There’s a quiet skill that decides more IELTS bands than most candidates realise, and it isn’t grammar or vocabulary in the way you’d expect. It’s paraphrasing — the ability to take an idea and say it again in different words without bending its meaning. Every part of the test rewards it. In Writing you’re expected to reword the task prompt rather than copy it. In Speaking, the examiner is listening for whether you can express the same thought in more than one way. Get paraphrasing right and the whole test starts to feel easier; get it wrong and you leak marks in places you never even see.
Why examiners care so much
Copying the question wastes words and tells the examiner nothing about you. When you write “Some people think that children should start school at a very young age” straight off the task sheet, the marker mentally deletes it — those words don’t count toward your response, and they show off no language of your own. The band descriptors reward a wide range of vocabulary and the flexibility to use it. Paraphrasing is how you prove both in your very first sentence. It’s also how you stop repeating the same word ten times across an essay, which is one of the quickest ways to cap your Lexical Resource score at band 6.
Change the words, not the meaning
This is the rule that matters most, and it’s exactly where people trip. Paraphrasing means finding a different way to say the same thing — not a slightly different thing. “Cars cause pollution” and “Cars are a major source of air pollution” are both fine; the second just says it more precisely. But “Cars sometimes cause a little pollution” is not a paraphrase — you’ve quietly changed the claim. Examiners notice instantly when a reworded sentence no longer matches the original idea, and in Writing Task 1 especially, misreporting the data costs you Task Achievement marks. Your job is to lock the meaning and change everything around it.
The four tools that do the work
You don’t need dozens of techniques. Four will cover almost everything. Synonyms: swap individual words for ones that mean the same — “young people” for “teenagers,” “benefits” for “advantages.” Just check the synonym genuinely fits the context, because “cheap” and “affordable” aren’t always interchangeable. Word form: change the part of speech, so “pollution increased” becomes “there was an increase in pollution” — a powerful move, because it forces the rest of the sentence to reshape. Voice: switch between active and passive, turning “the government built the bridge” into “the bridge was built by the government” when you want to shift the emphasis. Sentence structure: combine or split clauses, so “Because prices rose, demand fell” becomes “The rise in prices led to a fall in demand.” The strongest paraphrases usually use two or three of these tools at once, not synonyms alone.
Where paraphrasing goes wrong
The most common mistake is reaching for a thesaurus and dropping in a word you don’t actually know. Writing “the juvenile populace” instead of “young people” doesn’t sound advanced — it sounds wrong, and it pulls your score down. Stick to vocabulary you can use accurately. The second trap is trying to replace every single word until the sentence collapses under its own weight; some words, like “children” or “water,” have no natural synonym and are better left alone. And keep an eye on your grammar — when you change a word’s form, the tense and the linking words around it often have to change too, and a half-finished paraphrase reads worse than no paraphrase at all.
How to build the skill
Paraphrasing improves through deliberate, repetitive practice, not by hoping it turns up on test day. Take any sentence — a news headline, an old task prompt, anything — and rewrite it three different ways, leaning on a different tool each time. Then read the original and your version side by side and ask one question: does it mean exactly the same? Keep a running list of reliable synonyms for the topics that come up again and again in IELTS — education, environment, technology, health — so the right word is ready when you need it. Do this for ten minutes a day over a few weeks and you’ll stop reaching for the thesaurus, because the alternatives will already be sitting in your head.
Paraphrasing is a small habit with an outsized effect on your band, and it’s very trainable with the right feedback — someone who can tell you the moment a reworded sentence has quietly shifted its meaning. That’s exactly what the IELTS preparation courses at Kensington English focus on, with native teachers who mark your writing and speaking against the real band descriptors so you always know where your marks are going.
