2019 Scaling Report - VTAC scaled study score means and standard deviations

Sep 5, 2026

Uploaded by Dozel

2019 Scaling Report explains how VCAA study scores are scaled to compute scaled aggregates and Australian Tertiary Admission Ranks (ATARs). It defines the 2019 scaling population as candidates with at least one VCAA study score in 2019, at least four in total, and at least one English-related study score, excluding small studies and those who already have an ATAR. The report provides scaled means and standard deviations for 2019, mapping VTAC scaled study scores to original study scores (rounded).

2019 Scaling Report

Scaling population and purpose

Scaled means, standard deviations, and score mapping

2019 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 2019 scaling population if, excluding small studies, they have obtained at least one VCAA study score in 2019, at least four in total , at least one in an English study [English, English (EAL), 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 2019. The following table gives the 2019 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 the scaling process in 2019?

VCAA study scores are scaled to calculate scaled aggregates and Australian Tertiary Admission Ranks (ATARs). VTAC scaled study scores are used during formal aggregation.

Who belongs to the 2019 scaling population?

Candidates are included if, excluding small studies, they have at least one VCAA study score in 2019, at least four in total, at least one English study score, and they do not already have an ATAR.

What information does the report provide in the table?

The table lists 2019 scaled means and standard deviations and the VTAC scaled study scores (rounded to the nearest integer) corresponding to study scores such as 20, 25, 30, 35, 40, 45, and 50.
