IELTS Writing Task 2 Band 9 Sample Essays: What Perfect Scores Look Like
Reading time: 15 minutes
Band 9 in IELTS Writing is extraordinarily rare — fewer than 0.1% of candidates achieve it. But studying what perfection looks like reveals patterns that can improve any writer's score, whether you are targeting Band 7 or Band 8.
This guide presents three complete Band 9 essays with detailed annotations explaining exactly why each one scores at the highest level.
What Band 9 Actually Requires
Before reading the samples, understand what the band descriptors demand at the highest level:
Task Response: The position is fully developed with well-extended, fully supported ideas. Every part of the question is fully addressed.
Coherence and Cohesion: The message is effortlessly followed. Paragraphing is skilfully managed. Cohesion does not attract attention — it feels invisible because the logic flows naturally.
Lexical Resource: A wide range of vocabulary is used with full flexibility and precision. Rare minor errors occur only as "slips" rather than systematic weaknesses.
Grammatical Range and Accuracy: A wide range of structures is used with full flexibility and accuracy. Errors are extremely rare and difficult to spot.

Sample Essay 1: Opinion Essay (Technology)
Question: Some people believe that social media has had a largely negative effect on society. To what extent do you agree or disagree?
Social media has become so deeply embedded in daily life that its effects are now impossible to separate from the broader trajectory of modern society. While critics point to genuine harms — addiction, misinformation, and the erosion of privacy — the claim that social media's overall impact has been "largely negative" oversimplifies a far more nuanced reality. I would argue that social media's effects are mixed, and that focusing exclusively on its harms obscures substantial benefits that have genuinely improved people's lives.
The most compelling case against social media concerns its impact on mental health, particularly among young people. Platforms designed to maximise engagement exploit psychological vulnerabilities, creating feedback loops that reward social comparison and punish disengagement. There is now robust evidence linking heavy social media use with increased rates of anxiety and depression in adolescents. Additionally, the algorithmic amplification of sensational and divisive content has demonstrably degraded public discourse, making it harder for citizens to distinguish reliable information from propaganda. These are serious problems that deserve serious policy responses.
However, the same platforms that enable misinformation also provide unprecedented access to information, education, and community. Marginalised groups — from LGBTQ+ youth in conservative regions to rare disease patients seeking peer support — have found connection and visibility that was simply impossible before social media existed. Small businesses in developing economies now reach global markets through platforms that cost nothing to join. Protest movements from Hong Kong to Sudan have organised and communicated through social media when traditional channels were suppressed. Dismissing these outcomes as trivial while treating the harms as definitive reflects a selective reading of the evidence.
The appropriate response to social media's mixed record is not blanket condemnation but targeted intervention: regulation of addictive design features, investment in digital literacy, and platform accountability for algorithmic amplification of harmful content. The technology itself is neither inherently destructive nor benign — its effects depend on how societies choose to govern it.
Why This Scores Band 9
Task Response: The position is clear from the introduction ("mixed" rather than "largely negative") and sustained throughout. Both sides are fully developed with specific examples. The conclusion extends the argument to propose a resolution rather than simply restating.
Coherence: The essay flows through a logical sequence: acknowledge the harms → present the counter-evidence → propose a synthesis. No paragraph feels disconnected. Cohesion is achieved through logical progression, not mechanical linking words.
Lexical Resource: Notice the precision: "exploit psychological vulnerabilities," "feedback loops," "algorithmic amplification," "selective reading of the evidence." Every word is chosen deliberately. There are no wasted phrases.
Grammar: The essay uses a remarkable range of structures naturally — complex noun phrases ("platforms designed to maximise engagement"), conditional logic ("its effects depend on how societies choose to govern it"), and passive constructions where appropriate. No grammatical errors.
Sample Essay 2: Discussion Essay (Education)
Question: Some people think that university education should be free for everyone. Others believe that students should pay their own tuition fees. Discuss both views and give your own opinion.
The question of who should pay for university education sits at the intersection of economics, social justice, and political philosophy. Those who advocate for free tuition argue from a principle of equal opportunity; those who oppose it point to practical constraints and moral hazard. Both positions contain legitimate insights, though I believe the most defensible approach lies between the two extremes.
The case for free university education rests on a straightforward equity argument: talent is distributed randomly across the population, but access to higher education is not. When tuition fees are high, capable students from low-income families face a choice that wealthier peers never confront — between pursuing education and avoiding debt. Countries that have eliminated or substantially reduced tuition fees, such as Germany and Norway, demonstrate that free higher education is fiscally achievable and that it correlates with higher social mobility. If societies benefit from having educated citizens — through innovation, productivity, and informed civic participation — then there is a collective interest in removing financial barriers to education.
The opposing view is equally grounded in practical reality. University education is expensive, and funding it entirely from public revenue means that taxpayers who never attended university subsidise those who do — a transfer that disproportionately benefits the already-privileged, since university attendance correlates strongly with parental income. Furthermore, when education is free, students may be less motivated to complete their studies or choose programmes with clear economic value, leading to inefficient use of public resources. The experience of countries with high tuition but robust loan systems, such as Australia, shows that access can be maintained without eliminating fees entirely.
In my view, the strongest approach combines elements of both positions: substantially subsidised tuition with income-contingent repayment, ensuring that no student is deterred by upfront costs while maintaining a connection between the individual benefit of education and its cost. This preserves access without creating the moral hazard of entirely free provision.
