How IELTS Speaking Examiners Mark Your Test: An Inside Guide

IELTS Speaking is the only section of the test where you interact with a human examiner in real time. This creates a unique dynamic: you are being assessed on your English ability while simultaneously trying to have a natural conversation. Understanding exactly how examiners mark your performance removes much of the mystery and allows you to focus your preparation on the specific criteria that determine your score.

This guide explains the four marking criteria examiners use, what they actually listen for in each criterion, common misconceptions that lead candidates astray, and practical strategies for each criterion. For a broader look at IELTS scoring, see our How IELTS Is Scored guide. For speaking tips, see our 20 Expert Speaking Tips.

The Four Marking Criteria

Every IELTS Speaking examiner marks your performance on exactly four criteria, each weighted equally at 25% of your Speaking score:

1. Fluency and Coherence (FC) — How smoothly and logically do you speak?

2. Lexical Resource (LR) — How wide and precise is your vocabulary?

3. Grammatical Range and Accuracy (GRA) — How varied and correct is your grammar?

4. Pronunciation (P) — How clearly and naturally do you pronounce English?

Your overall Speaking band score is the average of these four criteria, rounded to the nearest half or whole band. Understanding each criterion in detail tells you exactly what to practice.

Criterion 1: Fluency and Coherence

This criterion measures two related but distinct qualities:

Fluency

Fluency is about maintaining a natural, continuous flow of speech without unnatural pauses, repetition, or self-correction. Examiners assess:

• Can you speak at length without frequent pausing to search for words?
• Are your pauses in natural places (between ideas) rather than in the middle of phrases?
• Do you self-correct occasionally (acceptable) or constantly (reduces fluency)?
• Can you speak at a comfortable speed — neither rushed nor painfully slow?
• Do you use fillers naturally ('well,' 'you know,' 'let me think') or do you freeze in silence when thinking?

Coherence

Coherence is about the logical organization of your ideas:

• Do your answers make logical sense? Does each sentence connect to the next?
• Do you develop ideas with reasons and examples rather than giving one-word or one-sentence answers?
• Do you use discourse markers naturally ('so,' 'because,' 'for example,' 'on the other hand')?
• Can you signal topic shifts clearly when moving from one idea to another?

The most common mistake for fluency is speaking too slowly because you are trying to avoid errors. Examiners prefer natural speed with occasional errors over slow, overly careful speech. It is better to speak naturally and make a few mistakes than to pause every few words to think about grammar.

Criterion 2: Lexical Resource (Vocabulary)

This criterion assesses the range and precision of your vocabulary. Examiners listen for:

• Do you use topic-specific vocabulary? When discussing health, do you say 'sedentary lifestyle' and 'cardiovascular disease' rather than 'sitting too much' and 'heart problems'?
• Can you paraphrase when you cannot find the exact word? Instead of stopping, can you explain the concept in different words?
• Do you use idiomatic expressions naturally (not forced)? Using idioms well shows advanced vocabulary, but using them incorrectly or inappropriately can reduce your score
• Do you use collocations correctly? 'Make a decision' (correct) vs 'do a decision' (incorrect); 'heavy traffic' (correct) vs 'big traffic' (incorrect)
• Do you avoid repeating the same vocabulary throughout the test? If the topic is education, do you vary between 'students,' 'learners,' 'pupils,' 'young people'?
• Can you use less common vocabulary appropriately? Using 'ubiquitous' correctly demonstrates higher vocabulary than always saying 'very common'

Criterion 3: Grammatical Range and Accuracy

This criterion assesses both the variety of grammar structures you use and how accurately you use them:

Range (variety of structures)

• Do you use a mix of simple, compound, and complex sentences?
• Can you use a range of tenses naturally? (present, past, future, conditional, perfect tenses)
• Do you use relative clauses ('The company where I work...'), conditionals ('If I had more time, I would...'), and passive voice ('The decision was made by...')?
• Can you use reported speech, comparatives, and superlatives correctly?

Accuracy (correctness)

• Are your sentences mostly error-free?
• Do you make basic errors (subject-verb agreement, article usage) or only occasional slips with more complex structures?
• Do you self-correct when you notice errors? (This is seen positively if done naturally)
• Are your errors systematic (the same mistake repeatedly) or isolated (occasional slips)?

Important: Examiners assess range AND accuracy. Using only simple grammar accurately will not score Band 7+. Using complex grammar with many errors will also not score Band 7+. You need both variety and accuracy. For common grammar issues, see our Grammar Mistakes guide.

