📚 What is ATAR?
The Australian Tertiary Admission Rank (ATAR) is a percentile ranking between 0.00 and 99.95 that indicates a student's position relative to all students in their age cohort[web:14][web:17]. An ATAR of 90.00 means the student performed better than 90% of the cohort.
ATAR Calculation Formula
ATAR = f(Scaled Subject Aggregate)
Where aggregate is sum of best scaled subject scores
ATAR is calculated differently in each Australian state but all produce the same 0.00-99.95 scale in increments of 0.05[web:14][web:17].
🔢 How ATAR is Calculated by State
General Calculation Process:
- Raw Scores: Students receive raw scores for each subject based on assessment performance[web:14]
- Scaling: Raw scores are scaled to account for difficulty differences between subjects[web:17]
- Aggregate: Best scaled subject scores are added to create an aggregate (varies by state)[web:14][web:17]
- Ranking: Students are ranked in descending order by aggregate score[web:14]
- ATAR Assignment: Rankings are converted to percentiles on the 0.00-99.95 scale[web:17]
State-Specific Methods:
NSW/ACT (HSC):
Based on aggregate of scaled marks in 10 units: best 2 units of English + best 8 units from remaining subjects[web:17].
Victoria (VCE):
Aggregate of scaled study scores: English/EAL + best 3 subjects (Primary Four) counted fully + 5th and 6th subjects count 10% each[web:16]. Maximum aggregate approximately 210.
Queensland (QCE):
Based on best five scaled subject results from General subjects, Applied subjects, or VET qualifications at Certificate III+[web:14][web:18].
Western Australia (WACE):
Uses Tertiary Entrance Aggregate (TEA) from 4 best ATAR course scaled scores. From 2026, changes to increase to 4 × 100 = 400 maximum[web:23][web:26].

❓ Frequently Asked Questions
What is a good ATAR score?
An ATAR of 80+ is considered good (top 20%), 90+ is excellent (top 10%), and 95+ is outstanding (top 5%)[web:17]. However, "good" depends on your university course requirements - some competitive programs require 95+, while others accept 70+.
How is ATAR calculated?
ATAR is calculated by: (1) taking your raw subject scores, (2) scaling them to account for subject difficulty, (3) creating an aggregate from your best subjects (varies by state), and (4) converting this aggregate to a percentile rank[web:14][web:17]. The exact method differs slightly between states.
What ATAR do I need for Medicine?
Most Australian Medicine programs require an ATAR of 95-99.5+ for direct entry[web:27]. Graduate entry programs assess university GPA instead. Remember that Medicine also requires UCAT/GAMSAT scores and interviews - ATAR alone doesn't guarantee admission.
Can I convert IB to ATAR?
Yes - IB students in Australia receive an ATAR equivalent called a Combined Rank through the IBAS system. An IB score of 36 ≈ 91.45 ATAR, 40 ≈ 96.30 ATAR, and 45 ≈ 99.95 ATAR[web:4][web:10]. Use the conversion tables above for detailed equivalents.
Is GPA the same as ATAR?
No - ATAR is a percentile rank (0.00-99.95) used for high school students entering university, while GPA (0.0-4.0 or 0-7.0) measures university academic performance[web:27][web:28]. However, tertiary GPA can be converted to an ATAR equivalent for graduate program applications[web:31].
Does ATAR change each year?
Your ATAR doesn't change, but course cut-off ATARs can vary annually based on demand and applicant numbers. Subject scaling factors also change yearly to reflect cohort performance[web:14]. A 90 ATAR in 2025 is equivalent to a 90 ATAR in 2026, but course requirements may differ.
What subjects scale best for ATAR?
Generally, advanced mathematics and sciences scale well due to cohort performance. However, you should choose subjects you're passionate about - scoring highly in "lower-scaling" subjects is better than performing poorly in "high-scaling" ones. Scaling compensates for difficulty differences.
Can international students use ATAR?
ATAR is for Australian students completing Year 12 in Australia. International students apply with their own qualifications (IB, A-Levels, SAT, etc.), which universities convert to ATAR equivalents for admission purposes[web:21][web:10].

- IB to ATAR conversions are based on official UAC/VTAC/QTAC tables updated annually[web:4]
- For university applications, always use your official scores from UAC, VTAC, QTAC, TISC, or SATAC
- Subject prerequisites and additional requirements may apply beyond ATAR scores
- Changes to ATAR calculation methods may occur - check with your state's tertiary admission center[web:23][web:26]
