How is the IELTS Speaking Test Scored?
IELTS Speaking is often misunderstood. Candidates walk out feeling fluent, confident, and expressive—only to receive a score lower than expected. This usually happens because IELTS Speaking is not scored on how confident you sound, but on how consistently your language matches four precise criteria.
The Speaking test is assessed across four equally weighted areas:
- Fluency and Coherence
- Lexical Resource
- Grammatical Range and Accuracy
- Pronunciation
Your final Speaking band is the average of these four scores, not a best-case result.
This means a candidate can perform very well in two areas, struggle in one, and still receive an overall lower score. This pattern is known as a jagged profile, and it is one of the most common reasons strong speakers fail to reach Band 7.
1. Fluency and Coherence: More Than “Speaking a Lot”
Fluency is not about speed or confidence. It refers to your ability to sustain speech naturally without visible effort, while keeping ideas logically connected.
At Band 6, candidates can usually keep talking, but coherence may be lost due to:
- Mid-sentence hesitation
- Repetition of words or ideas
- Self-correction that interrupts flow
These issues often appear while searching for language, not while thinking of ideas.
At Band 7, hesitation is still allowed—but with an important difference:
Hesitation may occur, often mid-sentence, but it does not affect coherence.
In practice, this means:
- You may pause briefly, but your listener never feels lost
- Your sentences still follow a clear logical sequence
- Ideas move from point A to point B without confusion
A key red flag examiners listen for is mid-sentence breakdown, where a candidate starts a sentence confidently but struggles to complete it smoothly. This signals difficulty accessing appropriate language, not a lack of ideas.
2. Lexical Resource: Range Is Not Enough
Many Band-6.5 speakers believe vocabulary is their strength—and often, they are right. They can discuss a wide range of topics, paraphrase effectively, and avoid repetition.
However, Band 7 requires flexible and appropriate use, not just range.
Examiners assess:
- Precision of word choice
- Awareness of style and collocation
- Ability to paraphrase naturally under pressure
A common issue is choosing a word that is close, but not quite right. Even if meaning remains clear, repeated inappropriacies signal that vocabulary control is not yet stable at Band 7 level.
Importantly, vocabulary issues often trigger fluency problems, because uncertainty about word choice leads to hesitation or reformulation.
3. Grammatical Range and Accuracy: The Role of Systematic Errors
Grammar is where many strong speakers quietly lose marks.
Band 7 does not require perfect grammar. It requires:
- A range of structures used flexibly
- Frequent error-free sentences
- Acceptance that a few basic errors may persist
The difference between Band 6 and Band 7 is the type of errors, not the number.
Band-6 candidates often make systematic errors—errors that repeat consistently, such as:
- Article misuse (a / the / no article)
- Subject-verb agreement
- Plural marking
These errors signal that the rule has not been fully internalised.
At Band 7, errors still occur, but they are:
- Less predictable
- Less frequent
- Less disruptive to clarity
If an examiner notices the same grammatical mistake appearing again and again, this strongly limits the score, even if the speaker is otherwise fluent.
4. Pronunciation: Intelligible Is Not the Same as Effective
Pronunciation is not about accent. Accents are fully acceptable as long as they do not reduce understanding.
Band-6 pronunciation is typically clear but flat:
- Speech is understandable
- Chunking is mostly appropriate
- Intonation and stress are inconsistent
Band-7 pronunciation shows control, not perfection:
- Sentences are broken into meaningful chunks
- Stress highlights important words
- Intonation rises and falls naturally across longer answers
A common Band-6 issue is run-on delivery—long sentences spoken on a single rhythm with minimal stress variation. This makes listening effortful, even when every word is clear.
Effective use of pauses, stress, and pitch gives the listener “mental breathing room” and strengthens coherence.
Why Confident Speakers Still Get Band 6
Many candidates feel fluent because they can speak at length, especially on familiar topics. However, IELTS Speaking rewards consistency, not moments of strength.
A typical Band-6 profile looks like this:
- Fluency: 6
- Vocabulary: 7
- Grammar: 6
- Pronunciation: 6
The result is an overall Band 6, even though the speaker clearly has advanced ability.
This is why preparation for Band 7 is not about “speaking more” or “learning harder vocabulary”, but about reducing friction:
- Fewer mid-sentence breakdowns
- Fewer repeated grammar errors
- Better control of stress and intonation
The Key Insight
IELTS Speaking is not a conversation test. It is a performance measured against descriptors.
Examiners are trained to listen for:
- How easily language is accessed
- How predictable your errors are
- How much effort the listener needs to follow you
Once candidates understand this, their preparation becomes more focused—and Band 7 becomes realistic rather than mysterious.
If you’re stuck at Band 6 or 6.5 in Speaking and can’t see why, the problem is usually not vocabulary or confidence—it’s how your performance aligns with the band descriptors.
