ATAR Calculation Question (1 Viewer)

[heatskillz]

hi guys sorry im new and i dont know how to post a message so i thought ill ask here , i was wondering on how the ATAR is calculated.. basically im sitting for my hsc next year, is ATAR calculated by my rank in school say im coming 2 in 2u maths with a mark of 80 for my assessments all together and in the hsc i get a 50 does my mark get pulled to 80 ? (is it based on my rank).. and is it possible that i get in the 80s for my ATAR im doing well so far in all subjects i came 1st 2nd and 4th, my subjects are

english standard
2u maths
physics
modern history
visual arts
Thank you!

The process is explained in depth here: http://www.boardofstudies.nsw.edu.au/hsc-results/moderation.html. Also, you can get any ATAR with almost any combination of subjects. There are some exceptions but your combination is fine.

You get two marks which determine your final HSC mark - moderated assessment mark (internal) and HSC exam mark (external).

Your external mark is the mark you get in the HSC. This is your own performance; it can't change based on someone else's performance etc.

Your internal mark is a mark which reflects your school performance. This mark is moderated, or more simply, "scaled" according to how your cohort/class performs in the HSC. Now, throughout the year, you sit many assessments. These determine your raw internal mark. This mark must be moderated because your school might set easy assessments or very hard assessments. If your cohort gains marks between 90 and down to 50, then ALL internal marks will range from 90 down to 50.

The mark you get will be proportional to those range of marks. Rank isn't much important now. Coming second by 20 raw marks is very much different to coming second by 5 raw marks. Coming second by 20 raw marks might mean your internal mark is 67 (example), by coming second by 5 raw marks might mean your internal mark is 87.

So if in the HSC exam, you achieve 50, then that's set. Nothing can change that. That 80 you achieved in school will be changed according to your cohort's performance. It could be changed to 60 or up to 90. We can't tell. That is why doing well in the HSC as a cohort is very important.

how do they calculate my ATAR.

Re: how do they calculate my ATAR.

what ive heard its 50/50 from your school mark and hsc mark
now the school mark is comprised of assignments trials etc all that school stuff, now i dont think your previous school rank matters its only on how smart your cohort is
so at the end of the trials or school based stuff you get a rank eg 1,2,3
then when you sit the hsc you get a mark eg 90,93,94
say rank 1 got 90 in hsc, but since he came first the school based mark would take number 1 hsc mark from your school so 90+94 divide by 2 so his final mark is 92
then rank 2 got 93 in hsc and will get the 2nd highest hsc mark for assessment so 93 all up
rank 3 would get 94+90 divide 2 so final mark of 92
correct me if im wrong but this is what ive been told

ATAR is an aggregate of your best 10 units (with 2 compulsory units being English). Here's a personalised example; say for instance You, Elmo, and Cookie Monster go to the same school. It's HSC time hooooray!

Elmo is ranked 1st at school whilst You are 2nd and Cookie Monster is 3rd.
Elmo in the HSC exam gets an external mark for 2U Maths of 45, Your mark is 50 and Cookie Monster's is 48.

You will have an external mark of 50 and internal mark of 48, overall = 49
Elmo will have an external mark of 45 and internal mark of 50, overall = 48
Cookie Monster will have an external mark of 48 and internal mark of 45, overall = 47

With the exception of being a really crappy school, you can ascertain that rank is very important and no where in the example has the mark been raised to 80, to reflect the internal assessment mark. Hence internal marks derive from ranks (moderation).

Will you get 80 ATAR? No idea and not relevant at this stage [being in Year 11]. However when the time comes, feel free to hit a new post with your subject ranks and school rank.

ATAR is calculated through your best 10 scaled units.

UAC (the company that derives your ATAR) uses a method of aggregation which ranks students from 1st to last. This is a mark out of 500. To determine that mark, they use your raw HSC mark (which reflects performance in the state) and your moderated assessment mark (which reflects your rank in the state). These are then "scaled" to ascertain some certain score for that subject. This is not the average of your marks; this is not the method the Board of Studies uses. Then, your scores are added up and it will be a score out of 500. Then, the top 45-50 students will achieve 99.95, the next 45 or so will get 99.90 and so on down to 30 ATAR.

Don't get ATAR confused with HSC mark. HSC marks use aligning, ATAR scores use scaling. The final HSC mark has no bearing on ATAR calculations.
