Using Active and Passive Voice

Every sentence places one idea in its most prominent position, the subject slot at the beginning. In active voice, "The committee rejected the proposal," the committee occupies that position. In passive voice, "The proposal was rejected by the committee," the proposal does, and the sentence could even drop the agent entirely: "The proposal was rejected." When you revise, ask a simple question of every sentence: which idea deserves that opening position right now?

Watch which noun phrases repeat across a paragraph. If "the proposal" has been the subject of several sentences in a row, keeping it as the grammatical subject through passive voice, rather than switching to "the committee" through active voice, keeps the paragraph's focus steady and easier for a reader to track.

Passive voice lets a writer omit the agent altogether, which is useful when the actor is unknown, irrelevant, or intentionally left unnamed, as in "Mistakes were made." A careful reader notices when that omission is a reasonable stylistic choice and when it is being used to avoid stating who is accountable. Revising a sentence from passive to active, turning "Mistakes were made" into "We made mistakes," restores the missing agent and usually makes the statement stronger and more direct. Part of using voice well is recognizing this effect in texts you read and controlling it on purpose in texts you write.

Original draft: "A researcher at the lab discovered the error. The lab director then corrected the error. The university cut funding for the project shortly afterward."

Revised to keep a single focus running through the paragraph: "An error was discovered by a researcher at the lab. It was corrected by the lab director. Shortly afterward, the university cut funding for the project."

Neither version is simply "more correct." The original keeps people as agents throughout and suits a narrative about who did what. The revision keeps "the error" as the throughline for its first two sentences, which suits a report focused on the problem's progress, then switches back to active voice in the final sentence, "the university cut funding," so the consequence lands with more force. That final switch is itself a deliberate rhetorical choice: an active, agent-named sentence carries more weight than a passive one would in that position.

Lab reports and technical writing often favor passive voice so that the procedure, not the person performing it, stays the subject: "The solution was heated to 80 degrees Celsius." Journalism and narrative writing tend to favor active voice because it names actors and keeps events moving efficiently. Persuasive and analytical essays typically mix both: active voice drives the argument forward, while passive voice is used selectively to foreground the evidence or outcome the writer wants the reader to weigh most heavily.

When you revise your own essays, check whether each passive sentence is doing real work, controlling emphasis, varying sentence rhythm, or appropriately leaving out an agent, or whether it is simply a default choice that weakens the sentence. Overusing passive voice in writing that should feel direct and argumentative can make even accurate claims sound vague or evasive.

Before finishing a draft, read each sentence and ask three questions: What idea sits in the subject position, and is that the idea I want emphasized? Is the agent named, and should it be? Does this sentence's voice match the voice of the sentences around it, or does a deliberate shift here serve a purpose? Answering these questions turns active and passive voice from a grammar rule you follow into a stylistic tool you control.
