What Is a Derived Examination Score (DES)?
A Derived Examination Score (DES) is a VCAA special-provision safety net. If you are significantly affected by illness, injury or personal trauma at the time of a VCE exam (or cannot sit it), VCAA can calculate a “derived” score for that exam from your other results. To be eligible you must have completed the study and have at least one other graded assessment result in it. VCAA then uses the higher of your DES or your actual exam score – so applying can only help, never hurt, your result. (Source: VCAA; you apply through your school.)
Key takeaways
- A DES is a VCAA safety net if illness, injury or trauma affects you at exam time.
- VCAA uses the higher of your DES or your actual exam score – so it can only help.
- It is derived from your GAT, coursework, other exam scores and the school’s indicative grade.
- Apply through your school; it is not available for the GAT or certain externally-assessed tasks.
What a DES actually is
A DES is a score VCAA derives for an exam you could not do justice to because of illness, injury or trauma. It is part of VCAA’s Special Provision – not an exemption, but a fair estimate of your ability based on the work you have already shown.
Who’s eligible?
To be eligible for a DES you must: (1) have completed the course of study for that exam; (2) have a result for at least one other graded assessment in the same study; and (3) be significantly affected by the onset of illness, an injury, or personal trauma at the time of the exam. You apply through your school, usually with documentation.
How is a DES calculated?
VCAA combines your GAT component scores, your moderated coursework and SAC scores in that study, any other exam scores in the study, and your school’s indicative grade. This is one reason the GAT matters even though it is not scored like a subject.
Does a DES lower my score?
No. VCAA uses whichever is higher – the DES or your actual exam mark. So a DES can only protect or lift your result, never reduce it.
What a DES doesn’t cover
A DES is not available for the GAT itself, or for certain externally-assessed tasks (Music Composition, Music Inquiry, and the Extended Investigation written report). For how exams and SACs fit together, see VCE exam structure & SACs explained.
