You're stuck at Band 6. Your essays are organized. Your grammar is solid. But the examiner keeps marking you down on Task Response. Here's the real issue: your evidence is too vague, too generic, or doesn't actually connect to your argument.
This is where most students stumble. They think jumping from Band 6 to 7 means writing longer sentences or throwing in fancy vocabulary. Wrong. It's about backing up your ideas with specific, relevant examples that actually prove your point, not just support the general topic.
In this guide, you'll learn exactly what makes evidence weak, how to spot it in your own writing, and how to fix it so examiners see you deserve a 7. You can also use our free IELTS writing checker to evaluate your essay evidence in real time.
Band 6 essays often scrape by because the structure exists. Introduction, body paragraphs with main ideas, conclusion. But the supporting details? They're shallow. You mention something without really proving anything.
According to the IELTS Band Descriptors, Band 6 means you "present relevant main ideas but some supporting points are underdeveloped or repetitive." Band 7 says you "develop your main ideas fully and support with relevant, specific examples."
That's the gap. One has weak evidence. The other has strong evidence.
Band 6 Example (Weak): "Young people spend too much time on social media. This is bad for their mental health. Studies show it causes depression and anxiety."
Band 7 Example (Strong): "Research from the University of Pennsylvania found that limiting social media use to 30 minutes daily reduced loneliness and depression scores by 40% over three weeks. This suggests that quantifiable restrictions, not outright bans, can protect adolescent mental health while maintaining social connection."
See the difference? The weak version throws out a claim and hopes you'll accept it. The strong version gives you a source, specific numbers, and explains why it actually matters to the argument.
Examiners read thousands of essays. They can smell fabricated data. If you can't remember an exact figure, don't invent one. Use softer language instead: "numerous studies suggest" or "research indicates."
Weak: "75.3% of teachers believe homework should be abolished."
Strong: "Many teachers report that excessive homework reduces student motivation and increases burnout, particularly at secondary level."
You're arguing that remote work boosts productivity. Then you mention your uncle works from home and owns a cat. That's not evidence, that's filler that wastes your word count.
Weak: "Technology has changed education. For example, my school has new computers. I like using them because they're fast."
Strong: "Technology has democratized education. Online platforms like Khan Academy and Coursera provide free, high-quality instruction to students in developing countries who lack access to university libraries or specialist tutors."
You mention the same example three times in different words. This screams "I don't have enough ideas." Each paragraph in your IELTS essay should bring new supporting evidence that builds on what came before.
You drop a fact and move on. You never explain why it proves your point. The examiner isn't a mind reader. Draw the connection for them.
Weak: "Government subsidies for public transport are important. In Germany, ticket prices are lower than in the UK."
Strong: "Government subsidies for public transport increase usage rates. In Germany, subsidized fares led to a 30% increase in commuter numbers, which reduced traffic congestion and lowered carbon emissions by 12% in major cities. This demonstrates that affordable transport directly influences both environmental and social outcomes."
Everyone already knows exercise is healthy. Saying that doesn't earn you marks. You need specific knowledge or an angle that others might miss.
Weak: "Exercise is good for you and makes you healthier."
Strong: "Workplace exercise programs have measurable benefits. Companies that provide on-site fitness facilities or subsidized gym memberships report 15% lower absenteeism and higher employee retention rates, making health investment a cost-effective business decision."
Before you submit your IELTS essay practice, run through this checklist. Every piece of evidence should pass at least four of these five tests.
You won't have time to research during the IELTS exam. But you can build a personal evidence bank during practice that stays with you.
Spend 15 minutes brainstorming 5 to 10 common IELTS topics. For each one, write down 3 to 5 specific examples: a country, a real statistic you can reliably remember, a historical event, a recent trend you've read about.
Let's say your topic is "Should governments fund space exploration?" Your evidence bank might include:
These aren't made up. They're real, specific, and memorable. When you practice essays on this topic, you'll use different angles from this bank, and your supporting evidence will feel naturally confident.
Tip: Write your evidence bank in a notebook. Don't memorize speeches. Understand the ideas deeply enough that you can explain them naturally in your own words during the exam.
Take this real prompt: "Some people believe that modern technology is creating a more equal world, while others argue it is increasing inequality. Discuss both views and give your opinion."
Here's a Band 6 response arguing that technology creates equality:
Weak: "Technology creates equality because now poor people can access information. The internet is cheap and everyone can use it. This helps people learn new skills and find better jobs. Technology is definitely making the world more equal."
And here's the Band 7 version making the same argument:
Strong: "Technology does create pathways to equality, particularly in developing countries. Mobile phone penetration in Africa has risen from 2% in 2000 to over 50% today, enabling small business owners in rural areas to access payment systems and markets previously unavailable to them. Similarly, free online courses from platforms like Coursera allow individuals in low-income regions to gain certifications in software development and data analysis without paying university tuition, directly competing in global job markets."
Same argument. Roughly the same word count. Completely different impact.
You say "it could be argued" and "it seems that" and "in some cases" for every statement. This makes you sound uncertain and dilutes your evidence.
Weak: "It could arguably be suggested that social media might possibly have some negative effects on young people's mental health in certain circumstances."
Strong: "Excessive social media use correlates with higher rates of anxiety and depression among teenagers. Evidence shows that limiting usage reduces these symptoms."
You write facts next to each other but don't connect them. The reader has to make the logical leap themselves.
Weak: "Finland has a strong education system. The country invests heavily in teacher training. Finnish students score well on international tests."
Strong: "Finland's investment in comprehensive teacher training directly explains its high test scores. Teachers receive extensive professional development and higher salaries, attracting top graduates to the profession. This creates a virtuous cycle where qualified educators produce higher-achieving students, demonstrating that teacher quality is the foundation of educational success."
You write "In this modern age" or "As we can see in today's society." These aren't evidence. They're just filler words.
Once you finish writing, read through and highlight every single piece of evidence (facts, examples, statistics, case studies). Ask yourself these three questions for each one.
Question 1: Could I defend this in a conversation? If someone challenged you on it, could you explain it without making things up? If the answer is no, rewrite it more carefully.
Question 2: Does this prove my specific claim or just relate to the topic? These are different things. Your claim is narrow. Your evidence should target it exactly, not just float around the general topic.
Question 3: Did I spend enough sentences explaining why this matters? One sentence of evidence isn't enough. Take 2 to 3 sentences to unpack why it's relevant to your argument. You can use our IELTS essay checker to get instant feedback on whether your evidence explanations are detailed enough.
Tip: Read your evidence out loud. If you stumble or feel like you're stretching the truth, rewrite it. Your gut instinct is usually right.
The IELTS Band Descriptors for Band 7 explicitly state that you should "support with relevant, specific examples." Band 6 says "some supporting points are underdeveloped."
Examiners use these criteria every single time. It's not arbitrary. Specific evidence is harder to produce than generic evidence. It shows you've actually thought about your argument and you're not just recycling memorized phrases from study guides.
When you shift from vague to specific, you're proving to the examiner that you understand the topic deeply enough to back up your claims with real details.
That's the difference between Band 6 and Band 7.
