What you just talked about is the moderating processAntiHyper said:Here's what my dep. principal told us:
Say there's 3 ppl in the class Bob, Jane & John
In the overall assessments mark, Bob came 1st Jane came 2nd & John came 3rd
Then in the exam John came 1st with 92, Bob came 2nd with 88 & Jane came 3rd with 76.
Now Bob would actually get 92, Jane get 88 & John get 76.
The rest is just the averages.
Wait a sec... Ur talking about scaling eh... I think (hope) this would answer some parts of scaling...
As far as I know, yes although you'd need to ask Laz.wrx said:UAC scales the marks right?

BOS aligns and moderates marks for reporting. UAC scales marks and determines UAIs.
That'd be me.k_m said:whos lazarus?
The Technical Committee on Scaling performs the actual computations and then provides the resulting UAIs to UAC.wrx said:UAC scales the marks right?
You should first familiarise yourself with the You and Your UAI booklet and <a href="/other/flowchart.pdf">this flowchart</a>.k_m said:how does scaling work?
Oh, you mean like me?ogmzergrush said:Sort of like Jesus, without the entire nailed to a cross thing.

Then search the forums or come back to us with more specific questions.
The aligning of raw exam marks occurs in order to take into account the varying difficulty of exams from year to year e.g. 2U maths in 2003 was harder than the 2004 exam. Therefore, aligning makes 2003 and 2004 marks comparable, or else 2003 students would be disadvantaged.k_m said:i was wondering y do they align the raw external examination mark?????
Scaling is not based on the difficulty of the exam, but rather the quality of the candidature. Even though Business Studies may be a difficult subject, the students who do it generally aren't the most capable students in the state. Hence, it gets scaled down. Scaling basically observes the ease of which an average student can get into the top 50% e.g. it's much easier to get into the top 50% of Business Studies than it is to get into the top 50% of Physics, since the students who do Physics are generally more able than those who do Business Studies.k_m said:y is business studies scaled down, it seems like a hard subject?
No probs, although I'm no Lazarus by any means...k_m said:thanks 4 answering my questions Rench![]()

To your first question, I believe that is because the HSC marks reported to students are subjected to a process which slightly distorts the actual performance.Trebla said:Some Questions:
I don't see why the raw marks have to used for scaling. Since aligning is done to supposedly even out the distribution of marks in comparison to previous sucessive years, why not use that mark, since it is more "fair"?
Also, Why are some courses "capped"?
Plus, I've noticed on the UAC website (http://www.uac.edu.au/pubs/pdf/2004-Table-A3.pdf) that the scaled mark in MOST cases is lower than the HSC mark, but for some courses like Mathematics Extension 1, the 50th and 25th percentiles have scaled marks higher than their HSC mark, but the 99th, 90th and 75th percentiles have their scaled marks lower than their HSC mark. Why is that the case? Shouldn't higher percentiles have higher scaled marks in relation to their HSC mark compared to those in the lower percentiles? Is this where capping comes in?
To Trebla:Captain pi said:Remember that, either way, if you get a higher HSC mark, you are going to get a higher scaled mark.
Yes. It's what I meant but was not made sufficiently clear.~ ReNcH ~ said:To Trebla:
That's provided that you're comparing HSC marks within the same subject. HSC marks are not comparable between subjects. So getting a 95 in Business Studies and a 93 in Physics does not necessarily mean that you're scaled mark for Business will be higher than Physics.