Why This Scores Band 9
Task Response: Both views are given genuinely equal, substantive treatment. The writer's opinion is clear and goes beyond simply picking a side — it synthesises a third position. Country examples (Germany, Norway, Australia) demonstrate sophisticated idea development.
Coherence: Each paragraph has a distinct function and the progression is impeccable: frame the debate → view 1 with evidence → view 2 with evidence → synthesised opinion. Topic sentences are clear without being formulaic.
Lexical Resource: "Moral hazard," "income-contingent repayment," "fiscal achievability," "disproportionately benefits the already-privileged" — this is vocabulary used with native-level precision and naturalness.
Grammar: Complex structures appear effortlessly: "talent is distributed randomly across the population, but access to higher education is not" uses parallel structure for rhetorical effect. No errors.
Sample Essay 3: Problem-Solution Essay (Environment)
Question: Many cities around the world are facing serious air pollution problems. What are the causes of this, and what measures could be taken to address it?
Air pollution in urban areas has reached levels that constitute a public health emergency in many parts of the world. The causes are well-documented and primarily structural, rooted in transport systems, industrial policy, and energy production. Addressing the problem requires equally structural solutions — not just individual behaviour change, but fundamental shifts in how cities are designed and powered.
The most significant contributor to urban air pollution is road transport. Private vehicles burning fossil fuels release nitrogen dioxide, particulate matter, and carbon monoxide directly into the air at street level, where human exposure is highest. In cities like Delhi and Beijing, vehicle emissions account for the majority of harmful pollutants. Industrial activity compounds the problem: factories and power plants operating on the periphery of cities produce sulphur dioxide and fine particulates that drift into residential areas depending on wind patterns. A less visible but equally important cause is domestic energy use — in many developing cities, millions of households still rely on wood, coal, or kerosene for cooking and heating, generating indoor and outdoor pollution simultaneously.
Effective solutions must operate at the systemic level. Investing in affordable, reliable public transit — particularly electric rail and bus networks — reduces dependence on private vehicles more effectively than any awareness campaign. Cities like Bogotá and Curitiba have demonstrated that well-designed bus rapid transit systems can transform urban air quality within years, not decades. Simultaneously, transitioning industrial energy production from coal to renewable sources addresses pollution at its largest single origin point. For domestic emissions, government subsidies that make clean cooking fuels affordable in low-income communities have proven more effective than regulation, which is nearly impossible to enforce at the household level.
The challenge is not a lack of solutions but a lack of political will to implement them against entrenched economic interests. Cities that have succeeded in reducing air pollution — London's Ultra Low Emission Zone, Beijing's coal-burning ban within city limits — did so through ambitious policy backed by consistent enforcement. The knowledge exists; what is needed is the commitment to act on it.
Why This Scores Band 9
Task Response: Both causes and solutions are fully developed with specific, concrete examples. The conclusion adds genuine analytical depth rather than simply summarising.
Coherence: Causes paragraph → solutions paragraph → analytical conclusion. Each solution directly addresses a specific cause mentioned earlier, creating a logical thread that the reader follows effortlessly.
Lexical Resource: "Constitute a public health emergency," "entrenched economic interests," "operate at the systemic level" — precise, academic, and natural. Topic-specific vocabulary (nitrogen dioxide, particulate matter, Ultra Low Emission Zone) demonstrates expertise without being unnecessarily technical.
Grammar: Effortless variety: complex sentences, dash-inserted clauses, conditional reasoning, passive and active voice used deliberately. Zero errors.
Common Patterns in Band 9 Essays
Across all three samples, notice what they share:
- No templates. These essays do not follow a visible formula. Each is structured to serve its specific argument.
- Genuine thinking. The ideas are developed, not listed. Each point leads logically to the next.
- Invisible cohesion. You barely notice linking devices because the logic itself provides the connection.
- Precise vocabulary. Every word earns its place. There are no filler phrases or unnecessary qualifiers.
- Natural complexity. Complex grammar appears because the ideas demand it, not to impress the examiner.
The Gap Between Band 8 and Band 9
If you already score Band 8, the gap to Band 9 is primarily about naturalness and polish. Band 8 essays may have occasional awkward phrasing or a moment where the vocabulary choice is not quite precise. Band 9 writing reads like published editorial content — every sentence sounds like something a skilled writer would choose to write, not something a test candidate is performing.
For more on this distinction, see our Band 7 vs Band 8 comparison.
Should You Aim for Band 9?
Honestly, most candidates should not target Band 9. If you need 7.0 or 7.5, your preparation time is far better spent perfecting the fundamentals: clear structure, precise vocabulary, and accurate grammar. Studying Band 9 essays is valuable for understanding what examiners value, but attempting to replicate this level without near-native proficiency often produces essays that try too hard and lose clarity.
Target Band 7-8 through solid fundamentals. If Band 9 is within your ability, it will emerge naturally.
How to Learn From These Essays Without Memorising Them
- Identify the structural principle. How does each paragraph relate to the question and to each other?
- Note vocabulary patterns. Which collocations and phrases could you adapt for different topics?
- Study the argument development. How does the writer move from claim to evidence to consequence?
- Practice producing, not reproducing. Write your own essay on the same question and compare your approach.
As we explain in our guide on why memorising essays destroys your score, the goal is to understand principles and develop your own voice. For vocabulary building, focus on quality over quantity and learn complex sentence structures that you can use naturally.
