2025 Scaling Report - VCAA Study Scores and VTAC Scaling

Sep 5, 2026

2025 Scaling Report explains how VCAA provides study scores (relative positions) that are scaled to calculate scaled aggregates and Australian Tertiary Admission Ranks (ATARs). It defines the 2025 scaling population and specifies eligibility conditions for candidates with VCAA study scores, including English-related studies, while excluding applicants who already have an ATAR. The report presents 2025 scaled means and standard deviations plus VTAC scaled study-score values for selected marks across numerous subjects and codes.

2025 Scaling Report VCAA provides VTAC with study scores (relative positions) . These study scores are scaled in order to calculate scaled aggregates and Australian Tertiary Admission Ranks (ATARs) . Candidates are in the 2025 scaling population if, excluding small studies, they have obtained at least one VCAA study score in 2025, at least four in total, at least one in an English study [English, English as an Additional Language, English Language or Literature], but do not already have an ATAR. The scaling population is therefore a subset of the entire population. The means and standard deviations below pertain to the scaling population in 2025. The following table gives the 2025 scaled means and standard deviations as well as the VTAC scaled study scores (rounded to the nearest integer) corresponding to the study scores of 20, 25, 30, 35, 40, 45 and 50. The formal aggregation process uses VTAC scaled study scores to two decimal places, but the following information gives an indication of how scaling adjusts scores in the various studies.

FAQs

What is the purpose of scaling in calculating ATARs?

VCAA study scores are scaled to compute scaled aggregates and Australian Tertiary Admission Ranks (ATARs). This adjusts relative positions for use in the formal ranking process.

Who is included in the 2025 scaling population?

Candidates are included when, after excluding small studies, they have at least one VCAA study score in 2025, at least four in total, at least one in an English study, and they do not already have an ATAR.

What information do the tables provide for 2025 scaling?

The tables give 2025 scaled means and standard deviations, and VTAC scaled study scores (rounded to the nearest integer) corresponding to study score values of 20, 25, 30, 35, 40, 45, and 50 for each subject code.
