Writing is the only ASET section where students have full creative control — and the most commonly under-prepared. Understanding the 24-point rubric before writing a single practice response can add 4–6 marks immediately.

What the Writing Section Tests

The Written Expression section gives students one prompt and 25 minutes to produce a response. Two trained markers independently score it using the 24-point rubric. The combined score is standardised and added to the TSS.

Unlike the other three sections, writing is the only place where preparation produces qualitatively different responses — not just faster or more accurate ones. A student who understands the four criteria and plans deliberately will outperform a more naturally gifted writer who starts immediately without structure.

The 24-Point Rubric — Criterion by Criterion

Each criterion is scored 0–6 by two markers. Here is exactly what markers look for at each level.

1

Ideas & Content /6

The originality, relevance, and development of the central idea. Markers look for a clear focus, specific detail, and an individual voice — not a generic retelling of the prompt.

Low score (1–3)

Predictable ideas, thin development, little specific detail. The piece reads like a formula response.

High score (5–6)

Surprising angle or insight, vivid specific detail, clear individual perspective. The reader wants to know what happens next or what the writer thinks.

Strategy: Spend the first 2 minutes of planning identifying what makes your angle different. "A student wins a prize" is forgettable. "A student wins a prize they do not deserve and must decide what to do" creates immediate tension.

2

Text Structure & Organisation /6

How well the piece is organised: opening, paragraphing, transitions, and conclusion. Each paragraph should have a clear purpose. The ending should feel deliberate, not abrupt.

Low score (1–3)

No clear opening hook. Paragraphs run together without clear purpose. Ending is rushed or absent.

High score (5–6)

Strong opening that creates immediate interest. Clear paragraphing with each para advancing the piece. Satisfying ending that connects back to the opening or resolves the central tension.

Strategy: Plan your ending before you write the opening. Knowing where you are going makes the structure almost write itself. A common mistake is writing until time runs out — the last paragraph is rushed and drags down the structure score.

3

Vocabulary & Language Devices /6

The quality and variety of word choice. Markers reward precise, evocative language and penalise vague, overused vocabulary. Simple figurative language (metaphor, simile, personification) adds marks when used deliberately.

Low score (1–3)

Common, predictable words ("nice", "good", "went"). Vague adjectives. Little figurative language.

High score (5–6)

Precise verbs and nouns instead of adjectives. Intentional figurative language. Varied sentence lengths that create rhythm. Vocabulary that is ambitious but appropriate to the context.

Strategy: Build a vocabulary bank before the exam. Each week, learn 5 strong verbs, 5 precise adjectives, and 2 metaphors. During planning, write down 3 powerful words you intend to use — then use them.

4

Conventions /6

Spelling, punctuation, grammar, and sentence structure. This criterion rewards consistency and control, not perfection. One or two errors in an otherwise controlled piece still score well.

Low score (1–3)

Frequent spelling errors on common words. Sentence fragments or run-ons throughout. Missing punctuation that makes meaning unclear.

High score (5–6)

Correct spelling of all but the most complex words. Full sentences with varied structure. Purposeful punctuation: commas, dashes, and semi-colons used correctly. One or two proofread errors tolerated.

Strategy: Reserve the last 2 minutes for proofreading — specifically target: capital letters at sentence starts, apostrophes in contractions, and full stops. These are the three highest-frequency, easiest-to-fix errors.

The 10-Minute Planning Method

Students who spend 8–10 minutes planning and 15 minutes writing consistently outscore students who start writing immediately. Planning eliminates the two biggest structural errors: weak openings and abrupt endings.

0–1 min

Read and decode the prompt

Read the prompt twice. Identify: Is this narrative (tell a story), persuasive (argue a point), or descriptive? What is the exact scenario or topic? Underline the key instruction word.

1–3 min

Generate ideas — quantity first

Write 3–5 quick ideas without judging them. The first idea is usually the most predictable. The third or fourth is often the best. Do not start writing until you have chosen your angle.

3–6 min

Plan the structure

Sketch: Opening (hook) → 2–3 body paragraphs (what each one does) → Ending (how it resolves or lands). For persuasive: Claim → 2 arguments + evidence → Counter + rebuttal → Strong conclusion.

6–8 min

Choose vocabulary

Write down 3 strong verbs, 2 precise adjectives, and 1 figurative device you will use. This takes 90 seconds and ensures your vocabulary criterion is not left to chance.

8–10 min

Write your opening sentence

Before writing the full piece, write and re-write the opening sentence until it is strong. A great first sentence makes the rest of the piece easier to write and impresses markers immediately.

Prompt Types & How to Approach Each

1

Narrative Most common

"Write a story about a discovery that changes everything."

"Write about a time you had to make a difficult choice."

"Continue this story: The door opened onto something no one expected..."

Focus on a single event with a clear beginning, turning point, and resolution. Do not try to cover too much time. A 15-minute narrative set in one scene is more effective than a years-long epic.

2

Persuasive Common

"Should schools ban mobile phones?"

"Write a speech convincing your class to take action on climate change."

"Argue for or against: homework should be abolished."

Take a clear, specific position in your first paragraph — do not sit on the fence. Use evidence (statistics, examples, expert opinion) to support each argument. Address the counterargument briefly and dismiss it.

3

Imaginative / Hybrid Occasional

"Imagine you can visit any time in history. Write about your experience."

"You are the last person on Earth. Describe your day."

"Write from the perspective of an object in your classroom."

These prompts reward originality most heavily. The unusual angle scores better than the obvious one. Ground your imaginative piece with specific sensory detail — it makes even far-fetched scenarios feel real and convincing.

Frequently Asked Questions

How is writing marked in the ASET?
Writing is marked against a 24-point rubric with four criteria of 6 marks each: Ideas & Content, Text Structure & Organisation, Vocabulary & Language Devices, and Conventions. Two trained markers independently score each paper. The scores are combined for the final Writing TSS section score.
What score out of 24 is considered good for WA GATE?
A score of 18–20 out of 24 is competitive for most GATE programs. A score of 21–24 is exceptional and correlates strongly with Perth Modern School-level TSS totals. Most students without targeted preparation score 12–15. A well-planned, proofread response typically adds 3–5 marks over an unprepared one.
How long should the ASET writing response be?
There is no prescribed length, but markers note that stronger responses tend to be 3–5 well-developed paragraphs (approximately 300–450 words). A short, polished response scores better than a long, poorly organised one. Quality over quantity is the right mindset.
What type of writing prompt appears in ASET?
ASET writing prompts are most commonly narrative (tell a story) or persuasive (argue a position). Imaginative prompts occasionally appear. Descriptive-only prompts are rare. Students should practise all three types but prioritise narrative — it appears most frequently and is most open-ended, which plays to individual strengths.
Does the ASET writing section give you planning time?
Yes. The Writing section is 25 minutes in total, with a recommended planning time of approximately 10 minutes (some sources cite 5 minutes). Using the planning time strategically — rather than starting to write immediately — consistently produces higher-scoring responses. The writing time is approximately 15 minutes.
