The Real Difference Between Band 6 and Band 7 Grammar in IELTS
It's not about avoiding mistakes — it's about demonstrating range. Here's exactly what IELTS examiners look for in GRA at Band 7.
Most IELTS candidates approach grammar the same way they approached it in school: avoid mistakes. Don't use the wrong tense. Don't forget subject-verb agreement. Don't write run-on sentences.
That approach will get you to Band 6. To reach Band 7, you need a different one.
What the GRA Descriptor Actually Says
The official Band 7 descriptor for Grammatical Range and Accuracy reads: 'Uses a variety of complex structures with frequent error-free sentences.' Two things stand out: *variety* and *error-free sentences* — not error-free writing.
This is important. Band 7 does not require a perfect essay. It requires a mix of sentence types, most of which are accurate. The examiner is assessing whether you have a wide enough grammatical toolkit to express complex ideas — and whether you can use that toolkit without falling apart.
What 'Variety of Complex Structures' Actually Means
Complex structures does not mean long sentences. It means sentences that combine ideas in different ways. Here are the structures that appear most reliably in Band 7 essays:
Relative clauses
✗ Band 6 (two simple sentences)
Governments should invest in renewable energy. This will reduce carbon emissions.
✓ Band 7 (relative clause integrating ideas)
Governments, which bear direct responsibility for long-term energy policy, should invest in renewable infrastructure that can meaningfully reduce carbon emissions.
Participle phrases
✗ Band 6
Many teenagers use social media. They experience higher levels of anxiety.
✓ Band 7
Many teenagers who spend excessive time on social media report elevated levels of anxiety, suggesting a correlation that warrants further research.
Passive voice (used selectively)
Passive voice is not wrong — it is a tool. Use it when the action matters more than the actor, or when you want to vary your sentence openings. 'The policy was introduced in 2018' focuses on the policy. 'The government introduced the policy in 2018' focuses on the government. Choose deliberately.
Conditionals
Third conditionals and mixed conditionals signal advanced grammatical control. 'Were governments to prioritise public transport, urban congestion could be reduced significantly within a decade' is a construction that appears rarely in Band 6 essays.
The Accuracy Trap
Here is a counterintuitive truth: some Band 6 essays are more accurate than Band 7 essays. How? Because accuracy is easier to achieve when you only use structures you are comfortable with.
A candidate who writes short, simple sentences with no errors will not reach Band 7 on GRA — not because they made mistakes, but because they demonstrated limited range. The examiner cannot give credit for structures that were never attempted.
Watch out
Writing simple sentences to avoid errors is one of the most common reasons candidates plateau at Band 6. The descriptor explicitly rewards range — and range means attempting structures beyond your comfort zone.
How to Build GRA Systematically
The most efficient way to improve GRA is not to memorise grammar rules — it is to expand your sentence repertoire deliberately. Treat it like vocabulary: learn specific structures, practise them in isolation, then deploy them in essays.
- 1Pick one structure per week (relative clause, participle phrase, conditional, etc.)
- 2Write 10 standalone sentences using that structure on different topics
- 3In your next essay, consciously use that structure at least twice
- 4After feedback, check whether those sentences were accurate and natural
- 5Move to the next structure the following week
Within six weeks you will have a working repertoire of six structures you can use reliably. That is more than enough for Band 7 GRA.
A Quick Diagnostic
Take your most recent essay and highlight every sentence type. If more than 70% follow the same Subject-Verb-Object pattern, GRA is your score bottleneck. If you see genuine variety but frequent errors, accuracy is the issue. They require different interventions.
Tip
Examiners read hundreds of essays per week. A single well-constructed relative clause or participle phrase stands out immediately. You do not need to overhaul your entire writing — two or three ambitious sentences per body paragraph, used accurately, is enough to demonstrate Band 7 range.
