IELTS Opinion Essay: How to Reach Band 8 in Writing Task 2
Quick answer: A Band 8 opinion essay states one clear position in a two-sentence introduction, develops exactly one idea per body paragraph with an explanation and a concrete example, acknowledges the other side in one sentence, and closes with a two-sentence conclusion. Plan for five minutes, write 270 to 300 words, and keep five minutes to proofread.↗ Share on X
A Band 8 opinion essay does four things that a Band 6 or 7 essay does not. It states a clear position in the introduction and never drifts from it. It builds each body paragraph around one idea and extends that idea with explanation and a specific example. It uses precise vocabulary with very few errors. And most of its sentences are grammatically error-free, with a mix of simple and complex structures. You can hit all four in 40 minutes if you plan for five minutes before you write a word.
The rest of this article shows you how, with a model question, paragraph templates, and a timing plan.

IELTS Spelling Mistakes: A 4-Week Fix for Task 1 and Task 2 →IELTS Writing Task 2 is marked on four criteria, each worth 25% of your score. Here is what the public band descriptors ask for at Band 8, in plain words:
| Criterion | What Band 8 looks like |
|---|---|
| Task Response | You answer every part of the question, your position is clear throughout, and your ideas are well developed and supported |
| Coherence and Cohesion | Information flows logically, paragraphs are used well, and linking words are used naturally, not stuffed in |
| Lexical Resource | A wide range of vocabulary used precisely, with rare spelling or word-choice slips |
| Grammatical Range and Accuracy | A wide range of structures, and the majority of sentences have no errors |
Notice what is not on the list: long words, memorized phrases, or a 400-word essay. Band 8 rewards control, not decoration.

Step 1: read the question twice and pick one side
Opinion questions end with "To what extent do you agree or disagree?" or "What is your opinion?" Here is a model question we will use throughout:
Some people think that governments should spend money on public transport rather than on building new roads. To what extent do you agree or disagree?
Spend your first five minutes on three things:
1. Underline the exact claim. Here it is "public transport rather than roads." Not "transport is important." The essay must compare the two.
2. Pick a clear position. Agree, disagree, or agree with a stated limit. Write it in one sentence on your question paper. Example: "I largely agree, because public transport serves more people per dollar, although some roads are still needed in rural areas."
3. Choose two main ideas, one per body paragraph. For this position: (a) public transport moves more people at lower cost per person, and (b) it reduces congestion and pollution that new roads tend to increase.
If you cannot write your position in one sentence, you do not have a position yet. Do not start writing until you do.
Step 2: write a two-sentence introduction

