How NAPLAN writing is actually marked

Most parents picture writing being marked the way a teacher marks a school essay: read it, form an impression, put a number at the bottom. NAPLAN does not work like that, and once you know how it does work, a lot of advice about "writing more" stops making sense.

The score is a sum of separate judgements

A NAPLAN writing task is assessed against a set of separate criteria, each scored on its own scale, and the total is the sum. A piece can score well on ideas and poorly on paragraphing. Another can be technically tidy across spelling and punctuation and still lose most of its marks on structure. The two pieces can end up with the same total by completely different routes.

The criteria cover, broadly:

• Audience and text structure: whether the piece does the job the prompt asked for, and whether it is built like the kind of text it claims to be.
• Ideas: what is actually being said, and how well it is developed.
• Character and setting (narrative) or persuasive devices (persuasive): the craft specific to the text type.
• Vocabulary: precision and range, not length.
• Cohesion: whether the reader can follow it without going back.
• Paragraphing: whether the piece is organised into units that mean something.
• Sentence structure, punctuation, and spelling: the mechanics.

ACARA publishes the marking guide and the criteria it uses. If you want the authoritative version rather than a summary, go there: the official NAPLAN site.

Why that changes how you practise

Two things follow from a criterion-based score, and both are practical.

A single number tells your child nothing they can act on. "You got 28" does not point at anything. "You lost marks on paragraphing and cohesion, and your spelling was fine" points at exactly one thing to do next week. If your child comes home from a practice piece with a total and nothing else, the practice has told them how they did but not what to change.

Weak criteria are worth more than strong ones. A child already scoring near the top on spelling has very little left to gain there, however much time they spend on spelling lists. The same hour spent on the criterion they are losing most marks on is worth several times more. This is unintuitive, because spelling practice feels productive and structure practice feels vague.

What this looks like in practice

The useful drill is small and specific. If paragraphing is the weak criterion, the exercise is not "write another whole piece": it is taking a piece already written and breaking it into paragraphs that each carry one idea. If cohesion is the weak one, it is reading the piece aloud and marking every place the reader would have to go back.

Full pieces still matter, because the real task is a full piece under time. But a full piece a week that gets a total and no breakdown is mostly practice at being timed. The breakdown is where the improvement comes from.

The one caveat worth stating

Any practice result, here or anywhere else, is an estimate from that sitting alone. It is not a prediction of a real NAPLAN outcome, and nobody can give you one. What a practice result is genuinely good for is the same thing a coach uses a training run for: it shows what to work on next.
