Struggling to write a high-scoring opinion essay?
I’m assuming you’re stuck trying to figure out if you should discuss both sides or just your own (and losing marks in Task Response). This guide fixes that - step by step.
Part of the IELTS Writing series. For the complete overview of all five Task 2 question types, see the IELTS Preparation Guide or IELTS Writing Task Types.
Key Takeaways
- IELTS opinion essay = "To what extent do you agree or disagree?" - give ONE clear position.
- Introduction: paraphrase prompt + thesis in 2-3 sentences (40-50 words).
- Body: 2 paragraphs, each with 1 main idea + evidence + example (5-8 sentences each).
- Conclusion: restate position + summarise main points (2-3 sentences, no new ideas).
- Target Band 7+: write 260-290 words; Band 8+: aim for 280-310 with complex structures.
- Most common mistake: giving a balanced argument instead of a clear opinion (drops Task Achievement).
How do you write an IELTS opinion essay?
An IELTS opinion essay (agree/disagree) requires you to state one clear position in the introduction and maintain it throughout every paragraph. The structure is: Introduction (paraphrase + thesis) → Body Paragraph 1 → Body Paragraph 2 → Conclusion (restate position + summary). Never discuss both sides equally - examiners penalise unclear or shifting opinions.
- Prompt trigger: "To what extent do you agree or disagree?"
- State your position clearly in the introduction - do not hedge
- Each body paragraph: one main idea + evidence + specific example
- Target 260-290 words; avoid padding - quality beats length

What Is an IELTS Opinion Essay?
Verified: IELTS.org Writing Band DescriptorsDefinition
An IELTS opinion essay is a Task 2 essay type triggered by the instruction "To what extent do you agree or disagree?" - requiring the writer to state and defend one clear personal position across an entire 250-word+ essay.
The opinion essay - also called the "agree/disagree essay" - is one of the five IELTS Writing Task 2 question types. It is instantly recognisable because the prompt ends with "To what extent do you agree or disagree?" or simply "Do you agree or disagree?" Unlike a Discussion essay, where you must present two sides equally, an opinion essay demands a single, sustained position from introduction to conclusion.
The four marking criteria assessed by IELTS examiners are Task Achievement (TA), Coherence and Cohesion (CC), Lexical Resource (LR), and Grammatical Range and Accuracy (GRA), each worth 25% of your Writing band score. For opinion essays, Task Achievement is the easiest to lose marks on - and the easiest to improve with the correct structural approach.

How Do You Structure an IELTS Opinion Essay?
The correct structure for an IELTS opinion essay is a four-paragraph format: Introduction → Body Paragraph 1 → Body Paragraph 2 → Conclusion. Each paragraph has a specific function, and deviating from this structure costs marks in both Task Achievement and Coherence & Cohesion.
| Paragraph | Function | Target words | Key element |
|---|---|---|---|
| Introduction | Paraphrase prompt + state position | 40-55 words | Clear thesis sentence |
| Body 1 | First main reason supporting your view | 90-110 words | Topic sentence + evidence + example |
| Body 2 | Second reason, or counter + dismissal | 90-110 words | Topic sentence + evidence + example |
| Conclusion | Restate position + summary of main points | 40-55 words | No new ideas |
| Total | Complete essay | 260-330 words | 250-word minimum is mandatory |
Two acceptable body paragraph strategies
Strategy A - Two supporting arguments
Body 1: Reason 1 why you agree/disagree.
Body 2: Reason 2 why you agree/disagree.
Best when your position is absolute (fully agree or fully disagree).
Strategy B - Support + concede & refute
Body 1: Main argument for your position.
Body 2: Acknowledge the opposing view, then dismiss it.
Best for partial agreement or when the topic has clear counterarguments.
How Do You Write the Introduction for an Opinion Essay?
The introduction for an IELTS opinion essay has exactly two jobs: paraphrase the prompt in your own words, and state your clear position in a thesis sentence. It should be 40-55 words and must never copy the original wording of the question.
Introduction formula
- 1
Background sentence
Paraphrase the topic (not the question). Change vocabulary, word class, and sentence structure. Do not copy more than 3 consecutive words from the prompt.
