Australian Tertiary Admission Rank

The Australian Tertiary Admission Rank (ATAR) is the primary criterion for entry into most undergraduate-entry university programs in Australia. It was gradually introduced during 2009 and 2010 to replace the Universities Admission Index, Equivalent National Tertiary Entrance Rank and Tertiary Entrance Rank. Queensland still retains its own separate Overall Position system, but will begin using the national ATAR system in 2018.

ATAR is derived from mapping a student's aggregate score to the national averages. A student's aggregate score can be calculated using the following formula:

${\displaystyle A=S_{E}+S_{3}+10\%\times S_{2}}$

where ${\displaystyle A}$ is their aggregate score; ${\displaystyle S_{E}}$ is their English percentage; ${\displaystyle S_{3}}$ is the sum of their three best percentages; and ${\displaystyle S_{2}}$ is the sum of their two worst percentages. Since ATAR is based on averages, a new table is published each year for mapping aggregate scores to ATAR (e.g. 220 aggregate = 95 ATAR).