Criterion 4: Pronunciation

Pronunciation is the criterion most misunderstood by candidates. Examiners assess:

• Individual sounds: Can you distinguish between similar sounds (e.g., /l/ and /r/, /v/ and /w/, /θ/ (th) and /s/)?
• Word stress: Do you stress the correct syllable in multi-syllable words? ('deCISion' not 'DEcision'; 'photoGRAPHy' not 'PHOtography')
• Sentence stress: Do you emphasize content words (nouns, verbs, adjectives) more than function words (articles, prepositions)?
• Intonation: Does your voice rise and fall naturally, especially for questions, lists, and emphasis?
• Connected speech: Do you link words naturally in phrases ('turn_off' sounds like 'turnoff,' 'want_to' sounds like 'wanna')?
• Intelligibility: Can the examiner understand everything you say without effort?

You do NOT need a native English accent to score Band 9 in Pronunciation. IELTS does not penalize accents — whether Indian, Chinese, Arabic, Spanish, or any other. What matters is that your pronunciation is clear, your stress and intonation patterns are natural, and the examiner can understand you without difficulty.

Common Misconceptions About Speaking Marking

1. Myth: The examiner's friendliness indicates your score — Examiners are trained to be pleasant regardless of your performance. A friendly examiner does not mean you are scoring well, and a neutral examiner does not mean you are doing poorly

2. Myth: Long answers are always better — Quality matters more than length. A well-organized 30-second answer can score higher than a rambling 90-second answer. In Part 1, answers of 2-4 sentences are ideal. In Part 3, 4-6 sentences are usually sufficient

3. Myth: Using complex vocabulary always helps — Using advanced vocabulary incorrectly hurts your score more than using simple vocabulary correctly. Only use words and expressions you are confident about

4. Myth: The examiner marks you on your opinions — The examiner does not evaluate whether your opinions are 'right' or 'wrong.' They assess your English, not your ideas. You could argue that the Earth is flat and still score Band 9 if your English is excellent

5. Myth: Memorized answers score well — Examiners are trained to detect rehearsed responses. Memorized answers sound unnatural and are marked lower on Fluency and Coherence because they do not demonstrate spontaneous language ability

6. Myth: You need perfect grammar — Even Band 8 and 9 speakers make occasional grammar errors. What matters is that the majority of your sentences are accurate and that you use a range of complex structures naturally

What Happens After the Speaking Test

The examiner records the entire test. After the test, they review the recording and assign a band score for each of the four criteria. A second examiner or a senior examiner may review a random sample of recordings for quality assurance. Your Speaking score is combined with your Listening, Reading, and Writing scores to produce your overall IELTS band score.

Practical Tips for Higher Speaking Scores

1. Speak at a natural pace — neither too fast (which causes pronunciation errors) nor too slow (which hurts fluency)
2. Develop every answer with a reason, example, or personal experience — do not give one-sentence responses
3. Use topic-specific vocabulary when discussing common IELTS themes (environment, technology, education, health, culture)
4. Self-correct naturally when you notice an error — saying 'I have went — sorry, I have been to Japan' shows grammatical awareness
5. Practice speaking about a wide range of topics for 2 minutes (Part 2 preparation) — use the 1-minute preparation time effectively. See our
6. Part 2 Preparation Strategy
7. Record yourself and listen back — you will notice pronunciation habits, grammar patterns, and filler word usage that you cannot hear in real time

How do examiners handle nervous candidates?

Examiners are trained to put candidates at ease and to distinguish between nervousness and lack of English ability. A few seconds of hesitation at the start of a response, or a shaky voice, will not affect your score. What matters is whether you can produce coherent, developed answers once you begin speaking. If nervousness causes you to give very short answers or avoid complex language, that will affect your score — not because you are nervous, but because the examiner can only assess the language you actually produce during the test.

Key Takeaways

• Speaking is marked on four equally weighted criteria: Fluency/Coherence, Vocabulary, Grammar, and Pronunciation
• You do NOT need a native accent — clarity and natural stress/intonation patterns are what matter for pronunciation
• Quality of answers matters more than length — develop ideas with reasons and examples rather than speaking at length without substance
• Memorized answers are detected and penalized — practice spontaneous responses to a variety of topics instead
• The examiner assesses your English ability, not your opinions, knowledge, or personality — focus on demonstrating your language skills
