How the WA ATAR works

• Your TEA is the sum of your best four scaled scores (each out of 100).
• Plus 10% bonuses of your Mathematics Methods, Mathematics Specialist and best Language (LOTE) scaled scores, even if they are not in your best four.
• The maximum TEA is 430. TISC then converts your TEA to an ATAR, which is a rank, not a mark.

This is an estimate only. It uses the 2025 TISC TEA-to-ATAR table, which changes each year, and assumes you enter scaled scores. School percentages are not scaled scores: scaling can move a mark up or down depending on the course and the cohort. Unacceptable course combinations are not checked. Your official ATAR comes from TISC in December.
