The Interstate transfer index (ITI) presents the State Tertiary Entrance Ranks from all years in a comparable fashion, allowing better analysis of difference between states. Since 1998, all states and territories, except for Queensland, have adopted the ITI as the state measure of student achievement, but with different names (see the definition of state's Tertiary Entrance Ranks for each name). This means that the measure in NSW, ACT, VIC, SA, NT WA, and TAS are exactly the same. From 2020, Queensland has also adopted the ITI as the state measure of student achievement. Prior to 2020, the Queensland OP was mapped to the ITI using an agreed scale. While ITI is the term used by the TACs the more widely used term is Australian Tertiary Admission Rank (ATAR).
