WACE ATAR Calculator
WACE ATAR students study courses across Year 11 and Year 12, with final ATAR courses producing a mark out of 100 combining school assessment and an external exam (usually 50/50). TISC scales these marks to make them comparable across subjects, takes the best 4 scaled scores, and adds a 10% bonus for Maths Methods, Specialist Maths, and LOTE courses. This Tertiary Entrance Aggregate (TEA) is then converted into an ATAR — a percentile rank from 0.00 to 99.95.

Aggregation
In Western Australia, ATAR courses (studied in Year 11 and Year 12) produce a score from 0 to 100. TISC scales these scores to account for subject difficulty, then calculates your Tertiary Entrance Aggregate (TEA) from your best 4 scaled scores. You also receive a 10% bonus for Mathematics Methods, Specialist Mathematics, and Languages Other Than English (LOTE) courses if they are in your best 4. The TEA is then converted to an ATAR.
This chart shows the approximate scaled score at a raw midpoint score for each subject. Subjects above the dotted line scale up (harder subjects), below scale down (easier subjects).
Based on approximate scaling data. Actual scaling varies by year and cohort.

Remember: Scoring well in a subject you enjoy will almost always beat scoring poorly in a "better scaling" subject. Choose subjects you're genuinely interested in.
