A 6.5 in IELTS Writing doesn't tell you what to fix. It is built from two tasks and eight criterion scores, and the gap to 7 can sit in any of them. In the AI-scored Task 2 essays we looked at, the gap was most often in language: grammar that stays accurate in complex sentences, and words that fit exactly. Your own weakest criterion may differ, so the first step is to find it.
What a 6.5 in Writing really means
IELTS marks each Writing task separately against four criteria of equal weight: Task Achievement in Task 1 or Task Response in Task 2, then Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The task score is the average of the four. The two tasks are then combined: "Task 1 is worth a third of your overall mark for Writing. Task 2 is worth two thirds."
So a Writing 6.5 is not one measurement. A single Task 2 essay scored 7, 7, 6 and 6 averages 6.5 on its own, and your Task 1 then pulls the final band up or down.
The official descriptors add one strict rule: "A script must fully fit the positive features of the descriptor at a particular level." A criterion reaches 7 only when all its band 7 features are there. One strong paragraph is not enough if the next one breaks down.
Which criteria hold 6.5 Task 2 essays back
We looked at Task 2 essays scored 6.5 by the GoPrep AI examiner. In 78% of them, at least one criterion was already 7 or higher. The criteria left below 7 were most often the two language ones.
| Criterion | Below 7 in essays scored 6.5 | Lowest or tied lowest in essays scored 6.0 to 6.5 |
|---|---|---|
| Lexical Resource | 91% | 60% |
| Grammatical Range and Accuracy | 87% | 82% |
| Coherence and Cohesion | 61% | 13% |
| Task Response | 39% | 21% |
Column 2: 930 essays scored 6.5. Column 3: 2,464 essays scored 6.0 or 6.5. All Task 2 answers from 28 July to 26 September 2026. Ties count for each tied criterion, so shares overlap.
The most common single pattern, Task Response and Coherence and Cohesion at 7+ with both language criteria below 7, covered only 29% of 6.5 essays. "Below 7" can mean 6.5 (the GoPrep AI examiner reports half bands for each criterion), 6 or lower. This describes our sample, not your essay, so check your own four scores.
Band 6 vs band 7: the exact wording
Here is a selection from the official Task 2 descriptors, word for word. It is not the full text, but these are the lines where band 6 and band 7 differ most.
| Criterion | Band 6 | Band 7 |
|---|---|---|
| Task Response | "The main parts of the prompt are addressed (though some may be more fully covered than others)"; "some may be insufficiently developed or may lack clarity" | "The main parts of the prompt are appropriately addressed"; "A clear and developed position is presented"; "Main ideas are extended and supported but there may be a tendency to over-generalise…" |
| Coherence and Cohesion | "cohesion within and/or between sentences may be faulty or mechanical due to misuse, overuse or omission" | "A range of cohesive devices including reference and substitution is used flexibly but with some inaccuracies or some over/under use" |
| Lexical Resource | "a rather restricted range or a lack of precision in word choice" | "sufficient to allow some flexibility and precision"; "An awareness of style and collocation is evident, though inappropriacies occur" |
| Grammatical Range and Accuracy | "Examples of more complex structures are not marked by the same level of accuracy as in simple structures" | "A variety of complex structures is used with some flexibility and accuracy"; "error-free sentences are frequent" |
Read each row as one change:
- Task Response: every main part of the question answered, a clear position, and each main idea extended with a reason and an example or consequence.
- Coherence and Cohesion: linking that shows the right relationship, including reference and substitution: words like this, such or these costs that point back to an idea. Starting a sentence with a linker is fine; a linker that adds no meaning is the problem. More in linking words for Task 2.
- Lexical Resource: precise words and collocations (words that naturally go together) you are sure of. Band 7 asks for "some ability to use less common and/or idiomatic items", not rare words everywhere.
- Grammatical Range and Accuracy: complex sentences you control, and "error-free sentences are frequent".
Band 7 still allows "A few errors in grammar may persist": it is not error-free writing. Bands 6, 7 and 8 with examples are in the Writing band descriptors guide.
How the fixes change between 6.5 and 7
The GoPrep AI examiner picks up to three priority fixes for each Task 2 answer. Here is how often each kind of fix was among them, in answers scored 6.0 to 6.5 and in answers scored 7.0 to 7.5.
| Priority fix | Answers at 6.0 to 6.5 | Answers at 7.0 to 7.5 |
|---|---|---|
| Subject-verb agreement | 44% | 19% |
| Run-on sentences and fragments | 17% | 7% |
| Word form | 19% | 7% |
| Word choice and collocation | 53% | 70% |
| Cohesion and reference | 42% | 58% |
2,458 answers scored 6.0 to 6.5 and 1,111 scored 7.0 to 7.5, out of 8,010 Task 2 answers with priority fixes, 28 July to 26 September 2026. The shares show how often each issue was among up to three priority fixes, not how often it occurred overall.
