How IELTS Speaking Is Scored: The 4 Criteria

What the IELTS Speaking test is

IELTS Speaking is a face-to-face interview lasting 11–14 minutes, in three parts. Part 1 (4–5 minutes) is a two-way question-and-answer interview about familiar topics — home, work, studies, interests. It is a conversation, not a monologue. Part 2 is the long turn: you receive a cue card, get 1 minute to prepare notes on paper, then speak on your own for up to 2 minutes. Part 3 (4–5 minutes) is a two-way discussion of more abstract questions connected to your Part 2 topic.

One thing candidates often miss: there are no separate scores for each part. The examiner assesses your entire performance against the same four criteria, from the first Part 1 answer to the last Part 3 exchange.

The four IELTS Speaking criteria, equally weighted

The four assessment criteria come from the public Cambridge band descriptors, and none of them outweighs another. A brilliant vocabulary cannot rescue constant hesitation, and flawless grammar cannot rescue speech nobody can follow.

How your band score is calculated

For each criterion the examiner awards a whole band from 0 to 9. Your Speaking score is the average of the four, reported to the nearest half band — and averages that land on .25 or .75 are rounded up.

A worked example: Fluency and Coherence 7, Lexical Resource 6, Grammatical Range and Accuracy 6, Pronunciation 7. The average is (7 + 6 + 6 + 7) ÷ 4 = 6.5, so the Speaking band is 6.5.

Because the weighting is strictly equal, your fastest route to a higher band is usually your weakest criterion, not your strongest one. Raising Pronunciation from 6 to 7 moves your average exactly as much as raising Lexical Resource from 7 to 8 — and it is usually far easier.

What examiners actually listen for

The descriptors are written in exam language, but the signals behind them are concrete:

• Fluency and Coherence: whether you can keep going at length without visible effort, and whether your answer has a thread the examiner can follow.
• Lexical Resource: how you handle a missing word — paraphrase and carry on, or stall. Flexibility under pressure is the signal.
• Grammatical Range and Accuracy: whether you attempt complex structures at all, and whether errors are one-off slips or the same mistake repeating.
• Pronunciation: whether a stranger could follow you effortlessly — not whether you sound like a native speaker.

Examiners are also trained to recognise memorised answers — recited speech has a different rhythm from spontaneous speech, and it is reflected in the Fluency and Coherence score. Preparing ideas for common topics is smart; reciting scripts is not.

Why an honest score matters

A lot of practice tools — human and AI — quietly inflate scores, because a flattering band feels good and keeps you practising. The problem is that the real test doesn't flatter. If your practice scores run a band above your actual level, you find out on test day, with a visa deadline or a university offer attached to the result and a retake fee to pay.

An honest estimate — even when it stings — lets you plan: how many weeks of preparation you actually need, which criterion is holding you back, and whether you are ready to book. That is why we calibrate our scoring against the public Cambridge band descriptors and check it against reference sessions — the full process is described on our methodology page.

How to practise realistically

Since the score is built from the four criteria across the full 11–14-minute format, realistic practice means rehearsing that format — not just answering random questions. Practise the Part 2 long turn against a real timer with paper notes. And because Parts 1 and 3 are two-way, you need an interlocutor who asks unpredictable follow-up questions; that is the one part of the test you cannot fully rehearse alone.

IELTS Examiner AI runs the full three-part mock with an AI examiner — we are upfront that it is an AI — using the real exam format and timing, and returns an honest band with per-criterion feedback, so you always know which of the four criteria to work on next.
