IELTS Writing band scores
IELTS Writing band 6 vs band 7: the real difference
The half-band that stands between you and most visa, university and registration targets is rarely about ideas. It is about error control and range. Here is exactly what changes between band 6 and band 7 across the four criteria, with a band 6 sentence rewritten to a band 7 one.
In short
- Band 6 communicates the message but with noticeable, recurring errors and a limited range of vocabulary and structures.
- Band 7 is clear and well organised, uses some less common vocabulary accurately, and produces frequent error-free sentences.
- The move from 6 to 7 is about control and range across all four criteria, not adding new ideas.
What the two bands actually describe
Both scores are read against the same four IELTS Writing criteria, each worth 25%: Task Response (Task Achievement on Task 1), Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. A band 6 and a band 7 essay often share the same plan and the same ideas. What separates them is how cleanly and how flexibly those ideas are expressed.
Band 6. The message gets through. The essay addresses the task, organises information with some logic, and uses an adequate range of vocabulary. But errors are noticeable: articles, prepositions, verb tenses and word forms slip every few lines, and the same simple sentence patterns repeat. Linking words may be mechanical or overused. The reader never gets lost, but the writing visibly strains.
Band 7. The essay is clear and logically organised, with ideas presented and supported in full. It uses a range of complex structures and some less common vocabulary accurately, with awareness of collocation. Crucially, it produces frequent error-free sentences. Mistakes still appear, but they no longer interrupt the reader, and the range of language is wider and more controlled.
Criterion by criterion: where the half-band is won
The contrast is easiest to see when each criterion is read side by side. None of these changes requires harder ideas, only tighter execution.
| Criterion | Band 6 | Band 7 |
|---|---|---|
| Task Response | Addresses the task but ideas are not always developed or fully relevant | Answers every part with a clear position and ideas extended and supported |
| Coherence & Cohesion | Some logic, but linking words are mechanical, overused or faulty; paragraphing uneven | Logical progression, one clear central idea per paragraph, cohesion used flexibly |
| Lexical Resource | Adequate but repetitive; errors in word choice, form and spelling are noticeable | Some less common vocabulary used accurately, with awareness of collocation |
| Grammatical Range & Accuracy | Mix of simple and complex forms, but errors recur every few sentences | A variety of complex structures with frequent error-free sentences |
Read down the band 6 column and the pattern is the same on every row: meaning is communicated, but range is limited and errors are noticeable. The band 7 column is not cleverer, it is cleaner and more flexible.
A band 6 sentence rewritten to band 7
The difference is clearest in a single rewrite. Both sentences make the same point on a Task 2 prompt about whether governments should fund public transport. Watch what changes, and what stays the same.
Band 6 version. "Nowadays many people is using the car for go to work, so the traffic is very bad and the goverment should make more bus and train because it is good for environment and reduce the pollution."
This communicates the idea, but the examiner sees a run-on sentence, a subject-verb error ("people is"), an infinitive error ("for go"), a missing article and plural ("more bus"), a spelling error ("goverment"), and only basic vocabulary. Meaning survives, range and accuracy do not. That is a textbook band 6.
Band 7 version. "As more commuters now rely on private cars, congestion has worsened in most cities. Governments should therefore invest in frequent bus and rail services, which would both cut harmful emissions and ease pressure on the roads."
The idea is unchanged. What moved is the execution: two controlled sentences instead of one run-on, accurate subject-verb agreement, a less common but correct phrase ("rely on private cars", "ease pressure on the roads"), a relative clause used naturally, and no errors. This is the kind of line-level shift a correction targets, sentence by sentence, rather than a single overall band.
Band 6 vs band 7: common questions
What is the difference between IELTS Writing band 6 and band 7?+
Band 6 communicates the message but with noticeable errors and a limited range of vocabulary and structures. Band 7 is clear and well organised, uses some less common vocabulary accurately, and produces frequent error-free sentences. The jump is about control and range, not new ideas.
Why am I stuck on band 6 in IELTS Writing?+
Most band 6 essays answer the question but repeat the same simple structures, reuse basic words, and carry small errors in articles, tenses and prepositions that recur every few lines. Examiners see meaning is communicated but accuracy and range are limited, which holds you at 6.
How many error-free sentences does band 7 need?+
The official descriptor for Grammatical Range and Accuracy at band 7 expects frequent error-free sentences. You do not need perfection. A band 7 script still contains some mistakes, but a clear majority of sentences are clean and a good range of complex structures is used.
Does better vocabulary alone move me from 6 to 7?+
No. Lexical Resource is only one of four criteria. Forcing in rare words that are used wrongly can lower your score. Band 7 needs less common vocabulary used accurately, plus clearer organisation, frequent error-free sentences and a fully developed answer across all four criteria.
How can I tell if my writing is a 6 or a 7?+
Self-assessment is unreliable because the gap is small and habitual errors feel normal to the writer. A trained assessor marking against the official descriptors can show which criterion is capping you and point to the exact lines, which is what a correction provides.
