Grammar in IELTS Speaking: How Much It Matters and What to Use

Grammatical Range and Accuracy is exactly 25% of your Speaking band, the same weight as Fluency and Coherence, Lexical Resource, and Pronunciation. It is not a minor add-on — a candidate who speaks fluently and with a rich vocabulary but makes frequent basic grammar errors will not reach Band 7 or above, because the four criteria are scored independently and then combined.

What differs from Writing is the standard of 'accuracy' itself. Spoken English is produced in real time, without the chance to edit, so examiners expect and accept features that would be marked down in an essay: contractions, minor hesitations, and the occasional self-corrected slip, provided they don't happen so often that they interrupt communication.

Part 1 questions are short and personal — hobbies, hometown, daily routine — and the grammar they invite is correspondingly simple: present simple for habits, past simple for past events, present perfect for experience. The examiner is listening for reliability here far more than ambition; a Part 1 answer built entirely from short, accurate sentences with the occasional 'and' or 'because' is a completely appropriate Band 6–7 response.

The most valuable habit for Part 1 is the two-step pattern of introducing an experience with the present perfect and then giving the detail in the past simple: 'I've tried surfing once — I took a lesson in Bali and fell off constantly.' That single tense switch, done accurately, signals more control than a much longer answer with tense mistakes.

• I've tried surfing once — I took a lesson in Bali and fell off constantly.(present perfect introduces, past simple narrates the detail)

The two-minute long turn is fundamentally a narrative, so past simple and past continuous carry most of the weight — 'I was waiting at the bus stop when I first met her.' One well-placed past perfect sentence adds background without overloading the story: 'By the time I arrived, everyone else had already left.'

A single relative clause or conditional dropped naturally into the story — 'It's a place that changed my whole perspective' — demonstrates range without derailing the narrative flow that examiners are also scoring under Fluency and Coherence. Resist the urge to cram in every structure you know; one or two accurate additions beat five attempted ones.

• By the time I arrived, everyone else had already left.(one background past perfect sentence inside a past-simple story)

Part 3 asks you to generalise, speculate, and evaluate — exactly the territory of conditionals, modal verbs of deduction, and the passive voice. 'If governments invested more in public transport, congestion would probably fall' reasons about a hypothetical policy; 'It's often assumed that older generations are less comfortable with technology, but I'm not sure that's still true' distances a generalisation while adding your own opinion.

Modals carry a lot of the nuance examiners are listening for at this stage: 'might', 'could', and 'may well' hedge a claim appropriately, while 'must have' and 'can't have' express deduction about the past. Candidates who answer every Part 3 question with flat present-simple statements ('People like technology') miss the range this section is specifically designed to draw out.

• If governments invested more in public transport, congestion would probably fall.(second conditional for hypothetical policy reasoning)
• It's often assumed that older generations are less comfortable with technology, but I'm not sure that's still true.(distancing passive plus a personal hedge)

Many candidates panic when they hear themselves make a mistake mid-sentence and either freeze or plough on regardless. Both reactions cost more marks than a brief, natural self-correction: 'She go— she goes to the gym most mornings' shows an examiner that you noticed and fixed a subject-verb agreement slip in real time, which is closer to native-speaker performance than either freezing or an uncorrected error.

The Band 9 descriptor explicitly allows for 'slips characteristic of native speaker speech' — and self-correction is exactly that. The goal is not to eliminate every disfluency but to make sure the version that survives, after any correction, is grammatically accurate.

• She go— she goes to the gym most mornings.(a natural self-correction, not a penalised error)

Frequent basic errors — wrong verb forms, missing articles, subject-verb disagreement in simple sentences — are penalised because they suggest a genuine gap rather than a performance slip, and they appear explicitly in the lower band descriptors. A single dropped article in ninety seconds of otherwise accurate speech, by contrast, is the kind of 'occasional inappropriacy' the Band 8 descriptor tolerates.

What examiners are trained to listen for is a pattern across the whole interview, not a scorecard of individual mistakes. A candidate who corrects themselves, varies sentence length, and only occasionally slips will consistently outscore one who speaks without a single hesitation but repeats the same basic error in every second sentence.
