CER Paragraph Examples for NAPLAN Writing: Year 3, 5, 7 & 9

One Structure, Four Levels of Sophistication

CER (Claim, Evidence, Reasoning) can provide the same three-part shape at every year level while vocabulary precision, sentence variety, and the depth of the Evidence and Reasoning sentences develop. The independently authored examples below illustrate one possible progression across the NAPLAN writing year levels (3, 5, 7 and 9). CER is a classroom planning framework, not a NAPLAN-prescribed structure or year-level standard. All four examples use the same familiar prompt — school uniforms — so their writing choices are easy to compare side by side. For the full structure breakdown, see the CER method guide; for a side-by-side with the other major framework, see CER vs TEEL.

Year 3 Example

Prompt: Should students have to wear a school uniform?

Claim: Students should wear a school uniform.

Evidence: For example, when everyone wears the same clothes, there is less arguing about what to wear each morning.

Reasoning: This shows that uniforms make mornings easier for students and families.

In this Year 3 teaching example, the writer uses a short, clear claim, one simple piece of evidence, and a reasoning sentence that restates the point plainly. Simple connectives such as "for example" and "this shows" keep the argument easy to follow. These are illustrative choices, not official year-level requirements.

Year 5 Example

Prompt: Should students have to wear a school uniform?

Claim: Wearing a school uniform helps students focus on learning instead of on clothes.

Evidence: For example, students who wear the same uniform do not need to compare outfits or worry about keeping up with changing trends.

Reasoning: This proves that uniforms remove a daily distraction, giving students more energy to spend on their schoolwork.

In this Year 5 teaching example, sentences are longer and more varied, the Evidence sentence gives a concrete scenario, and the Reasoning sentence explains the effect rather than simply repeating the claim. This is one possible writing choice, not an official year-level requirement.

Year 7 Example

Prompt: Should schools require students to wear a uniform?

Claim: School uniforms should remain compulsory because they reduce social pressure around appearance.

Evidence: For example, in a school without a uniform policy, a student might be judged on the brand of their clothing rather than on their achievements.

Reasoning: This demonstrates that a uniform policy shifts attention away from appearance and towards a more equal school environment, although some students argue it limits self-expression.

In this Year 7 teaching example, the Reasoning sentence acknowledges a counter-argument ("although some students argue...") before restating the position — one technique a writer can use to strengthen a persuasive paragraph.

Year 9 Example

Prompt: Should schools require students to wear a uniform?

Claim: A compulsory uniform policy is a reasonable measure for reducing socioeconomic visibility among students, not an unnecessary restriction on individuality.

Evidence: For example, removing visible differences in clothing brand or cost limits one obvious way students might otherwise be judged or excluded by peers.

Reasoning: Critics who frame uniforms as suppressing self-expression overlook that the policy targets a narrow, comparison-driven source of social pressure, leaving other forms of individuality — conversation, achievement, personality — untouched, which makes the restriction proportionate rather than punitive.

In this Year 9 teaching example, vocabulary is more precise ("proportionate rather than punitive"), the Evidence sentence names a specific mechanism, and the Reasoning sentence directly rebuts a counter-argument. These are illustrative choices, not prescribed NAPLAN expectations.

How These Examples Develop Across Year Levels

Comparing these four independently authored examples side by side, three writing choices develop while the three-part teaching framework stays consistent:

• Vocabulary precision — from "makes mornings easier" (Year 3) to "proportionate rather than punitive" (Year 9).
• Evidence depth — from a single concrete example to evidence that names a specific mechanism.
• Reasoning sophistication — from a simple restatement to a sentence that directly answers a counter-argument.

Practise Your Own CER Paragraph

The fastest way to internalise the pattern is to write one CER paragraph on a familiar topic and get feedback on it. Try the interactive CER planner to build a paragraph step by step, or write a full response with our free NAPLAN writing prompts and receive AI-generated practice feedback based on our independently authored explanations of the publicly documented NAPLAN marking criteria. The feedback is not an official NAPLAN score, may not replicate official marking, and should be reviewed with a parent or teacher.
