How does this all work?? (1 Viewer)

[deyveed]

Ok. I've heard a few stories of how UAIs are calculated and im wondering which ones are true, if any, and what really happens.

1. BOS only take the RANKS of students to use for scaling the HSC mark and ignores the school's assessment marks.

2. UAC uses the SCALED BOS marks to SCALE again to index students.

3. If you fall below a certain percentile (depends on subject), you will either scale up/down or stay with the mark.

4. School's do not have a scaled mean or anything. So an easy Chem exam in a selective school is pretty close to hard Chem exam in a non-selective school.

Now, if Chem and Eco are regarded as high scaling subjects by UAC, does that mean that it they are hard compared to other subjects or the quality of the candiature is high or a mixture of both?


Thanks

Ok. What i mean by No. 4 is that do schools have a fixed ratio to which all its assessment marks are scaled against? So every year when Ruse gets a high scaled ratio in a subject, all the students doing that subject get the same advantage no matter how big the marks range.

One more rumour to clear up:

5. Even if a student is top of the state material, going to a below average school will affect his/her mark and rank.

Ok. For 4, what i mean is that do schools have a "scaled mean" just like the "scaled mean" for subjects that UAC releases? Or is it totally mumbo jumbo and everyone gets their marks scaled differently and separately?


How are school assessment marks moderated?
Do they look at the school's HSC marks and assessment marks and somehow get an average or something?
How do they determine that Ruse students are so smart and other schools with similar marks are not?


Thanks Cyph

5 - if the student is ranked first in the subject, then they will not be affected by the rest of their class. The student ranked first in a subject gets the highest exam mark as their moderated assessment mark (which is often their own, but not always) and their exam mark. So if a student who is top of the state material is ranked first in the worst school, they will be unaffected. If they were ranked anything other than first, then they're obviously going to be affected since their moderated assessment mark will depend on how the rest of the class performs.


what if i go well in my hsc exam....but my school rank isnt, and school's overall performance is poor.

In theory, this is true, but in practice, you can never know what the percentile is, as raw marks aren't published (and you can't know whether a mark was 'scaled up' or 'scaled down' without knowing the original mark).

I'm sure this has been asked before...

1) Your exam mark will ALWAYS* be your exam mark.

If you do well in your HSC exam, you'll get a mark which reflects your performance.

2) Your moderated assessment mark is determined by your position relative to the other students at your school and the performance of your school on the HSC exam.

If your school rank is poor, and your school's overall performance is poor, your moderated assessment mark is going to be poor (surely this is logical ).

Your HSC mark is the average of the above two marks.

Think of your school earning a pool of marks for a particular subject when they sit the HSC exam. This pool of marks is the total of every student's exam mark.

This pool of marks is then distributed amongst students according to their rank and relative difference between other students. The higher a student is ranked and the greater the relative difference between students below them, the more marks they'll get assigned. The opposite is true for students towards the bottom.

The student ranked first in school assessment mark gets the highest exam mark as their moderated assessment mark (which may or may not be their own), they then get their *own* actual mark they got in the exam as their exam mark. The average of this is then taken to give their HSC mark.

In summary, a good ranking and a strong performance by you in the HSC exam is what determines your moderated assessment mark, not the marks you earn in assessments at school.

Ok. What if i was ranked very very low in a subject but during the holidays (stuvac i think its called) i revise and master my subject and get 100% in the HSC exam (1st in school) for that subject? Would i just be pouring more marks into the pool and giving the guy that came first in my school more moderated assessment marks?

 

[Ragerunner]

as he said your HSC is the average of the 2.

if you do poorly in the school assessments say 60. but own it up in the exam and get 90, you HSC mark will be 75.

and 75 isn't considered 'very' good. which is why bos say in order to do good in the hsc you must be consistent throughout the year.

Ok. Im beginning to understand this i think.

Say there are 2 students in the school. Student A gets 100% for his school assessment mark for a subject and student B gets 50%. In the HSC exam, they both score 100% each for that subject giving the 'pool' a total of 200 marks between them. Does student A get 100% for the assessment mark and student B get something less than 100?

If that is the case, what happens to the rest of the marks the school has earned?

 

[Ragerunner]

because there are 2 people in the class and both got 100% then both their HSC mark will be 100%. thats why the HSC exam is really THAT important.

 

[deyveed]

i understand that both get 100% for their HSC exam mark but what about their assessment mark?

 

[Lazarus]

The HSC mark is the average of the moderated assessment mark and the aligned exam mark - this is what Ragerunner was referring to (implying that each of the two components of the HSC mark would be 100%).
