ATAR - Australian Tertiary Admission Rank Aggregate and Scaled Scores Questions and Answers — Questions and Answers
Question 1: A student in NSW has their scaled marks calculated. Their best 2 units of English total 85. Their next best 8 units from other subjects total 330. What is their Tertiary Entrance Aggregate?
- 41.5
- It cannot be determined without their raw marks.
- 415 (Correct answer)
- 330
Correct answer: 415
The aggregate is the simple sum of the scaled marks from the best 2 units of English and the next best 8 units. In this case, it is 85 + 330 = 415.
Question 2: In the ATAR scaling process, what does it signify if a subject's scaled mean is higher than its raw mean?
- The subject exam was easier than other subjects that year.
- The students taking the subject were, on average, a stronger academic cohort across all their studies. (Correct answer)
- The Tertiary Admissions Centre has determined the subject is more important for university study.
- Fewer students enrolled in the subject compared to the previous year.
Correct answer: The students taking the subject were, on average, a stronger academic cohort across all their studies.
Scaling is based on the overall academic performance of the students in a course. If the students in a course perform better, on average, in all their other subjects, it indicates a stronger cohort, and the scaled mean for that course will be higher than the raw mean.
Question 3: Which of the following statements best describes the relationship between a student's aggregate score and their final ATAR?
- A specific aggregate score guarantees the exact same ATAR every year.
- The ATAR is calculated by averaging the aggregate scores of all students in the state.
- The aggregate score is a direct percentage of the student's performance out of 100.
- The aggregate score is ranked against all other students' aggregates to determine a percentile position, which becomes the ATAR. (Correct answer)
Correct answer: The aggregate score is ranked against all other students' aggregates to determine a percentile position, which becomes the ATAR.
The ATAR is a rank, not a mark. After all aggregates are calculated, they are placed in order from highest to lowest. A percentile rank is then assigned, indicating a student's position relative to all other students in their cohort for that specific year.
Question 4: Two students receive the same high raw mark of 90 in two different subjects. Subject A's cohort is known to be exceptionally strong academically across all their subjects, while Subject B's cohort represents the state average. What is the most probable outcome for their scaled marks?
- The scaled mark for the student in Subject A will likely be higher than the scaled mark for the student in Subject B. (Correct answer)
- The scaled mark for the student in Subject B will likely be higher than the scaled mark for the student in Subject A.
- Both students will receive an identical scaled mark because their raw marks were the same.
- Both students' marks will be scaled down to the state average.
Correct answer: The scaled mark for the student in Subject A will likely be higher than the scaled mark for the student in Subject B.
A high mark in a subject with a stronger academic cohort (Subject A) is considered a greater achievement. The scaling process will likely adjust this mark to be higher than the mark from Subject B to ensure fairness and comparability across different courses.
Question 5: In the NSW/ACT system, the Tertiary Entrance Aggregate is calculated by summing the scaled marks from 10 units of study. What is the maximum possible aggregate score?
- 99.95
- 100
- 1000
- 500 (Correct answer)
Correct answer: 500
The maximum scaled mark for a single unit (e.g., half of a standard 2-unit course) is 50. The aggregate is based on 10 units. Therefore, the maximum possible aggregate is 10 units × 50 marks/unit = 500.
Question 6: What is the specific function of the aggregate score within the overall ATAR calculation process?
- To moderate a school's internal assessment marks against its external exam performance.
- To create a single numerical measure of a student's overall achievement that can be ranked against others. (Correct answer)
- It is the final rank reported to the student and universities.
- To determine a student's raw score average before scaling is applied.
Correct answer: To create a single numerical measure of a student's overall achievement that can be ranked against others.
The aggregate's primary purpose is to combine a student's performance across their best eligible scaled subjects into one number. This single score then allows for a fair and standardized ranking of all students, which ultimately produces the ATAR.