- 2
Thesis statement
State your position clearly. Use "I would argue that…", "I firmly believe that…", or "This essay contends that…". One sentence. Unmistakably shows the examiner your view.
Example - Band 7+ introduction
"The dramatic increase in fast food consumption has sparked debate over whether governments should intervene by banning such products entirely. While I acknowledge the serious health risks involved, I firmly believe that an outright ban is neither practical nor desirable, and that regulatory measures would prove more effective."
What NOT to write in your introduction
- ✕ Do not write "In this essay, I will discuss both sides of the argument" - this sounds like a Discussion essay.
- ✕ Do not start with a dictionary definition: "According to the Oxford Dictionary, fast food is…"
- ✕ Do not copy the question: "Some people think governments should ban fast food. I agree with this statement."
How Do You Write Body Paragraphs in an Opinion Essay?
Each body paragraph in an IELTS opinion essay must follow the PEEL structure: Point → Explanation → Evidence/Example → Link. This ensures every paragraph has a single clear focus, develops it fully, and connects back to the thesis.
| PEEL step | What to write | Sentences |
|---|---|---|
| Point (Topic sentence) | State the main idea of the paragraph. Must clearly support your thesis. | 1 sentence |
| Explanation | Explain why or how this point is true. Develop the idea with reasoning. | 2-3 sentences |
| Evidence / Example | Give a specific real-world example, statistic, or scenario to support the point. | 1-2 sentences |
| Link (Concluding sentence) | Connect the paragraph back to the thesis. Do not introduce a new idea. | 1 sentence |
Example body paragraph (annotated)
POINT"Restricting rather than banning fast food would allow governments to protect public health while respecting individual freedom."
EXPLAIN"Mandatory nutritional labelling, for instance, empowers consumers to make informed dietary choices without removing their right to choose. Similarly, restricting the placement of fast food advertisements near schools targets the most vulnerable age groups without imposing blanket restrictions on the adult population."
EVIDENCE"The United Kingdom's sugar tax, introduced in 2018, resulted in major manufacturers reformulating products to reduce sugar content by an average of 28.8%, demonstrating that fiscal regulation can change behaviour without prohibition."
LINK"These examples confirm that well-targeted policy tools can achieve meaningful public health improvements without resorting to an outright ban."
Strong topic sentence starters - avoid "I think" at paragraph level
How Do You Write the Conclusion for an Opinion Essay?
The conclusion for an IELTS opinion essay must restate your position in new words and briefly summarise your two main supporting points. It should be 40-55 words, contain no new arguments, and end the essay with a definitive, confident statement.
Conclusion formula
- 1
Conclusion signal phrase
"In conclusion," / "To conclude," / "In summary,"
- 2
Restate your position
Paraphrase your thesis (different words, same idea).
- 3
Summary sentence
Refer back to your two main arguments in one sentence.
Never do this
- ✕ Introduce a new argument or example.
- ✕ Write "I hope the government will do something."
- ✕ End mid-argument without a clear final sentence.
Strong conclusion phrases
- "In conclusion, I maintain that…"
- "On balance, the evidence strongly supports…"
- "For these reasons, I am firmly of the view that…"
Band 8 Model Answer (With Examiner Notes)
Verified: IELTS Band DescriptorsThe following is a complete Band 8 model essay on a common IELTS opinion essay topic. Read the full essay first, then study the paragraph-by-paragraph examiner commentary to understand exactly what earns a Band 8 score on each of the four criteria.
Task Question
Some people think governments should ban fast food because of the serious health risks it poses to modern society. To what extent do you agree or disagree?
Model Answer - Band 8
The rapid proliferation of fast food outlets has coincided with a marked rise in obesity and diet-related illness worldwide, prompting calls for state intervention. I firmly believe that a complete government ban on fast food is neither feasible nor appropriate, and that targeted regulation combined with public education represents a more effective approach.
The case for an outright ban is understandable. Fast food is frequently high in saturated fat, sodium, and refined sugar - ingredients that, when consumed regularly, contribute to cardiovascular disease, type 2 diabetes, and obesity. In countries where fast food consumption is highest, healthcare systems bear enormous financial burdens as a result. A ban would, in theory, remove this risk at source.
