5 Grammar Patterns That Signal Band 7 Grammatical Range and Accuracy

Most advice on IELTS Grammatical Range and Accuracy repeats the criterion’s own wording back at you — “use a variety of complex structures” — without showing concrete examples of what that actually looks like in a sentence a real candidate would write. This post does the opposite: five specific, recognizable Band 7 sentence patterns that show up again and again in writing examiners mark Band 7 and above, each with a Band 6-level sentence rewritten into the pattern, so you can check your own drafts against something concrete rather than a rule.

What Does Band 7 Grammatical Range and Accuracy Actually Look Like?

It looks like five recurring patterns distributed across an essay, not concentrated in one showcase sentence: a noun clause used as the subject or object of a sentence instead of a simple noun; a conditional that goes beyond the basic “if this happens, that will happen” form; a non-defining relative clause that adds extra information without restricting what came before it; passive voice used accurately for impersonal, formal claims rather than personal opinions; and a concession or contrast connector — although, despite, even though — placed inside a sentence rather than only at the start of one, next to “but.” None of these patterns requires advanced vocabulary. What they require is restructuring a simple idea into a more complex grammatical shape while keeping it accurate, which is exactly what the official band descriptors mean by “a variety of complex structures” combined with “frequent error-free sentences.”

That’s the complete answer if this is all you need. The five patterns below, each with a direct before-and-after rewrite, show exactly how to build them into sentences you’re already trying to write.

Band 6 vs Band 7: The Same Idea, Five Different Structures

Each right-hand sentence is still something a candidate can plan in real time under exam pressure — none of them depends on rare vocabulary, only on a different grammatical shape for an idea the candidate already had.

The Five Patterns, One at a Time

1. Noun clauses as the subject or object of a sentence. Instead of starting with “many people think” or “I believe,” start the sentence with what the idea actually is: “What worries employers most is…”, “The fact that youth unemployment has risen suggests…”, “Whether this policy succeeds depends on…”. This single habit — starting a sentence with a clause instead of a simple noun — is one of the fastest ways to raise structural variety across an essay, because it can be applied to almost any opinion sentence a candidate already plans to write.
2. Conditionals beyond the first conditional. Most Task 2 essays use “if this happens, that will happen” throughout, which is grammatically correct but structurally repetitive. A second conditional (“If stricter laws were introduced, pollution would likely decrease”) or a mixed conditional (“If the government had acted sooner, the crisis would not be as severe now”) signals a wider grammatical range precisely because it’s harder to produce accurately, and examiners notice when it’s produced correctly.
3. Non-defining relative clauses. A defining relative clause (“the policy that caused the most controversy”) restricts meaning; a non-defining one, set off by commas, adds extra information to something already identified (“the policy, which was introduced in 2019, caused considerable controversy”). Using the non-defining form correctly — including the comma placement — demonstrates control that the far more common defining form doesn’t.
4. Accurate passive voice for impersonal, formal claims. Task 2 essays are meant to argue a position with some academic distance, and the passive voice is the natural grammatical tool for that distance: “it is widely believed that,” “this view has been criticized for,” “measures have been introduced to address this.” Candidates who write only in the active voice, with “I” or “people” as the subject of nearly every sentence, miss one of the clearest range signals available in discursive writing.
5. Mid-sentence concession and contrast. “But” at the start of a sentence is grammatically fine and very common at Band 5 and 6. Moving the same contrast into subordinate clauses — “although,” “despite the fact that,” “even though,” “while” — and placing it inside a single sentence rather than across two shows the examiner a more sophisticated grammatical relationship between the two ideas, not just that they disagree.

Why Range Alone Doesn’t Get You to Band 7

According to the official IELTS Writing band descriptors, jointly published and administered by the British Council, IDP: IELTS Australia, and Cambridge Assessment English, Band 7 requires using “a variety of complex structures” AND producing “frequent error-free sentences,” while Band 6 allows “a mix of simple and complex sentence forms” with errors that don’t usually block communication. The two halves of that descriptor move together: a response stuffed with ambitious subordinate clauses that are grammatically broken doesn’t score higher than a simpler, cleaner one — it can score lower, because errors in the more complex structures are still errors. The five patterns above are worth practicing specifically because they’re complex enough to demonstrate range, but structurally predictable enough to produce accurately once rehearsed, which is exactly the combination the descriptor rewards.

This is also why cramming all five patterns into one paragraph doesn’t work as well as spreading them across the essay. Examiners read the whole response before assigning a band, and a single complex sentence surrounded by ten simple ones reads as an isolated flourish rather than genuine range. Distributing at least one of these patterns into most paragraphs — the introduction, each body paragraph, and the conclusion — is what makes “variety” visible across the response as a whole, which is closer to what Band 7 Writing actually looks like in a full essay rather than in a single sentence.

Common Mistakes When Trying to Add These Patterns

Candidates who’ve just learned these patterns often make one of three mistakes under exam pressure. First, forcing a non-defining relative clause onto a noun that doesn’t need extra information, producing an awkward aside rather than a natural addition — “Pollution, which is bad, affects cities” adds nothing a simpler sentence wouldn’t say better. Second, overusing the passive voice until every sentence loses its subject, which flattens the essay’s voice rather than adding range; the passive works best for two or three impersonal claims per essay, not for every sentence in a paragraph. Third, attempting a mixed conditional with the wrong tense combination — mixing a present-tense condition with a past-tense result, for example — which turns an attempt at range into a clear accuracy error. The fix for all three is the same: practice each pattern in isolation on practice prompts before the exam, so the grammatical shape is automatic rather than something constructed sentence by sentence during the real test, when attention is split between organizing ideas and managing the forty-minute Task 2 time limit.

A Quick Way to Audit Your Own Writing

Take an essay you’ve already written and check it against four questions: Does any sentence start with a clause (“what,” “the fact that,” “whether”) instead of a simple subject? Does any conditional go beyond the basic first-conditional form? Does any relative clause add extra information with commas, rather than restricting a noun? Does any passive sentence make an impersonal, formal claim rather than just converting an active sentence for its own sake? If the honest answer to most of these is no, that’s precisely the gap between where the writing currently sits and Band 7 Grammatical Range and Accuracy — not vocabulary, not length, but the absence of these specific structural choices.

Spotting these five patterns in someone else’s writing is far easier than noticing their absence in your own, especially under exam time pressure when you’re focused on ideas rather than sentence shape. Our IELTS writing correction service has a qualified teacher mark your essay against all four official criteria, including exactly which Grammatical Range and Accuracy patterns are already working and which ones never appear, with a full band estimate delivered within 48 hours. If you want to see how this same grammatical range plays out at the next band up, Band 7 vs Band 8 walks through what changes in the sentences themselves between the two bands.
