IELTS Speaking Band Descriptors Explained: What Separates

Your IELTS Speaking score is the average of four criteria, each worth 25%. The examiner scores them across all three parts — Part 2 does not decide Fluency alone, and Part 3 does not decide Grammar alone.

The criteria below follow the official IELTS Speaking band descriptors published by the test owners (ielts.org scoring in detail).

Most candidates stuck at 6.5 score 7 on two criteria and 6 on the other two. This guide shows exactly what each level looks like and how to fix the weak ones.

Criterion	Weight	Core question
Fluency & Coherence	25%	Can you talk at length, smoothly, with logical flow?
Lexical Resource	25%	Is your vocabulary wide, precise, and natural?
Grammatical Range & Accuracy	25%	Do you use varied sentences accurately?
Pronunciation	25%	Are you easy to understand with natural stress and rhythm?

Jump to Criterion 1: Fluency and CoherenceCriterion 1: Fluency and Coherence

The most common reason for Band 6. Note: fluency means smooth continuity, not speed. Fast but incoherent speech scores lower than moderate-paced, well-linked speech.

Band 6 vs 7 vs 9:

Band	Fluency	Coherence
Band 6	Willing to talk at length, but noticeable hesitation, repetition, self-correction	Linking is basic ("and," "because," "so"); ideas sometimes disconnected
Band 7	Talks at length with only occasional hesitation; some self-correction remains	Range of connectives used flexibly; ideas logically sequenced
Band 9	Effortless, natural flow; only content-related hesitation (thinking of ideas, not words)	Fully coherent, sophisticated discourse markers, effortless topic development

Three fixes that move Band 6 to 7:

1. Replace silent pauses with natural fillers. "That's an interesting question...", "Well, I'd say...", "Let me think..." — one per answer is natural; silence while searching for words is penalised.
2. Extend every Part 1 answer to 3-4 sentences. One-sentence answers force the examiner to drag content out of you, which reads as dysfluency. Answer + reason + example + contrast. Our Part 1 topics guide gives extendable sample answers.
3. Structure Part 2 with past-present-future. "When it happened / what it was like / how I felt then / what I think now." A built-in timeline eliminates the mid-talk freeze that causes repetition. Drill it with 2026 cue cards.

Jump to Criterion 2: Lexical ResourceCriterion 2: Lexical Resource

Same principle as Writing: collocation and precision beat rare words. But Speaking adds one thing Writing does not — idiomatic language used naturally.

What examiners reward:

• Topic vocabulary with precision: "commute," "deadline," "workload" used correctly beats "fascinating phenomenon" used wrongly.
• Natural idioms, sparingly: one genuine idiom per part ("burnt out," "a blessing in disguise") signals Band 7+. Five forced idioms per answer signals memorisation and caps you at 6.
• Paraphrase under pressure: when you forget a word, describing it ("the machine that washes dishes" for dishwasher) protects your score — the descriptor explicitly rewards this. Our paraphrasing techniques guide trains exactly this reflex.
• Less common items: "devastating," "thrive," "controversial" — used accurately, not dropped in.

The Band 6 trap: memorised answers. Examiners are trained to detect them, and the penalty hits Fluency and Vocabulary simultaneously. Build from our Speaking vocabulary bank instead of scripts.

Hear the difference in our Band 9 sample answers — notice how ordinary most of the vocabulary is, and how precise the collocations are.

Jump to Criterion 3: Grammatical Range and AccuracyCriterion 3: Grammatical Range and Accuracy

Band 6 vs 7 vs 9:

Band	Range	Accuracy
Band 6	Mix of simple and complex, but limited flexibility	Frequent errors; meaning rarely obscured but error-free sentences are uncommon
Band 7	Variety of complex structures with flexibility	Frequent error-free sentences; occasional errors persist
Band 9	Full, natural, flexible range	Only rare non-systematic slips

The minimum toolkit for Band 7 — force each into Part 3 practice:

• Conditionals: "If cities invested in cycling lanes, commuting would..."
• Perfect tenses: "I've been living here since..." / "By 2030, AI will have changed..."
• Relative clauses: "..., which is why I think..."
• Contrast structures: "Although tourism brings money, it also..."
• Passive where natural: "The law was introduced to..."

Accuracy rule: Band 7 needs frequent error-free sentences. The highest-yield fixes are tense consistency (do not drift from past to present mid-story in Part 2) and articles. Record yourself for 2 minutes, transcribe one minute, and circle every error — most candidates find the same 3 errors repeating. Fix those three and accuracy jumps.

Part 3 is where range is proven — abstract questions force complex structures. Prepare with our Part 3 strategy guide.

Jump to Criterion 4: PronunciationCriterion 4: Pronunciation

Accent is irrelevant. The descriptor scores four features:

1. Individual sounds: /θ/ vs /s/, /v/ vs /w/ — the pairs that change meaning.
2. Word and sentence stress: "PHOtograph" vs "phoTOgraphy"; stressing the content words in a sentence.
3. Rhythm and chunking: grouping words into thought phrases with natural pauses, not word-by-word delivery.
4. Intonation: rising for yes/no questions and uncertainty, falling for statements and conclusions. Flat intonation caps you at 6.

Fastest wins (1-2 weeks):

• Sentence stress: stress nouns/verbs/adjectives, swallow grammar words. "I WENT to the MARket to BUY some FRUIT." This single change makes most Band 6 speakers instantly clearer.
• Chunking: pause at clause boundaries, not mid-phrase. Read a paragraph aloud marking / where you pause — pauses inside a noun phrase ("the big / red car") signal Band 6.
• Word stress in -tion/-sion/-graphy words: these follow strict rules and appear constantly in academic topics.

For a model to shadow, listen to the audio in our Band 9 cue card answers and mimic stress and chunking, not accent.

Each criterion gets a band; the average rounds to the nearest half band. 6.75 rounds up to 7.0; 6.25 rounds down to 6.0. One criterion at 6 is survivable (7/7/7/6 → 7.0). Two at 6 keeps you at 6.5 — which is why diagnosing the two weakest criteria matters. Compare with Writing descriptors, which work identically.

1. Record a Part 2 talk (2 minutes) and a Part 3 answer (1 minute).
2. Fluency: count silent pauses over 2 seconds. More than 3 per minute → Fluency is a leak.
3. Vocabulary: count repeated adjectives ("good," "nice," "big"). More than 5 → Lexical Resource.
4. Grammar: transcribe 60 seconds. Fewer than half the sentences error-free, or zero conditionals/complex sentences → Grammar.
5. Pronunciation: play it to a friend at 1x speed. Anything they ask you to repeat → Pronunciation clarity issue.

Fix in speed order: Fluency structure (days) → Grammar variety (weeks) → Vocabulary precision (weeks) → Pronunciation features (months). Then validate with AI-scored practice — Band9Prep's Speaking tool scores all four criteria per attempt.

Jump to Frequently Asked QuestionsFrequently Asked Questions

Does speaking fast give a higher score? No. Speed without coherence scores lower than moderate, well-linked speech. Examiners penalise rushed, mumbled delivery under Pronunciation.

Can I ask the examiner to repeat the question? Yes — "Could you rephrase that, please?" is natural and unpenalised once or twice. Staying silent or answering a different question costs far more.

Is Part 2 the most important part? No. All three parts feed all four criteria. But Part 2 is where Fluency differences show most clearly, since it is the longest continuous speech.
