Are there times when passive voice is required in formal writing?

From NCERT Asked by Anonymous from Dallas, United States 23 Oct 2026, 9:31 PM IST Updated

In one line

Sometimes, passive voice is the best or required choice in formal writing, especially when the doer is unknown or not important.

The rule

In passive voice, the subject receives the action, often focusing on the action or the result, not the doer.

Formula: Subject + form of 'to be' + Past Participle + (by + Agent)

Let's understand it simply

Imagine you are writing a report about a cricket match. You want to say, “The ball was hit for a six.” Here, who hit the ball is not important — the action (hitting a six) matters more. This is where passive voice helps. It lets you talk about what happened, not always who did it.

How it works

  1. Decide what you want to focus on: the action or the doer.
  2. If the action/result is more important, use passive voice.
  3. Change the object of the active sentence into the subject of the passive sentence.
  4. Add the correct form of 'to be' (is, was, are, etc.) and the past participle (V3) of the verb.
  5. Add 'by + agent' only if you need to mention who did the action.
How to change active to passive voice
  1. Find the object in the active sentence.
  2. Make it the subject of the passive sentence.
  3. Add the correct form of 'to be'.
  4. Use the past participle (V3) of the verb.
  5. Add 'by + agent' if needed.

The story behind it

Passive voice has been used in English for hundreds of years. It became popular in formal writing, like reports and scientific papers, because it helps focus on facts and results, not on people. For example, in science, the result is more important than the scientist.

Where you see it in real life

  • Scientific reports: “The experiment was conducted at 10 AM.” (Who did it is not important.)
  • Official notices: “The school will be closed tomorrow.” (Focus is on the closure, not who decided.)
  • News headlines: “A new bridge was built over the river.” (The action matters more than the builders.)
  • Instructions: “The form must be filled in blue ink.” (Anyone can fill it; focus is on the action.)
  • Results: “The match was won by India.” (Focus on the win, not only the players.)

Why it matters

  • Used in formal letters, reports, and scientific writing.
  • Makes writing more objective and less personal.
  • Helps when the doer is unknown, unimportant, or obvious.
  • Needed for certain exam questions and official documents.

Common mistakes

  • Using passive voice everywhere makes writing dull. Use it only when needed.
  • Forgetting to change the verb to the past participle (V3) form.
  • Missing the correct form of 'to be' (is, was, were, etc.).
  • Adding 'by' when it is not needed (if the doer is not important, leave it out).

Remember it

Use passive voice in formal writing when the action or result is more important than who did it.

Check yourself

Why is passive voice used in scientific reports?

Because the result is more important than who did the experiment.

Change this to passive: 'The teacher gave the homework.'

The homework was given by the teacher.

Should you always mention the doer in passive voice? Why or why not?

No, only if it is important; often the doer is unknown or not needed.

Quick recap

  • Passive voice is common in formal writing when the doer is unknown or unimportant.
  • It focuses on the action or result, not the person who did it.
  • Use passive voice in reports, instructions, and official notices.
  • Do not overuse passive voice; use it only when needed.
