VCE Study Score: How It Is Calculated (VCAA)

A VCE study score is a number from 0 to 50 that shows how you performed in one study compared with every other student who took that study in the same year. VCAA calculates it from your three graded assessments in Units 3 and 4, converts the result to a scale with a mean of 30, and most scores land between 23 and 37.

This guide describes the 2026 VCE Administrative Handbook, which applies to students completing Units 3 and 4 in 2026. Study scores are produced only from Units 3 and 4 graded assessments. For past exams and marked questions in each study, start from VCE past exams (VCAA).

What is a VCE study score?

A study score is a ranking turned into a score. It is not a percentage and it is not a raw mark. VCAA calculates it from your final scores for school-assessed coursework (SACs), school-assessed tasks (SATs), externally assessed tasks and examinations, whichever your study uses.

Because the score is relative, the same exam mark can produce different study scores in different years or different studies.

Your study score is not your ATAR either. VTAC scales each study score before it builds your ATAR, and that scaled score is a separate number (see the end of this guide).

What are the graded assessments behind a study score?

Every VCE study except the VCE Vocational Major studies has three graded assessments (GAs) in its Units 3 and 4 sequence, and at least one of them is external. The study's contribution percentages say how much each counts. VCAA lists the full table for every study in its assessment summary, so check your own study there.

The split varies a lot, so the fair summary is that in most studies the exam is worth about half and in some it is worth more or less. A few examples from VCAA's 2026 summary:

Where a study has examinations, their combined share runs from 15% (Music Inquiry) to 75% (Dance), and Extended Investigation has no examination at all (its external assessment is the Critical Thinking Test, worth 60%). So "the exam is worth 50%" is true for some studies and wrong for others.

Each graded assessment is also reported as a grade, from A+ to E, plus UG (ungraded, meaning the score was too low to assign a grade) and NA (not assessed, meaning a school-based assessment was not submitted or the exam was not sat). VCAA sets the minimum score for each grade after statistical moderation for school-based assessments, and at the end of marking for external ones. The letter grades belong to the graded assessments. The study score itself has no letter.

How is the VCE study score calculated?

VCAA describes four steps in its score aggregation page.

1. Standardisation. Each graded assessment's final score is standardised: the state mean for that assessment is subtracted from your score, and the result is divided by the state standard deviation.
2. Weighting. Each standardised score is multiplied by that assessment's percentage contribution to the study score. For English that is 0.25 for Unit 3 coursework, 0.25 for Unit 4 coursework and 0.50 for the exam.
3. Ranking. The weighted scores are added up (up to three in a VCE study). All students in the study are ranked by their total, and students with the same total get the group's highest rank.
4. Normalising and scaling. The ranks are normalised with an inverse normal function, then converted to a scale with a mean of 30 and a standard deviation of 7, truncated at 0 and 50. VCAA adds that further adjustments are made for studies with small numbers of students, and the score aggregation page does not say what they are.

The step that matters most is the ranking. Two students with the same weighted total get the same score, and a higher score needs a higher position in the state, not a higher raw mark.

What does statistical moderation do to my SAC scores?

Schools set different tasks, so SAC scores from different schools cannot be compared directly. Statistical moderation fixes that before step 1 above. VCAA aligns the distribution of each school's SAC scores in a study with the distribution of the external scores for the same group of students. The external score is built from exam results, in common tasks with common assessors. In studies with two external assessments, both are used.

Three things follow from VCAA's wording:

• Your rank inside your school is kept. VCAA says moderation does not change the relative performance of students within the moderation group.
• The numbers can move. Schools tell you your initial SAC scores, and VCAA's handbook requires teachers to warn students that those scores may change after moderation. If your school's cohort does well on the exam, its SAC scores are aligned with that stronger distribution.
• Each school is one group. For a VCE study the moderation group is the cohort of students at your school taking that study, or the combined cohort if schools combine for assessment. A school's assessments in a study are treated as a single group, not as separate classes.

