IELTS Speaking Band Descriptors Explained: What Separates Band 6, 7 and 8

How the descriptors are used

The examiner gives you a band from 0 to 9 on each of the four criteria, based on your whole test: Parts 1, 2 and 3 together. Your Speaking band comes from those four, with each carrying equal weight. So a strong Pronunciation can't fully rescue weak Grammar, and one criterion stuck at 5 drags the rest down.

Here's the deal: most candidates think Speaking is about having good answers. The descriptors don't mention ideas at all. They describe how you speak.

Fluency and Coherence

Can you keep talking, and does it hang together?

• Band 6: You're willing to speak at length, but you sometimes lose coherence because of repetition, self-correction or hesitation. You use linking words and discourse markers, though not always appropriately.
• Band 7: You speak at length without noticeable effort or loss of coherence. There may be some hesitation while you search for language, and some repetition or self-correction. Your linking is flexible.
• Band 8: You speak fluently, with only occasional repetition or self-correction. When you hesitate, it's usually to think about what to say, not how to say it. You develop topics coherently and appropriately.

What moves you up: the difference between 6 and 7 is losing the thread less often. Practise Part 2 talks where you finish every bullet without stopping to restart a sentence. The difference between 7 and 8 is why you pause. Pausing to think of an idea is natural. Pausing to find a word is what the examiner notices.

Lexical Resource (vocabulary)

Do you have the words, and do you use them right?

• Band 6: Your vocabulary is wide enough to discuss topics at length and make your meaning clear, even when some choices are inappropriate. You can generally paraphrase.
• Band 7: You use vocabulary flexibly across a range of topics, including some less common and idiomatic words, with awareness of style and collocation. Some choices are still off. You paraphrase effectively.
• Band 8: You use a wide range of vocabulary readily and flexibly to convey precise meaning, including less common and idiomatic items used skilfully, with only occasional inaccuracies.

What moves you up: not rarer words. Better-fitting words. "I was over the moon" about passing a driving test is band 7 vocabulary. The same phrase about a sandwich is a mistake. Collocation (which words naturally go together, like "heavy traffic" rather than "big traffic") is where many 6.5 candidates quietly lose marks.

Grammatical Range and Accuracy

Do you use a mix of structures, and are they correct?

• Band 6: You use a mix of simple and complex structures, but with limited flexibility. You make frequent mistakes with complex structures, though they rarely cause comprehension problems.
• Band 7: You use a range of complex structures with some flexibility. Error-free sentences are frequent, though some mistakes persist.
• Band 8: You use a wide range of structures flexibly. Most sentences are error-free, with only occasional inappropriacies or non-systematic errors.

What moves you up: the 6-to-7 jump is accuracy, not complexity. A candidate who attempts relative clauses and conditionals and gets half of them wrong sits at 6. The same candidate getting most of them right moves to 7. Record yourself, transcribe one minute, and count the sentences with no errors. That number is your grammar score in miniature.

Pronunciation

Can the examiner understand you without effort?

• Band 6: You use a range of pronunciation features with mixed control. You're generally understood throughout, though mispronounced words reduce clarity at times.
• Band 7: You show everything that a band 6 speaker does well, plus some of the band 8 features.
• Band 8: You use a wide range of features: stress, intonation, rhythm and chunking. You're easy to understand throughout, and your accent has minimal effect on intelligibility.

What moves you up: accent isn't the problem. Nobody is marked down for sounding like they're from Delhi or Hanoi. What matters is clarity: word stress in the right place, sentence stress on the important words, and pausing between meaningful chunks instead of mid-phrase.

A very common band 6 pattern

Plenty of candidates stuck around band 6 share the same pattern: fluent enough on familiar Part 1 topics, then noticeably slower and more repetitive in Part 3, where the questions get abstract. If that sounds like you, the fix isn't more vocabulary lists. It's practising the kind of answer Part 3 wants: a view, a reason, an example. Our Part 3 guide walks through it.

How to use the descriptors in practice

1. Record a full practice test: Part 1, a Part 2 cue card, and Part 3 questions. Use real ones from our recent IELTS speaking topics.
2. Listen back once per criterion. Four listens, four questions: did I lose the thread? Did any word choice sound odd? Were my complex sentences correct? Was every word clear?
3. Pick the weakest criterion and practise only that for a week.
