There can be no doubt that the VCAA assess English (and all other subjects for that matter) according to their published guidelines.
I understand that the next to last step in the assessment process is to RANK each of the 40,000 students who attempt VCE English.
Therefore there will be a student who ranks 1, 2 ... all the way to 40,000
The system also allows for equal ranks. For instance, 2 students score equally at the top end, and they are both assigned a rank of 1, the next best is assigned a rank of 3, and so on down to rank 40,000
It is the normalised RANK (scale 0-50) which produces the final Study Score.
But with a cohort as large as that of VCE English, there will be literally hundreds of students who will share the same rank . Lets face it, how many different combinations of 8/9/10's can there be?
Therefore, even after your exam score is combined with your SAC score, there will still be many students who will share the same rank.
I can therefore envisage some practical reasons for a further 'finer and subjective' gradation of results.
This can be illustrated with the following (contrived) example:
In 2011, a combined total of 100 students will be assigned study scores of 48, 49 and 50.
It just happened that 100 students got the exact same score (SAC + Exam) and they are all ranked equal #1.
Surely, these 100 students will need to be differentiated, and this can only be done after the fact, meaning that some will be (subjectively, if you like) judged better than others
I do not profess 'inside' knowledge.
I have none.
Just thinking aloud.
