IELTS Speaking Grammatical Range and Accuracy: Band-by-Band Guide
How IELTS Speaking marks grammar: the range of structures you use and how accurate they are, explained band by band with practical tips.
3 min read · Updated 2026-10-31
Grammatical Range and Accuracy counts for a quarter of your Speaking band. Range is the variety of sentence structures you use; accuracy is how many of your sentences are free from errors. Examiners look at both together.
What examiners listen for
- A mix of simple and complex sentences: subordinate clauses (because, although, when), relative clauses (which, who), conditionals, passives.
- Control of tenses: past for stories, present perfect for experience, future forms for plans, modals for speculation.
- How often your sentences are error-free, especially the longer ones.
- Whether errors get in the way of meaning or are just small slips.
Band by band
The table below is a paraphrase in our own words, not the official wording. For the exact descriptors, read the official IELTS Speaking band descriptors (PDF).
| Band | What it looks like |
|---|---|
| 9 | Uses a full range of structures naturally. Always accurate, apart from the kind of small slips fluent native speakers also make. |
| 8 | Uses a wide range of structures flexibly. Most sentences are error-free, with only occasional mistakes or awkward choices. |
| 7 | Uses a range of complex structures with some flexibility. Error-free sentences are frequent, although some mistakes keep appearing. |
| 6 | Mixes simple and complex structures, but with limited flexibility. Complex forms may often contain errors, but these rarely make the meaning hard to follow. |
| 5 | Produces basic sentences reasonably accurately. Uses only a few complex structures, and these nearly always contain errors and may force the speaker to rephrase. |
| 4 | Mostly uses basic sentences, some of them correct. Subordinate clauses are rare, answers are short and repetitive, and errors are frequent. |
| 3 | Tries to produce basic sentences with limited success, or relies on memorised phrases. Makes many errors outside those phrases. |
| 2 | Cannot produce basic sentence forms. |
| 1 | Nothing that can be rated, apart from memorised language. |
Band 0 is given when a candidate does not attend or does not complete the test.
Features that hold your score down
- Only simple sentences, even if they are all correct. Without complex structures, range stays at a lower band.
- Basic errors that repeat: missing -s on third-person verbs (he go), missing articles, wrong past forms.
- Avoiding tenses you are unsure of, for example telling a whole Part 2 story in the present simple.
- Errors that change meaning, such as confusing I have lived and I lived when describing where you live now.
How to move up a band
- From 5 to 6: start joining ideas with because, although, when and if instead of short separate sentences.
- From 6 to 7: aim for more error-free complex sentences. Pick two or three structures (relative clauses, conditionals, the present perfect) and drill them until they are automatic.
- From 7 to 8: add flexibility: passives, modals of speculation (it might have been), and emphasis (What I enjoy most is…), used naturally rather than to show off.
- At every level: record yourself, transcribe one minute, and correct it. You will quickly find the errors you make most often.
Common mistakes
These examples are original and written for Bee English.
Before (around Band 5):
When I am child, I live in small town. It have one school only. Now I live in city since five years.
After (around Band 7):
When I was a child, I lived in a small town which only had one school. I moved to the city about five years ago, and I've lived here ever since.
The second version fixes the tense errors, adds articles, uses a relative clause (which only had) and handles the present perfect correctly (I've lived here ever since).

Questions people ask
Is it better to use simple grammar correctly or complex grammar with mistakes?
Both range and accuracy are assessed. Using only simple sentences limits your score, so try complex structures, but keep them under control. A few errors in complex sentences are expected at Band 6.
Do small slips count against me?
Occasional slips, the kind fluent speakers also make, are allowed even at the top bands. Repeated errors in basic forms are what hold the score down.
Which structures should I practise for Speaking?
Conditionals, relative clauses, the present perfect, passives, modals for speculation and comparatives. These come up naturally in Parts 2 and 3.
