看来我错了,是这样的,大学录取用UAI
Calculation In NSW
To calculate the UAI the UAC uses the raw exam marks of the HSC and the moderated assessment mark.
The assessment mark is that obtained from the internal school examinations a student sits over the last term of year 11 and the three terms of year 12. The school marks are sent to the UAC from the Board of Studies, and from these students are ranked from first to last. The student ranked first is then assigned a moderated assessment mark equal to the highest examination mark scored by that group of students, regardless of who scored it, and similarly the student ranked last will receive the lowest examination mark. The rest of the students have their assessment marks moderated between these two values, with the proportional difference between the marks remaining the same (for instance, the gap of 10 between two marks spread over a range of 20% will be halved if the range is halved to 10%).
The student who comes first in the subject is then assigned the maximum mark, normally 50.0 on a one unit basis but may change with scaling. Following that all students who sat the course have a scaled mark calculated based on an estimate of what each student would have achieved had they sat that course. This is repeated for all of a student's units.
The student's two best English units are added along with their next best eight units, which may include further English units, to give an aggregate mark, out of 500.0. Students are then ranked - however, this rank does not translate directly to the UAI. The distribution of students is uneven. Ranking scales upwards - only 29.3% of students will receive a UAI of under 50, and the median UAI is around 65, a statistical trend which is applicable at every UAI level. This is because the spread of marks takes into account those who did not complete their HSC or otherwise attend the post-compulsory years of education. Their hypothetical marks are determined by the School Certificate, one compulsory for all students in NSW. As their marks are generally lower than those who complete the HSC, they cause the uneven spread across the spectrum of the UAI. Hypothetically, assuming that everyone continued to complete the HSC, the spread would be completely even. However, NSW retention rates for students stand at around 70%, and there are students who complete the final years without gaining an HSC. |
