WACE ATAR Calculator (WA, 2026)

Enter your scaled scores and get your TEA and an indicative ATAR — computed exactly the way TISC does it: best four scaled scores, plus the 10% language and Mathematics bonuses, converted through TISC’s official TEA-to-ATAR table. WA is the one state where this is honestly possible, because TISC publishes the conversion table itself.

Estimates use TISC’s 2025 TEA→ATAR table — the official 2026 conversion is published when ATARs are released in late December 2026, and the mapping shifts slightly each year. The 10% bonuses (best language, Mathematics Methods, Mathematics Specialist) and TISC’s unacceptable-combination rules are applied automatically from the courses you select; both are per TISC’s published admission requirements for the 2026 and 2027 cohorts. Not a guarantee — always confirm with TISC.

The official TEA→ATAR anchors (2025)

Selected anchors from TISC official 2025 TEA/ATAR summary table (Australian Tertiary Admission Rank — ATAR & Tertiary Entrance Aggregate — TEA). The calculator interpolates between every published anchor.

Source: TISC — ATAR & TEA. Indicative only. The official TEA→ATAR conversion is recomputed every year against that year's cohort; the 2026 table publishes ~late December 2026. Use this 2025 table as a guide, not an exact prediction of a 2026 ATAR.

Where do scaled scores come from?

Your school marks and exam marks are combined, standardised and scaled by SCSA and TISC — the scaled score (out of 100) reflects how you ranked in each course, with the average across all courses fixed at 60. See how every WA course scaled in 2025 to gauge realistic scaled scores for your subjects, and how the WACE ATAR is calculated for the full method.

FAQ

How does the WACE ATAR calculator work?

It applies TISC's official pipeline: your best four scaled scores are summed, 10% bonuses are added for your best language (LOTE), Mathematics Methods and Mathematics Specialist, giving your TEA (maximum 430). The TEA is then converted to an indicative ATAR using TISC's published TEA-to-ATAR table.

Why does it ask for scaled scores instead of raw marks?

WA standardises and scales your combined marks before they reach TISC, and no raw-mark-to-scaled-score conversion is published — so any calculator that starts from raw marks is guessing. Scaled scores in, official table out, is the honest method.

How accurate is the estimated ATAR?

The TEA-to-ATAR table is rebuilt against each year's cohort, so this tool uses the most recent official table (2025) and interpolates between its published anchors. Treat the result as indicative — the official 2026 conversion is published by TISC when ATARs are released in late December 2026.

Are the 10% bonuses included?

Yes. The calculator automatically adds 10% of your best language (LOTE) scaled score, 10% of Mathematics Methods and 10% of Mathematics Specialist — even when the bonus course isn't in your best four, matching TISC's rule for the 2026 and 2027 cohorts. A proposal to remove the bonuses was postponed by TISC in March 2026 until further notice.
