The single most expensive mistake in IELTS Task 2 is not bad grammar or weak vocabulary — it is writing the wrong shape of essay for the prompt. A candidate who writes a polished opinion essay in response to a discussion question loses heavy marks on Task Response, often dropping a full band even when the English is otherwise Band 7+. Discussion and opinion prompts look almost identical at a glance: both ask for your view, both want two body paragraphs, both end with a conclusion. The structural difference is small but unforgiving. This post shows you how to spot which type you are facing in under thirty seconds, then gives you a clean paragraph template, sample thesis statements, and the failure mode to avoid for each.
The Two Prompts, Side by Side
Read these two questions carefully. They are the actual language IELTS uses, almost word for word, across hundreds of past papers.
Opinion prompt: “Some people believe that schools should ban mobile phones in classrooms. To what extent do you agree or disagree?”
Discussion prompt: “Some people believe schools should ban mobile phones in classrooms. Others argue that phones can support learning. Discuss both views and give your own opinion.”
Same topic. Same level of formality. Almost the same first sentence. But the task — what the examiner is asking you to do on the page — is different.
| Opinion essay | Discussion essay | |
|---|---|---|
| Trigger phrase | To what extent do you agree or disagree? | Discuss both views and give your own opinion. |
| Number of views you must cover | One (yours) — though acknowledging the other view is a Band 7+ move | Two (both sides) — non-negotiable, plus your own |
| Body paragraph 1 | First reason supporting your view | The first view, fairly explained |
| Body paragraph 2 | Second reason supporting your view (or counter + rebuttal) | The second view, fairly explained |
| Where your opinion goes | Stated in the introduction and reinforced throughout | Stated in introduction and developed in conclusion (or in a third short paragraph) |
| Most common failure | Sitting on the fence, refusing to pick a side | Treating it as an opinion essay and ignoring one of the views |

How to Spot Which Type You Are Facing
Spend the first sixty seconds of Task 2 doing nothing but reading the prompt. Identify the question type before you start planning. The signal words below decide everything that follows.
Opinion essay signals
If the prompt ends in any of these, it is an opinion essay:
- To what extent do you agree or disagree?
- Do you agree or disagree?
- What is your opinion?
- Do the advantages outweigh the disadvantages? (a specific opinion variant — you are arguing one direction)
Discussion essay signals
The discussion essay almost always uses this exact phrasing or a near variant:
- Discuss both views and give your own opinion.
- Discuss both these views and give your own opinion.
- Discuss both sides of the argument and give your opinion.
The presence of two opposing views earlier in the prompt (“Some people believe X. Others argue Y.”) is also a strong discussion signal.
A useful rule of thumb: if the prompt presents two views in the body of the question and asks you to discuss both, it is a discussion essay. If it presents one view (or a single statement) and asks how far you agree, it is an opinion essay. Get this read right and the rest is structure.
For a refresher on the other Task 2 types you might also see, the broader question-type taxonomy is covered in our post on IELTS Academic writing mistakes, point three.
Opinion Essay Structure
The opinion essay is one-sided. You pick a position in the introduction, defend it across two body paragraphs, and restate it cleanly in the conclusion. The structure below produces a 270–290 word response that hits all four marking criteria.
Paragraph template
- Introduction (45–55 words) — Paraphrase the prompt, then state your position clearly.
- Body paragraph 1 (90–110 words) — Strongest reason supporting your view, with a specific example.
- Body paragraph 2 (90–110 words) — Second reason, or a brief acknowledgement of the opposing view followed by a rebuttal.
- Conclusion (35–45 words) — Restate your position in different words, summarise the two reasons, end forward-looking.
Sample thesis statements
The thesis is the second sentence of your introduction. It should make your position unmissable.
- Strong agreement: “This essay will argue that mobile phones have no legitimate place in school classrooms, primarily because they undermine concentration and create avoidable inequality between students.”
- Strong disagreement: “This essay will argue that an outright ban is misguided; the focus should instead be on teaching students to use phones responsibly as learning tools.”
- Partial agreement (the most common Band 7+ choice): “While there are legitimate concerns about classroom distraction, this essay will argue that a complete ban goes too far and that supervised, purpose-driven phone use brings clear educational benefits.”
Partial agreement is the safest play for most prompts because it lets you concede ground without sitting on the fence. The danger to avoid is full fence-sitting (“There are good points on both sides”) — that reads as failure to take a position, which is a direct hit on Task Response.
What goes wrong in opinion essays
The classic failure mode is the balanced essay disguised as an opinion. The candidate writes one paragraph supporting the view, one paragraph opposing it, and a conclusion that says “both sides have valid points”. The examiner reads this as a discussion essay and marks it accordingly — except the introduction promised an opinion, so the essay is judged inconsistent with its own task. Result: Task Response capped at 5 or 6.
The fix is mechanical. If your introduction says “I agree” or “I disagree”, every body paragraph must support that claim. If you mention the other side, do it briefly and only to dismiss it.
Discussion Essay Structure
The discussion essay is two-sided. You explain each view fairly — not just the one you personally hold — and then state your own opinion clearly. The temptation is to short-change the view you disagree with. Resist it. Examiners specifically check that both views are developed.
Paragraph template
- Introduction (45–55 words) — Paraphrase the two views, then state your own opinion.
- Body paragraph 1 (80–100 words) — Explain View A, with a reason and example. Do not yet say whether you agree.
