The IELTS Speaking band descriptors are the document examiners use to decide your Speaking score. Instead of a single overall impression, examiners rate your performance against four named criteria and combine those scores into one band. Many candidates prepare for months without ever reading this document, so they focus on general fluency without knowing exactly what raises or lowers a score.
This guide explains the four assessment criteria in plain language, what typically separates one band from the next, and where to find the official public version so you can check it for yourself.
The four Speaking assessment criteria
Examiners score four criteria, and each one contributes equally to your final Speaking band.
- Fluency and Coherence: how smoothly you speak, whether you can keep talking without long pauses, and whether your ideas connect logically with appropriate linking words.
- Lexical Resource: the range and precision of your vocabulary, including your ability to paraphrase when you do not know a specific word.
- Grammatical Range and Accuracy: the variety of sentence structures you use and how accurately you use them.
- Pronunciation: how clearly you can be understood, including your use of stress, intonation and individual sounds.
Because the four criteria carry equal weight, a weakness in one area, such as a narrow vocabulary, can hold back your overall Speaking band even if your grammar is strong.
How the four scores become one Speaking band
The examiner assigns a score for each of the four criteria, and the Speaking band is the average of the four, rounded according to IELTS rounding rules. For example, scores of 7, 6, 7 and 6 across the four criteria average to 6.5, which becomes the reported Speaking band.
Because the calculation is an average, no single criterion can be ignored. A candidate with excellent pronunciation but limited vocabulary will not automatically receive a high overall band.
How the IELTS Speaking band descriptors apply across the three test parts
The same four criteria are used throughout the Speaking test, but the three parts give different opportunities to show them.
- Part 1 involves short answers to familiar questions, so fluency and basic vocabulary are easy to observe early on.
- Part 2 asks for a longer, largely uninterrupted turn on a given topic, which shows coherence and range of vocabulary over a sustained stretch of speech.
- Part 3 involves more abstract discussion questions, which tend to reveal grammatical range and the ability to develop and justify opinions.
Because scoring is based on your performance across the whole test, a strong Part 2 does not offset a Part 1 or Part 3 that shows limited range.
What each band level generally looks like
The descriptions below summarize, in plain language, the kind of performance associated with common band levels. They are a simplified overview, not the wording of the official document, which you should read directly for exact criteria.
IELTS Speaking band descriptors: Band 4 to 5
Speech includes frequent pauses and hesitation, vocabulary is limited to familiar topics, sentence structures are mostly simple, and pronunciation problems can make parts of the speech difficult to follow for the listener. Candidates at this level often rely on the examiner’s questions to keep the conversation moving, rather than developing ideas independently.
IELTS Speaking band descriptors: Band 6
The candidate is willing to speak at length and generally keeps a conversation going, though coherence can slip when they lose their train of thought. Vocabulary is sufficient for familiar and some unfamiliar topics but lacks precision at times, grammar shows a mix of simple and more complex structures with limited flexibility, and pronunciation is understandable despite some inconsistencies.
Band 7
Speech flows with little noticeable effort, supported by a wider range of linking words used more naturally. Vocabulary allows some flexibility and paraphrasing, grammar includes a broader range of structures with errors that rarely affect meaning, and pronunciation stays clear with only occasional lapses.
Band 8 to 9
Speech is fluent with only occasional self-correction, vocabulary is wide and used precisely, including less common expressions, grammar is accurate across a wide range of structures, and pronunciation uses natural stress and intonation that remains clear throughout.
The public version of the band descriptors
Candidates sometimes ask about the IELTS Speaking band descriptors public version because IELTS publishes a version intended for candidates and teachers, separate from the fuller internal version examiner training uses. The public version still lists the four criteria and describes each band level, and it is the document most study guides refer to when they explain scoring.
Where to find the official document
Many candidates search for the IELTS Speaking band descriptors official source rather than a third-party summary, since paraphrased versions can leave out details or use different wording from band to band. The official IELTS Speaking band descriptors pdf is published on ielts.org and is also referenced by the test providers, including IDP. If you search for IELTS Speaking band descriptors IDP, you will generally be pointed to the same public version, since IDP and the other IELTS partners use the same descriptors rather than separate scoring documents.
Because guides are sometimes labelled with a year, such as an IELTS Speaking band descriptors 2025 reference, or promoted as a new version, it is worth confirming on ielts.org that you are reading the current public version rather than a summary based on an older copy.
A worked example of the band calculation
Suppose an examiner rates a candidate as follows: Fluency and Coherence 7, Lexical Resource 6, Grammatical Range and Accuracy 6, Pronunciation 7. The average of these four scores is 6.5, so the candidate’s reported Speaking band is 6.5. If the same candidate improved Lexical Resource to 7 while the other three scores stayed the same, the average would rise to 6.75, which rounds up to a Speaking band of 7.0. This shows why working on a single weaker criterion, rather than trying to improve everything at once, can move the overall band.
How to use the IELTS Speaking band descriptors
- Read the criteria before you practice, so you know what an examiner is listening for beyond general fluency.
- Record a practice answer and check it against each criterion separately, rather than judging your speaking as a single impression.
- Target your weakest criterion first. If your grammar is already varied but your vocabulary is repetitive, prioritize paraphrasing practice over grammar drills.
- Practice linking ideas, not just longer answers. Coherence depends on how ideas connect, not only on how much you say.
- Get feedback from someone familiar with the descriptors, since self-assessment against four technical criteria is difficult without training.
Common misunderstandings
- Assuming pronunciation only means accent. The descriptors focus on clarity and the effective use of stress and intonation, not on sounding like a particular native accent.
- Confusing fluency with speed. Speaking quickly with frequent hesitation scores lower than speaking at a natural pace with fewer breakdowns.
- Ignoring coherence. Using a wide vocabulary does not compensate for ideas that are hard to follow.
- Treating the four criteria as separate scores you can average yourself from a single guess. Only a trained examiner, or detailed self-review against each descriptor, gives a meaningful estimate.
- Memorizing long answers. Examiners are trained to notice rehearsed or memorized language, and it can affect how naturally your fluency and coherence come across.
The IELTS Speaking band descriptors show exactly what examiners are listening for across fluency and coherence, vocabulary, grammar and pronunciation. Reading the public version, rather than relying only on general tips, helps you identify which criterion is limiting your score and focus your practice accordingly. Confirm you are using the current version from ielts.org, since guides are sometimes based on outdated summaries.

Frequently asked questions about IELTS Speaking band descriptors
Are the Speaking band descriptors the same for Academic and General Training?
Yes. The Speaking test and its band descriptors are the same for both versions of IELTS. Academic and General Training differ in the Reading and Writing papers, not in Speaking.
Where can I read the official IELTS Speaking band descriptors?
The public version is published on ielts.org, and the same descriptors are referenced by test providers such as IDP and the British Council. Reading it directly is more reliable than relying only on a third-party summary.
Can strong pronunciation make up for a limited vocabulary in Speaking?
Not on its own. The four criteria are equally weighted and averaged, so a strong score in one area does not override a weak score in another. Improving your overall Speaking band usually means identifying and working on your weakest criterion specifically.
