ATAR Score Calculator - Australia 2025
What is ATAR? The Australian Tertiary Admission Rank (ATAR) is a number between 0 and 99.95 that indicates your position relative to other students in your age cohort. An ATAR of 80.00 means you performed better than 80% of students in your age group.
VCE ATAR Calculator (Victoria)
VCE Aggregate Formula:
\[ \text{Aggregate} = \text{English Score} + \text{Top 3 Scaled Scores} + 0.10 \times (\text{5th Score} + \text{6th Score}) \]
How VCE ATAR is Calculated: Your ATAR is based on an aggregate of your scaled study scores. The aggregate includes 100% of your English score, 100% of your top 3 subject scores, and 10% of your 5th and 6th subject scores.
HSC ATAR Calculator (NSW)
HSC Aggregate Formula:
\[ \text{Aggregate} = \text{Best 2 Units of English} + \text{Best 8 Units from Remaining Subjects} \]
How HSC ATAR is Calculated: Your ATAR is based on an aggregate of scaled marks in 10 units. This includes your best 2 units of English (mandatory) plus the best 8 units from your remaining subjects. Subjects are scaled based on the performance of students across all their courses.
QCE ATAR Calculator (Queensland)
QCE Aggregate Formula:
\[ \text{Aggregate} = \sum_{i=1}^{5} \text{Scaled Subject Score}_i \]
How QCE ATAR is Calculated: Your ATAR is calculated from your best five General subjects. Each subject is scaled based on the cohort's performance. The scaled scores are summed to create an aggregate, which is then converted to an ATAR.
WACE ATAR Calculator (Western Australia)
WACE Aggregate Formula:
\[ \text{Aggregate} = \text{Best 4 Scaled Scores} + 0.10 \times \text{LOTE Score (if applicable)} \]
How WACE ATAR is Calculated: Your ATAR is based on your best four scaled scores. If you study a Language Other Than English (LOTE), 10% of your LOTE scaled score is added to your aggregate.
SACE ATAR Calculator (South Australia)
SACE Aggregate Formula:
\[ \text{University Aggregate} = \sum \text{Scaled Subject Scores} \]
How SACE ATAR is Calculated: Your ATAR is based on a university aggregate calculated from your best subjects. Each subject is scaled and the scaled scores are summed. The aggregate is then converted to an ATAR using the SATAC conversion table.
IB to ATAR Conversion Calculator
IB Score Calculation:
\[ \text{IB Score} = \sum_{i=1}^{6} \text{Subject Score}_i + \text{TOK/EE Points (max 3)} \]
Maximum IB Score: \( 45 \) points
How IB Converts to ATAR: IB students receive an IB Admissions Score (IBAS) which is converted to an equivalent ATAR for Australian university applications. The conversion ensures fair comparison between IB and ATAR students.

Understanding ATAR Scaling
What is Scaling? Scaling is the process of adjusting raw scores to account for the difficulty of subjects and the academic strength of each subject cohort. This ensures students are neither advantaged nor disadvantaged by their choice of subjects.
Scaling Principle:
\[ \text{Scaled Score} = f(\text{Raw Score}, \text{Cohort Performance}, \text{Subject Difficulty}) \]
Important: High-scaling subjects (like Specialist Mathematics, Physics) typically have academically strong cohorts. However, performing poorly in a high-scaling subject can still result in a low aggregate score. Choose subjects you excel in and enjoy!
State-by-State ATAR Calculation Methods
| State | Curriculum | Tertiary Admissions Center | Calculation Method |
|---|---|---|---|
| Victoria | VCE | VTAC | Aggregate from top 4 subjects + 10% of 5th & 6th |
| New South Wales | HSC | UAC | Best 2 units of English + best 8 units |
| Queensland | QCE | QTAC | Best 5 General subjects scaled |
| Western Australia | WACE | TISC | Best 4 scaled scores + 10% LOTE bonus |
| South Australia | SACE | SATAC | University aggregate from scaled subjects |
ATAR Percentiles Explained
An ATAR is a percentile rank, not a mark out of 100. It shows your position relative to all students in your age cohort (typically 16-20 year olds).
| ATAR | Percentile Meaning | Approximate Students |
|---|---|---|
| 99.95 | Top 0.05% of students | ~147 students nationally |
| 99.00 | Top 1% of students | ~1,600 students |
| 95.00 | Top 5% of students | ~8,000 students |
| 90.00 | Top 10% of students | ~16,000 students |
| 80.00 | Top 20% of students | ~32,000 students |
| 70.00 | Top 30% of students | ~48,000 students |
| 50.00 | Median (top 50%) | ~80,000 students |
VCE Study Score to Scaled Score
In VCE, study scores range from 0-50 with an average of 30. These are then scaled by VTAC based on the performance of students in that subject across all their other subjects.
Example VCE Scaling:
Raw Study Score: \( 40 \) in Specialist Mathematics
Scaled Study Score: \( \approx 47 \) (scaled up due to strong cohort)
Common ATAR Requirements for University Courses
| Course Type | Typical ATAR Requirement | Examples |
|---|---|---|
| Medicine | 99.00 - 99.95 | MBBS, Doctor of Medicine |
| Dentistry | 95.00 - 98.00 | Bachelor of Dental Science |
| Law | 95.00 - 99.50 | Bachelor of Laws (LLB) |
| Engineering | 85.00 - 95.00 | Bachelor of Engineering (Honours) |

ATAR Adjustment Factors
What are Adjustment Factors? Many universities offer ATAR adjustment factors (bonus points) based on:
- Subject Performance: Bonus points for excellent performance in relevant subjects (e.g., STEM subjects for Engineering)
- Educational Access Schemes (EAS): Additional points for students facing disadvantage
- Regional/Rural Location: Extra points for students from regional areas
- Elite Athlete/Performer Scheme: Adjustments for high-achieving athletes or performers
- Equity Schemes (SEAS, ACCESS): Support for students with special circumstances

ATAR Prediction Tips
For Accurate ATAR Predictions:
- Use multiple ATAR calculators (VTAC, UAC, Matrix, Deakin, ATAR Notes)
- Account for scaling effects on your subjects
- Be realistic with your estimated scores
- Consider your SAC/assessment performance throughout the year
- Check previous years' scaling reports for your subjects
- Remember: calculators provide estimates, not guarantees
Frequently Asked Questions
Q: Can I calculate my ATAR with SAC scores?
A: SAC scores contribute 50% to your study score. You'll need to estimate your exam performance to predict your final study score, then use that to calculate your ATAR.
Q: Which ATAR calculator is most accurate?
A: Official calculators from VTAC, UAC, QTAC, and TISC are most accurate for their respective states. Third-party calculators from Deakin, ATAR Notes, and Matrix Education use official scaling data and are generally reliable.
Q: How does ATAR scaling work?
A: Scaling adjusts raw scores based on the academic strength of students taking each subject. Subjects with stronger cohorts (who perform well across all subjects) scale up more than subjects with weaker cohorts.
Q: Can I improve my ATAR?
A: Yes! You can retake subjects, complete additional subjects, or apply for adjustment factors through equity schemes. Some universities also offer alternative pathways.
