Statistical Moderation for Shared SAC Marks

(1/1)

dcc:
Hey, I just have a question to pose to you all, I hope somebody out there can enlighten me :)

Consider this example:

In a cohort of 80 students for a subject, there are 7 people on 100% SAC markings (i.e. they all have 100/100 internal scores).  How do VCAA deal with moderating these SAC marks if the 7 people get wildly differing exam marks.  For example, 1 student gets 100%, another gets 95% the rest get 80%, what will their moderated SAC marks become? Can they be different for each person, or will they all have to be equal?

Glockmeister:
I would be lead to believe that the SAC rankings would be adjusted based on the exam marks. So the person who got 100% would rank first, and then the 95% and so on.

sadly, they will be equal [and i take my sources to be correct, though i cannot reveal them]

this is the reason why your teacher MUST rank you. there has been a case with a particular school that had four equal-firsts, and the teacher has placed them equal-firsts [rather than giving a rank], the result was one of them was significantly disadvantaged [this is why you shouldn't have easy SACs, and why MHS have extraordinarily hard ones]

yes, this part DOES suck.
