ATAR - Australian Tertiary Admission Rank ATAR Calculation Fundamentals Questions and Answers — Questions and Answers
Question 1: What is the primary purpose of the scaling process in the calculation of the Australian Tertiary Admission Rank (ATAR)?
- To increase the raw marks of students who perform well in difficult subjects.
- To ensure that a student's ATAR is not unfairly influenced by their choice of subjects. (Correct answer)
- To rank students based on their raw examination scores before any adjustments.
- To convert the final ATAR into a percentage score out of 100.
Correct answer: To ensure that a student's ATAR is not unfairly influenced by their choice of subjects.
The fundamental principle of scaling is to ensure that students are neither advantaged nor disadvantaged by their subject choices. It adjusts raw marks to account for the varying difficulty and academic strength of the student cohort in different subjects, allowing for a fair comparison of overall performance.
Question 2: A student in NSW receives their Higher School Certificate (HSC) results. Which combination of scaled marks will be used by the Universities Admissions Centre (UAC) to calculate their ATAR aggregate?
- The best 10 units regardless of the subject.
- The best 8 units, plus the two compulsory Mathematics units.
- The best 2 units of English, plus the next best 8 units from remaining courses. (Correct answer)
- All units studied, with each unit weighted equally.
Correct answer: The best 2 units of English, plus the next best 8 units from remaining courses.
In New South Wales, the ATAR aggregate is calculated from the scaled marks of 10 units of HSC courses. This specifically comprises the student's best 2 units of English and the best 8 units from their remaining eligible courses.
Question 3: An ATAR of 85.00 signifies that a student has:
- Achieved an average score of 85% across all their subjects.
- Performed better than 85% of their Year 12 cohort.
- Scored in the top 85% of all students in their age group.
- Achieved a rank in the top 15% of their student age group population. (Correct answer)
Correct answer: Achieved a rank in the top 15% of their student age group population.
The ATAR is a percentile rank, not a score. An ATAR of 85.00 indicates that the student's overall academic achievement places them in the top 15% of their entire age cohort (not just the students who completed Year 12), meaning they performed as well as or better than 85% of that population.
Question 4: Which of the following statements about the Tertiary Entrance Aggregate (TEA) in Western Australia is correct?
- It is the average of a student's best four scaled scores.
- It is calculated solely from a student's final examination marks, excluding school assessments.
- It can include bonuses, such as 10% of the scaled score for a Language Other Than English (LOTE). (Correct answer)
- It is the direct equivalent of the ATAR, just with a different name.
Correct answer: It can include bonuses, such as 10% of the scaled score for a Language Other Than English (LOTE).
In Western Australia, the Tertiary Entrance Aggregate (TEA) is the sum of the student's best four scaled scores. Importantly, it can also include a bonus of 10% of the scaled score for a LOTE, as well as for Mathematics Methods and Mathematics Specialist subjects. The TEA is then used to determine the ATAR, but it is not the rank itself.
Question 5: A student is concerned that choosing a subject with a historically lower-scaling average will disadvantage them. What is the underlying principle of ATAR calculation that addresses this concern?
- Subject ranking, where only the student's rank within the school matters.
- The aggregate system, which focuses only on the top-performing subjects.
- The scaling process, which aims to neutralize the advantage or disadvantage of subject choice. (Correct answer)
- Moderation of school-based assessments, which aligns all school marks to a common standard.
Correct answer: The scaling process, which aims to neutralize the advantage or disadvantage of subject choice.
The core purpose of scaling is to ensure equity. It adjusts marks based on the overall academic strength of the cohort in each subject. This means a student is neither advantaged for choosing a subject that scales high nor disadvantaged for choosing one that scales lower. The goal is to estimate what a student's mark would have been if all students had taken all subjects.
Question 6: What is the relationship between a student's raw HSC marks and the scaled marks used for the ATAR calculation?
- They are identical; raw marks are used directly to calculate the ATAR.
- Scaled marks are always higher than the raw HSC marks.
- Raw marks are converted to scaled marks to allow for fair comparison across different subjects. (Correct answer)
- Only the top raw mark from any subject is scaled for the ATAR.
Correct answer: Raw marks are converted to scaled marks to allow for fair comparison across different subjects.
Raw HSC marks for a subject reflect a student's performance against others in that same subject. To compare performance across different subjects fairly, these raw marks are adjusted through a process called scaling. This process accounts for the fact that the strength of the competition can vary between subjects, resulting in scaled marks that can be higher or lower than the original HSC marks.
