Why do native English speakers only get band 7 in IELTS writing?

Native English speakers get band 7 in IELTS writing because the test does not measure English. It measures whether a specific task was done to a specific set of criteria, and fluency only reaches two of the four.

That is the short answer to why native English speakers only get band 7 in IELTS writing, and it is a story told often enough on candidate forums to be worth taking seriously — a teacher, a journalist, a lawyer, someone who has written in English for a living, sits the test for a visa and comes back with a 7 or a 6.5. Those accounts are anecdotes, not data, and nobody outside the test publishes scores by first language. But the mechanism behind them is entirely visible in the public band descriptors, and it is the same mechanism that holds back candidates for whom English is a second language.

Two criteria measure the English. The other two measure the task.

The test measures the task, not your English

Each Writing task is marked on four criteria, weighted equally: Task Response (Task Achievement in Task 1), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The examiner awards each criterion the band whose descriptor best fits the script, then averages them. The overall Writing band weights Task 2 twice as heavily as Task 1.

Fluency — the thing a native speaker has and a learner is working towards — lives almost entirely in the last two criteria. A native writer has range without trying, controls complex sentences without thinking about them, and rarely makes the kind of error the grammar descriptors count. On Lexical Resource and Grammatical Range and Accuracy, an 8 or 9 is realistic.

The other two criteria do not ask how good your English is. Task Response asks whether you answered this prompt, in the form it was set, with a position that is developed. Coherence and Cohesion asks whether the ideas are organised so the reader can follow a progression from start to finish. Neither of those is a language skill. They are task skills, and being a native speaker gives no head start on them.

Run the arithmetic on a typical version of the forum story. Grammar 8, vocabulary 8, Task Response 6, Coherence and Cohesion 6: the average is (8 + 8 + 6 + 6) / 4 = 7. A writer with excellent English, marked accurately, lands on exactly the score that surprised them.

Where native speakers lose Task Response

Band 7: "The main parts of the prompt are appropriately addressed. A clear and developed position is presented. Main ideas are extended and supported."

Band 8: "The prompt is appropriately and sufficiently addressed. A clear and well-developed position is presented in response to the question/s."

Both lines are written about the prompt, and that is the trap for an experienced writer. Confident writers do not answer questions as set. They answer the more interesting question next to it. In ordinary writing this is a virtue — an editor will often thank you for reframing a dull brief. In IELTS it is the single most reliable way to lose Task Response, because the examiner reads every paragraph against the words of the prompt, not against the quality of the thinking.

Take a prompt of a common shape: Some people believe that university education should be free for all students. Others think students should pay. Discuss both views and give your own opinion.

Here is the kind of opening a fluent, educated writer produces naturally:

The debate over tuition fees is usually framed as a choice between free and paid education, but that framing misses the more important question. What matters is not who pays at the point of entry but whether graduates from poorer backgrounds end up better off than they would have been. Seen that way, the real issue is the design of repayment schemes, and the most effective systems tie repayment to future income rather than charging everyone the same.

It is well written. It is also not an answer to the prompt. The task asked for two views to be discussed and an opinion on them; this opening dismisses the framing, introduces a third question, and takes a position on that instead. If the rest of the essay follows the same line, the examiner is looking at a response where the main parts of the prompt are not all addressed — one view is never discussed on its own terms, and the opinion is about repayment design rather than free versus paid. That is band 6 or 5 territory on Task Response, however polished the sentences are.

Here is the same writer answering the question as set:

Whether university should be free for all students or paid for by the students themselves turns on who benefits from a degree. Those who favour free education argue that society as a whole gains from a better-educated workforce, while those who favour fees point out that graduates capture most of the return themselves in higher earnings. I believe a degree should be free at the point of study, because the cost of deterring able students from poorer families is higher than the cost of funding those who would have paid anyway.

The ideas are no simpler. The difference is that both views are named, the opinion answers the question the prompt actually asked, and each of the next paragraphs now has an obvious job. That is what "appropriately addressed" means in practice.

The same pattern turns up in other places. A native speaker asked to what extent do you agree writes a nuanced essay that never commits to an extent. One asked about causes writes about effects, because the effects are more interesting. One asked a two-part question answers the first part thoroughly and the second part in a sentence. In every case the English is excellent and the answer is to a slightly different question. For the full wording behind this criterion, Task Achievement vs Task Response sets the Task 1 and Task 2 descriptors side by side.

Where native speakers lose Coherence and Cohesion

Both sheets read smoothly. Only one has a progression an examiner can follow.

Band 7: "Information and ideas are logically organised, and there is a clear progression throughout the response. A range of cohesive devices including reference and substitution is used flexibly but with some inaccuracies or some over/under use."

