6. When Not to Use Passive Voice

Voice conversion tests mechanical accuracy, but a smaller, subtler slice of exam questions — usually phrased as "improve the sentence" or "choose the sentence with the better usage" — test judgment: knowing when passive voice, though grammatically correct, is the worse choice.

When active voice is clearly preferable

1. When the doer matters and clarity/directness is the goal. Active voice names who is responsible in the most natural, front-loaded way. Administrative and everyday communication defaults to active for this reason.

Weak (passive, agent buried or dropped): A decision has been taken to shut down the unit. Better (active, responsibility clear): The board has decided to shut down the unit.

2. When the sentence would otherwise become needlessly long or vague. Passive constructions often require extra words (auxiliary + participle + "by") for the same information active voice delivers more economically.

Weak: The children were made to feel welcome by the new teacher. Better: The new teacher made the children feel welcome.

3. In instructions, narratives, and most everyday storytelling. Passive voice slows down and de-personalises action — fine for a lab report, wrong for a story or a set of instructions where the reader needs to follow who does what, when.

Weak (passive, in a set of instructions): The switch should be pressed, and the machine should then be allowed to warm up. Better (active): Press the switch, and let the machine warm up.

4. When "get"-passives or vague passives would sound too casual for the register. As noted in Section 4.6, "get" passives are informal by nature and should be avoided in formal writing, reports, and most exam "correct usage" answers, even though they are perfectly natural in speech.

5. When overusing passive voice buries too many agents across a paragraph, making it read like a diffusion-of-responsibility document. A single passive sentence is a stylistic choice; a whole paragraph of them, each omitting its agent, reads as evasive — a pattern exam "improve the passage" questions specifically flag.

Weak (a chain of agentless passives): Mistakes were made. The budget was overspent. Deadlines were missed. Corrective action will be taken. Better (agency restored where it matters): The finance team overspent the budget and missed two deadlines; the department head has now ordered corrective action.

When passive voice is genuinely the better choice

Passive voice is not a "worse" construction in general — it is the correct tool in several specific, well-defined situations, and exams equally test recognition of these.

1. When the agent is unknown, irrelevant, or intentionally vague.

The ancient manuscript was discovered in a sealed clay jar. (nobody knows, or it doesn't matter, who first found it)

2. In scientific, technical, and administrative writing, where the process matters more than the performer. Scientific method emphasises the procedure and result as replicable, impersonal facts, not the personality of the researcher performing them.

The solution was heated to 80°C and then filtered through fine muslin cloth. All applications must be submitted along with two self-attested photocopies.

3. When the receiver of the action is simply more important to the discussion than the doer.

The Constitution of India was adopted on 26 November 1949. (the document and the date matter far more here than naming every individual assembly member)

4. To maintain an impersonal, formal, or diplomatic tone — especially useful for softening criticism or avoiding blame.

Blunt/active: You made several errors in this invoice. Softer/passive: Several errors were noticed in this invoice.

5. When the previous sentence's topic should remain the subject for smooth flow (cohesion across sentences).

The bridge was inaugurated last week. It had been under construction for nearly four years and was finally opened to public traffic on Monday. Keeping "the bridge" as the subject across both sentences (via passive in the first) creates smoother, more readable prose than abruptly switching to naming the construction company.

6. In headlines, notices, and captions, where brevity and impersonality both favour dropping the agent.

Two held for ticket black-marketing near the stadium. (headline style — the agent, presumably the police, is understood and need not be spelled out)

The exam takeaway: neither voice is inherently "correct" English — the test is whether you can identify, in context, which voice serves the sentence's actual communicative purpose. When a question asks you to "improve" or "choose the better version" of a sentence rather than simply "convert" it, check first whether the agent is important (favour active) or irrelevant/impersonal/procedural (favour passive), rather than mechanically applying a formula.
