You've written a solid paragraph. Grammar's clean. Vocabulary's sophisticated. Then the examiner reads your supporting example and thinks, "That's it?" Weak evidence kills high bands. Full stop.
Here's the thing: examiners don't penalize you for having one weak example. They penalize you for using examples that don't actually prove your point. The IELTS band descriptors for Task Response specifically reward candidates who support their position with "relevant, specific, and well-developed examples." That word—"specific"—matters. Vague examples don't count.
This guide teaches you exactly how to spot weak evidence before you submit, and how to transform it into the kind of concrete support that pushes you from Band 7 to Band 8. Use it alongside an IELTS writing checker to catch weak examples in real time.
Weak examples share three things in common. They're too general. They don't directly support your claim. And they take up space without adding proof.
Let's say the prompt is: "Some people believe that modern technology has improved our quality of life. Others argue it has made life worse. Discuss both views and give your opinion."
Weak: "Technology has changed our lives. For example, computers and phones are everywhere now, and people use them all the time. This shows that technology is important."
Why is this weak? It doesn't prove anything. Saying "computers exist" and "people use them" doesn't actually show quality of life improved. You've stated a fact, not provided evidence.
Good: "Technology has demonstrably improved healthcare outcomes. Diagnostic tools like MRI scanners enable doctors to detect cancers at earlier stages, increasing five-year survival rates from approximately 40% to 70% in developed nations. This means patients live longer, healthier lives."
The second example works. It names the technology (MRI scanners). It shows the mechanism (earlier detection). It includes data (40% to 70%). It connects back to the claim (longer, healthier lives = improved quality of life).
You mention something broadly without narrowing down. "Many people now work from home because of the internet" is true but tells us nothing about whether this is good or bad.
Weak: "Social media affects young people. They spend time on it and it changes their behavior. This is why social media is bad."
Good: "Social media creates measurable anxiety in teenagers. Studies show adolescents who spend over three hours daily on platforms like Instagram report 40% higher rates of depression and sleep disruption. The constant comparison to curated peer content triggers dopamine-seeking behavior that mirrors addiction pathways."
You invent an example that could happen instead of using one that has happened. Examiners can tell the difference, and invented examples weaken your credibility.
Weak: "If a company decided to reduce working hours to four days a week, employees might be happier and possibly more productive."
Good: "Microsoft Japan piloted a four-day working week in 2019 and measured a 40% productivity increase while maintaining full wages. Employee satisfaction scores rose, and the company reduced operational costs."
Your example is real and specific, but it doesn't actually support your argument. You've got the right shape of evidence but the wrong content.
Weak: "Renewable energy is important. Wind farms in Denmark have 8,000 turbines. This shows we should use more renewable energy."
Wait. Denmark has turbines—so what? That doesn't prove renewable energy should be used more. You've given a fact that's disconnected from your reasoning.
Good: "Renewable energy reduces carbon emissions more cost-effectively than fossil fuels. Denmark generates 80% of its electricity from wind power and has achieved the lowest carbon emissions per capita in the EU, proving that scaling renewable sources directly lowers environmental impact without harming economic output."
Here's a quick way to check if your evidence evaluation will pass an IELTS writing checker and earn Band 7+. Ask yourself these questions about every example you use.
If you answer "no" to any of these, your example needs work.
Tip: Band 8 for Task Response requires "fully addresses the prompt with relevant, extended, well-developed ideas." Extended development means your example takes 3-4 sentences, not one. You explain the mechanism, provide specifics, and link it back to your claim. One-liners belong in Band 5 essays.
Let's apply this to actual IELTS prompts. Here's a common one:
Prompt: "Some people think that spending a lot of money on national celebrations and public events is a waste of taxpayers' money. Others think that such spending is important for society. Discuss both views and give your opinion."
A weak response might write: "Public events bring communities together, which is good." That's true but empty.
Good: "Public events create measurable economic and social returns. The UK's 2012 London Olympics, which cost approximately 9 billion pounds, generated over 12 billion pounds in long-term tourism revenue, created 100,000 permanent jobs in infrastructure and hospitality, and produced a documented 25% increase in youth sports participation in participating communities. The immediate expenditure functioned as an investment rather than a loss."