Band 8: "The message can be followed with ease. Information and ideas are logically sequenced, and cohesion is well managed."

Native writing has its own rhythm, and that rhythm is often looser than the descriptor wants. A fluent writer thinks while writing: a paragraph opens on one idea, picks up a related point halfway through, circles back with a qualification, and ends somewhere slightly different from where it started. Read aloud, it sounds natural. Read against the Coherence and Cohesion descriptor, it is a paragraph whose central topic is hard to state and whose place in the overall progression is unclear.

The descriptor asks for progression throughout the response. In practice an examiner wants to be able to say what each paragraph is for and why it comes where it does. An essay that reads like a thoughtful conversation — digressions, asides, a counterpoint raised and then dropped — makes that hard, even when every sentence is linked smoothly to the one before it.

There is an irony here. Native speakers are usually very good at the cohesion half of the criterion. They use reference and substitution — this, such a policy, the latter, doing so — without being taught, which is precisely the range of devices band 7 names. What they lose is the coherence half: the overall organisation. Learners tend to have the opposite profile, with a rigid structure held together by mechanical connectors such as Firstly and Moreover. Both can end up at 6 on the same criterion, for opposite reasons.

A smaller version of the same problem sits in Lexical Resource. Band 7 notes "an awareness of style and collocation is evident, though inappropriacies occur." Native writers occasionally reach for a register that suits a column or an email — a casual idiom, a rhetorical question, a dry joke — in an essay that the task frames as formal. It rarely costs much, but it is one reason a native writer's vocabulary is not automatically a 9.

What this means if English is not your first language

The useful lesson for every other candidate is the inverse of the native speaker's surprise. If excellent English on its own lands at 7, then improving your English is not the fastest route to 7 either. Vocabulary and grammar move slowly; they track your level in the language and change over months. Task Response and the organisational half of Coherence and Cohesion depend on decisions taken in the five minutes before you write, and those can change within a week.

Put simply: stop writing essays and start answering tasks. In practical terms:

1. Underline the instruction words before planning. Discuss both views, to what extent, what are the causes, do the advantages outweigh. Each one specifies what a complete answer must contain. Write your opinion sentence so that it uses the prompt's own question, not your reframing of it.
2. Give each body paragraph one job and name it in the first sentence. If you cannot state a paragraph's job in five words, it has more than one, and the progression will blur.
3. Develop, do not add. Band 7 asks for main ideas that are "extended and supported". One idea carried two steps — a reason, then a consequence or a limit — beats three ideas each stated once.
4. Check against the prompt, not against your English. After writing, read only the prompt and your topic sentences. If the topic sentences on their own do not answer the prompt, the essay does not either.

None of this asks for a word you do not already know. Candidates who have written correct, fluent English and still sit at 6.5 usually find the gap here rather than in the language — the same split that no grammar mistakes but still band 6.5 works through criterion by criterion. A dedicated piece on what "partially addresses the task" looks like in a real essay is coming to this series next.

Check which criterion is holding your essay

The hardest part of all this is that a fluent writer cannot see it from the inside. An essay that reframes the question reads, to its author, as a better answer, and a paragraph that wanders reads as natural. The four-criterion split only becomes visible when someone marks the script against the descriptors rather than against how good it sounds.

If the result shows Lexical Resource and Grammatical Range and Accuracy well above the other two, you have the native speaker's profile, whatever your first language, and the fixes above are the right place to start.

FAQ

Why do native English speakers only get band 7 in IELTS writing?

Because two of the four criteria, Task Response and Coherence and Cohesion, measure how the task was done rather than how good the English is. A native speaker can score 8 or 9 on vocabulary and grammar and 6 on the other two, which averages to 7.

Is it common for native speakers to fail to get band 8 or 9 in writing?

It is commonly reported by candidates, but no official figures by first language are published, so there is no reliable way to say how common it is. What can be said is that nothing in the descriptors gives a native speaker an advantage on Task Response or on organisation.

Do examiners mark native speakers differently?

No. Every script is marked against the same band descriptors, and nothing in them refers to the candidate's first language. A native speaker's essay is matched to the same wording as anyone else's.

What is the most common mistake fluent writers make in IELTS Task 2?

Answering a better question than the one asked. Reframing the prompt, taking a position on a related issue, or giving a nuanced answer that never commits to an extent all reduce Task Response, regardless of the quality of the writing.

If my English is already good, how do I get from 7 to 8?

Work on Task Response and Coherence and Cohesion first. Band 8 asks for a "well-developed position" and ideas that are "logically sequenced", so plan the answer to the prompt's exact question, give each paragraph a single job, and extend each main idea rather than adding more of them.
