IELTS Speaking band descriptors explained in plain words

What IELTS Speaking examiners listen for: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, and Pronunciation, in plain words.

How Speaking is marked

The examiner assesses your performance across the whole test, not part by part, against four criteria of equal weight:

The four scores are combined into your Speaking band. The official descriptors are on ielts.org. This page explains each criterion in our own words as a study aid; it does not replace the official wording.

Fluency and Coherence

Fluency is about keeping going: speaking at a natural pace without long pauses, frequent restarts or heavy repetition. Coherence is about making sense: ideas that connect, answers that stay on the question, and points that are developed rather than left hanging.

• Lower bands: long pauses, short answers, and ideas that are hard to link together.
• Middle bands: willing to speak at length, but with some hesitation, repetition or self-correction, and linking that can feel mechanical.
• Higher bands: speaks at length with ease. Any pauses are to think about ideas, not to search for words or grammar. Ideas are developed and connected naturally.

Pausing to think is normal. Native speakers do it too. What lowers the score is hesitation caused by not finding the language.

Exam tip: natural spoken linking phrases help more than written ones. "The thing is ...", "Mind you ..." and "That said ..." sound more natural in conversation than "Furthermore".

Lexical Resource

This criterion looks at the range and precision of your vocabulary, and how well you cope when you do not know a word.

• Lower bands: enough words for familiar topics only; frequent wrong word choices.
• Middle bands: can discuss a range of topics, uses some less common words, and can usually get around gaps by explaining in other words, known as paraphrasing.
• Higher bands: uses vocabulary flexibly and precisely, including idiomatic language and natural word combinations, with only occasional slips.

Idioms help only when they fit. An invented example: saying a new job was "a steep learning curve" is natural and precise. Forcing in "it's raining cats and dogs" when talking about a quiet afternoon is not.

Exam tip: if a word escapes you, describe it. "The thing you use to open a bottle of wine" shows the paraphrasing skill the examiner wants to hear.

Grammatical Range and Accuracy

Range is the variety of structures you use: complex sentences, conditionals, relative clauses, different tenses and so on. Accuracy is how many of your sentences are free of error.

• Lower bands: mostly short, simple sentences, with frequent errors.
• Middle bands: a mix of simple and complex structures; errors are noticeable but meaning is usually clear.
• Higher bands: a wide range of structures used naturally, with most sentences error-free.

The three parts give you different chances to show range. Part 2 invites past tenses when describing an experience. Part 3 invites conditionals and speculation, such as "If schools taught more practical skills, young people might ..."

Pronunciation

This is about how easy you are to understand, not whether you sound like a native speaker. A clear accent from any country can score highly.

The examiner listens for:

• individual sounds pronounced clearly enough not to cause confusion;
• word stress, such as the difference between "PHOtograph" and "phoTOgraphy";
• sentence stress and rhythm, so the important words stand out;
• intonation, the rise and fall that shows questions, lists, contrast or feeling;
• chunking, grouping words into natural phrases rather than saying each word separately.

• Lower bands: frequent problems that make the listener work hard, or parts that cannot be understood.
• Middle bands: generally understood, with some features used well but not consistently; some words or sounds cause strain.
• Higher bands: easy to understand throughout, with a full range of features used naturally.

Exam tip: record yourself answering a practice question, then listen back. Problems with stress and rhythm are much easier to hear in a recording than while speaking.

Common misunderstandings

• "Big words get high scores." Only if they are used correctly and naturally.
• "My accent will lower my score." Clarity matters, not the accent itself.
• "I must never pause." Pausing to think about ideas is natural; hesitating over basic words is what counts against you.
• "Memorised answers sound fluent." Examiners recognise them, and they can lower the scores because they do not reflect your real ability.

Key points

1. Four criteria, equally weighted, assessed across the whole test.
2. Fluency is keeping going; coherence is making sense.
3. Paraphrasing when you lack a word is a skill the examiner credits.
4. Grammar is judged on both range and accuracy.
5. Pronunciation means being easy to understand, not sounding native.
6. Check ielts.org for the official descriptors.
