IELTS Grammar for Band 7+: Complex Structures That Examiners Want to See

Grammatical Range and Accuracy (GRA) is worth 25% of your IELTS Writing and Speaking band score. To achieve Band 7+, you need to demonstrate IELTS grammar structures at advanced level — complex sentences with minimal errors. This does not mean using every grammar structure you know; it means using a variety of structures correctly and naturally. Pair this guide with our free AI IELTS grammar feedback tool to get instant corrections on your actual writing.

What Band 7 Grammar Looks Like vs Band 5

Band Level	Grammar Description	Example
Band 5	Simple sentences dominate. Frequent errors in complex structures.	Many people think technology is good. It helps us in daily life.
Band 6	Mix of simple and complex. Some errors with complex structures.	Although technology has benefits, it can also cause problems for society.
Band 7	A variety of complex structures used with general accuracy.	While technology undeniably brings economic benefits, its social implications warrant careful consideration.
Band 8	Wide range of structures. Most sentences error-free.	Not only has technology transformed economies, but it has also fundamentally altered the way individuals interact.
Band 9	Full flexibility. Rare minor slips only.	What cannot be disputed is that technology’s influence, however far-reaching, demands an equally sophisticated policy response.

5 Essential Grammar Structures for Band 7+

1. Conditionals (All Types)

Examiners expect to see a range of conditional forms, not just “If + present simple + will”.

Type	Structure	IELTS Example
Zero conditional	If + present, present	If global temperatures rise, sea levels increase.
First conditional	If + present, will + base	If governments invest in renewables, emissions will fall.
Second conditional	If + past simple, would + base	If education were free globally, inequality would decrease significantly.
Third conditional	If + past perfect, would have + pp	If stricter regulations had been imposed earlier, the financial crisis would have been avoided.
Mixed conditional	If + past perfect, would + base	If better policies had been adopted, the situation would be different today.

2. Relative Clauses (Defining and Non-defining)

Defining: “Individuals who rely on social media for news are more susceptible to misinformation.”
Non-defining: “Social media, which has transformed communication globally, also presents significant risks.”

Note: Non-defining relative clauses (with commas) are a reliable Band 7+ signal and are rarely used at Band 5–6.

3. Passive Voice

The passive voice increases academic register and allows sentence variety. Use it to focus on the action rather than the agent.

Active	Passive (Band 7+ version)
Governments should implement this policy.	This policy should be implemented by governments.
Technology has changed education.	Education has been fundamentally transformed by technological advances.
They conducted the research in 2020.	The research was conducted in 2020.

4. Cleft Sentences (It is… that / What… is)

Cleft sentences add emphasis and are a clear Band 7–8 marker.

• “It is education that plays the most significant role in reducing inequality.”
• “What concerns many experts is the long-term impact of artificial intelligence on employment.”
• “What cannot be denied is that climate change poses an existential threat.”

5. Nominalization

Nominalization — converting verbs and adjectives into nouns — is a core feature of academic English and a reliable Band 7+ signal.

Verb/Adjective	Nominalized form	IELTS Sentence
to develop	development	The rapid development of AI has raised ethical questions.
to increase	an increase	There has been a significant increase in urban migration.
important	importance	The importance of education cannot be overstated.
to depend on	dependence	Over-dependence on technology risks eroding critical thinking skills.

Most Common IELTS Grammar Errors

Error	Incorrect Example	Correct Version
Missing article	Education is important factor.	Education is an important factor.
Wrong tense sequence	If more people recycle, pollution decreased.	If more people recycled, pollution would decrease.
Subject-verb agreement	The number of students are increasing.	The number of students is increasing.
Misused relative pronoun	The country which population is growing.	The country whose population is growing.
Overusing “also”	It also has many benefits. It is also important.	Furthermore, it offers significant benefits.

Frequently Asked Questions

Does using complex grammar guarantee Band 7?

No. Accuracy is equally important. A sentence with a complex structure but grammatical errors scores lower than a simple sentence used correctly. Aim for variety and accuracy.

Should I use formal or informal grammar in IELTS Writing?

Always formal/academic register for Writing Task 2. Avoid contractions (don’t → do not), avoid phrasal verbs where possible, and use nominalization over informal verb phrases.
