IELTS Speaking Band Descriptors Explained: What Examiners Look For in Each Criterion

The IELTS Speaking band descriptors are the official scale examiners use to rate you. They describe, for each of four criteria, what a speaker at each band from 0 to 9 can do. If you know what separates band 6 from band 7 in each criterion, you can stop practising “more English” and start practising the specific things that move your score.

This guide walks through the official descriptors criterion by criterion, shows the band 6, 7 and 8 differences side by side, and explains how the four criteria become your Speaking score. Facts below are checked against the official IELTS pages and the descriptors PDF (links in Sources) as of October 2026.

How IELTS Speaking is scored

Certificated IELTS examiners assess your speaking throughout the test against four criteria:

1. Fluency and Coherence
   
2. Lexical Resource (vocabulary)
   
3. Grammatical Range and Accuracy
   
4. Pronunciation
   

According to IELTS, each criterion carries equal weighting, and the average gives your Speaking score. Speaking results are reported on the 0–9 band scale, in whole or half bands (for example 6.0, 6.5 or 7.0).

Two notes printed on the official descriptors matter more than most candidates realise:

• “A candidate must fully fit the positive features of the descriptor at a particular level.” You do not get band 7 for one impressive idiom. You get it when your speech shows all the band 7 features.
  
• “A candidate will be rated on their average performance across all parts of the test.” One weak answer does not ruin your score, and one brilliant answer does not make it. Consistency across Parts 1, 2 and 3 is what counts.
  

The Speaking test is the same for IELTS Academic and IELTS General Training, so the same descriptors apply to both. For the structure and timing of each part, see our IELTS Speaking test format guide.

The overall IELTS band score (and how it rounds)

Your overall IELTS band is the average of your four section scores (Listening, Reading, Writing and Speaking), rounded to the nearest whole or half band. IELTS publishes the rule for averages that fall in between: an average ending in .25 rounds up to the next half band, and one ending in .75 rounds up to the next whole band. For example, 6.5 + 6.5 + 5.0 + 7.0 = 25.0, an average of 6.25, which becomes an overall band of 6.5.

The IELTS pages do not publish how an in-between average of the four Speaking criteria is rounded, so be wary of guides that claim to know it exactly.

Criterion 1: Fluency and Coherence

This criterion covers two things: how smoothly you keep talking (fluency) and how clearly your ideas connect (coherence).

What changes from band 6 to band 8 (official wording in quotes):

• Band 6: “Able to keep going and demonstrates a willingness to produce long turns.” But “coherence may be lost at times as a result of hesitation, repetition and/or self-correction”, and discourse markers are used “though not always appropriately”.
  
• Band 7: “Able to keep going and readily produce long turns without noticeable effort.” Some hesitation or self-correction may happen mid-sentence while you search for language, but “these will not affect coherence”. There is “flexible use of spoken discourse markers, connectives and cohesive features”.
  
• Band 8: “Fluent with only very occasional repetition or self-correction.” Hesitation is mostly about what to say, not how to say it: “most will be content related”. Topic development is “coherent, appropriate and relevant”.
  

What this means in practice:

• The jump from 6 to 7 is about effort. At band 6 the listener can hear you working; at band 7 long answers come readily.
  
• Pausing is not penalised in itself. A pause to think about an idea is natural (and at band 8 that is the main kind of pause). A pause in the middle of a phrase to find a basic word is what pulls the score down.
  
• “Coherence” means the listener can follow your answer: a clear point, a reason, an example, then a link back. Connectives such as however, on top of that or the main reason is help, but only when they fit. Overusing them is a band 5 feature: the band 5 descriptor mentions “overuse of certain discourse markers, connectives and other cohesive features”.
  

How to practise it: answer Part 1 questions in 3–4 sentences (answer, reason, example), record a 2-minute Part 2 talk every day, and listen for where you stop mid-sentence. Our fluency tips guide has drills for each of these.

Criterion 2: Lexical Resource

Lexical Resource is your vocabulary: how wide it is, how precisely you use it, and whether you can paraphrase when you do not know a word.

• Band 6: “Resource sufficient to discuss topics at length.” Word choice “may be inappropriate but meaning is clear”, and you are “generally able to paraphrase successfully”.
  
• Band 7: “Resource flexibly used to discuss a variety of topics.” There is “some ability to use less common and idiomatic items and an awareness of style and collocation”, even though “inappropriacies occur”, and “effective use of paraphrase as required”.
  
• Band 8: “Wide resource, readily and flexibly used to discuss all topics and convey precise meaning”, with “skilful use of less common and idiomatic items despite occasional inaccuracies in word choice and collocation”.
  

