Let’s be honest: grammar can be dry. But if you’re aiming for a Band 7 or higher in IELTS Academic Writing, mastering the **passive voice** isn’t just a “nice to have”—it’s essential.

I’ve seen so many students struggle with this. They write entire essays in the active voice, which is great for a personal blog or a chat with friends, but in an academic context? It can sound a bit too informal or subjective.

In this guide, I’m going to show you exactly how and when to use the passive voice to boost your Grammatical Range and Accuracy score. Don’t worry, we’ll keep it simple and practical.

What is the Passive Voice?

In English, sentences are usually **active**. The subject does the action.

* **Active:** *The government (subject) built (verb) a new bridge (object).*

In the **passive** voice, we flip this around. The object becomes the focus.

* **Passive:** *A new bridge (subject) was built (verb) by the government (agent).*

Notice how the focus shifts from *who* did it (the government) to *what* happened (the bridge was built). In academic writing, the action or the result is often more important than the person doing it.

When to Use Passive Voice in IELTS

You shouldn’t use the passive voice all the time—that would make your writing heavy and hard to read. However, there are two specific places in the IELTS test where it is absolutely crucial.

1. Writing Task 1: Process Diagrams

If you get a process diagram in Task 1, you *must* use the passive voice. Why? Because we don’t know (and don’t care) who is doing the action.

Imagine a diagram showing how chocolate is made. You wouldn’t say:
* *”Workers pick the cocoa beans.”*

Instead, you would say:
* *”The cocoa beans **are picked**.”*

See the difference? It sounds much more objective and professional.

2. Writing Task 2: Academic Essays

In Task 2 essays, you want to sound objective. Using “I” or “we” too much can make your argument sound like just a personal opinion rather than a reasoned fact.

* **Too Personal:** *I think people should recycle more.*
* **Academic:** *It **is argued** that recycling should be encouraged.*

Using phrases like *”It is believed that…”* or *”It can be seen that…”* helps you distance yourself from the argument, making it sound more authoritative.

How to Form the Passive Voice

The formula is simple:

> **Subject + Form of “To Be” + Past Participle (V3)**

Here is how it looks in different tenses:

| Tense | Active | Passive |
| :— | :— | :— |
| **Present Simple** | People speak English here. | English **is spoken** here. |
| **Past Simple** | They built the house in 1990. | The house **was built** in 1990. |
| **Present Perfect** | Someone has cleaned the room. | The room **has been cleaned**. |
| **Future Simple** | They will finish the project. | The project **will be finished**. |

Common Mistakes to Avoid

I often see students making these mistakes. Watch out for them!

1. Using the Wrong Tense

Make sure the “to be” verb matches the tense of the sentence. If you are describing a process that happens regularly (like making chocolate), use the **Present Simple Passive** (*is made*, *are picked*). If you are describing a map from the past, use the **Past Simple Passive** (*was constructed*, *were removed*).

2. Overusing It

Don’t write your entire essay in the passive voice. It can become boring and hard to follow. Use it strategically to vary your sentence structures. A good mix of active and passive sentences shows the examiner you have flexible grammar skills.

3. Forgetting the Agent (When It Matters)

Usually, we drop the “by…” part. *”The bridge was built”* is fine; we don’t need to say *”by construction workers”*—it’s obvious. But if the agent is important, keep it.
* *”The theory was proposed **by Einstein**.”*

Practice Makes Perfect

Let’s try a quick exercise. Convert these active sentences into the passive voice:

1. The university accepts applications online.
2. They are renovating the library.
3. Pollution affects the environment.

*(Answers: 1. Applications are accepted online. 2. The library is being renovated. 3. The environment is affected by pollution.)*

Sound familiar? These are exactly the kinds of sentence structures you’ll need for a high score.

Final Thoughts

Using the passive voice correctly is a hallmark of academic writing. It allows you to shift the focus to what matters—the action, the process, or the argument—rather than the person.

Next time you practice a Writing Task 1 process or a Task 2 essay, challenge yourself to include at least 3-4 passive sentences. You’ll be surprised at how much more “academic” your writing sounds!

You’ve got this. Good luck with your preparation!
