Here's the thing: most students stuck at Band 6 or 7 don't have a grammar problem. They have an evidence problem. Your sentences are grammatically correct. Your vocabulary is solid. But your examples? They're vague, generic, or just plain weak. The examiner reads them and thinks, "This student has an opinion, but where's the proof?"
This is where most students mess up. They know they need examples, but they don't know how to make examples count. In IELTS Writing Task 2, weak evidence is what separates Band 7 from Band 8. Look at the Band 8 descriptor. It explicitly says "fully supported and developed ideas with relevant, specific examples." That word—specific—is what you're missing.
By the end of this guide, you'll know exactly how to spot weak evidence in your own essays, fix it, and move up the band scale. You'll have a clear checklist you can use with our free IELTS writing checker before you submit any essay.
The IELTS Writing Task 2 band descriptors are pretty clear on this. For Task Response, examiners are looking at whether you've "presented a clear position with relevant supporting ideas." Key word: relevant. Not just any idea. The right ones.
When your evidence is weak, one good sentence doesn't save your essay. You're asking the examiner to fill in the blanks for you. That's not their job. They mark what you've written, not what you meant to write.
Band 6 students provide some supporting ideas. Band 7 students provide clear, developed supporting ideas. Band 8 students provide clear, developed, specific supporting ideas that directly address the question. The jump from 7 to 8 isn't about writing more. It's about being more precise with your examples and explanations.
Not all weak evidence looks the same. You need to recognize these three patterns so you can hunt them down in your own writing.
This is evidence that's technically true but tells the examiner almost nothing.
Weak: "Social media has negative effects on young people. Studies show that it can cause mental health problems. Many teenagers use it every day, and this is bad for their development."
What's wrong? You're stating a conclusion (social media is bad) but not showing how or why. "Studies show" and "mental health problems" are so general they prove nothing. Which studies? Which mental health problems? How long until these problems develop?
Better: "Research from the Journal of Adolescent Health found that teenagers who spend more than three hours daily on social media report 35% higher rates of depression and anxiety. This happens because constant comparison with curated online personas creates unrealistic self-expectations."
Now you've named a specific source, given a concrete number, and explained the mechanism. The examiner doesn't have to guess what you mean.
You mention an example, but you don't explain why it matters to your argument. It just sits there.
Weak: "Remote work can be beneficial. For example, my cousin works from home and saves money on transportation. Additionally, some countries like Sweden have flexible working policies."
You've thrown in two examples, but neither supports your main claim. Yes, your cousin saves money, but how does that prove remote work is beneficial overall? And Sweden's policies are mentioned but never connected to any actual benefit. It's like you're checking boxes rather than building an argument.
Better: "Remote work allows employees to reduce financial strain and increase productivity. Studies show that commuting accounts for roughly 8% of workers' monthly expenses; eliminating this cost directly improves financial stability, especially for lower-income workers who spend larger proportions of their income on transport."
Here, the example directly supports the claim with a specific percentage and explains the logical connection.
Your example is so predictable that it adds no real insight. It's what every student writes.
Weak: "Technology has changed education. For example, students now use computers and the internet to learn. This is different from the past when everything was on paper."
You're not adding information here. The examiner already knows students use computers. This doesn't show depth of thinking.
Better: "Online learning platforms have democratized access to expertise. A student in rural Bangladesh can now access MIT's free OpenCourseWare or take live classes from specialized tutors worldwide, removing geographical and economic barriers that traditionally limited educational opportunity to wealthier, urban populations."
This shows you've thought deeper. You're not just naming technology; you're explaining why it matters and to whom.
Tip: Ask yourself this about every example: "Would someone who disagrees with me find this convincing?" If not, it's weak evidence that needs reworking.
Think of evidence as existing on a spectrum. Where does yours fall?
Band 6: General statement without support. "Technology is important in modern society." No example. No data. No proof.
Band 7: Clear example with basic explanation. "Technology allows people to work remotely, which saves time and money." You've added specifics, but why does it save time? For whom? How much?
Band 8: Specific, contextual example with clear reasoning. "During the COVID-19 pandemic, remote work enabled companies to maintain productivity while reducing office operating costs by 40%, simultaneously allowing working parents to balance childcare with employment. This shift particularly benefited workers in developing economies where commuting infrastructure is underdeveloped."
See the pattern? Band 6 assumes. Band 7 shows. Band 8 demonstrates.
Before you submit your essay, run every example through this checklist. If you can't answer "yes" to all five questions, your supporting examples need work.
Tip: Print this checklist and tape it to your desk. Use it for every essay you practice. In three weeks, checking evidence becomes automatic.
Let's take a real IELTS Writing Task 2 prompt and see how weak evidence appears and how to fix it:
"Some people believe that the best way to reduce crime is through education and community programs. Others believe that stricter punishments are more effective. Discuss both views and give your own opinion."