What this means in practice:

• Collocation beats rare words. “Make a decision”, “a heavy rain shower” and “a steep learning curve” show control. A rare word in the wrong collocation shows the opposite.
  
• Idioms are optional, not required. The descriptors mention “idiomatic items” from band 7 up, but a memorised idiom forced into an answer sounds memorised. Natural, topic-specific phrasing (“commute”, “a nine-to-five job”, “work-life balance”) is safer.
  
• Paraphrase is a skill examiners listen for. If you forget a word, describing it (“the thing you use to… “) keeps you fluent and shows lexical flexibility.

Criterion 3: Grammatical Range and Accuracy

This criterion rates two things together: the range of structures you use and how accurate they are.

• Band 6: “Produces a mix of short and complex sentence forms and a variety of structures with limited flexibility.” Errors “frequently occur in complex structures” but “rarely impede communication”.
  
• Band 7: “A range of structures flexibly used. Error-free sentences are frequent.” Simple and complex sentences are used effectively “despite some errors”, and “a few basic errors persist”.
  
• Band 8: “Wide range of structures, flexibly used. The majority of sentences are error free.” Occasional “non-systematic errors” occur.
  

What this means in practice:

• Band 7 does not require perfect grammar. It requires that error-free sentences are frequent and that you use complex structures (conditionals, relative clauses, passives, a mix of tenses) flexibly, not just once.
  
• The word “systematic” matters at band 8. A one-off slip is fine; the same mistake every time (for example, always dropping the past tense ending) is a pattern the examiner will notice.
  
• Range shows up naturally in Part 3, where you explain, compare and speculate: “If cities invested more in public transport, fewer people would need a car” is a natural place for a conditional.
  

Criterion 4: Pronunciation

Pronunciation is about how easy you are to understand, not about sounding British or American.

• Band 6: “Uses a range of phonological features, but control is variable.” Individual words may be mispronounced, but this “causes only occasional lack of clarity”, and you “can generally be understood throughout without much effort”.
  
• Band 7: the descriptor reads “displays all the positive features of band 6, and some, but not all, of the positive features of band 8”.
  
• Band 8: “Uses a wide range of phonological features to convey precise and/or subtle meaning”, with appropriate rhythm and flexible stress and intonation across long utterances. You “can be easily understood throughout” and “accent has minimal effect on intelligibility”.
  

What this means in practice:

• Accent is not the target; intelligibility is. Even band 9 says “accent has no effect on intelligibility”, not “no accent”.
  
• “Phonological features” means more than individual sounds: word stress (PHO-to-graph vs pho-TO-gra-pher), sentence stress on the important words, chunking words into natural groups, and intonation that shows whether you are finishing or continuing.
  
• Speaking very fast is a common band 6 problem: the band 6 descriptor mentions rhythm “affected by a lack of stress-timing and/or a rapid speech rate”.
  

Our guide to why pronunciation is the most underrated IELTS skill covers stress and rhythm practice in detail.

Common misconceptions

“You need a native accent for a high score.” No. The descriptors rate intelligibility and the use of stress, rhythm and intonation. Band 9 explicitly allows an accent that “has no effect on intelligibility”.

“Speaking fast means fluent.” No. Fluency in the descriptors is about keeping going without effort and staying coherent. A rapid speech rate is mentioned as a problem at band 6.

“Band 7 needs perfect grammar.” No. “A few basic errors persist” is part of the band 7 grammar descriptor. What band 7 needs is frequent error-free sentences and flexible complex structures.

“Memorised answers score well.” The band 3 grammar descriptor mentions “apparently memorised utterances”, and examiners rate your average performance across the whole test. Memorised scripts tend to break down in Part 3’s follow-up questions.

“Your ideas are scored.” The criteria rate your language, not your opinions. A simple, clearly explained idea in good English scores better than an ambitious idea you cannot express.

How to use the descriptors in your practice

1. Download the official descriptors (link below) and keep them open while you review recordings.
   
2. Record full answers, not single sentences: a Part 1 answer, a 2-minute Part 2 talk and two Part 3 answers.
   
3. Rate one criterion at a time. Listen once for hesitation mid-sentence, once for vocabulary, once for grammar errors that repeat, once for stress and clarity.
   
4. Find your lowest criterion. Your Speaking score is an average, so raising your weakest criterion by a band moves the score more than polishing your strongest.
   
5. Practise the part that exposes that criterion. Fluency problems show up in Part 2; grammar range shows up in Part 3; vocabulary range shows up across Part 1 topics.
   
6. Check the usual traps in our list of common IELTS Speaking mistakes.
