How the IELTS Speaking band descriptors work

In this guide

Your Speaking band is not a feeling the examiner has about your English. It comes from a published scale, the Speaking band descriptors, which describes performance at each band from 0 to 9 under four criteria. This guide explains how the scale is used, what the four criteria mean in practice, and what usually separates Band 6 from Band 7.

Four criteria, equal weight

The examiner rates you on four criteria:

  • Fluency and coherence: how easily you keep going, and how clearly your ideas connect.
  • Lexical resource: the range and precision of your vocabulary.
  • Grammatical range and accuracy: the variety of structures you use, and how often they are correct.
  • Pronunciation: how easy you are to understand, and how well you use features such as stress, rhythm and intonation.

The four carry equal weight. The examiner gives a band for each one, and your Speaking band is worked out from all four, reported as a whole or half band. A very strong Lexical resource cannot fully make up for weak Grammatical range and accuracy, and the reverse is also true. That is the first useful thing to know: your weakest criterion holds your overall band down more than your strongest one lifts it.

The test is marked as a whole

The examiner does not give a separate band for Part 1, Part 2 and Part 3. They listen across the whole test, roughly eleven to fourteen minutes, and decide which band description fits your performance best for each criterion.

So a weak start is not fatal, and a strong Part 1 is not enough. Many candidates who sound comfortable in Part 1 find that their grammar and vocabulary narrow in Part 3, when the questions move from "Do you like reading?" to "Why do some people stop reading for pleasure as adults?" Practise Part 3 at least as much as Part 1.

Fluency and coherence

This criterion asks two questions: can you speak at length without long pauses, and do your ideas follow on from each other?

At Band 6, a candidate is willing to speak at length but sometimes loses coherence through repetition, self-correction or hesitation, and uses linking words in a way that is not always appropriate. At Band 7, the candidate speaks at length without noticeable effort, and when they hesitate it is usually to find the right idea or word, not to rescue a sentence. Linking is flexible: not only "and", "but", "because", but "what I mean is", "that said", "the main reason is".

The common misunderstanding is that fluency means speed. It does not. A calm pace with clear connections between ideas is more fluent, in the descriptors' sense, than fast speech that keeps restarting.

Lexical resource

This is about whether you have the words for the topic and use them precisely. At Band 6, vocabulary is wide enough to discuss topics at length and make the meaning clear, even when some choices are not quite right. At Band 7, vocabulary is used flexibly across a variety of topics, including some less common and idiomatic items, with awareness of style and collocation. Both bands expect you to paraphrase: to find another way to say something when the exact word does not come.

Collocation is where Band 6 and Band 7 most often differ. "Make a decision", "a heavy workload", "keep in touch" are not rare words, but using them naturally shows control. A candidate who reaches for rare words and gets the collocation wrong usually does worse than one who uses common words in the right combinations.

Grammatical range and accuracy

Range and accuracy are judged together. At Band 6, a candidate uses a mix of simple and complex structures, with limited flexibility, and makes frequent mistakes with complex structures, though these rarely make the meaning unclear. At Band 7, a range of complex structures is used with some flexibility, and error-free sentences are frequent, though some errors remain.

Two habits move people from 6 to 7. The first is using complex structures where they belong naturally: a relative clause to add detail, a conditional to speculate in Part 3, the present perfect to connect past and present. The second is accuracy in the basics that occur in almost every sentence: verb tenses, articles, plural endings, subject-verb agreement. A small error repeated twenty times in a test is heard twenty times.

Pronunciation

Pronunciation is not about sounding British, American or anything else. A noticeable accent from your first language is not a problem in itself. What the descriptors measure is how easily the listener understands you and how well you use the features of spoken English: word stress, sentence stress, rhythm, intonation and how words join together.

At Band 6, the candidate uses a range of these features with mixed control and can generally be understood, though some words or sounds are mispronounced and reduce clarity at times. Higher bands describe speech that is easy to follow throughout, where stress and intonation help carry the meaning. In practice, the fastest gains usually come from word stress on common long words and from pausing at the end of an idea rather than in the middle of one.

Reading the descriptors as a learner

The descriptors were written for trained examiners, so a few habits help when you read them yourself:

  • Read two bands side by side. Compare your current band and the one above it, criterion by criterion. The differences in wording are your study plan.
  • Notice the qualifiers. Words like "some", "frequent", "generally" and "at times" carry the meaning. Band 6 and Band 7 often describe the same skill and differ in how consistently it appears.

Which criterion to practise first

Start with the lowest of your four. If you do not know which that is, record yourself answering three Part 3 questions and check the transcript for the same error appearing more than twice. Repeated errors in tense or articles point to Grammatical range and accuracy; long pauses and restarts point to Fluency and coherence; the same few adjectives used for everything point to Lexical resource.

Then work on that one criterion for a week, in short daily sessions, and check again. Spreading effort evenly across all four feels thorough, but because the criteria are equally weighted, lifting the weakest one is usually the quickest way to lift the overall band.

BandNine's report follows the same four criteria. After a mock test it gives an estimated band for each, quotes the words from your answers that support it, and says so when there is not enough evidence to estimate one. These are AI practice estimates, not official IELTS results, and the only band that counts is the one from your test centre. Read the official public band descriptors on the IELTS website alongside any practice tool you use.

Questions people ask

Are the four IELTS Speaking criteria weighted equally?

Yes. Fluency and coherence, Lexical resource, Grammatical range and accuracy, and Pronunciation each get a band, and the Speaking band is worked out from all four, reported as a whole or half band.

Does my accent lower my IELTS Speaking band?

No. The descriptors measure how easily the listener understands you and how you use stress, rhythm and intonation. A noticeable first-language accent is not a problem in itself.
