What is official, and what is estimated?
VTAC and VCAA publish historical results. VCE Pilot uses these as inputs, but is an independent site. It is not affiliated with, endorsed by or operated by either authority. Final 2026 scaling, grade boundaries and ATAR conversion tables are not available yet.
ATAR calculations
The calculator uses the full 2025 aggregate-to-ATAR table, including every published 0.05 ATAR band from 30.00 to 99.95, and the equivalent 2024 table. It rounds the aggregate to two decimal places before looking up a band. Results below the lowest published band are displayed as “Below 30”.
Raw score scaling uses the seven published anchors at 20, 25, 30, 35, 40, 45 and 50 from the 2025 scaling report. Scores between anchors use linear interpolation. The anchors themselves are rounded by VTAC, so this cannot reproduce official scaling to two decimal places. We do not invent values below raw 20: enter an official scaled score for these cases.
We search the permissible combinations for the highest aggregate, requiring the highest English study in the primary four, no equivalent studies, no more than two results from a study area group in the primary four, and no more than three in the total. Up to two extra studies contribute 10% each. Small language studies use VTAC’s published “All small LOTEs” row. Language adjustments are already included and are not added again.
The calculator supports scored VCE and the scored VET subjects in the historical scaling report. It does not calculate non-scored VET, VE3, higher education increments, interstate credit, interrupted studies, eligibility for the VCE or course-specific selection adjustments. Check these cases with your school and VTAC’s current rules. A 2024 comparison is unavailable when a subject has no comparable historical entry. Previously completed subjects keep the scaling from their actual year; use official scaled-score mode rather than re-scaling them.
Study score scenarios
For 50 supported studies, we use VCAA’s 2025 assessment distributions and the 2026 assessment contributions. Historical GA labels and structures are shown so that students can check whether a revised study design is comparable.
Each assessment percentage is converted to the reported assessment scale. We calculate z = (mark − historical mean) / historical standard deviation, then a weighted sum of the three z scores. VCAA also standardises and weights assessment scores, but its final step ranks every student’s weighted total before normalisation. Public data does not provide the joint student-level distribution needed to reproduce that step.
Our model assumes a normal weighted-total distribution and a common correlation ρ between assessment scores. Its standard deviation is √[Σw² + ρ(1 − Σw²)]. The central scenario uses ρ = 0.6; sensitivity endpoints use ρ = 0.3 and 0.9. We display 30 + 7 × weighted z / assumed standard deviation, clipped to 0–50. The span is an assumption sensitivity range, not a confidence interval, a validated forecast or an official study score. The model has not been fitted or validated against individual study score outcomes.
Coursework inputs must be projected moderated marks, not untreated school percentages. If you only know school marks, the calculator cannot know their final moderated values. The coursework sensitivity slider is a user-selected hypothetical percentage-point change. It does not perform statistical moderation. Using 2026 weights with 2025 results assumes the assessment structure is comparable; always check current study designs.
Grade labels use the historical score band containing the nearest whole reported mark. Percentile intervals use actual counts below and within that whole grade band, among assessed students. We do not pretend to know where a mark sits within the band. These intervals describe one assessment; they are not final study score ranks. Some exam reports use the sum of two examiners’ marks, so their maximum can be twice the paper’s printed maximum. Percentages remain comparable on either scale.
School and cohort context
The school explorer contains 607 records from the 2025 Senior Secondary Completion and Achievement Information, accurate as at 6 December 2025 according to the source workbook. Records can represent campuses or providers, and enrolment counts include students taking at least one Unit 3–4 VCE, VM or VET study; they are not simply Year 12 class sizes.
Median study score and the percentage of study scores of 40 or over describe school-wide results across studies. They do not provide subject-specific cohort distributions or individual student data. We never convert them into an individual score boost. “I/D”, missing values and small-school suppression are preserved. The cohort rank helper reports position within the entered cohort only. It does not map that rank to a statewide percentile.
