Every IELTS speaking test is scored on exactly 4 criteria, each worth 25% of your band score. Yet most candidates spend 80% of their prep time on just two of them. Understanding all four — and where you stand on each — is the foundation of a smart study plan.
4 criteria. Each worth 25%. Most candidates only train 2.
The IELTS speaking rubric is publicly available — yet most test-takers have never read it. They study vocabulary and grammar intensively, then treat pronunciation and fluency as afterthoughts. The score reflects exactly that imbalance.
What each criterion actually measures
Fluency & Coherence
Ability to speak at length without long pauses or self-correction. Ideas should connect logically — not just strung together with "and, and, and."
Lexical Resource
Range and precision of vocabulary. Knowing when to use "happy" vs "elated" vs "content" vs "satisfied" — the right word in the right context.
Grammatical Range & Accuracy
Attempting and correctly using complex structures — conditionals, passives, relative clauses. Not just simple present and past tense.
Pronunciation
Can the listener follow you easily without strain? This is not about accent — a strong accent with clear articulation scores well. Mumbling with a "neutral" accent does not.
A low score in one criterion drags down your entire band
Because the four scores are averaged, Band 7 in vocabulary and grammar but Band 5 in pronunciation and fluency still gives you Band 6 overall. Your ceiling is set by your weakest criterion — not your strongest.
Tomorrow we'll look at one of the most common reasons candidates freeze in Part 2 — and what's actually happening when your mind goes blank under exam pressure.