The GAT also has a part. In a few studies where it improves moderation, GAT results are used as part of the external score, but VCAA says exam scores remain the primary reference. The handbook does not name those studies. The GAT is also one of the inputs used to calculate a Derived Examination Score, covered below.

What is an average or good VCE study score?

The average is 30. VCAA converts every study to a mean of 30 and a standard deviation of 7, and says most study scores fall between 23 and 37. VTAC confirms that each study arrives with an average of 30.

VCAA's handbook also gives an approximate distribution:

The maximum is 50. A study score below 20 is reported to the student as "<20".

Whether a score is good depends on what you need it for. Your ATAR is not calculated from raw study scores, so the same 40 in two different studies can contribute different amounts. See the section below.

Unscored VCE: which studies and students get no study score?

A study score is not produced in these cases, according to the 2026 handbook:

• VCE Vocational Major studies. They have no scored assessment, give no study score and cannot count toward an ATAR.
• A study done without scored assessment. A student can complete VCE units, and still be assessed for satisfactory completion and levels of achievement, without a score being provided to VCAA. In that case all graded assessments are entered as NA and no study score is calculated.
• Fewer than two graded assessments. A student needs 2 or more graded assessments in the study and an S for both Units 3 and 4 in the same academic year. A student with Interrupted Studies status can meet this over two academic years, using their best result for each graded assessment across those years.
• Study score unavailable. If more than one graded assessment is NA, or Units 3 and 4 were not satisfactorily completed, the result is reported as UN.

Students with interstate credit at Units 3 and 4 level get a study score only if they have credit for Unit 3, receive an S for Unit 4 in a similar VCE study and attempt at least two graded assessments in the VCE study.

Scored VCE VET studies work the same way with two graded assessments (the SAC and a VCAA exam) instead of three.

What if I am sick or miss part of the exam?

Students, not schools, are responsible for applying for a Derived Examination Score (DES), which is intended for a student who is ill or affected by other personal circumstances at the time of an exam. VCAA calculates it statistically from your moderated school-based assessments, GAT component scores, any other external assessment scores and the indicative grades your school provided. If the highest predictor is greater than your achieved exam score, that predictor is used, so you are awarded the higher of the two. The handbook says the two school-based scores contribute most to the predictors.

A student with three exams on one day does not need to apply: they automatically receive a DES for the third exam, provided they attend all three, attempt the questions to the best of their ability, have completed the course of study and have a result for at least one other graded assessment in that study. VCAA then awards the higher of the actual exam score and the DES. Ask your VCE coordinator how the application works at your school. The VCE exam timetable lists the dates.

How does a study score become an ATAR?

VTAC does this, not VCAA. VTAC receives each study already standardised to an average of 30, then scales it to account for the level of competition in that study, and the result is called a scaled study score. It is a score from 0.00 to 55.00.

To qualify for an ATAR you need study scores in at least four permissible Unit 3 and 4 studies, including one from the English group. The aggregate is your scaled score in an English-group study plus your next three highest permissible scaled scores (the primary four), plus up to two increments, normally 10% of a fifth and sixth scaled score. English is always in the primary four.

Scaling reflects the competition in a study. VTAC says it is not because some studies are inherently harder or easier, and that a scaled-down score in a study you did well in will most likely beat a scaled-up score in one you did badly in.

What you can control

• Your SAC rank matters more than the number. Moderation keeps your rank in your school, so consistent performance across the year protects the thing that is kept.
• The exam does double duty. It is a graded assessment in its own right, and it is the benchmark that your school's SAC scores are aligned to.
• Know your study's weightings. In Methods and Specialist the two exams together are worth 60% and the SAC 40%. In Biology the Unit 4 SAC is worth more than the Unit 3 SAC. Check your study in VCAA's assessment summary before you plan your year.
• Past exams show what is asked. Work through them with the examiner's reports. Start from your study on VCE past exams (VCAA), then use how to prepare for VCE exams to plan backwards from your dates.