Nevertheless, prohibitive policy is deeply problematic in practice. First, it infringes on individual autonomy - democratic societies generally resist governments dictating what adults may eat. Second, bans are notoriously difficult to enforce and frequently produce black-market alternatives that are less regulated and potentially more harmful. More constructively, governments can impose nutritional labelling requirements, restrict fast food advertising near schools, and levy a sugar and fat tax whose revenue funds public health campaigns. These measures modify consumer behaviour without eliminating choice. The United Kingdom's Soft Drinks Industry Levy (2018), for example, prompted major manufacturers to reformulate products, reducing sugar content by an average of 28.8% in eligible drinks - a concrete, measurable public health outcome.
In conclusion, while the health risks associated with fast food are real and serious, an outright ban is an overreaction that disregards personal freedom and ignores more practical alternatives. I would argue that smart regulation and sustained education campaigns will prove far more effective in the long term than prohibition.
Paragraph-by-Paragraph Examiner Commentary
Introduction
[TA] [CC]Topic is paraphrased accurately - "proliferation of fast food outlets" replaces "governments should ban fast food". Thesis is clear and takes a definite position: disagrees with a ban, proposes regulation instead. Two-sentence structure (context + thesis) is clean and efficient.
Body Paragraph 1 - Case FOR a ban
[TA] [LR] [GRA]Opens with "The case for an outright ban is understandable" - acknowledges the opposing view before Body 2 dismisses it. Three precise health risks cited (cardiovascular disease, type 2 diabetes, obesity). Vocabulary: "proliferation", "diet-related illness", "saturated fat". Passive voice used correctly in final sentence.
Body Paragraph 2 - Against the ban + alternatives
[TA] [CC] [LR] [GRA]Transition "Nevertheless" signals shift cleanly. Two arguments against a ban (autonomy + enforcement) are distinct and well-developed. Specific real-world evidence: UK Soft Drinks Industry Levy with a quantified outcome (28.8% sugar reduction). Lexical range: "prohibitive policy", "black-market alternatives", "nutritional labelling requirements". Conditional structures show grammatical range.
Conclusion
[TA] [CC]Restates position without repeating the exact wording of the introduction - "an overreaction that disregards personal freedom" is new phrasing. No new information introduced. Final sentence reinforces the essay's core argument. Meets the 2-3 sentence conclusion target.

What Are the 3 Most Common IELTS Opinion Essay Mistakes?
These three mistakes account for the majority of Task Achievement band drops in opinion essays. Each example shows a real before/after to help you identify and avoid the error in your own writing.
Why it costs marks
IELTS Opinion essays require a single, sustained position. When candidates present both sides equally - without clearly favouring one - the examiner cannot identify their stance. This directly lowers the Task Achievement score, which is worth 25% of your total band.
Before (Band 5)
Some people think fast food is dangerous. However, others believe it is convenient and affordable. Both views have merits. In conclusion, this is a complex issue with arguments on both sides.
After (Band 7+)
While fast food does offer convenience, I firmly believe the documented health risks outweigh any benefits, and that governments should introduce stricter nutritional regulations to address this growing public health crisis.
Why it costs marks
Beginning every paragraph with "I think" or "I believe" is repetitive and reduces your Lexical Resource score. Your opinion is already established in the introduction - body paragraphs should develop arguments and evidence, not repeat your stance. It also lowers the academic register of your writing.
Before (Band 5)
In my opinion, fast food is bad. I think it causes obesity. I believe the government should do something about it.
After (Band 7+)
The health consequences of frequent fast food consumption are well-documented. Diets high in saturated fat and refined sugar are directly linked to rising rates of obesity and type 2 diabetes - conditions that place a significant burden on national healthcare systems.
Why it costs marks
A conclusion must do two things: restate your position (without copying the introduction word for word) and summarise your main arguments. Introducing a new argument in the conclusion confuses the examiner and signals poor essay planning. It can also push your word count over 300 unnecessarily.
Before (Band 5)
In conclusion, fast food is dangerous. Also, governments should invest more money in sports facilities to encourage people to exercise. This is another important solution.
After (Band 7+)
In conclusion, while the health dangers of fast food are undeniable, an outright ban would infringe on personal freedom and prove difficult to enforce. Targeted regulation and sustained public education campaigns represent a far more practical and effective strategy.