Here's a Band 6 response:
Weak: "Education is a good way to reduce crime. If people get better education, they won't commit crimes because they have better opportunities. Schools teach people right from wrong. Community programs also help because they keep young people busy."
Problems? It's vague ("better opportunities"), unsupported ("schools teach right from wrong" is assumed), and generic ("keep young people busy").
Now here's Band 8 evidence for the same position:
Better: "Education addresses the root causes of crime by expanding economic opportunity. According to the World Bank, countries that increased secondary school enrollment by 10% saw corresponding drops in youth crime rates by 12-15% within five years. This happens because education increases earning potential. A worker with a vocational certificate earns 30-50% more than someone with no qualification, making legitimate employment financially viable rather than criminal activity. Community literacy programs in Medellín reduced gang recruitment in disadvantaged neighborhoods by 23%, as participants develop conflict resolution skills and stronger social connections."
What changed? Specific numbers (10%, 12-15%, 30-50%, 23%). Named sources (World Bank, Medellín). Clear causal logic (more education equals more income equals less incentive to commit crime). Real examples. The examiner doesn't have to guess what you mean.
You don't need to rewrite everything. Sometimes one small change lifts weak evidence into strong territory.
Correction 1: Add a number or percentage.
Weak: "Many people benefit from flexible working arrangements."
Stronger: "According to a 2024 Gallup survey, 78% of remote workers report higher job satisfaction and 45% experience reduced burnout compared to office-based counterparts."
Correction 2: Replace abstract terms with concrete ones.
Weak: "Social media allows people to stay connected."
Stronger: "A grandmother in Dublin can video call her grandchildren in Australia weekly at zero cost, maintaining emotional bonds that geographical distance once severed."
Correction 3: Add the mechanism—explain why or how it works.
Weak: "Exercise improves mental health."
Stronger: "Physical activity triggers the release of endorphins and serotonin, neurochemicals that directly reduce symptoms of depression and anxiety. A 30-minute run produces the same neurochemical profile as a low-dose antidepressant for most people."
These three corrections alone move you from Band 6/7 to Band 7/8 on most essays.
You've written your essay. You have 10 minutes left. What do you look for?
Read each body paragraph and highlight every example or supporting statement. For each one, ask: "Is this specific enough that a stranger would understand exactly what I mean?" If the answer is even slightly "maybe," it's weak. Rewrite it.
Second pass: read every sentence with your main argument and the sentence immediately following it. If that next sentence is still vague or doesn't explain "why," your evidence isn't doing its job. Add one more sentence explaining the mechanism or why it matters.
Third pass: hunt for red flag phrases. They often signal weak evidence: "many people," "some studies," "it is known that," "people think," "generally," "usually." These are vague placeholders. Replace them with specifics or remove them entirely.
Tip: Set a timer for 5 minutes. In that time, do only the evidence check. Don't worry about grammar or vocabulary yet. Weak evidence kills more essays than grammatical mistakes. Our IELTS writing checker can also flag weak evidence patterns instantly.
Band 8 students don't invent examples on exam day. They've built a mental library of specific, credible examples they can deploy across different topics. You should do the same.
Create a document. Write down five strong, specific examples you've encountered recently: a statistic from a news article, a case study from a book, a policy you read about, a personal observation with numbers attached, a historical event with specific outcomes. For each one, write it out in one strong sentence with all specifics included.
Over two months of practice, you'll accumulate 40-50 high-quality examples. In the exam, you won't need to use them verbatim, but they'll inform your thinking. You'll instinctively reach for specificity because you've trained your brain to do so.
This is how Band 8 students think. They don't grab the first example that comes to mind. They choose examples precisely because those examples have substance.
Here's how to integrate evidence checking into your actual practice routine. Don't just read through this. Actually do it next time you write an essay.
Write your essay first without stopping to check. When you finish, spend the first 3 minutes reading for structure and flow. Spend the next 5 minutes on evidence only. Go through each body paragraph and write in the margin next to every example: S (specific), N (needs work), or D (developed). Only examples marked S are ready.
For anything marked N or D, ask yourself: What number, name, or concrete detail could I add? What logical connection am I asking the reader to make? How would a skeptical person challenge this example? Answer those questions right there on your draft, then rewrite the sentence if you have time.
This takes practice, but after five essays, you'll do it automatically as you write, not as a final check.
Strong evidence doesn't exist in isolation. It works because your overall argument is clear. If you're working on other areas of IELTS Writing Task 2, check out our guide on building stronger arguments to see how to structure claims so your evidence lands harder.
And when it's time to wrap up your essay, checking your conclusion is just as important as checking your evidence. A strong conclusion reminds the examiner of your best examples, which reinforces your argument.
