Calculation of the ATAR
The ATAR is a rank based on an aggregate of scaled marks in 10 units of ATAR courses comprising a student’s:
- best two units of English
- best eight units from their remaining units, which can include no more than two units of Category B courses.
Although eligibility for an ATAR requires completion of at least four subjects, the aggregate may be based on less than four subjects, for example English Advanced, English Extension 1 and Extension 2, Mathematics Extension 1 and Extension 2, and one other 2-unit course.
Marks to be included in the ATAR calculations can be accumulated over a five-year period but if a course is repeated, only the last satisfactory attempt is used in the calculation of the ATAR.
Scaled marks are calculated the year the courses are completed.
