How is scaling determined? (1 Viewer)

[lyounamu]

People say that scaling reflects the quality of the students. But how do they determine the "quality" of the students in the first place?

I would really appreciate if someone could come up with an explanation and some sources to back it up.

By comparing how students go in all their subjects.

is namu talking about scaling as the scaling of aligned marks by the uac or moderation for individual subjects?

I assumed he was referring to scaling not moderation because the quality of the students affect the process and is often referred to.

I am talking about the scaling of aligned marks. How do they determine it?

Someone said earlier that it is determined by comparing candidature, how do they do it? What's the benchmark?

The scaling model assumes that a student's position in a course depends on the students ability in that course and the 'strenght of the competition'. Since the UAI is a rank, 'strength of competition' is defined in terms of the demonstrated overall academic attainment of a course candidature.

Scaling first modifies the mean, the standard deviation and the maximum mark in each course. Adjustments are then made to the marks of individual students to produce scaled marks, which are pretty much the marks they would have recieved if all the courses had the same cnandiature.

Then aggregates are calculated based on the scaled raw marks.

So the benchmark is the mean, the standard deviation and the maximum mark for each course.