See the difference? Numbers. Mechanisms. Proof. This is the type of supporting evidence that earns high scores on Task Response.
You can't wish your examples into existence. Here's the system.
Write out your main argument in one clear sentence. Not a paragraph. One sentence. "Technology improves healthcare outcomes" is clearer than "technology is good for society."
What specific evidence would prove your claim true? Not just support it weakly, but actually demonstrate it. For a healthcare claim, you need data on survival rates, treatment access, or cost efficiency. Not just "hospitals exist."
Draw on case studies you know well. Historical events. Published statistics. Personal observations that are widely verifiable, like how smartphones changed communication patterns. Avoid inventing numbers or scenarios.
Don't assume your examiner will connect the dots. "Japan's aging population, combined with their adoption of robotics in elderly care, means robots reduce the burden on healthcare workers" is better than "Japan uses robots."
Tip: Spend 90 seconds before you write to plan two or three concrete examples you'll use. Don't discover them mid-paragraph. Planned examples are developed examples. Band 8 writers know their evidence before they start writing.
Mistake 1: Using "for example" but giving no example. "For example, people benefit from the internet." That's not an example. An example has specifics. Fix it: "For example, telemedicine platforms like Teladoc enable rural patients without specialist access to consult cardiologists within 24 hours, reducing treatment delays from months to days."
Mistake 2: Piling on adjectives instead of details. "Technology is amazing and wonderful and has really good impacts." Weak. Replace subjective language with objective proof: "Technology increases productivity. Call center workers using CRM software handle 35% more customer queries per shift while maintaining satisfaction scores above 8/10."
Mistake 3: Switching between topics mid-example. You start explaining how solar energy reduces costs, then suddenly mention climate change. Pick one claim per example. Develop it fully. Then move to the next.
Mistake 4: Assuming common knowledge counts as evidence. Everyone knows smartphones exist. That's not an argument. You need the mechanism or impact: "Smartphones democratized financial access. 1.2 billion unbanked individuals in developing nations now access banking services through mobile money platforms, generating personal credit histories previously unavailable to them."
IELTS Task 2 gives you 40 minutes for a 250-word minimum essay. You'll spend roughly 25-30 minutes writing, leaving time for checking.
Strong evidence usually takes 2-3 sentences, sometimes 4. It's not about length; it's about completeness. A three-sentence example that proves your point beats a ten-sentence ramble that doesn't.
In a 350-word essay—realistic for Band 7+—you'll have 2-3 main body paragraphs. Each should contain 1-2 developed examples. That's roughly 100-150 words of evidence per paragraph, leaving room for topic sentences and analysis.
Tip: Don't pad. If your example fits in one sentence without losing specificity, use one sentence. Quality beats quantity. A Band 7 essay with two gold-standard examples beats a Band 5 essay with four weak ones.
When examiners score Task Response, they're asking these questions about your evidence. You should too.
If you can check all five boxes, you've got Band 7+ material. If you're fuzzy on three or more, rewrite the example. When you're unsure, try an IELTS writing checker to get instant feedback on whether your examples meet these criteria.
If you're working on building stronger body paragraphs overall, our body paragraph checker guide breaks down how to structure each paragraph so examples land harder. And if you catch yourself repeating the same example type across paragraphs, this guide on detecting repetitive examples will show you how to diversify your evidence.
The best way to spot weak evidence is to see how an experienced evaluator assesses it. When you're editing your essays, use our free IELTS writing checker to get instant feedback on whether your examples are specific enough, whether they actually support your claims, and which sentences need strengthening.
You'll also want to check for argument strength issues that go hand-in-hand with weak evidence. Our argument strength checker guide shows you how to identify when examples prop up weak claims versus when they genuinely prove your point.
Use our IELTS writing checker to identify weak evidence before you submit. Get instant feedback on your examples, band score estimates, and line-by-line corrections.
