In 2025, most regional universities accept students with ATARs of 60–70 for generalist degrees. Many universities also offer adjustment factors that can add 1–10 points to a student's ATAR for admissions purposes.

Is the ATAR calculated the same way in every state?

No. Each state has its own Year 12 certificate (HSC in NSW, VCE in Victoria, QCE in Queensland) and its own calculation method. In NSW, the best 10 units of scaled HSC marks are used. In Victoria, the primary 4 subjects plus 10% of the next 2 best scaled scores are aggregated. However, the final ATAR is designed to be comparable across states — an ATAR of 85.00 in NSW represents the same percentile position as 85.00 in Victoria.

Does subject choice affect the ATAR?

Yes, through scaling. Subjects taken by higher-performing cohorts tend to scale up, meaning a given raw mark converts to a higher contribution to the ATAR aggregate. However, the most important factor is performing well in your chosen subjects. A raw mark of 95 in a lower-scaling subject typically contributes more to the ATAR than a raw mark of 75 in a higher-scaling subject. Choose subjects based on genuine interest and ability.

Can you get into university without an ATAR?

Yes. Universities offer multiple alternative pathways including: TAFE diplomas (which can articulate into the second year of a degree), foundation programs, portfolio-based entry for creative courses, mature age entry (over 21), and special admission schemes. The ATAR is the most common pathway but it is not the only one. Approximately 30–40% of university entrants nationally are admitted through pathways other than the ATAR.

What is a "good" ATAR?

An ATAR of 80.00 means the student performed better than 80% of their Year 12 cohort — this is a strong result that opens doors to most university courses at most institutions. An ATAR of 90.00 or above places the student in the top 10%, and 95.00 or above in the top 5%. What constitutes a "good" ATAR depends on the student's goals: a student aiming for primary teaching (typically ATAR 70–80) needs a different target than one aiming for Medicine (typically 99+).

How do schools affect ATAR results?

School choice influences ATAR outcomes through teaching quality, subject availability, peer motivation, and assessment rigour. High-performing schools like James Ruse Agricultural High School (AU Guide Score: 97.75) and MacRobertson Girls High School (AU Guide Score: 99.30) consistently produce high-ATAR students. However, individual effort remains the most important factor — motivated students at comprehensive schools regularly achieve ATARs above 95.
