Active vs. Passive Voice on the SAT
Turn Grammar into Easy Points
Master sentence structure, punctuation, and clarity with repeatable rules.
Guard the Sentence Core
Identify the subject and verb, then make sure punctuation does not split them or add extra ideas.
- Find the subject + verb first. That is the sentence core.
- Only add commas around extra information, never inside the core.
- Re-read the sentence without the modifier to test clarity.
Why Active vs. Passive Voice Matters on the SAT
Questions about active vs. passive voice on the SAT Reading and Writing section may look like style judgment calls, but they actually test a single, learnable pattern. The test regularly asks you to choose between two versions of a sentence, and one is almost always more direct, more concise, and just cleaner than the other. Once you know what to look for, these become some of the fastest points on the entire exam.
This post will teach you exactly what active and passive voice are, how to spot passive constructions in seconds, and, critically, when the SAT actually wants you to keep the passive version. By the end, you'll have a reliable strategy and enough practice to feel confident every time voice shows up on test day.
What Are Active and Passive Voice?
Every sentence with an action verb has a voice, it's either active or passive. The difference comes down to one question: Is the subject doing the action, or receiving it?
- Active voice: The subject performs the action.
"The researcher conducted the experiment."
The researcher (subject) is doing the conducting. - Passive voice: The subject receives the action.
"The experiment was conducted by the researcher."
The experiment (subject) isn't doing anything, it's being acted upon.
Notice the pattern in the passive version: a form of "to be" (was) plus a past participle (conducted), often followed by a "by" phrase that names the real doer. That structure, "to be" + past participle + "by", is your signal.
Here's a quick trick: if you can add "by zombies" after the verb and the sentence still makes grammatical sense, it's passive. "The experiment was conducted by zombies", yep, that's passive. "The researcher conducted by zombies", that doesn't work, so it's active.
Common Misconceptions About Active vs. Passive Voice
Before we go further, let's clear up three things students get wrong constantly:
- Passive voice is NOT always wrong. The SAT does not automatically penalize it. It penalizes passive voice when an active alternative is clearer, more concise, or more direct. Sometimes passive is the right call.
- Past tense is NOT the same as passive voice. "She walked" is active and past tense. "She was praised" is passive and past tense. Tense tells you when; voice tells you who's doing what.
- Long sentences aren't necessarily passive. A sentence can be active and lengthy, or passive and short. Length and voice are independent.
How This Appears on the SAT
On the SAT Reading and Writing section, active-vs-passive questions typically show up as sentence revision or rhetorical synthesis items. You'll see a sentence (sometimes underlined) and four choices that rephrase it. Here's what to watch for:
The Quick Voice Check
- Wordiness signal. If one answer choice is noticeably shorter and follows a clean subject → verb → object pattern, it's likely the correct active-voice option.
- "By" phrase at the end. A trailing "by [someone]" is a dead giveaway of passive construction. Ask yourself: could that someone just be the subject instead?
- Missing agent. Sometimes passive voice hides who did something. If the passage context makes the agent important, the active revision is almost always preferred.
- The exception. If the passage deliberately emphasizes the receiver of the action (e.g., "The vaccine was approved by the FDA" in a passage about the vaccine, not the FDA), passive may be the right call.
Time-saving tip: Read the shortest answer choice first. On conciseness questions, the SAT overwhelmingly rewards brevity and directness, both hallmarks of active voice.
Practice: Spot the Stronger Construction
Let's put this into practice with SAT-style questions. These move from straightforward to slightly tricky, just like the real test. Take your time and read each explanation carefully.
Which revision most effectively combines clarity and conciseness?
Which revision improves the clarity of the underlined portion?
Which revision makes the sentence more direct without losing important information?
Should the writer revise "the novel was largely overlooked by the reading public" to active voice?
Key Takeaways for Active vs. Passive Voice
- Active voice puts the doer in the subject position and is usually more concise and direct. The SAT rewards this in most situations.
- Passive voice is not automatically wrong. When the receiver of the action is the main topic of the passage, passive can be the better choice, and the SAT tests whether you know that.
- Spot passive voice quickly: look for a "to be" verb + past participle, often followed by a "by" phrase. If you can add "by zombies" and it works grammatically, it's passive.
- On the SAT, the most concise answer that preserves meaning is almost always correct, and that answer is usually in active voice.
Conclusion: The Core Rule for Active vs. Passive Voice
Active vs. passive voice questions are among the most predictable on the SAT Reading and Writing section. Once you train your eye to spot the "was [verb]-ed by" pattern and ask yourself whether the agent should just be the subject, these questions become quick, confident wins. Keep practicing with real SAT-style questions, and you'll start seeing passive constructions jump off the page, on the test and in your own writing.
Remember: Find the real doer, check if they should be the subject, and choose the most direct option. That one habit can turn voice questions into some of the easiest points on test day.
