I was sitting in my small home office last Tuesday, staring at a stack of IELTS essays, when I heard a particularly dissonant note from my choir rehearsal recording. It reminded me of the way students approach grammar: they try so hard to be “correct” that they end up sounding utterly robotic. Most textbooks will give you a dry, endless list of formulas for how to use the passive voice, treating it like some complex mathematical equation you need to solve. But after nineteen years of marking exams, I can tell you that the problem isn’t that you don’t know the formula; it’s that you’re using it to hide. You’re using it to pad your word count or to sound “academic,” when in reality, you’re just making your writing heavy and unreadable.
I’m not here to give you another lecture on auxiliary verbs and past participles. Instead, I am going to show you how to stop making the specific, repetitive errors that tank your marks in the writing section. I will teach you how to use the passive voice with precision and purpose, so it actually serves your argument rather than burying it. We are going to focus on the habits that examiners look for, stripping away the fluff to get you to the marks you actually deserve.

Mastering the Grammatical Structure of Passive Voice
To get this right, you have to stop thinking about the sentence as a single unit and start looking at the relationship between the actors. The grammatical structure of passive voice relies entirely on a simple formula: the verb to be plus the past participle. It sounds straightforward, but in the heat of an exam, students often trip up on the tense. If your sentence is in the past continuous, your passive must reflect that. You cannot simply swap the subject and object and hope for the best; you must ensure the conjugation matches the timeframe of your original thought.
The real trick, however, lies in identifying the subject and object before you even pick up your pen. In an active sentence, the subject performs the action. In a passive construction, that same “doer” becomes secondary, or disappears entirely, while the object moves into the spotlight. I see so many candidates struggle here because they try to force a passive structure where the action is actually being performed by an unclear agent. If you can’t clearly identify who is doing what, you’re going to end up with a sentence that is structurally sound but logically completely broken.
Identifying the Subject and Object to Avoid Errors
Before you even attempt to flip a sentence into the passive, you must master the art of identifying the subject and object. I see this mistake in almost every essay I grade: students try to transform a sentence without actually knowing who is doing the action and who is receiving it. If you can’t clearly distinguish between the “doer” and the “receiver,” your transformation will fall apart, and you’ll end up with a sentence that is grammatically incoherent.
Think of it as a simple swap. In an active sentence, the subject performs the action. To use the passive voice correctly, that object must step forward to become the new subject. If you rush this step, you’ll likely misplace your auxiliary verbs or mess up your passive voice conjugation rules. I always tell my students: slow down. Take a pen, draw an arrow from the subject to the verb, and another from the verb to the object. If you don’t get the foundation right, all the formal writing style tips in the world won’t save your score from a structural collapse.
Five Ways to Stop the Passive Voice from Tanking Your Score
- Stop overusing it just because it sounds “academic.” I see students trying to sound sophisticated by turning every sentence into a passive construction, but they end up with a bloated, unreadable mess. If the person doing the action is important, just say it. Use the active voice to keep your momentum.
- Watch your verb forms like a hawk. A mistake I’ve seen more than fifty times is the “lazy” passive—forgetting the auxiliary ‘to be’ or using the wrong participle. It’s not just “the letter sent”; it’s “the letter was sent.” If that auxiliary is missing, you aren’t just losing style points; you’re losing fundamental grammar marks.
- Don’t let the “by” phrase become a crutch. If you find yourself adding “by the researcher” or “by the government” to the end of every single sentence, you’re likely using the passive unnecessarily. Only use the “by” phrase if the agent is actually vital information. Otherwise, it’s just extra words that add zero value to your essay.
- Check your tense consistency. One of the quickest ways to confuse an examiner is to shift from an active past tense to a passive present tense mid-paragraph. If your narrative is set in the past, your passive constructions must respect that. “The data was collected” is fine; “The data is collected” in a past-tense report is a red flag.
- Use the passive strategically for emphasis, not by default. The real strength of the passive voice is its ability to shift the focus to the recipient of the action. Use it when the “what” is more important than the “who.” If you use it correctly to highlight a result, you look like a master; if you use it everywhere, you look like you’re struggling with basic sentence structure.
Putting It Into Practice
We have covered a lot of ground today, from the mechanical construction of the verb to the crucial task of identifying your subject and object. Remember, the passive voice isn’t a trap to be feared, but a tool to be used with surgical precision. If you can master the shift from active to passive without losing track of your auxiliary verbs, you are already ahead of most of my students. Don’t let those common errors—the ones I’ve been noting in my ledger for nearly two decades—creep back in. Keep your focus on clarity and purpose; if the agent of the action isn’t important, use the passive, but if you find yourself overusing it to the point of sounding robotic, step back and switch to the active voice.
I know that sitting for these exams can feel like an uphill battle, especially when you feel like you’re constantly fighting against your own ingrained habits. But please, don’t be discouraged by the complexity of the rules. Language is a skill, much like my choral singing; it requires rhythm, discipline, and repetition before it truly feels natural. You aren’t just memorizing formulas; you are training your brain to communicate with sophistication. Stay diligent, keep practicing those structures, and remember that every mistake you correct today is a mark you secure for yourself on exam day. You can do this.
Frequently Asked Questions
When exactly should I switch from the active voice to the passive voice without making my writing sound clunky or unnatural?
Switch to the passive voice when the “doer” is obvious, irrelevant, or—most importantly—when you want to shift the focus onto the result. If you’re writing a report and the action itself is more important than who performed it, use the passive. However, don’t overdo it. If every sentence follows a “Subject + was + verb” pattern, your writing becomes heavy and sluggish. Use it strategically to highlight the recipient of the action, not as a crutch.
Can I use the passive voice in every tense, or are there certain ones that will make my exam essay look amateur?
Technically, you can use the passive in any tense, but just because you can doesn’t mean you should. If you rely on the present perfect passive in every single paragraph, your writing starts to feel heavy and sluggish. It’s a common trap. To keep your essay from looking amateur, use the passive for facts or when the actor is unknown, but stick to the active voice for your main arguments. Variety is what earns the marks.
How do I know if I'm overusing the passive voice and losing the "flow" that examiners are looking for?
Read your work aloud. If you find yourself breathless or tripping over long strings of “was,” “been,” or “by,” you’ve lost the rhythm. Examiners look for a dynamic “flow,” which requires a balance of energy. If every sentence feels like a heavy, static report, you’re hiding behind the grammar. Use the passive for emphasis, but if it’s your default setting, your writing will feel sluggish and, quite frankly, lifeless.
