ATAR - Australian Tertiary Admission Rank Subject Scaling and Moderation Questions and Answers — Questions and Answers
Question 1: What is the primary purpose of subject scaling in the calculation of the Australian Tertiary Admission Rank (ATAR)?
- To reward students for choosing subjects that are perceived as more difficult.
- To ensure that a student's final rank is not unfairly advantaged or disadvantaged by their choice of subjects. (Correct answer)
- To adjust a student's raw exam scores based on their school's historical academic performance.
- To combine a student's internal assessment marks with their final exam mark for each subject.
Correct answer: To ensure that a student's final rank is not unfairly advantaged or disadvantaged by their choice of subjects.
The fundamental purpose of scaling is to allow for a fair comparison of student performance across different subjects. It adjusts raw scores to account for the varying difficulty and competitiveness of different courses, ensuring that students are neither advantaged nor disadvantaged by their subject selection.
Question 2: A student performs exceptionally well in a subject that historically scales down. Which of the following statements is most accurate regarding the impact on their ATAR?
- Their high mark will be significantly reduced, negatively impacting their ATAR regardless of their performance.
- The subject will automatically be excluded from their top aggregate score.
- A high raw mark in a lower-scaling subject can still contribute more to their ATAR than a poor mark in a high-scaling subject. (Correct answer)
- Scaling will be waived for this student because they are an outlier.
Correct answer: A high raw mark in a lower-scaling subject can still contribute more to their ATAR than a poor mark in a high-scaling subject.
It's a common misconception that choosing a high-scaling subject guarantees a better ATAR. A student's performance relative to the rest of the cohort in that subject is crucial. Achieving a very high raw score in a subject that tends to scale down can still result in a strong scaled score, which may be more beneficial to the ATAR calculation than a mediocre or low score in a subject that typically scales up.
Question 3: Which process is used to adjust the internal assessment marks from a school to align them with the standards of the external state-wide examination?
- Aggregation
- Percentile Ranking
- Scaling
- Moderation (Correct answer)
Correct answer: Moderation
Moderation is the process that adjusts a school's internal assessment marks to make them comparable with marks from other schools. It uses the school cohort's performance on the common external exam as a benchmark to ensure fairness, accounting for variations in marking standards between schools.
Question 4: In the context of ATAR, how is the 'strength of the competition' in a particular subject primarily determined for scaling purposes?
- By the ATARs achieved by students who took the subject in previous years.
- By the overall academic performance of the students in that subject across all their other subjects. (Correct answer)
- By the average number of hours students report studying for that subject.
- By university feedback on which subjects best prepare students for tertiary studies.
Correct answer: By the overall academic performance of the students in that subject across all their other subjects.
Scaling is determined by the academic achievement of the entire cohort of students who undertook that course. If students who take a particular subject (e.g., Chemistry) tend to perform very well across all their other subjects, that subject (Chemistry) is considered to have a strong, competitive cohort, and this will be reflected in how it is scaled.
Question 5: A student is deciding between two subjects for their final year. Subject A historically scales very well, but the student finds it extremely difficult and uninteresting. Subject B scales moderately but aligns with the student's strengths and interests. What is the most strategic advice for this student to maximise their ATAR?
- Choose Subject A, as the high scaling will compensate for a potentially lower raw mark.
- Choose Subject B, as they are more likely to achieve a higher raw mark, which is crucial for a good scaled score. (Correct answer)
- Choose both subjects and drop the one with the lower mark after the first assessment period.
- The choice is irrelevant as scaling ensures all outcomes are equalised.
Correct answer: Choose Subject B, as they are more likely to achieve a higher raw mark, which is crucial for a good scaled score.
The best strategy for maximising ATAR is to choose subjects where the student has the potential to perform at a high level. A high raw mark in a subject a student enjoys and is good at will generally lead to a better scaled score than a low or average mark in a high-scaling subject they struggle with. Students are advised to pick subjects they enjoy and are good at over subjects they think will scale well.
Question 6: What is the key difference between moderation and scaling in the ATAR process?
- Moderation compares students within the same school, while scaling compares students across different states.
- Moderation adjusts internal school assessments for fairness across schools, while scaling adjusts subject scores for fairness across different subjects. (Correct answer)
- Moderation is applied to exam marks, while scaling is applied to internal assessment marks.
- Moderation is done by the school, while scaling is done by the national Tertiary Admissions Centre.
Correct answer: Moderation adjusts internal school assessments for fairness across schools, while scaling adjusts subject scores for fairness across different subjects.
Moderation ensures fairness by adjusting internal school assessment marks to align with the standards of the external exam, making marks comparable between different schools. Scaling, on the other hand, is the subsequent process that adjusts these moderated marks to account for the differences in difficulty and cohort strength between different subjects, allowing for a fair comparison of performance across all subjects.