At 6.0 to 6.5, basic grammar still takes many of the three slots; at 7.0 to 7.5, word choice and cohesion fill them instead. A sensible order follows: basic grammar first, then precision.
What was different in essays that reached 7
We compared pairs of Task 2 essays written by the same learners on GoPrep and scored by the GoPrep AI examiner between 28 July and 26 September 2026. Each pair is a learner's first essay scored 6.0 to 6.5 in that period and their first later essay scored 7.0 to 7.5. 245 learners had such a pair. In the later essay:
- Grammatical Range and Accuracy was higher for 91% of them, and Lexical Resource for 90%.
- Task Response was higher for 75%, and Coherence and Cohesion for 76%.
- The median length was 288 words, against 274 in the earlier essay.
These were not one-criterion jumps. The data show what was different, not what caused it.
Did the 7 last? 185 of the 245 wrote another Task 2 essay afterwards. In that next essay, 88 of 185 (48%) scored 7.0 or higher again, and 61 (33%) dropped below 6.5. Scores vary from essay to essay, so treat one 7 as a good sign, not a stable level: aim for several essays in a row at 7 before your exam.
How much Task 1 counts in your Writing band
IELTS puts it plainly: Task 1 is worth a third of your Writing mark and Task 2 two thirds. The rounding of the final band isn't published, so these examples use numbers that need none. Picture it as (Task 1 + Task 2 + Task 2) ÷ 3:
- Task 1 at 8, Task 2 at 6.5: (8 + 6.5 + 6.5) ÷ 3 = 7.0.
- Task 1 at 5.5, Task 2 at 7: (5.5 + 7 + 7) ÷ 3 = 6.5.
The second candidate wrote a band 7 essay and still finished at 6.5. In Academic Task 1, the band 7 line is mostly about the overview: band 6 says "A relevant overview is attempted", band 7 says "It presents a clear overview, the data are appropriately categorised, and main trends or differences are identified". Keep 20 minutes for Task 1 and write the overview first. How it looks on a real chart is in our line graph guide.
Practice: the 6.5 to 7 paragraph edit
Here is a body paragraph with typical 6.5 habits. The question:
Many companies now allow employees to work from home. Do the advantages of this outweigh the disadvantages?
This exercise edits one paragraph about the advantages. A complete answer must also address the disadvantages and explain your overall judgement; the full essay below does that.
The paragraph
Firstly, working from home save a lot of time for employees. Moreover, they do not need to travel to the office every day, so they can use this time for other things. Furthermore, it is very good for companies, because workers are always more productive at home. This is why many people prefer this.
Find five things to change before you read on:
- one grammar error
- one claim that goes too far
- one idea that is named but not developed
- linkers that add no meaning
- a reference word that points to nothing clear
The edit
The clearest advantage of working from home is the time it saves. An employee who used to commute for an hour each way, five days a week, gains ten hours a week, which they can use for rest, exercise or childcare. Companies can benefit too: staff who are less tired from travelling may concentrate better, although this depends on having a quiet place to work. These extra hours are one reason why many employees want to keep the option.
No rare words were added: the same ideas are developed, limited and linked. The ten hours is a worked example, not a statistic.
| What changed | Criterion | Band 7 wording |
|---|---|---|
| working from home save is gone; the new sentence says the time it saves | Grammatical Range and Accuracy | "error-free sentences are frequent" |
| use this time for other things became ten hours a week for rest, exercise or childcare | Task Response | "extended and supported" |
| always more productive became may concentrate better, although… | Task Response | avoids "a tendency to over-generalise" |
| Firstly, Moreover, Furthermore went; too, which and although now show how the ideas relate | Coherence and Cohesion | "used flexibly" |
| This is why many people prefer this became These extra hours are one reason… | Coherence and Cohesion | "reference and substitution" |
| a lot of time became a figure; very good for companies became Companies can benefit | Lexical Resource | "some flexibility and precision" |
The full essay: advantages, disadvantages and a judgement
The edited paragraph in a complete answer. Written by the GoPrep team as a practice example, not an officially marked script, so we don't give it a band (about 270 words).
Many companies now allow their staff to work from home for some or all of the week. Although this arrangement has real drawbacks for teamwork and for people without a suitable place to work, I believe its advantages outweigh them for most office employees.
The clearest advantage of working from home is the time it saves. An employee who used to commute for an hour each way, five days a week, gains ten hours a week, which they can use for rest, exercise or childcare. Companies can benefit too: staff who are less tired from travelling may concentrate better, although this depends on having a quiet place to work.
