Raw band cut-offs. (Updated: 15/09/04) (1 Viewer)

[Lorie]

so what is a band 6 - a raw mark over 90 or a rank in the top 10% or a scaled mark over 90

None of the above.

It is an aligned mark of 90+, and a raw mark of X, where X is a raw mark above the band 6 cut-off for that particular course in that particular year.

The performance bands have nothing to do with percentile rankings or scaled marks.

 

[Shifty]

Meaning to say that if I receive 60/100 for the HSC exam for Physics, that is effectively 80/100 aligned HSC mark. ie 60% gets boosted up to 80% for physics.

is that a yes or a no??

 

[Lazarus]

Superbird's statement was correct, but ONLY with regard to 2003.

Raw band cut-offs are not fixed. They will vary each year according to the difficulty of the examination paper.

 

[Lazarus]

What they should have said was that your moderated assessment mark is set equal to (for example) the fifth examination mark.

But it's not exactly equal anyway - the two marks should be similar, if the distributions are similar.

Your exam mark will always be your exam mark. This doesn't depend on anything else.

And your HSC mark is the average of your moderated assessment mark and your exam mark.

See this thread and this flowchart.

Physics
100/100..............100/100

90/100..................78/100

80/100...................72/100

Is there seriously only 6 marks distinction between 80 and 90? Or is that a typo?

 

[Survivor39]

No it's not a typo I don't think. Laz triple checks everything before he posts. lol

There were probably a lot of students fell into the 70's raw and they believe a cut off there would somehow indicate their abililities in a band 5 performance, and anything lower than a 72 would be considered a band 4.

 

[Lazarus]

Is there seriously only 6 marks distinction between 80 and 90?

That was the case in 2001, though the cut-offs obviously vary each year.

It can also go the other way - see, for example, English Extension 1, where a range of 16 raw marks was compressed to a range of 5 aligned marks.

so Lazarus, using ur example where u get a raw mark of 56/100 for physics, and it gets aligned to 78/100 this 78 is the mark they put on ur mark sheet or wateva that the board of studies posts out to say uve completed hsc blah blah blah
then UAI people get ur raw mark of 56/100 and physics gets reasonably scaled so does it get scaled up a fair bit to the 70s? or does it get scaled down, but not scaled down as much as some crappy subjects like DT.... ?

Yep - exactly right.

That mark of 56/100 in Physics would have been scaled up to around 68/100.
(You can check this by entering 78 for Physics in 2003 using SAM.)

 

[matt_f64]

ok im starting to understand!!! so if my exam marks for all my subjects were say 70, and they were all on the same scaling level as physics, then my aligned mark would actually be say 85 (i dont no exactly but u get the point) and then my scaled mark for the UAI would be say 68 or somethin.???
cos most of my subjects get scaled up... physics, economics, adv eng, 2uMaths... and im looking at gettin into the low 80s for all my subjects, so wud that mean my aligned marks would all be closer to the 90s, and i can put aligned marks closer to the 90s in SAM ?

 

[matt_f64]

actually in the above post, take the scaled mark of 68 to be 78 . sorry

 

[ay_caramba]

Thanx. I feel a bit more confident abt maths now

 

[matt_f64]

Lazarus?? please check the PM i sent u, thanx

 

[Plebeian]

Yep - exactly right.

That mark of 56/100 in Physics would have been scaled up to around 68/100.
(You can check this by entering 78 for Physics in 2003 using SAM.)

So does SAM take the aligned mark for a year, work out what the raw mark would have been, and then apply scaling to figure out your UAI? (If that's not a trade secret)

 

[matt_f64]

thats pretty much correct

 

[Plebeian]

How did you know? The question was generally directed at Lazarus.

selective high school

i go to penrith high school which is a selective high school... my rank for most of the subjects is average or just below average... i was wondering that i am disadvantaged by going to a selective high school because my rank was low when i could of been better off going to my local high and getting like first or second in every course...

thanks

 

[Plebeian]

This should perhaps go in another thread, but generally the answer is no. Part of the point of moderating is to solve this problem. Going to a selective school should also help you out if you mess up the exam, because the rest of your cohort will pull you up somewhat, whereas if you were the only good student at a school, and you messed up, you'd be stuffed.

 

[googleplex]

so did you just assume 100 in those subjects went to 100, or did someone you know get 100 raw ? D:
