Active Versus Passive: When and Why to Choose

What this session covers

The most common mistake in teaching the passive is presenting it as a neutral grammatical option — as if active and passive sentences are simply two ways of saying the same thing. They are not. Every choice between active and passive changes what is foregrounded, what is omitted, and what register the text projects. This lesson focuses entirely on the decision — when to choose passive, when active is better, and how to recognise when the passive is being over-used or misused. Teachers who understand this can give learners genuinely useful guidance on writing quality, not just grammatical correctness.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
Think about the last piece of formal writing you read — a school report, a letter, an announcement. How many passive sentences were there? Did they all feel appropriate, or did any feel evasive or unnecessarily impersonal?
Q2
Which of these tendencies have you noticed in your learners writing: avoiding the passive entirely, using the passive for every sentence, or using the passive to avoid naming someone when clarity would be better?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
Read these two versions of the same school notice:
Version A: I will announce the exam results at the assembly on Friday. All students must attend.
Version B: The exam results will be announced at the assembly on Friday. All students must attend.

Both versions contain the same facts. But only one sounds like a typical school notice. Which one? What is different about the effect of each version?

Version B (passive) sounds like a typical school notice. Version A (active) sounds more like a personal message. The passive in Version B creates institutional authority and impersonality — it is not about the teacher announcing results, it is about the results being announced, which is a fact of school life. This impersonality is appropriate and expected in notices, policies, and official documents. Choosing passive or active is partly a register decision: what kind of communication is this?

2
Read these two sentences from an investigation report:
A: The head teacher failed to report the incident.
B: The incident was not reported.

Both describe the same failure. But they have very different effects. What is different about the responsibility each sentence implies? When might a writer choose each one?

Sentence A (active) names the agent clearly — the head teacher failed. Sentence B (passive) omits the agent. The responsibility is obscured. In an accountability report where the agent is known, the passive may be deliberately evasive. In an early investigation where facts are not confirmed, omitting the agent may be appropriately cautious. The passive is not always neutral — sometimes the active is more honest. Teachers should teach learners to ask: who benefits from the agent being omitted?

Read this paragraph and decide which passives feel appropriate and which feel unnecessary:
The Industrial Revolution was started in Britain. Many factories were built. Workers were employed. Long hours were worked by them. Poor conditions were experienced by many people.

All five sentences are passive. Does every passive feel natural here?

The first three passives are relatively natural. But Long hours were worked by them and Poor conditions were experienced by many people are awkward — they use the passive unnecessarily and produce unnatural sentences. They worked long hours and Many people experienced poor conditions are both more natural. The problem with over-using the passive is that it becomes monotonous and creates awkward by-phrases. Good writing mixes active and passive purposefully — the passive is chosen when it serves a communicative purpose; the active when the agent matters or when the sentence sounds more natural that way.

The Pattern — What You Just Discovered

Active and passive voice are not interchangeable — each makes a different communicative choice. The passive foregrounds the thing affected and backgrounds or omits the agent. It is appropriate when the agent is unknown, unimportant, or deliberately omitted for formality or diplomacy. The active is better when the agent is the communicative focus, when clarity about responsibility is important, or when the passive sounds unnatural.
Tense / FormUse / MeaningExampleKey time words
Choose passive when Example Reason
Agent is unknown The window was broken. We do not know who broke it.
Agent is obvious or unimportant The register is checked daily. Everyone knows teachers check it.
The thing affected is the focus The results will be announced on Friday. The results matter; who announces them does not.
Formal or institutional register All applications must be submitted by Monday. Impersonal authority — appropriate for notices and policies.
Diplomatic — avoid naming someone An error was made in the earlier communication. Acknowledges the problem without assigning blame.
Choose active when Example Reason
The agent is the communicative focus Dr Kimani founded this school in 1952. Who founded it is historically significant.
Clarity about responsibility matters The head teacher failed to inform parents. The active names who was responsible.
The passive would sound unnatural She worked hard. Some concepts are simply more natural in active.
Special Rule / Notes

THE PASSIVE AND ACCOUNTABILITY
One of the most important things teachers can do is help learners understand that the passive can be used to evade responsibility. In political language, corporate communications, and management reports, the passive is sometimes used deliberately: Mistakes were made. Redundancies will be implemented. Procedures were not followed. These passive sentences remove accountability. Learners who understand this can read public communications more critically and can make more honest choices in their own writing — using the active when clarity and accountability are what the situation calls for.

READABILITY AND PASSIVE OVERUSE
Long stretches of passive voice make text harder to read. Research on readability consistently shows that active constructions are processed more quickly and remembered more easily. This does not mean the passive is bad — it means the passive should be used purposefully, not as a default. Professional writing guidance advises: use the active as your default, and switch to passive only when it serves a specific communicative purpose. Teaching learners this principle — active as default, passive by choice — produces more readable, more purposeful writing.

ACTIVE OR PASSIVE — HOW TO DECIDE - Is the agent the key piece of information? Active. - Is the agent unknown, obvious, or unimportant? Passive (omit by). - Is the agent known and relevant? Passive with by-phrase. - Does the passive create appropriate formality and impersonality? Passive. - Is the passive obscuring important accountability? Active may be more honest. - Does the passive sentence sound awkward? Consider whether active is more natural. - Is every sentence in the text passive? Mix in some active sentences for readability.

Common Student Errors

WhyThis passive is awkward — the by-phrase is clumsy and the active is far more natural. Not every action needs to be expressed in the passive.
WhyIn a formal notice, the passive is more appropriate — the results are the institutional focus, not who is giving them.
WhyIf the agent is known and accountability matters, the active is more honest.
WhyThe by-phrase adds nothing — everyone knows teachers mark books. Omitting it makes the sentence cleaner.
The students were taught the new rules. OR: The students learned the new rules.
WhyWere learn is not a passive. Passive needs be + past participle (were taught).

Check Your Understanding — Part 1

For each situation, decide whether active or passive is more appropriate and explain your choice.

A school notice announcing that term begins on 8th January: The new term ______ on 8th January.___________
A report sentence about a missing policy document: The policy document ______ (not / file) correctly before the inspection.___________
An essay about school history: ______ the school in 1943 by missionaries who wanted to expand education.___________
A direct email from a teacher to a parent: I ______ (send) your child results to you by the end of the week.___________
A notice about a school rule: Mobile phones ______ (not / permit) on school premises during the school day.___________

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence uses active or passive inappropriately for the context described. Rewrite it more appropriately and explain why.

Context: a formal school report. Sentence: I assessed the students using a mix of oral and written tasks.
Write the correct sentence:
Explain why it is wrong:
Students were assessed using a mix of oral and written tasks.
In a formal report, the passive is more appropriate — the assessment is the focus, not the teacher's personal role. The passive also creates the impersonal formal register expected in school reports.
Context: an investigation report where the head teacher is known to have ignored a complaint. Sentence: The complaint was not addressed promptly.
Write the correct sentence:
Explain why it is wrong:
The head teacher did not address the complaint promptly.
When the agent is known and accountability matters, the active is more honest. The passive here obscures responsibility. Active naming is more appropriate in an accountability document.
Context: a history essay about the school founder. Sentence: The school was established in 1902, and education was provided to hundreds of children by him over the following decades.
Write the correct sentence:
Explain why it is wrong:
The school was established in 1902, and over the following decades he provided education to hundreds of children.
Once the founder is established as the subject of the essay, switching to the active (he provided) reads more naturally than a clumsy by-phrase passive.
Context: a general school notice. Sentence: I am going to announce the prize-giving ceremony details next week.
Write the correct sentence:
Explain why it is wrong:
Details of the prize-giving ceremony will be announced next week.
In a school notice, the passive is more appropriate — it creates institutional impersonality. The notice is institutional information, not a personal message.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — SAME INFORMATION, DIFFERENT EFFECT (7 minutes): Write the same piece of information in active and passive on the board — for example, an announcement and a personal message. Ask learners: which sounds like a school notice? Which sounds like a text message? Establish that active and passive create different registers and effects.

