An ATAR ranges from 99.95 to zero, and reports your rank position relative to all other students. It takes into account the number of students who sit the WACE examinations in any year and also the number of people of Year 12 school leaving age in the total population.

If you have an ATAR of 70.00, for example, it indicates that you've achieved as well as or better than 70% of the Year 12 school leaver age population in the state.

The ATAR allows the results of any WA student applying for university admission interstate to be directly compared with results in other states.

You need at least four scaled scores for an ATAR to be calculated. The ATAR is calculated from your Tertiary Entrance Aggregate (TEA).

Your TEA (Tertiary Entrance Aggregate) is the sum of your best four scaled scores plus 10% of your best Language Other Than English (LOTE) scaled score (if you have one), plus 10% of your scaled score (if you have one) Mathematics: Methods ATAR plus 10% of your scaled score (if you have one) Mathematics: Specialist ATAR based on the following rules:

• You can accumulate the scaled scores which contribute to your TEA over five consecutive years, but you can only count any subject or course once. If you repeat a course, we use your best score in that course.
• There are some unacceptable course combinations (check the admission requirements for your year). For these combinations, scores in both courses/subjects cannot both be used. We use your best score from the combination.
• If you have a scaled score in a Language Other Than English, 10% of your LOTE scaled score is added to the aggregate of your best four scaled scores. LOTE scaled scores must be from the current year or the previous four years. If you have more than one LOTE score, only one (the best) LOTE scaled score will be used as the LOTE bonus. You receive the LOTE bonus even if your LOTE course wasn't counted as one of your best four.
• If you have a scaled score in Mathematics Methods ATAR and/or Mathematics Specialist ATAR, 10% of your scaled score/s in these subjects will be added to your Tertiary Entrance Aggregate. You will receive this Mathematics bonus even if the course/s aren't in your best four.
• The maximum TEA is 430.

Your TEA will be calculated and then converted to an ATAR, which tells you where you're ranked relative to other students.

TEA calculation change for 2028
In 2028 TISC will update the way it calculates the Tertiary Entrance Aggregate (TEA) to increase consistency and fairness for all students in WA. Refer to our factsheets for further details.

If you've sat at least one WACE exam and achieved a scaled score in a WACE course this year, you'll be able to access your Year 12 examination results and ATAR on this website from late December.

Your Universities Admission Advice letter (UAAL) will contain this information. You can print or save the PDF of your UAAL for your own records until 1 March of the following year.

If you want a printed copy of your UAAL and/or an ATAR Certificate on official stationery, you can order one on payment of a fee.

You can obtain your ATAR and scaled scores from a past year by completing and submitting the Request Form - Statement of Results with the appropriate fee to TISC.
