Fluency, Lexical Resource, Grammatical Range, Pronunciation — what each one actually checks
Every IELTS Speaking answer is scored on the same 4 real criteria, each on the real 0–9 band scale. Here’s exactly what each one checks for.
Fluency & Coherence
Answers immediately and naturally, for as long as the question genuinely calls for. Where the answer is long enough to need them, ideas connect naturally — not mechanically. Hesitation should read as natural thinking, not a struggle to find words. Brevity is never itself a flaw — a real Band 9 Part 1 answer is often just 2 to 4 natural sentences.
Lexical Resource
Vocabulary used naturally and precisely for what’s being expressed, with at least some less-common or topic-specific words used accurately — no mistranslated or overly generic choices where more precise language was called for, and no awkward repetition when the answer had room for variety.
Grammatical Range & Accuracy
A genuine range of structures — relative clauses, comparatives, conditionals, varied clause combinations — appropriate to what the answer needed to say, with no real errors and no repeated error pattern. Natural, correct structures score as highly as more complex ones, if they’re the right fit for what’s being said.
Pronunciation
Scored on its own — how clearly and naturally you’re understood, isolated from grammar, vocabulary, and how developed your answer is. A response can have real grammar mistakes and simple vocabulary while still being clearly and naturally spoken, and Pronunciation is scored on that basis alone.
