Most candidates know they need to hit Band 7 (or 6.5, or 7.5). Far fewer know what those numbers actually represent. If you want the whole picture first, we have a plain-English guide to what every IELTS band level means across all four skills — this post narrows in on writing.
The writing band scale is not a single score for “good English.” It is a profile across four criteria. A clear essay with weak grammar can land differently from a grammatically accurate essay that barely answers the question. That is why two essays can feel similar to a candidate but receive different bands.
The four criteria
IELTS writing is scored against four criteria, each on a 0–9 scale. Your overall band is the average of the four.
- Task Response — does your essay answer the question?
- Coherence and Cohesion — does it read like one connected argument?
- Lexical Resource — vocabulary range and accuracy.
- Grammatical Range and Accuracy — sentence structures and correctness.
For Task 1 Academic, Task Response becomes Task Achievement, but the principle is similar: did you do the task fully, clearly, and accurately?
What Band 6 usually looks like
Band 6 writing often communicates the main idea, but the control is uneven. The essay may answer the question in a general way, yet parts are underdeveloped or slightly off-topic. Paragraphing may exist, but links between ideas can feel mechanical. Vocabulary is usually adequate, with some useful range, but word choice errors are still noticeable. Grammar may include a mix of simple and complex sentences, but mistakes sometimes affect clarity.
In plain English: the examiner can follow you, but your writing still feels risky.
What Band 7 usually looks like
Band 7 writing is more controlled. The position is clear, main ideas are developed, and paragraphing helps the reader move through the argument. Vocabulary is flexible enough to express precise meaning, even if there are occasional slips. Grammar shows a range of structures, and errors do not usually block understanding.
Band 7 does not mean perfect. It means the writing is clear, relevant, organised, and mostly accurate under exam conditions.
Why most candidates plateau at 6.5
The common problem is imbalance. A candidate might have good vocabulary but weak paragraph logic. Another might write accurate sentences but never develop examples deeply enough. Many 6.5 essays also use memorised linking phrases instead of real connections between ideas.
The fastest way to move is not to “write more essays” blindly. It is to find which criterion is holding the essay down and practise that specific skill.
How to move up a band
Start with diagnosis. After each essay, ask:
- Did I answer every part of the prompt?
- Can a reader summarise my position after the introduction?
- Does each body paragraph have one clear main idea?
- Are my examples specific enough to prove the point?
- Did I use any words that sound impressive but are slightly wrong?
- Are grammar mistakes repeated, or just occasional slips?
Then rewrite one part of the essay. Do not always write a full new essay. Sometimes the best practice is rewriting one weak body paragraph, improving one introduction, or replacing vague examples with concrete ones.
Use the scale as a practice map
Most candidates do not plateau because they are lazy. They plateau because their practice loop is too broad. They write, read a band estimate, feel bad, and move on. The improvement happens when feedback turns into a small next action.
If Task Response is weak, practise planning and example development. If Coherence is weak, practise paragraph structure. If Lexical Resource is weak, practise precise word choice in context. If Grammar is weak, practise the sentence patterns you actually need for IELTS arguments.
That is the real use of the band scale: not as a label, but as a map for what to fix next.
Where to go next
The descriptors stay abstract until you watch them applied to a real essay.
Each Task 2 format guide gives a full model essay and then names what caps that particular format at band 6, which is the quickest way to turn a phrase like “develops main ideas” into something you can actually do on Saturday morning. Start with the format you are weakest on: opinion essays, discussion essays, advantages and disadvantages, problem and solution, or two-part questions. If you are not sure which formats exist or which themes keep coming back, Task 2 topics and formats covers both.
Task 1 is marked on the same four criteria with Task Response renamed, and its guides go one step further: the line graph guide sets a band 6 answer beside a band 7 answer to the same question and names the six differences between them. If you have not looked at Task 1 seriously yet, IELTS Writing Task 1 explained covers the format, the timing and the mistakes that cap the band.
Two things are worth settling before you build a study plan around any of this. What band score you actually need, because most requirements carry a per-skill minimum that can fail an application your overall average passes. And how long 1.5 bands takes, which is an honest answer rather than an encouraging one.

Frequently asked questions
- What are the four IELTS writing criteria?
- Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each is scored on the same 0 to 9 scale. In Academic Task 1, Task Response is called Task Achievement, but the principle is the same: did you do the task fully, clearly and accurately.
- How is the IELTS writing band calculated?
- Your writing band is the average of the four criteria. That is why two essays can feel similar to the candidate and receive different bands: a clear essay with weak grammar and a grammatically accurate essay that barely answers the question produce very different profiles.
- What is the difference between band 6 and band 7 in IELTS writing?
- Band 6 usually communicates the main idea with uneven control: parts are underdeveloped, links between ideas feel mechanical, and word choice errors are noticeable. Band 7 is more controlled, with a clear position, developed main ideas, paragraphing that helps the reader, and errors that do not usually block understanding.
- Does band 7 writing have to be error-free?
- No. Band 7 means the writing is clear, relevant, organised and mostly accurate under exam conditions. Occasional slips in vocabulary and a range of structures with some errors are consistent with it, as long as they do not stop the reader following you.
- Why am I stuck at 6.5 in IELTS writing?
- The usual cause is imbalance rather than overall weakness. One candidate has good vocabulary and weak paragraph logic, another writes accurate sentences but never develops examples deeply enough. Many 6.5 essays also use memorised linking phrases in place of real connections between ideas.
- How do I move up a band in IELTS writing?
- Start with diagnosis rather than volume. Writing more essays blindly practises whatever you already do. Find which of the four criteria is capping the essay, then rewrite one part that targets it, which is often more useful than producing a whole new essay.
