Passive Voice in IELTS: When and How to Use It
Master passive voice in IELTS Writing and Speaking — know exactly when it raises your score and when it quietly destroys it.
Passive voice is one of those grammar structures that IELTS candidates either overuse desperately — thinking it sounds 'academic' — or avoid completely out of fear of getting it wrong. Neither approach is correct. The examiners rewarding Band 7+ grammatical range are looking for candidates who deploy passive constructions deliberately, accurately, and appropriately. That means knowing which contexts demand the passive, which ones tolerate it, and which ones punish it.
Why Passive Voice Matters for Your Band Score
The IELTS Writing band descriptors for Grammatical Range and Accuracy (GRA) specifically reward 'a wide range of structures.' Passive voice is one of the core structures examiners expect to see at Band 7 and above — but only when it appears naturally and correctly. A candidate who writes exclusively in the active voice will likely be capped around Band 6 for GRA, regardless of how accurate their sentences are. Accuracy alone is not enough; variety is the other half of the equation.
That said, passive voice is not a magic band-raiser. A sentence that is passive but awkward, or passive but inaccurate, will actively lower your score. The goal is controlled, purposeful use — not decoration.
The Four Situations Where Passive Voice Belongs in IELTS
- 1When the agent (the doer) is unknown or irrelevant — 'Over 200 factories were closed during the recession' focuses on the factories, not on who closed them.
- 2When describing processes in Task 1 — 'The mixture is heated to 80 degrees before it is filtered' is standard process language and sounds appropriately objective.
- 3When the object of the action is more important than the subject — 'The report was published in 2019' puts the report in the topic position, which is often what the sentence needs.
- 4When varying sentence structure — alternating between active and passive prevents your writing from sounding monotonous and demonstrates grammatical range.
Tip
In Task 1 process diagrams, aim for roughly 60–70% passive constructions. Sentences like 'Raw materials are transported to the facility, where they are sorted and cleaned' match the objective, technical register that process descriptions require.
Passive Structures You Should Know Cold
IELTS rewards grammatical range, which means examiners want to see more than just simple present passive. The table below lists the passive tenses most useful for IELTS Task 1 and Task 2, with examples drawn from common exam topics.
| Passive Tense | Structure | IELTS Example |
|---|---|---|
| Simple Present | is/are + past participle | The water is purified before distribution. |
| Simple Past | was/were + past participle | The law was introduced in 1998. |
| Present Perfect | has/have been + past participle | Significant progress has been made in renewable energy. |
| Future (will) | will be + past participle | The waste will be recycled at the next stage. |
| Modal Passive | should/must/can + be + past participle | Greater funding must be allocated to public healthcare. |
| Present Continuous | is/are being + past participle | New policies are being developed to address the crisis. |
Notice how modal passives — 'must be allocated,' 'should be considered,' 'can be reduced' — are particularly valuable in Task 2 argument essays. They allow you to make recommendations without sounding personally aggressive, which suits the formal academic register IELTS demands.
Band 5 vs Band 7: What the Difference Looks Like
The difference between weak and strong passive use is often not about whether the passive is used — it is about whether it is used in the right place and constructed accurately. Compare these two attempts to describe the same idea in a Task 2 essay about urban pollution.
✗ Band 5
Cars are used by people and pollution is made by factories and the air is got polluted by many things.
✓ Band 7+
Urban air quality has been significantly degraded by vehicle emissions and industrial output, both of which must be regulated more strictly by national governments.
The Band 5 example uses the passive mechanically — there is no logical reason to choose passive over active for 'cars are used by people,' since the agent (people) is stated anyway. The Band 7+ sentence uses the present perfect passive ('has been degraded') to emphasise the result over time, and the modal passive ('must be regulated') to deliver a recommendation cleanly. Every passive choice has a purpose.
The Most Common Passive Voice Mistakes in IELTS
Watch out
Never write 'by people' after a passive verb if you can simply make the sentence active. 'Mistakes are made by people in stressful situations' is weaker than 'People make mistakes in stressful situations.' Adding 'by + agent' defeats the main purpose of using the passive in the first place.
Watch out
Do not confuse past participles with simple past forms. 'The bridge was build in 1950' is a Band 4-level error. The correct form is 'was built.' Irregular past participles — built, written, made, given, taken, shown — must be memorised. Examiners notice these errors immediately.
- Using passive voice when active voice is more natural: 'It is thought by me that...' should always be 'I think that...' or 'It is widely thought that...'
- Omitting the auxiliary verb: 'The report published last year' is a reduced relative clause, not a passive sentence — if you mean the passive, write 'The report was published last year.'
- Stacking passives in one sentence: 'It has been suggested that this should be considered to be addressed' is grammatically possible but practically unreadable.
- Using passive voice in Task 1 bar charts and line graphs where trends need a clear agent: 'Sales increased sharply' is stronger than 'A sharp increase was recorded in sales' in most trend-description contexts.
Tip
When you finish writing your Task 2 essay, scan it specifically for passive constructions. If you have zero, add one modal passive recommendation in your final body paragraph — for example, 'stricter penalties must be imposed on corporations that violate environmental standards.' If you have more than five passives, check each one: could an active construction carry the same meaning more cleanly?
Passive Voice in IELTS Speaking
Passive voice is rarer in natural spoken English, which means using it occasionally in IELTS Speaking Part 3 — where you discuss abstract topics — signals genuine grammatical range. Phrases like 'a great deal of pressure is placed on young people to succeed academically' or 'these decisions are often influenced by economic factors' sound fluent and sophisticated without appearing rehearsed. In Parts 1 and 2, where you describe personal experiences, active voice is almost always more natural and appropriate. Forcing passive constructions into personal narratives — 'the holiday was enjoyed by my family and me' — sounds unnatural and will not impress an examiner.
The underlying principle across both Writing and Speaking is the same: passive voice is a tool, not a status symbol. Use it where it serves the meaning, the register, or the variety of your writing. Use active voice everywhere else. Candidates who internalise this principle — rather than applying passive voice randomly in the hope of appearing academic — are the ones who consistently reach Band 7 and above for grammatical range.