IELTS Speaking Part 1: A 3-Step Formula for Longer Answers →Band 8 introductions are short. Two sentences are enough:
1. Paraphrase the topic in your own words.
2. State your opinion and signal your two reasons.
Model introduction:
Many argue that public funds are better spent on buses and trains than on expanding road networks. I largely agree with this view, because public transport carries more people for the same investment and helps reduce the congestion that new roads often make worse.
That is 46 words. It tells the examiner your position and your plan. Do not add a sentence about how "transport is a hot topic in today's world." It earns nothing.
Step 3: build each body paragraph on one idea
Use this four-part shape for each body paragraph:
- Topic sentence: the idea in one line.
- Explanation: why it is true, in two or three sentences.
- Example: one specific case. It can be hypothetical, but it must be concrete.
- Link: one sentence tying it back to your position.
Model body paragraph one:
The strongest reason to prioritize public transport is that it moves far more people for the same budget. A single rail line or bus corridor can carry tens of thousands of passengers a day on a strip of land narrower than a highway, whereas an extra road lane serves only the cars that fit on it. For example, a city that builds a dedicated bus lane on a busy route can carry a full busload of commuters in the space one or two cars would occupy. Given that most governments have limited budgets, spending where each dollar serves more citizens is the more responsible choice.
Four sentences, one idea, one example, one link. That paragraph is around 100 words. Two paragraphs like it, plus introduction and conclusion, lands you at 270 to 300 words, which is the right length.
Step 4: handle the other side without losing your position
Band 8 essays often acknowledge the opposing view, but they do it in one or two sentences inside a body paragraph, not in a separate paragraph that argues against the writer. The word "although" is your friend:
Although new roads are sometimes necessary, especially in rural areas with no rail or bus coverage, in cities they tend to attract more traffic until congestion returns to its previous level.
You have shown balance and kept your position. Compare this with the common Band 6 mistake: writing one paragraph for, one against, and then saying "in conclusion, both sides have a point." That is not a position, and Task Response drops.
Step 5: write a two-sentence conclusion
Restate your position in different words and summarize the two reasons. Nothing new.
In conclusion, while some road building remains unavoidable, I believe governments should direct most transport funding to buses and trains. They serve more people per dollar and address the congestion and pollution that additional roads rarely solve.
Do not end with "Thank you" or a question. Do not introduce a third reason here.
What does Band 8 vocabulary look like?
Precision, not difficulty. Here are swaps that move a sentence from Band 6 to Band 8 territory:
| Band 6 phrasing | Band 8 phrasing |
|---|---|
| "spend money on" | "allocate funding to" or "invest in" |
| "a lot of people" | "a large share of commuters" |
| "bad for the environment" | "increases emissions" or "worsens air quality" |
| "traffic gets worse" | "congestion returns" or "demand rises to fill the new capacity" |
| "very important" | "essential" or "a priority" |
Use topic-specific words naturally: congestion, commuters, infrastructure, capacity, emissions, rural coverage. Avoid memorized phrases like "a double-edged sword" or "every coin has two sides." Examiners see them in thousands of essays and they signal a template, not control.
Which grammar structures show range?
You do not need every structure. You need four or five, used correctly:
1. Complex sentences with "although," "whereas," and "while."
2. Conditionals: "If a city invests in rail, car use tends to fall."
3. Relative clauses: "a road lane, which serves only the cars that fit on it, ..."
4. Passive voice where it fits: "Public funds are better spent on..."
5. Comparatives: "far more people," "a narrower strip of land."
Then check accuracy. The descriptor says "the majority of sentences are error-free." One article mistake per paragraph is already pushing it. Leave three minutes to proofread for articles, subject-verb agreement, and plural endings.
A 40-minute plan that works under pressure
1. Minutes 0 to 5: read twice, write your one-sentence position, choose two ideas and one example each.
2. Minutes 5 to 9: introduction, two sentences.
3. Minutes 9 to 20: body paragraph one.
4. Minutes 20 to 31: body paragraph two, including your "although" sentence.
5. Minutes 31 to 35: conclusion.
6. Minutes 35 to 40: proofread. Check the position is the same in introduction and conclusion, then hunt for grammar slips.
If you run out of time, a short conclusion beats no conclusion. An essay without one loses marks for Task Response and Coherence.
Mistakes that keep good writers at Band 7
- Drifting position. The introduction says "largely agree," body paragraph two argues the opposite, and the conclusion says "it depends."
- Two ideas in one paragraph. Neither gets developed, so the examiner cannot give credit for extension.
- Vague examples. "For example, many countries have done this" is not an example. Name a type of city, a type of project, a concrete outcome.
- Overusing linkers. "Firstly, moreover, furthermore, in addition, however" in every sentence reads as mechanical.
- Writing over 350 words. More words mean more errors and less time to check.
Your next step
Set a timer for 40 minutes and write a full answer to the model question above, using the five-minute plan and the four-part paragraph shape. When the timer stops, check three things: is your position identical in the introduction and the conclusion, does each body paragraph contain exactly one idea with one concrete example, and can you find any sentence with a grammar error? Fix those three, and write a second essay tomorrow on a different question. Two essays a week with this check is enough to move a band in a month for most people who are already at Band 6.5 or 7.
FAQ
How many words should a Band 8 Task 2 essay have?
Aim for 270 to 300 words. The minimum is 250, and going well beyond 350 usually adds errors and costs you proofreading time without adding marks.
Should I discuss both sides in an opinion essay?
You can acknowledge the opposing view in one or two sentences inside a body paragraph, but your position must stay the same from introduction to conclusion. A separate paragraph arguing against yourself weakens Task Response.
Do I need advanced vocabulary for Band 8?
You need precise vocabulary, not rare words. Topic-specific terms used correctly, such as congestion, commuters, and allocate funding, score higher than memorized idioms like a double-edged sword.
