ATAR to Replace All UAI's

The UAC announced earlier this month that the UAI system will be replaced by the ATAR (Australian Tertiary Admissions Rank). The conversion of UAI to ATAR aligns NSW’s system of measuring HSC performance for the purpose of university admissions to that of other states. The ATAR will replace all UAI’s, starting with the year 12 students in 2009, and will be a rank-based score out of 99.95 (instead of 100.00).

How will the ATAR affect me?uai-to-atar-score1 The ATAR is a similar (but not identical) rank-based scale used to differentiate student performance for the purpose of university admissions. Like the UAI, the ATAR is a rank-based index, meaning the same rules of HSC scaling would apply under the ATAR.

Students should remember that just like under the UAI system, it is your rank relative to other HSC students which determine what ATAR / UAI you will receive. That is, based on your aggregate mark (out of 500), your percentile position will be calculated, and this will be directly converted into an ATAR. As a result, the number will change when converting from UAI to ATAR, however your rank remains the same. As a result, university ATAR cut-offs for all courses will be converted to match the previous equivalent rank cut-off.

For example, say Bachelor of Commerce at UNSW has a UAI cut-off of 90.00. Say this translates to a rank cut-off at the 8,800th student from the top rank. The ATAR cut-off would be adjusted to match the rank, and not be converted according to some arbitrary process. E.g. according to UAC’s published UAI to ATAR conversion table, a UAI of 90 converts to an ATAR of 90.80.

Converting from UAI to ATAR score

Because both the UAI and the ATAR are rank-based scores, they are directly comparable to previous years’ UAI scores. So if you have an older brother or sister and want to best them in the HSC, the implementation of the ATAR system won’t affect that! Notice that the highest attainable ATAR is 99.95 (instead of a UAI of 100). As a result, UAI’s near 100 (above 99.7) are converted to a slightly lower ATAR score, and all UAI’s lower than 99.2 are converted to a slightly higher ATAR. For the vast majority of students, this makes their university entrance score look slightly better! However, again we remind you that your rank is not affected by these changes, and therefore the difference in numbers between the ATAR and UAI make no difference to you.
