Passive voice is a grammatical structure used to focus on the person, thing, or result affected by an action rather than the person performing it. It is especially common in formal, academic, scientific, and professional English.
Compare these two sentences:
Active voice: Researchers conducted the experiment in 2025.
Passive voice: The experiment was conducted in 2025.
The active sentence focuses on the researchers, while the passive sentence focuses on the experiment. Both sentences are grammatically correct, but the passive structure is more appropriate when the action or result is more important than the person responsible for it.
For IELTS candidates, understanding passive voice can be particularly useful in formal writing, process descriptions, and discussions of general facts. However, passive voice is only one grammatical structure. Using it does not automatically result in a higher IELTS band score.
Passive Voice Formula
The basic passive voice formula is:
Subject + form of be + past participle + optional by + agent
For example:
Active: The company produces electric cars.
Passive: Electric cars are produced by the company.
The most important feature of the passive voice structure is the use of a suitable form of be followed by the past participle of the main verb.
The form of be changes according to the tense, while the main verb remains in its past participle form.
Passive Voice in Common Tenses
In the present simple, use:
am/is/are + past participle
Example: The products are manufactured in Germany.
In the past simple, use:
was/were + past participle
Example: The building was completed in 2010.
In the present perfect, use:
has/have been + past participle
Example: The report has been completed.
In the past perfect, use:
had been + past participle
Example: The project had been approved before construction began.
In the future simple, use:
will be + past participle
Example: The results will be announced next week.
For continuous passive structures, use being:
am/is/are being + past participle
Example: The road is being repaired.
Learning these patterns is an important foundation for mastering passive voice and using it accurately in academic English.
Passive Voice With Modal Verbs
Passive voice with modal verbs follows a straightforward pattern:
Modal verb + be + past participle
Common modal verbs include can, could, should, must, may, might, and will.
Examples include:
The application must be submitted before Friday.
The problem can be solved with a different approach.
More research should be conducted before a final decision is made.
This structure is useful when expressing ability, possibility, advice, necessity, or obligation. It can also help IELTS candidates vary their sentence structures when discussing academic or social topics.
When Should You Use Passive Voice?
Passive voice should be used when the receiver of an action is more important than the person performing it, or when the performer is unknown, obvious, or irrelevant.
For example:
The stolen car was found yesterday.
In this sentence, the identity of the person who found the car is not important.
Passive voice is also common in formal descriptions:
The samples were collected and analyzed in a laboratory.
However, passive voice should not be used simply because a sentence sounds more academic. Active voice is often clearer and more direct when the person performing the action is important.
For example:
Researchers analyzed the data.
This is often more direct than:
The data was analyzed by researchers.
Good English requires choosing between active and passive voice according to meaning and context.
Passive Voice and IELTS Performance
Understanding passive voice can support IELTS preparation, especially for Writing and, to a lesser extent, Speaking. However, IELTS does not require candidates to use a specific number of passive sentences to achieve a particular band score.
In IELTS Writing, grammatical performance is evaluated as part of Grammatical Range and Accuracy. Candidates are expected to use a range of grammatical structures appropriately and accurately.
Therefore, a sentence such as:
The process is completed in three stages.
can be useful when appropriate, but using an incorrect passive structure may create a grammatical error.
The goal should not be to use passive voice as frequently as possible. Instead, candidates should demonstrate that they can select appropriate grammatical structures and control them accurately.
IELTS Overall Band Score Explained
IELTS provides individual band scores for Listening, Reading, Writing, and Speaking. The overall band score is calculated by averaging these four scores and then rounding the result according to IELTS scoring rules.
For example, suppose a candidate receives:
Listening: 6.5
Reading: 6.5
Writing: 5.0
Speaking: 7.0
The average is 6.25, which is reported as an overall 6.5.
This example shows why improving one skill can influence the overall result. However, there is no guarantee that improving passive voice alone will increase the overall band score.
How Passive Voice Relates to Each IELTS Skill
Listening
Listening does not have a separate grammar score. Performance is primarily based on how accurately candidates understand the recording and answer the questions.
Nevertheless, recognizing passive structures can make spoken English easier to understand. Learners who are familiar with different sentence patterns may process information more efficiently.
Reading
Reading also does not have a separate passive voice score. Candidates answer questions based on information and meaning in the texts.
Passive constructions are common in academic texts, research articles, reports, and formal explanations. Understanding them can therefore help learners identify relationships between actions, subjects, and results.
Writing
Writing is the IELTS skill in which passive voice can be particularly useful.
In Academic Writing Task 1, passive constructions are often appropriate when describing a man-made process where the stages and actions are more important than the people performing them.
For example:
The raw materials are transported to the factory.
The mixture is then heated to a high temperature.
The final product is packaged and delivered to retailers.
However, not every process requires passive voice. Natural processes may be described using either active or passive structures depending on the meaning and sentence construction.
In Writing Task 2, passive voice can also be useful in formal arguments:
It is often argued that technology has transformed modern education.
The key is to use passive structures naturally rather than inserting them into every paragraph.
Speaking
Passive voice is less common in everyday conversation than active voice, but it is still useful when discussing events, processes, rules, or general situations.
For example:
The new policy was introduced last year.
My hometown is surrounded by mountains.
IELTS Speaking rewards effective communication, so clarity and natural language should remain more important than deliberately using complicated grammar.
Is Passive Voice Difficult to Learn?
The basic concept of passive voice is not particularly difficult. The main challenge is using it correctly across different tenses and contexts.
Learners commonly have difficulty choosing the correct form of be, remembering irregular past participles, and deciding whether passive or active voice is more appropriate.
For example:
Incorrect: The report was write yesterday.
Correct: The report was written yesterday.
Another common error is forgetting the auxiliary verb:
Incorrect: The products manufactured in this factory.
Correct: The products are manufactured in this factory.
Regular practice is essential because understanding the formula does not automatically lead to accurate usage.
Exercises for Effective Practice
Effective exercises should involve more than simply memorizing formulas.
Start with sentence transformation exercises. Change active sentences into passive sentences and identify the tense before making the transformation.
For example:
Active: The company launched the product in 2024.
Passive: The product was launched in 2024.
Next, practice completing sentences with the correct form of be and the appropriate past participle. After that, work on modal passive structures and passive sentences in different tenses.
Finally, apply passive voice to IELTS-style writing tasks. This helps you understand when the structure is genuinely useful rather than simply practicing grammar in isolation.
Common Passive Voice Mistakes
One common mistake is using the wrong past participle:
Incorrect: The letter was send yesterday.
Correct: The letter was sent yesterday.
Another mistake is using the wrong form of be:
Incorrect: The documents is checked every morning.
Correct: The documents are checked every morning.
Learners also frequently add by when it is unnecessary. If the person performing the action is unknown, obvious, or unimportant, the agent can normally be omitted.
For example:
The road was repaired last month.
There is no need to add a by phrase unless the person or organization responsible is relevant.
Finally, avoid overusing passive voice. Strong English writing normally combines active and passive structures according to purpose.
