Atar Calculation (1 Viewer)

Hey guys,

I just wanted to know if the atar aggregate table provided by UAC is based on HSC marks or raw marks.

Thanks.

Raw mark is the mark that is attained after the exam has been marked; eg. you do say a 3 unit maths exam, and you get 63/84 - that is your raw mark. Now, this mark is not released to you. First the board of studies aligns the raw mark according to standards, so since 3 unit maths aligns very well, 63/84 aligns to ~92/100 (or 46/50). That is your aligned exam mark. Next, the BOS moderates and aligns your assessment marks, and then averages them with your aligned exam marks - eg. if your moderated/aligned assessment mark was say 88/100 (or 44/50) and aligned exam is 92/100, they do (92+88)/2 = 90 <-- THAT is your HSC mark.

Scaled marks work differently - the UAC takes your RAW exam marks and moderated assessment marks (before aligning), and scale them based on the scaled mean (average) of how the whole state performs - the higher the scaled mean, the better the subject scales; eg. in 2010, 3 unit maths had a scaled mean of 39.8/50 (or 79.6/100), this means it scales extremely well. It is usually the case that the scaled marks are much lower than your raw marks. Another example is Standard English; in 2010, it had a scaled mean of 17.3/50 (34.6/100), this means it scales very poorly, and hence can scale you down pretty badly if you don't perform that well in it. Remember, aligned marks have NOTHING to do with scaling - they are not used in the calculation of your ATAR.

But aligned marks are not taken into consideration while calculating atars, are they?

The alignment process has nothing got to do with the ATAR calculation. Alignment will determine what performance band your HSC marks fall into, they have no bearing on your ATAR. However both are derived from your raw school marks and raw external exam marks, so students who get high ATARs also get high aligned HSC marks.

It is based on the addition of scaled marks.

Just in case it is unclear, the answer to your question is NEITHER.

The aggregate is a total of your SCALED marks, and you never see those.

The scaled marks and the HSC marks are each calculated from you raw marks by independent processes.
