How Is An Atar Calculated

Estimate your Australian Tertiary Admission Rank (ATAR) based on your subject scores and scaling factors.

How is an ATAR Calculated? The Complete 2024 Guide

The Australian Tertiary Admission Rank (ATAR) is the primary metric used by universities to rank and select school leavers for undergraduate courses. Understanding how your ATAR is calculated can help you make informed decisions about your subject selection and study strategies.

1. The ATAR Fundamentals

The ATAR is a percentile rank between 0.00 and 99.95 that indicates your overall academic performance relative to other students in your age group. It is not a mark out of 100 – an ATAR of 80.00 means you performed better than 80% of your year group, not that you scored 80%.

2. The ATAR Calculation Process

The calculation involves several key steps:

1. Raw Subject Scores: Your performance in each subject is first assessed and given a raw score (typically out of 100).
2. Scaling: Raw scores are adjusted through a statistical process called “scaling” to account for differences in subject difficulty and student cohorts.
3. Aggregation: Your best scaled scores are combined to produce an aggregate score.
4. Ranking: Your aggregate is compared to all other students to determine your percentile rank (ATAR).

3. Subject Scaling Explained

Scaling is the most complex and often misunderstood part of ATAR calculation. Each state has its own scaling system:

State	Scaling System	Key Features
NSW	HSC Scaling	Uses performance bands and cohort comparisons. Mathematics Extension 2 typically scales highest.
VIC	VCE Scaling	Uses study scores (max 50) which are scaled based on subject difficulty. Specialist Mathematics scales highest.
QLD	QCE Scaling	Uses a different system where subject results are converted to a common scale before aggregation.
WA	WACE Scaling	Similar to NSW but with different weightings for different subject levels.

For example, in Victoria, a raw study score of 40 in Specialist Mathematics might scale to about 50, while the same raw score in a less competitive subject might scale to 35.

4. The Aggregation Process

Your final ATAR is calculated from your best:

• NSW/VIC/WA/SA/ACT: Best 4 scaled subjects (plus 10% of a 5th subject in some states)
• QLD: Best 5 general subjects (or 4 general + 1 applied)
• NT: Best 4 Stage 2 subjects

English (or equivalent) is typically compulsory and must be included in your best subjects.

5. Common Misconceptions About ATAR

Many students have incorrect beliefs about how ATAR works:

• Myth 1: “You need to get 99% in all subjects to get a 99 ATAR” – False. Scaling means you can achieve a high ATAR without perfect scores in all subjects.
• Myth 2: “Some subjects are worth more points” – False. All subjects contribute equally to your aggregate after scaling.
• Myth 3: “The ATAR is calculated from your raw scores” – False. Raw scores are always scaled before aggregation.
• Myth 4: “You can calculate your exact ATAR” – False. The exact calculation requires data from the entire student cohort, which isn’t available until after exams.

6. How Universities Use Your ATAR

Universities use ATAR in different ways:

University Group	Typical ATAR Use	Additional Considerations
Group of Eight (Go8)	Primary selection criterion	Often have high ATAR cutoffs (80-99 depending on course)
Regional Universities	One of several criteria	More flexible entry paths, often consider other factors
Private Colleges	Sometimes not required	May use alternative entry assessments
TAFE	Rarely required	Focus on specific course prerequisites

Many universities also use:

• Bonus points for specific subjects
• Adjustment factors for disadvantaged students
• Portfolios or interviews for creative courses
• Special entry schemes for rural/indigenous students

7. Strategies to Maximize Your ATAR

While you can’t control the scaling process, you can optimize your approach:

1. Choose subjects you enjoy and are good at – You’ll perform better in subjects that interest you.
2. Balance your subject selection – Include at least one subject that scales well in your state.
3. Focus on consistent performance – ATAR rewards consistent high performance across all subjects.
4. Understand assessment requirements – Know exactly what examiners are looking for in each subject.
5. Prepare for exams strategically – Past papers are the best preparation for final exams.
6. Consider acceleration – Some students benefit from doing Year 12 subjects in Year 11.

8. ATAR Alternatives and Pathways

If your ATAR isn’t what you hoped for, there are many alternative pathways:

• Diploma pathways – Complete a diploma that articulates into a degree
• Foundation programs – Preparatory courses that guarantee entry
• TAFE to university – Many degrees offer credit for TAFE qualifications
• Special entry schemes – For disadvantaged or special circumstances
• Portfolio entry – For creative courses based on your work samples
• Mature age entry – After a gap year or work experience

9. ATAR Trends and Statistics

The ATAR landscape changes slightly each year. Recent trends include:

• Increasing competition – More students achieving high ATARs each year
• Subject popularity shifts – STEM subjects becoming more popular
• Alternative entry growth – More students using non-ATAR pathways
• Early offers increasing – More universities making early conditional offers

In 2023, the median ATAR was approximately 70.00, with about:

• 15% of students achieving 90.00+
• 35% achieving 80.00-89.95
• 30% achieving 70.00-79.95
• 20% achieving below 70.00

10. Common Questions About ATAR

Q: Can I calculate my exact ATAR before results are released?

A: No, because the scaling process depends on how all students in your state performed, which isn’t known until after exams are marked. Our calculator provides an estimate based on historical scaling data.

Q: Do universities only look at ATAR?

A: While ATAR is the primary criterion for most courses, universities also consider other factors like:

• Subject prerequisites
• Bonus points for specific subjects
• SEAS/educational disadvantage adjustments
• Portfolios for creative courses
• Interviews or auditions for some programs

Q: How accurate are ATAR estimators?

A: Estimators can give you a reasonable approximation (typically within ±5 ATAR points) but cannot predict your exact ATAR due to the complex scaling process and yearly variations in student performance.

Q: Does the ATAR expire?

A: No, your ATAR doesn’t expire, but some universities may have policies about how recently you completed Year 12 when considering your application.

Q: Can I improve my ATAR after Year 12?

A: You cannot change your ATAR after it’s been calculated, but you can:

• Repeat Year 12 (your new ATAR will replace the old one)
• Complete additional studies (some states allow this)
• Use alternative entry pathways

11. The Future of ATAR

The ATAR system is periodically reviewed, with ongoing discussions about:

• Alternative assessment methods – Moving beyond final exams
• More holistic admissions – Considering a wider range of student attributes
• National consistency – Potentially standardizing systems across states
• Digital assessment – Using technology for more sophisticated marking

Some universities are already moving toward more comprehensive admissions processes that consider:

• Co-curricular achievements
• Work experience
• Personal statements
• Online interviews
• Psychometric testing

12. Final Advice for Students

While the ATAR is important, remember:

1. It’s just one number that doesn’t define your intelligence or potential
2. There are always alternative pathways to your goals
3. Universities care about more than just your ATAR
4. Many successful people didn’t get the ATAR they wanted
5. Your attitude and work ethic matter more in the long run

Focus on doing your best in subjects you enjoy, and the ATAR will take care of itself. If things don’t go as planned, there are always other options to reach your goals.
