The IELTS speaking test: what it actually measures

The IELTS speaking test is a face-to-face interview of 11 to 14 minutes with a certified examiner. It is the shortest section and the one candidates most often misunderstand, because it looks like a conversation and is scored like a test.

The three parts

Part 1 — introduction and familiar topics (4–5 min). Your home, work, studies, hobbies. Short questions, short answers. Deliberately easy: it is there to settle you and to sample your baseline.

Part 2 — the long turn (3–4 min). You get a card with a topic, one minute to prepare with paper, then you speak alone for one to two minutes. This is the part everyone fears and the part that is most improvable, because its format never changes.

Part 3 — discussion (4–5 min). Abstract questions connected to Part 2's topic. Why do people…? What should governments…? This is where Band 7 and above is actually decided.

The four criteria — each worth 25%

1. Fluency and coherence — can you keep going, and do your ideas connect?
2. Lexical resource — range of vocabulary, and precision in using it.
3. Grammatical range and accuracy — variety of structures, not just correctness.
4. Pronunciation — intelligibility, stress and rhythm. Not accent.

Two of these routinely surprise people. Grammatical range means you are marked down for using only simple sentences even if every one is correct — accuracy alone caps you around Band 6. And pronunciation is not about sounding British; a strong Malayalam accent that is easy to follow scores well, while flat, evenly-stressed English scores poorly even when every sound is right.

Where marks are actually lost

Memorised answers. Examiners are trained to detect them, and they are penalised. A rehearsed paragraph delivered fluently scores lower than a hesitant genuine one.

Silence in Part 2. Running out at 40 seconds hurts more than making mistakes for two minutes. Fluency is 25% of your score, and it is measured by whether you keep going.

One-word answers in Part 1. Do you like your job? — Yes. You have given the examiner nothing to assess. Two or three sentences, always.

Not answering Part 3 abstractly. Part 3 asks about people in general, not about you. Answering In my family we… when asked Why do families… misses the register the band descriptors reward.

A preparation plan that works

• Part 1: Write out 15 common topics and speak for 30 seconds on each. Familiarity removes hesitation.
• Part 2: Practise the one-minute preparation, not just the speaking. Learn to write four bullet points, not sentences. Then always talk for the full two minutes — set a timer and do not stop early.
• Part 3: Practise the phrases for opinions and speculation: It depends on…, I'd say generally…, One reason might be…. These carry the register the examiner is listening for.
• All parts: Record yourself and listen once for fluency only, then once for range.

You cannot assess your own band. A mock test with someone who knows the descriptors is worth more than a month of solo practice — book a session, or see the IELTS preparation courses. For what band you actually need, read IELTS band scores explained.
