Understanding the IELTS Writing Scoring Criteria (Band Descriptors)
To score well in the IELTS Writing test, you need to know precisely how your Task 1 and Task 2 responses are evaluated. Examiners use detailed public IELTS Writing band descriptors based on four specific IELTS Writing criteria. Understanding these criteria helps you focus your practice effectively.
This guide breaks down the four key areas used for IELTS Writing scoring: Task Achievement (Task 1) / Task Response (Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
The Four IELTS Writing Criteria Explained
Both Task 1 and Task 2 are assessed using these criteria, each contributing 25% to the task score (though Task 2 has a greater weight on your overall Writing band).
- Task Achievement (TA) –
- What it means: How well you understood and fulfilled the requirements of the Task 1 prompt.
- To score well:
- Fully address all parts of the prompt (cover all bullet points for General Training, describe all key features for Academic).
- Present accurate information (select relevant data from the visual for Academic).
- Include a clear overview summarizing the main trends or features (Academic).
- Meet the minimum word count (150 words).
- Use the appropriate tone (General Training letters).
- Task Response (TR) – For Task 2 Only
- What it means: How well you addressed the essay question, developed your position, and supported your ideas.
- To score well:
- Fully address all parts of the question.
- Develop a relevant position with well-supported main ideas.
- Present clear and relevant arguments and examples.
- Avoid tangents or irrelevant information.
- Meet the minimum word count (250 words).
- Coherence and Cohesion (CC)
- What it means (for both tasks): How well organized and logically structured your writing is. How smoothly ideas are linked together between and within paragraphs.
- To score well:
- Organize information logically and clearly.
- Use paragraphs effectively (each with a central topic).
- Use a range of cohesive devices (linking words like “however,” “furthermore,” pronouns, substitution) appropriately and accurately, without over/under-use.
- Ensure your writing is easy to follow.
- Lexical Resource (LR)
- What it means (for both tasks): The range, accuracy, and appropriateness of the vocabulary you use.
- To score well:
- Use a wide range of vocabulary relevant to the topic.
- Use words accurately (meaning and form).
- Use less common lexical items naturally.
- Use collocations (natural word pairings) effectively.
- Have minimal errors in spelling and word formation; errors should not impede understanding.
- Grammatical Range and Accuracy (GRA)
- What it means (for both tasks): The variety and accuracy of the grammatical structures you use.
- To score well:
- Use a mix of simple and complex sentence structures.
- Produce frequent error-free sentences.
- Have good control over grammar and punctuation; errors should be rare and not impede communication.
Key Differences in Criteria Application
- Task 1 vs. Task 2 Weighting: Remember Task 2 contributes more to your final Writing score.
- TA vs. TR: The first criterion focuses on fulfilling the specific task type (describing data/writing a letter vs. developing an argument).
