What you'll learn
Active and passive voice is tested directly in CXC CSEC English Language Paper 1, where candidates are asked to convert between the two, and indirectly in Paper 2, where the choice of voice affects clarity, tone and the expressive quality marks. Voice is not about time, and it is not a matter of right and wrong: both voices are grammatically correct, and the skill being assessed is knowing which one serves your purpose. The active voice puts the doer first and is generally more direct; the passive voice puts the receiver first and is useful when the doer is unknown, unimportant or deliberately concealed. By the end of this guide you should be able to identify voice in any sentence, convert accurately in both directions across all tenses, recognise when the passive is the better choice, avoid the vague and wordy passive that weakens writing, and understand why scientific and official registers rely on it so heavily.
Key terms and definitions
Active voice — a sentence construction in which the subject performs the action of the verb
Passive voice — a sentence construction in which the subject receives the action of the verb
Agent — the person or thing performing the action, introduced by by in a passive sentence
Transitive verb — a verb that takes a direct object and can therefore be made passive
Intransitive verb — a verb that takes no direct object and cannot be made passive
Direct object — the noun receiving the action of the verb in an active sentence
Agentless passive — a passive sentence in which the agent is omitted entirely
Register — the level of formality appropriate to a particular context and audience
Nominalisation — turning a verb into a noun, which often accompanies passive constructions and adds weight
Core concepts
Recognising the two voices
In the active voice, the subject does the action: The council approved the plan. The subject council performs the approving.
In the passive voice, the subject receives the action: The plan was approved by the council. The subject plan does nothing; it is acted upon.
Voice is independent of tense. A sentence may be past active, past passive, present active, present passive and so on. Confusing the two concepts is common, so it is worth stating plainly: tense tells you when, voice tells you who acts on whom.
The passive is always formed the same way: a form of the verb be, plus the past participle of the main verb. Learning to spot that combination — was written, is being repaired, have been chosen, will be announced — makes identification automatic.
Converting active to passive
The conversion follows three steps, applied in order.
First, move the direct object of the active sentence to the subject position. Second, change the verb to the matching form of be plus the past participle, keeping the original tense. Third, move the original subject to the end, introduced by by, or omit it.
Take The students completed the project. The object is the project, which becomes the subject. The verb completed is past simple, so the passive is was completed. The original subject becomes by the students. The result is The project was completed by the students.
The tense must be preserved exactly. Present simple writes becomes is written. Present continuous is writing becomes is being written. Past simple wrote becomes was written. Past continuous was writing becomes was being written. Present perfect has written becomes has been written. Past perfect had written becomes had been written. Future will write becomes will be written. Modal can write becomes can be written.
Converting passive to active
The process reverses. Identify the agent, whether stated after by or implied, and make it the subject. Change the verb from the be plus participle form to the simple form in the same tense. Move the passive subject to the object position.
The results were announced by the principal becomes The principal announced the results.
Where no agent is given, you must supply a sensible one. The window was broken might become Someone broke the window, and examiners accept a reasonable general agent such as someone, they or a subject implied by the context.
Verbs that cannot be made passive
Only transitive verbs — those taking a direct object — can be made passive, because the passive works by promoting the object to subject. If there is no object, there is nothing to promote.
She arrived early cannot be made passive, because arrived takes no object. The same applies to sleep, go, come, die, happen, appear and exist.
A question asking you to convert an intransitive sentence is testing whether you know this, and the correct response is to explain that the conversion is not possible.
When the passive is the better choice
The passive is often the right choice, and knowing when to use it is as important as being able to form it.
Use it when the agent is unknown: The office was broken into during the weekend.
Use it when the agent is unimportant or obvious: The results will be published in August. Who publishes them adds nothing.
Use it when you wish to emphasise the receiver rather than the doer: Three hundred homes were damaged by the storm places the emphasis on the homes, which is usually what the writer wants.
Use it to maintain focus across sentences: if a paragraph is about a building, keeping the building as the grammatical subject throughout produces smoother writing, even where that requires the passive.
Use it in scientific and formal registers, where the method matters more than the person. The mixture was heated for ten minutes is standard in a report, whereas I heated the mixture would be out of register.
Use it when tact requires the doer to be softened: An error was made in the calculation avoids the accusation carried by You made an error.
When the active is the better choice
For most writing in Paper 2, the active voice is stronger. It is shorter, clearer, and it tells the reader who did what.
Compare It was decided by the committee that the event would be cancelled with The committee cancelled the event. The second version carries the same information in half the words and is markedly more direct.