2

STEP 2 — WHEN IS PASSIVE APPROPRIATE? (8 minutes): Present five scenarios: (1) a window is broken — no one knows who; (2) a policy everyone must follow; (3) a school founder; (4) a mistake in a report — the author is known; (5) an annual exam schedule. For each scenario, ask: should the key sentence be active or passive? Why?

3

STEP 3 — THE ACCOUNTABILITY QUESTION (7 minutes): Present two passive sentences that obscure responsibility. Ask learners: who made the mistakes? Does omitting the agent serve the reader or protect the writer? Discuss when omitting an agent is appropriate and when it is evasive.

4

STEP 4 — OVER-USE EDITING (8 minutes): Give learners a short paragraph where every sentence is passive — including several that would be more natural in the active. Ask them to identify which passives are appropriate and which should be converted to active.

5

STEP 5 — WRITE WITH PURPOSE (5 minutes): Ask learners to write three sentences about a real situation at their school — one where the passive is clearly the better choice, one where the active is clearly better, and one where either could work. Share and discuss.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 Active or Passive? Decision Cards
Read ten sentences — each in a specific context. Learners decide: active or passive for this context, and why. Focus the discussion on the reasoning, not just the answer.
Example sentences
Context: formal report. Sentence about assessment → passive
Context: personal email to parent. Sentence about sending results → active
Context: school notice. Rule about phones → passive
Context: investigation. Named person failed to act → active (accountability)
2 Evasive or Appropriate? Passive Analysis
Write five passive sentences — some where omitting the agent is appropriate, some where it is evasive. Ask learners to decide which are acceptable and which should be rewritten with the active to restore accountability.
Example sentences
Acceptable: The exam papers were lost in transit. (genuinely unknown agent)
Acceptable: Results will be published in July. (institutional announcement)
Evasive: The safeguarding issue was not reported for three weeks. (if responsible person is known)
Evasive: The parent's complaint was overlooked. (if someone specific overlooked it)
3 Mixed Paragraph Editing
Give learners a paragraph that is either all passive or all active. Ask them to identify which sentences would benefit from switching voice and rewrite with an appropriate mix. Annotate each sentence with the reason for the choice.
Example sentences
Over-passive paragraph: The new curriculum was introduced last year. Teachers were trained during the holidays. New materials were provided by the ministry. Lessons were planned carefully. Good results were achieved by students this term.
Suggested: Keep passives where appropriate (curriculum introduced, materials provided); switch where active is more natural (Teachers trained carefully / Students achieved good results this term).

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Teach learners the decision question first: why am I using passive here? If you cannot answer, default to active.
Help learners identify the passive in texts they read and discuss whether each serves a clear communicative purpose.
Discuss the accountability dimension with advanced learners — understanding that the passive can obscure responsibility helps them read public communications more critically.
Avoid over-drilling passive formation without discussing when to use it — learners who can form it but not explain why will use it randomly.
Teach active as the default: start from active, choose passive when it serves a specific purpose.
What is the one change you will make next time you teach this grammar point?

Key Takeaways

1 Active and passive are not interchangeable — each makes a different communicative choice about what is foregrounded and what is omitted.
2 Choose the passive when the agent is unknown, obvious, or unimportant; when formal or institutional register is needed; or when diplomatic omission is appropriate.
3 Choose the active when the agent is the key information, when clarity about responsibility matters, or when the passive sounds unnatural.
4 The passive can be used to avoid accountability — sometimes appropriate (genuinely unknown agent), sometimes evasive (known agent deliberately hidden).
5 Good writing mixes active and passive purposefully. Active should be the default; passive a deliberate choice.
