QCE external assessment: how the ISMG marks your response
11 July 2026 · 6 min read · Mark That Paper

If you're sitting QCE assessment, there's one document worth more than any study guide: the ISMG. It stands for Instrument-Specific Marking Guide, and it's the exact grid a marker uses to score your response. Students who read it closely aren't working harder than everyone else. They're just aiming at the actual target instead of an imagined one.
What the ISMG is
The QCAA builds an ISMG for each assessment instrument. It lays out the criteria being assessed, and for each criterion it describes the characteristics of work at different quality levels, tied to mark ranges. So a criterion isn't just "analysis" — it's analysis described at a top range, a middle range, and a lower range, each with its own language. Your marker reads your response, matches it to the characteristics that best fit, and lands in the corresponding range.
That structure is the whole game. Marks are awarded per criterion, and within each criterion by matching your work to described characteristics — not by an overall vibe. It's the same logic that governs criterion-based marking everywhere: the descriptors name what earns the marks.
How to read a mark range
Take any criterion on the ISMG and read across its ranges. The difference between the top and the middle is almost always a shift in a few decisive words:
- "Discerning" → "effective" → "adequate": the quality and precision of your judgement.
- "Analyses" → "describes": whether you explain how something works or just report that it does.
- "Sustained" → "variable": whether a quality holds across the whole response or flickers in and out.
The ISMG isn't a checklist to tick. It's the sentence your marker will choose about your work — so write the response that makes the top sentence the honest one.
Turn characteristics into questions
The most useful thing you can do with an ISMG is convert each top-range characteristic into a question you ask of your own draft. "Is my analysis discerning, or just present? Show me where." If you can't point to the line, that's the line to rewrite. This is exactly the habit that pays off later at university, where explicit marking criteria only get more demanding.
Practise the loop, not the page count
Because the ISMG marks per criterion, useful practice returns per-criterion information— not one number, but a read of which criterion sits in which range and why. A single overall grade can't tell you what to fix. A criterion-by-criterion read tells you exactly what the next draft is for.
That's what Mark gives QCE essay feedbackto do: upload the ISMG and your draft, and he returns a mark per criterion with the quoted line as evidence — the same range judgement a QCAA marker makes, on your own response, before it's marked for real. Find the weakest criterion, fix it, mark again. The loop is the method.
See your response against the ISMG — a mark per criterion, with the lines that put you in each mark range.
