Unlocking the 4 IELTS Speaking assessment criteria
Unlock the 4 IELTS Speaking assessment criteria to practice smarter, identify weaknesses, and target a higher band score.
Here is a detailed breakdown of each criterion and how you can optimize your performance:
1. Fluency and Coherence
This criterion assesses your ability to speak continuously, naturally, and connect your ideas logically. This is often the criterion that test-takers find most challenging.
| Key factor | How to optimize |
|---|---|
| Speaking speed | Maintain a steady pace - not too fast or too slow. Avoid prolonged hesitations or long silences. |
| Answer length | Provide full answers, specifically in Part 2, you must speak for the full two minutes. |
| Coherence | Use discourse markers (linking words, discourse signals) and transition signals (such as However, Therefore, On the other hand, Speaking of...) to connect sentences and ideas. |
| Self-correction | Naturally correcting your own mistakes is acceptable and even shows control over your language. |
2. Lexical Resource
This criterion assesses the variety, accuracy, and flexibility of the vocabulary you use.
| Key factor | How to optimize |
|---|---|
| Variety | Use a wide range of vocabulary and phrases. Avoid repeating a key word too often (use synonyms). |
| Less common vocabulary | Use less common vocabulary, especially collocations (commit a crime, heavy rain, launch a campaign…) and idioms. |
| Accuracy | Ensure vocabulary is used in the correct context and form (noun, verb, adjective). |
| Paraphrasing | The ability to rephrase the question or someone else's idea using your own words. |
3. Grammatical Range and Accuracy
This criterion assesses your ability to use a variety of grammatical structures (Range) and to do so without making errors (Accuracy).
| Key factor | How to optimize |
|---|---|
| Range | Flexibly use both simple, compound, and complex sentences. |
| Structural variety | Use complex structures such as the perfect tenses (Present Perfect), conditional sentences, relative clauses, and the passive voice when appropriate. |
| Accuracy | Minimize basic errors such as verb conjugation errors, singular/plural agreement, and preposition errors. |
4. Pronunciation
This criterion assesses how easily the examiner can understand your speech and how you use the suprasegmental features of English.
| Key factor | How to optimize |
|---|---|
| Intelligibility | Your speech must be easily understood by the examiner without undue effort. |
| Word stress | Place emphasis on the correct syllable within a word (de-VEL-op rather than DE-vel-op). |
| Sentence stress | Emphasize the most important information-carrying words in a sentence. |
| Intonation | Use natural intonation, raising/lowering your voice appropriately to convey meaning and emotion (distinguishing between questions and statements…). |
| Accent | Note: You are not required to speak with a particular accent. Your local accent is acceptable, provided your pronunciation is clear and easy to understand. |