- Body paragraph 2 (80–100 words) — Explain View B, with a reason and example. End with a sentence connecting it to your own position.
- Conclusion (40–55 words) — Restate your opinion clearly, briefly say why it carries more weight than the alternative.
A common variant adds a short third body paragraph (40–60 words) where you explicitly defend your own view. This is fine if you are a fast writer; otherwise fold the defence into your conclusion.
Sample thesis statements
In a discussion essay, the thesis must do two jobs: signal that you will cover both views, and state your own opinion.
- “This essay will examine both the case for banning phones and the case for integrating them as learning tools, before arguing that the latter approach better serves modern classrooms.”
- “While some maintain that university tuition should be free at the point of use and others argue that students themselves should bear the cost, this essay will discuss both positions and side with a hybrid model in which the state covers core costs and graduates contribute through later income-linked repayment.”
- “The arguments for and against renewable energy subsidies will both be examined, but on balance this essay will argue that targeted public support remains essential during the transition phase.”
Notice that each thesis names both views and names a position. Skipping the position is the most common mistake — the prompt explicitly asks for your own opinion, and an introduction that omits it loses Task Response marks before the first body paragraph is written.
What goes wrong in discussion essays
Three failure modes recur:
- Treating it as an opinion essay and only developing the side you agree with. This is the worst version. The instruction “Discuss both views” is non-negotiable.
- Refusing to give an opinion. The reverse mistake — discussing both sides fairly but never stating which one you find more convincing. The prompt asks for your own opinion; not giving one is a direct refusal of the task.
- Mentioning your opinion only in the conclusion. Examiners want your position visible from the introduction onward. A discussion essay that hides its thesis until the last paragraph reads as an essay that did not know what it thought.
For a closer look at the language that makes balanced argument feel mature rather than wishy-washy, our list of IELTS Band 7+ phrases covers the concession-and-counter structures that work especially well in this essay type.
A Side-by-Side Sample: Same Topic, Two Essays
To make the structural difference unmistakable, here are the opening paragraphs of two responses to almost identical prompts on the same topic.
Opinion essay opening
Prompt: Some people believe that working from home is more productive than working in an office. To what extent do you agree or disagree?
“It is increasingly argued that home working delivers higher productivity than traditional office arrangements. While this view contains some merit in specific industries, this essay will largely disagree, arguing that the productivity gains are uneven across roles and are often offset by weaker collaboration and slower onboarding of junior staff.”
One position, stated unmissably, with a hint of nuance (“largely disagree”) to avoid the fence-sitting trap.
Discussion essay opening
Prompt: Some people believe that working from home is more productive than working in an office. Others argue that office work fosters better collaboration and faster learning. Discuss both views and give your own opinion.
“Whether remote or office-based work delivers better outcomes is a debate that has only intensified since 2020. Proponents of home working point to deeper focus and saved commuting time, while defenders of the office emphasise the value of in-person collaboration and mentoring. This essay will discuss both positions before arguing that a hybrid model captures the strengths of each while mitigating the weaknesses.”
Both views named in the introduction, and the writer’s position made explicit before the body paragraphs begin.
The body paragraphs would also differ: the opinion essay’s two body paragraphs would each defend the disagree position, while the discussion essay’s would explain each view neutrally before the conclusion picks a side.
Time and Word Count for Both Types
Both essay types follow the same time and word-count budget — only the internal structure differs.
| Opinion essay | Discussion essay | |
|---|---|---|
| Total time | 40 minutes | 40 minutes |
| Planning | 3–5 minutes | 4–6 minutes (you need to plan two views) |
| Word count | 270–300 words | 280–310 words |
| Body paragraph length | 90–110 each | 80–100 each |
| Number of body paragraphs | 2 | 2 (occasionally 3 if defending your opinion separately) |
If you are running short on time, sacrifice length from the conclusion before the body paragraphs — body paragraphs do most of the Task Response and Coherence work, while conclusions earn diminishing returns above forty words. The same time-management logic that applies to Task 1 chart questions like pie charts — pick what matters, cut what does not — applies here.
Quick-Reference Decision Tree
When the test paper lands and you read the Task 2 prompt, run through this check in order:
- Does the prompt say “Discuss both views” (or a near variant)? → Discussion essay. Two views, then your opinion.
- Does the prompt say “To what extent do you agree or disagree?” or “What is your opinion?” → Opinion essay. Pick a side.
- Does the prompt mention advantages and disadvantages? → A different question type — usually treated as a discussion variant where you weigh the two sides.
- Does the prompt ask two distinct questions? → A two-part question — a fourth structural type, where each body paragraph answers one of the questions.
- Still not sure? Re-read the final sentence of the prompt slowly. The instruction is always there in the last line.
Sixty seconds spent on this triage is the single highest-leverage minute in your Task 2.
Final Tip
The candidates who jump from Band 6.5 to Band 7+ on Task 2 are rarely the ones who learned new vocabulary that month. They are the ones who stopped writing every essay the same way, recognised which structure the prompt was actually asking for, and matched it cleanly. Try this exercise tonight: take five past Task 2 prompts (the official IELTS sample papers are full of them), and for each one write only the introduction — paraphrase plus thesis. Compare your introductions to the templates above and you will see immediately whether you can spot the type. Once that read is automatic, the body paragraphs follow.

And before you sit the test, run a quick check against what counts as a good IELTS score for your specific goal so you know exactly which band on Task 2 you are aiming for.
