QCE internal assessment, explained

Your ISMG rewards what your response actually shows, not what it claims.

Every IA1, IA2 and IA3 is marked against an Instrument-Specific Marking Guide QCAA builds into the syllabus for that exact task. Here's how that document is structured and what its top level actually asks for.

This guide is about the ISMG itself. For how IA1, IA2, IA3 and the external exam combine into your subject result, see how QCE internal assessment works — that guide covers the weighting, this one doesn't repeat it.

What an ISMG actually is

"Instrument-specific" means exactly that: every assessment instrument, IA1, IA2, IA3, has its own ISMG, built for that task, not a generic subject rubric reused across the year. QCAA's syllabus for each subject provides the ISMG for every summative internal assessment instrument. It describes the characteristics evident in student responses and groups the syllabus's assessment objectives into a handful of criteria.

Each criterion is a ladder: a set of mark ranges, commonly something like 6–7, 4–5, 2–3, 1 and 0, with each range carrying its own written, dot-point descriptors. The exact ranges and the number of criteria differ by subject and by instrument, so treat this as the shape of the document rather than a fixed table that applies to every IA.

How a marker actually uses it

A marker doesn't tick off every bullet point in a mark range and add them up. They read the response against each criterion's descriptors and place it in whichever mark range's characteristics describe the response best overall. Missing one line of a top-range descriptor doesn't automatically drop a response a full range, and hitting a single top-range line in an otherwise weaker response doesn't lift it either. It's a best-fit judgement, made against the whole of what's on the page for that criterion.

That best-fit judgement is also what QCAA's confirmation process checks. A sample of responses from every subject in every school is reviewed by QCAA-endorsed assessors to confirm the ISMG was applied consistently, which is the mechanism that keeps one school's Band A from meaning something different to another school's.

Two ways marks are commonly lost

Going outside the word-length range

QCAA's own policy is specific here: a school cannot penalise a response for missing the length conditions by arbitrarily reducing its mark. What it does instead is require schools to have strategies for managing length before submission, and for marking a response that runs over. In practice that means a marker isn't obliged to keep reading and crediting content past the stated limit, so going over the range risks losing marks by omission, not by a stated penalty.

A claim the response doesn't actually demonstrate

Because the ISMG describes "characteristics evident in student responses", a sentence that states a judgement without showing the working behind it isn't evidence of the criterion, it's an assertion of it. The two read very differently against a descriptor that's asking for analysis or evaluation to be demonstrated, not declared.

Turning a descriptor into a checklist

An illustration of the method, not a real QCAA descriptor

Say a top-range descriptor reads: "discerning analysis of how language choices shape meaning, supported by well-chosen evidence." Broken into a checklist, that's three separate things a marker is looking for: (1) analysis, not just identification, of a language choice; (2) a stated link between that choice and the meaning it shapes; (3) evidence, a specific quote or example, attached to the claim rather than sitting nearby it.

A response can name the right language feature and still miss the range if step two or three is missing, because the descriptor is asking for all three, not one.

Check your draft against the descriptor, not the vibe

StudyDesign AI marks a practice response against the kind of standards your IA is graded on, and shows you which one is unaddressed. It will not write the assessed task for you.