Overuse of the passive in narrative or persuasive writing flattens the prose and can obscure responsibility. Where you want energy and momentum — in a speech, an article or a story — the active voice serves you better.
The vague passive and its uses
The agentless passive can conceal responsibility, and this is worth understanding both as a writer and as a critical reader.
Mistakes were made reports a fact while hiding who made them. The decision was taken to close the facility does the same. Politicians and institutions use this construction precisely because it removes the actor from view.
In comprehension and summary questions you may be asked to identify this effect, so be ready to say that the passive allows the writer to avoid naming who is responsible. In your own persuasive writing, using it deliberately is a legitimate rhetorical choice — but using it accidentally, and thereby losing clarity, is not.
Worked examples
Example 1: Converting across tenses (4 marks)
Convert each sentence to the passive: The committee is reviewing the applications. The workers have repaired the bridge.
For the first sentence, the object the applications becomes the subject. The verb is present continuous, so the passive form is are being reviewed, plural to agree with the new subject. The result is The applications are being reviewed by the committee.
For the second, the object the bridge becomes the subject. The verb is present perfect, so the passive form is has been repaired, singular to agree with bridge. The result is The bridge has been repaired by the workers.
Note that in both cases the verb agrees with the new subject, not the old one — a step candidates frequently omit.
Example 2: Converting to the active (3 marks)
Rewrite in the active voice: It was announced by the Ministry that the examinations would be rescheduled.
The agent is the Ministry, which becomes the subject. The construction it was announced collapses into the simple verb announced. The subordinate clause also contains a passive, would be rescheduled, whose agent is again the Ministry, so it can be made active too. The clearest version is: The Ministry announced that it would reschedule the examinations. This reduces the sentence from fifteen words to ten with no loss of meaning.
Example 3: Justifying a choice of voice (3 marks)
Explain which voice is more appropriate in each context: a laboratory report describing a procedure, and a newspaper article about a community clean-up.
The laboratory report should use the passive: The solution was heated to eighty degrees Celsius. The identity of the person carrying out the step is irrelevant, the focus belongs on the procedure, and the impersonal passive is the conventional register for scientific writing.
The newspaper article should use the active: Volunteers cleared two tonnes of debris from the beach. The people are the story, the active voice is more immediate and engaging, and naming the doers gives them credit, which is part of the article's purpose.
Common mistakes and how to avoid them
The most frequent conversion error is changing the tense during conversion. The teacher marks the scripts must become The scripts are marked, not were marked. Identify the tense before you convert and check it afterwards.
Students often forget to make the new verb agree with the new subject. When a singular object becomes the subject, the auxiliary must become singular too.
Another common error is attempting to make an intransitive verb passive. If you cannot find a direct object, the conversion cannot be done.
Overusing the passive in creative and persuasive writing is a widespread weakness. If several consecutive sentences contain was or were followed by a participle, rewrite most of them actively.
Finally, candidates sometimes believe the passive is more formal and therefore always better in examinations. It is more formal, but formality is not the same as quality, and unnecessary passives cost clarity marks.
Exam technique for "Active and Passive Voice"
For conversion items in Paper 1, work through the three steps in a fixed order rather than trying to produce the answer whole: move the object, change the verb, relocate the agent. The mechanical approach is faster under pressure and far less error-prone.
Underline the verb phrase before converting. Seeing has been or is being clearly makes the tense obvious, which is where most marks are lost.
When a question asks you to comment on a writer's use of the passive, do not simply identify it. Say what effect it achieves: concealing the agent, emphasising the receiver, or creating an impersonal and objective tone.
In your own Paper 2 writing, favour the active voice by default, and reach for the passive only when you can name the reason. Being able to justify the choice is exactly what distinguishes controlled writing from accidental writing.
Quick revision summary
In the active voice the subject performs the action; in the passive voice the subject receives it. The passive is always formed with a form of be plus a past participle, and voice is independent of tense. To convert to the passive, move the object to subject position, change the verb to be plus participle in the same tense, and move the original subject to the end after by or omit it; the verb must agree with the new subject. To convert to the active, make the agent the subject and supply one if it is missing. Only transitive verbs can be made passive. Choose the passive when the agent is unknown, unimportant, deliberately concealed or less important than the receiver, and in scientific or official registers. Choose the active for directness, energy and clarity, which suits most narrative, persuasive and journalistic writing. The agentless passive conceals responsibility, which is a legitimate rhetorical device when deliberate and a fault when accidental.