The main disadvantage is the loss of everyday contact between colleagues. New employees in particular learn by watching experienced staff and asking quick questions, and this is much harder over video calls. Some people also struggle to separate work from home life, especially in a small flat with no separate room, so they may end up working longer hours rather than fewer.
However, these problems can be reduced, whereas the time saved cannot be gained in any other way. A company can ask teams to meet in person on fixed days, so that newer staff still receive support, and it can pay for equipment or shared workspaces for those who cannot work comfortably at home.
In conclusion, working from home weakens contact between colleagues and does not suit every living situation, but these drawbacks can be managed. The hours it gives back to employees are a lasting benefit, so in my view the advantages outweigh the disadvantages.
| Criterion | What to notice | Band 7 wording |
|---|---|---|
| Task Response | Both sides get a paragraph, and paragraph 4 weighs them, which is what outweigh asks for. The position is the same in the introduction and the conclusion. | "A clear and developed position is presented" |
| Coherence and Cohesion | One job per paragraph. These problems and this arrangement point back instead of stacking linkers. | "reference and substitution" |
| Lexical Resource | Plain words used exactly: everyday contact, shared workspaces, fixed days. | "some flexibility and precision" |
| Grammatical Range and Accuracy | Complex sentences under control: Although…, who used to commute, so that…, whereas…. | "A variety of complex structures" |
Three routes, depending on your weak criteria
Sort your own scores into one of three profiles. Here is how learners' first Task 2 essays scored 6.5 on GoPrep split.
| Criteria below 7 | Share of learners | Where to start |
|---|---|---|
| Language only (Lexical Resource and/or Grammatical Range and Accuracy) | 30% | Error types and word choice: the 4-week plan below as it is |
| Language and Task Response or Coherence and Cohesion | 62% | Plan each essay in 5 minutes, then the language weeks |
| Task Response or Coherence and Cohesion only | 8% | Planning, one idea per paragraph, and linking |
Each learner's first Task 2 essay scored 6.5 within 28 July to 26 September 2026. All four criteria were below 7 for 22% of learners; they are in the middle row.
If Task Response is part of your gap, the Task 2 guide has a 5-minute plan that makes you develop each idea before you write.
A 4-week plan from 6.5 to 7
A plan for one focused month, built around the most common gaps above. It covers the first month, not the whole move: in GoPrep practice data across all four skills, among skill histories starting at 6.5 that were still being practised at week 12, 29% (69 of 241) had two new tests in a row at 7.0 or higher by then (see how long it takes to improve your IELTS score). If your gap is only Task Response or Coherence and Cohesion, spend weeks 2 and 3 on planning and paragraphing instead. No plan guarantees a band; the point is to aim every essay at the criteria that are still below 7.
| Week | Focus | What you do |
|---|---|---|
| 1 | Find your gap | Write 2 timed Task 2 essays (40 minutes). List every grammar error by type: agreement, articles, word form, run-ons. Pick the 2 types that repeat most. |
| 2 | Grammar control | Write 3 essays. After each, mark every sentence with no errors, then fix your 2 error types first. Use complex structures you control: although, which, who, if. |
| 3 | Precise words and linking | Write 3 essays. Replace vague words (thing, good, a lot) with exact ones. Check each linker: keep it if it shows the right relationship; use this or such + a noun only when it clearly points back. |
| 4 | Full Writing under time | Do 2 or 3 full Writing tests: Task 1 in 20 minutes, Task 2 in 40. Check the Task 1 overview first. Compare your criterion scores with week 1. |
For word choice in week 3, Task 2 vocabulary by meaning shows which synonym fits which sentence.
FAQ
Why is my IELTS Writing stuck at 6.5?
A single Writing band doesn't show which criterion is holding you back: it combines two tasks and eight criterion scores. At this level, grammar accuracy and precise word choice are common gaps, but Task Response or Coherence and Cohesion can also be below 7, so check each criterion in your own essays.
How do I get from 6.5 to 7 in IELTS Writing?
Find the criteria below 7 and compare your writing with the band 7 wording for each: all parts of the question answered with a clear position, ideas extended and supported, flexible linking and reference, precise words, and frequent error-free sentences. Fix one error type at a time and keep Task 1 strong, because it is worth a third of your Writing mark.
Is band 7 in IELTS Writing difficult?
It depends on where you start. IELTS publishes no typical time to move from 6.5 to 7: what matters is how many criteria are below 7 and how regularly you write and get feedback on your essays.
Is 7 a good score in IELTS Writing?
Yes. On the IELTS scale, band 7 is labelled "Good": operational command of English with occasional inaccuracies. Whether it is enough depends on what your university, employer or visa requires.
