Here’s something I used to see over and over with my students. They walk into the speaking test, they perform, trying to sound impressive, trying to sound fluent, trying to sound like a native speaker, and in doing so, they completely miss what the examiner is actually sitting there listening for.
IELTS is a British exam. It’s managed by Cambridge and the British Council, and it follows very specific, very logical patterns. Once you understand those patterns, once you see the map, the whole thing changes.
So here is that map. There are exactly four criteria your examiner is marking you on. Each one is worth 25% of your score. Each one rewards very specific things. And each one is completely learnable once you know what to look for.
1. Fluency & Coherence: The Flow Factor
The biggest mistake students make here is thinking fluency means speed. It doesn’t. What examiners are actually listening for, and this is straight from the examiner’s handbook, is something called undue hesitation.
There’s an important distinction most students never hear about. Hesitating because you’ve lost your train of thought lowers your score. But hesitating because you’re genuinely considering something complex? That’s natural, and a good examiner knows the difference.
The problem is the sound you make while you hesitate. “Uh... um... uh...” signals to the examiner that your language has stalled.
The fix is to replace those sounds with fillers: Phrases like “Let me see...”, “That’s a tricky one...”, or “How can I put this...” buy you the same amount of thinking time - but they sound considered rather than lost. That’s a small change with a significant impact.

Coherence is the second half of this criterion. Use linking words to make your logic easy to follow: “However,” “Consequently,” “What I mean by that is...” These act as signposts, showing the examiner that your ideas are connected and moving forward. Words like “Nevertheless,” “As a result,” and “Having said that” signal a more sophisticated speaker. The key is to practise them out loud so they feel natural when it counts.
Practice tip: Answer questions out loud every single day - not just in your head. Record yourself, and when you hesitate, train yourself to reach for a filler.
2. Lexical Resource: Precision Over Complexity
There’s a trap in this criterion. When students hear “lexical resource,” they think it means: use impressive, complicated vocabulary. So they learn a list of advanced words and drop them into answers regardless of whether they quite fit. This is worse than using a simple word correctly.
What examiners are actually looking for is idiomatic language and topic-specific vocabulary used naturally. It’s not the size of the word - it’s whether you’re using it the way a real speaker would. Collocation errors are a red flag: “do a decision” instead of “make a decision,” “strong rain” instead of “heavy rain.”
Learn vocabulary in phrases, not in isolation. Don’t just learn the word “decision” - learn “make a decision,” “reach a decision,” “a difficult decision.”
If you forget a word mid-test, your instinct is to go silent and desperately try to remember it. Don’t. That pause is what costs you marks, not the forgotten word itself. Instead, describe it. Keep talking and work around it. If you can’t remember “commute,” say “the journey I make every day to get to work.”
If you can’t remember “procrastinate,” say “when you keep putting something off even though you know you should do it.”
This is called lexical flexibility, and it’s exactly what examiners are trained to reward at band 7 and above.

Think of your vocabulary like a city. A band 5 speaker knows one road - if it’s blocked, they’re stuck. A band 7 speaker knows three different routes. Lexical flexibility is just knowing your way around.
3. Grammatical Range & Accuracy: The Range Trap
You can speak in perfect, flawless, 100% accurate simple sentences for the entire test - and you will not get above a band 6. Because the clue is in the name: it’s not just accuracy. It’s range. Your examiner needs to hear a variety of structures to award a 7 or above.
A simple framework to build this in is the Grammar Triple Threat. In every part of the speaking test, aim to use at least one of each:
- Conditional: “If I had the opportunity, I would...”
- Relative clause: “...which is something I find really interesting because...”
- Present perfect: “I’ve been living there for about three years now.”
These three structures alone demonstrate the kind of grammatical range that pushes scores up. Build them into your preparation so deliberately that they feel automatic on the day.
4. Pronunciation: The Music of English
Let’s be very clear about something, because this causes unnecessary anxiety. Your accent does not matter. IELTS examiners are explicitly trained not to penalise regional or national accents - as long as your speech can be understood. What they are listening for is something different entirely: intonation.
English has a kind of music to it. We stress certain words, usually the nouns and verbs, the content words, and we group ideas together in chunks, with natural pauses between them. When students are nervous, they tend to flatten everything out into one long, even stream. It becomes genuinely difficult to follow.
Practise stressing your key words and pausing between ideas - not to sound more native, but because it makes you easier to listen to.
The best tool for training this is called shadowing. Listen to a native speaker and repeat what they say almost simultaneously, mimicking not just the words but the rhythm, the stress, and the pauses. It rewires the way your mouth and brain work together in English, and it’s one of the most effective pronunciation techniques available.
The full map
Four criteria. Each worth exactly 25%. Each completely learnable once you know what you’re being marked on:
- Fluency & Coherence
- Lexical Resource
- Grammatical Range & Accuracy
- Pronunciation
The students who transform their scores aren’t always the ones who studied the hardest. They’re the ones who understood how to play the game.
