What is Grammatical Accuracy in IELTS Writing?
Grammatical Accuracy is one of four IELTS Writing criteria measuring your ability to use correct English grammar, including simple and complex sentence structures without errors. Accuracy includes subject-verb agreement, tense consistency, clause construction, and appropriate use of subordination and passive voice — all of which demonstrate advanced grammatical control.
Grammatical Accuracy means constructing sentences with correct grammar, varied sentence structures (complex sentences, passives, conditionals), and no significant errors. For example: 'Although urban populations are growing, infrastructure has not kept pace' uses a subordinate clause, inverted structure and passive construction — all grammatically correct and sophisticated.
Step-by-step worked examples
Weak: Technology is important. It helps people. Some people worry about it. But it has benefits.
Issues: all simple sentences, no complexity, choppy flow.
Strong: While technology poses certain social concerns, its benefits — including enhanced communication and improved access to information — far outweigh the drawbacks.
Fix: Use subordination ('While'), embedded clause (benefits with dashes), passive/complex structure.Weak: Young people use social media. They use it a lot. It affects them. Negative effects are many.
Issues: repetition of simple structure, vague ('many').
Strong: Young people's extensive social media usage, attributed to peer influence and platform design, has been linked to increased anxiety and sleep disruption.
Fix: Complex noun phrase, passive voice ('has been linked'), subordination, precise vocabulary.Weak: Education is good. Teachers teach students. Students learn. This is important.
Issues: monotonous simple sentences, repetition of 'is/are'.
Strong: As educators deliver increasingly sophisticated curricula, students engage with complex concepts, thereby developing critical analytical and collaborative skills essential to workforce readiness.
Fix: Subordination ('As'), complex object, passive agent ('delivering'), varied verb structures.Flashcards

Common mistakes
Overusing complex sentences incorrectly (e.g., 'While the problem exists, therefore solutions are needed'). — Correct: Use subordination correctly: 'While the problem exists, solutions must be implemented' (one main clause + subordinate).
Mixing tenses incorrectly (e.g., 'Young people use social media and had experienced anxiety'). — Correct: Maintain tense consistency: 'Young people use social media and experience anxiety' (both present).
Using passive voice excessively and awkwardly. — Correct: Use passive voice strategically for objectivity or emphasis, not as default.
Ignoring subject-verb agreement, especially with collective nouns or plural subjects. — Correct: Check: singular subject + singular verb; plural subject + plural verb.
FAQ
What is grammatical accuracy and why does it matter in IELTS?
It's using correct grammar and varied structures — one of four Writing criteria (25% each). Advanced accuracy directly raises your band.
Do I need to use complex sentences in every essay?
Not in every sentence, but showing a mix of simple, compound, and complex sentences demonstrates grammatical range (Band 7+).
What's the difference between 'which' and 'that' clauses?
'Which' introduces non-essential (non-restrictive) clauses, set off by commas; 'that' introduces essential (restrictive) clauses with no commas.
How many grammatical errors can I have and still score Band 8?
Zero or possibly one very minor error. Band 7 allows occasional minor errors; Band 6 allows more. Aim for accuracy throughout.
