IELTS Band Descriptors Explained: Writing and Speaking

IELTS band descriptors are the published criteria examiners use to mark Writing and Speaking. Each skill has four criteria, each scored from 0 to 9, and together they give your band for that skill. This guide summarises the criteria in plain English and shows what typically separates band 6, band 7 and band 8.

How Writing and Speaking are marked

Examiners mark Writing and Speaking against four criteria each. Every criterion gets a band from 0 to 9, and the band for the skill is based on the four together, so one weak criterion pulls the whole score down.

The tables below summarise the official descriptors in plain English. They describe typical features, not a checklist: examiners match your performance to the band that fits best overall.

The four IELTS Writing criteria

CriterionWhat it measures
Task Achievement (Task 1) / Task Response (Task 2)Whether you cover every part of the task — a clear overview in Task 1, a clear and developed position in Task 2
Coherence and CohesionLogical organisation, paragraphing, and natural, accurate use of linking words and referencing
Lexical ResourceRange and precision of vocabulary, collocation, and control of spelling and word formation
Grammatical Range and AccuracyVariety of sentence structures and how many sentences are free of errors

What separates Writing band 6, 7 and 8

BandTypical features
6Addresses the task, but some parts are underdeveloped or the position is unclear in places; organisation is clear but linking can be mechanical; adequate vocabulary with some errors; a mix of simple and complex sentences, with errors that rarely block meaning
7Addresses all parts with a clear position and extended, supported ideas; logical progression with a range of linking devices; some less common vocabulary used with awareness of style and collocation; frequent error-free sentences
8Covers all parts with well-developed, relevant ideas; information is sequenced logically and paragraphing is well managed; a wide vocabulary used fluently with occasional slips; most sentences are error-free

The four IELTS Speaking criteria

CriterionWhat it measures
Fluency and CoherenceSpeaking at length without unnatural pauses, and linking ideas logically
Lexical ResourceRange of vocabulary, paraphrase, and idiomatic language used appropriately
Grammatical Range and AccuracyRange of sentence structures and how many sentences are free of errors
PronunciationHow easily you are understood, including stress, rhythm and intonation; an accent on its own is not penalised

What separates Speaking band 6, 7 and 8

BandTypical features
6Willing to speak at length but coherence slips through repetition, self-correction or hesitation; enough vocabulary to discuss topics at length; complex structures attempted with frequent errors; generally understood, though some words or sounds are unclear
7Speaks at length without noticeable effort, with some hesitation while searching for language; flexible vocabulary including some less common and idiomatic items; a range of complex structures with frequent error-free sentences; easy to understand throughout
8Speaks fluently with only occasional repetition or self-correction; wide vocabulary used readily and precisely; a wide range of structures, mostly error-free; easy to understand, with the accent having minimal effect

How to use the descriptors to raise your band

  1. Find your lowest criterion — it limits your band more than your strongest one lifts it.
  2. Read the description of the band above your current one and write down the two features you are missing.
  3. Practise only those features for a week, then get a new band estimate on the same kind of task.
  4. In Writing, fix Task Response first: an off-topic or under-length answer caps the band however good the language is.

Task Achievement (Task 1) or Task Response (Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each counts equally.

What are the four IELTS Speaking criteria?

Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, and Pronunciation. Each counts equally.

What is the difference between band 6 and band 7 in IELTS Writing?

A band 7 answer covers every part of the task with a clear position and developed, supported ideas, links them naturally and has frequent error-free sentences. At band 6, ideas are often underdeveloped, linking can be mechanical and errors are more common.

Does my accent affect my IELTS Speaking band?

No. Pronunciation is judged on how easily you are understood and on features such as stress and intonation, not on having a particular accent.
