10 grammar structures for IELTS Band 7 Writing
The structures examiners reward at Band 7 — and the errors that cap candidates at 6.5.
Grammatical Range and Accuracy (GRA) is one of the four equally weighted criteria in IELTS Academic and General Training Writing. Band 7 descriptors require 'a variety of complex structures' used 'with some errors' — meaning examiners want both breadth and precision. Understanding what that looks like in practice is the fastest way to improve your Writing score.
The GRA principle: accuracy first, then range
A long, complex sentence that contains a grammatical error scores worse than a correct simple sentence. Accuracy is the foundation. Once you can write simply and correctly, you add structural variety — not the other way around.
Many candidates aim for impressive language before they have secured basic accuracy. The result is a response full of ambitious attempts that undermine the score. The more effective strategy is to master a small set of structures you can deploy reliably, then extend your range from that secure base.
10 structures examiners reward at Band 7
Each structure below includes a pattern and a sentence you could use or adapt in Task 1 or Task 2. Study the pattern before the example — understanding the template is what makes a structure transferable.
| Structure | Pattern | Example |
|---|---|---|
| Concession | Although [conceded point], [main claim]. | Although renewable energy requires significant upfront investment, it reduces long-term costs considerably. |
| Weighted contrast | While [partial truth], [stronger counter-point]. | While job creation matters, the environmental consequences of rapid industrialisation matter more. |
| Relative + result | [Noun clause], which means that [consequence]. | Remote working has become the norm for many professionals, which means that urban transport demand has fallen sharply. |
| Second conditional | If [unreal condition] were [state], [subject] would [outcome]. | If public transport were both affordable and reliable, fewer commuters would rely on private vehicles. |
| Emphatic addition | Not only [first point], but [subject] also [second point]. | Not only does regular exercise improve physical health, but it also reduces anxiety and depression. |
| Cleft sentence | It is [emphasised element] that [rest of clause]. | It is access to quality education that determines long-term economic mobility more than any other factor. |
| Reason framing | One reason for [topic] is that [explanation]. | One reason for the rise in childhood obesity is that processed food has become cheaper relative to fresh produce. |
| Semicolon + result | [Independent clause]; consequently, [result]. | Urban populations have grown rapidly over the past two decades; consequently, housing supply has failed to keep pace. |
| Means → outcome | By [gerund phrase], [subject] can [result]. | By investing in teacher training, governments can raise educational standards without building new schools. |
| Inverted conditional | Were it not for [cause], [subject] would [outcome]. | Were it not for international aid, the region would have faced a far more severe humanitarian crisis. |
How to use these structures strategically
You do not need all ten in a single essay. A Task 2 response of 280 words has room for roughly four to six distinct structures alongside straightforward sentences. The goal is visible variety, not a showcase of everything you know.
Select two or three structures from the table above that feel natural to you. Practise writing three to five sentences with each one until the pattern is automatic. When a structure feels controlled, add another. This is the approach recommended in the Band 7 Writing Playbook, and it mirrors how examiners actually read: they notice patterns of accuracy or error, not individual clever sentences.
Prioritise structures that fit your argument type
- Discussing causes or reasons: use reason framing and means→outcome.
- Comparing or evaluating views: use concession, weighted contrast, and cleft sentences.
- Describing trends or changes: use relative+result and semicolon+result.
- Hypothetical or policy arguments: use second conditional and inverted conditional.
Five error patterns that cap GRA at 6.5
These five errors appear across the majority of scripts that stall at Band 6 to 6.5. Each one signals limited control to an examiner, regardless of how sophisticated the vocabulary is.
- 1Subject–verb agreement. Error: 'The number of students are increasing.' Fix: The subject is 'number' (singular), so write 'The number of students is increasing.' Treat collective nouns and noun phrases carefully — always identify the true head noun.
- 2Article errors (a / an / the). Error: 'Government should provide education to public.' Fix: 'The government should provide education to the public.' Use 'the' for specific or previously mentioned nouns, and omit or use 'a/an' for general first reference. Articles are the single most common error in non-native writing.
- 3Run-on sentences (comma splices). Error: 'Technology improves productivity, it also creates new jobs.' Fix: Split into two sentences, or join with a conjunction: '…productivity, and it also creates new jobs.' A comma alone cannot join two independent clauses.
- 4Double linkers. Error: 'Although the policy is well-intentioned, but it fails in practice.' Fix: Choose one connective — 'Although' or 'but', not both. This is a direct cap on GRA because it signals a misunderstanding of how subordination works.
- 5Tense drift. Error: Switching between past and present tense within a single argument without reason. Fix: Decide your primary tense before writing and stick to it. Use past tense for historical evidence; use present simple for general truths and current trends.
Build a personal error log
Generic grammar revision is far less efficient than targeting your own repeat errors. After each practice essay, note every correction your teacher or a grammar tool identifies. Group them by type. Within two to three weeks, a pattern will emerge — most candidates have two or three dominant error types, not ten.
Before submitting any practice essay, re-read it once looking only for your top two error types. This single-focus proofreading is more reliable than trying to check everything simultaneously.
Grammatical range and accuracy is assessed on the whole response. A few impressive structures do not compensate for frequent basic errors.— IELTS Writing Band Descriptors (public version)
A note on complexity and length
Longer sentences are not inherently better. A sentence that runs to four clauses and contains a subject–verb agreement error in the third clause will reduce your GRA score. Aim for sentences of one to two clauses that are completely accurate, then layer in the complex structures from the table above where they add clarity or precision to your argument — not merely length.
Master four or five structures you can control perfectly. Attempting ten you cannot control is the most reliable way to stay at Band 6.5.
Frequently asked
What grammar do I need for IELTS Band 7?
Band 7 requires a variety of complex grammatical structures used with reasonable accuracy — meaning a mix of simple, compound, and complex sentences, with most of them correct. Examiners look for structures such as concessive clauses (Although…), relative clauses (…, which means that…), conditionals, and cleft sentences, alongside consistently accurate article and verb usage.
Are complex sentences required for Band 7?
Yes, but not exclusively. Band 7 descriptors specify 'a variety of complex structures', which means examiners expect to see complex sentences present — not that every sentence must be complex. A response that mixes accurate simple sentences with well-controlled complex structures scores better than one composed entirely of flawed attempts at complexity.
What are the most common grammar mistakes in IELTS Writing?
The five most common errors that cap candidates at Band 6 to 6.5 are: subject–verb agreement errors, article mistakes (a/an/the), comma splices (joining independent clauses with a comma), double linkers (using 'Although…but…' together), and tense drift within a single argument. Eliminating these four categories alone can move a candidate from 6.5 to 7.
Is it better to write simple or complex sentences in IELTS Writing?
It depends on your current accuracy level. If your complex sentences frequently contain errors, accurate simple sentences score higher. Once you can write simple sentences with full accuracy, you should introduce complexity — because Band 7 requires range, not just correctness. The practical answer is: write simple where unsure, complex where confident.
How many different grammar structures do I need in one essay?
There is no fixed number, but visible variety across a 280-word Task 2 response typically means four to six distinct structural patterns. You do not need all ten structures from this guide in a single essay. Two or three that you control confidently will demonstrate range more effectively than six that contain errors.
