Understanding the four band descriptors and common mistakes to avoid

The IELTS Writing test challenges many test-takers, but knowing what the examiners want can make all the difference. Your writing is assessed based on four critical band descriptors: Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
Let’s simplify these terms and highlight what to avoid in your writing.
1. Task Achievement (Task 1) / Task Response (Task 2)
What it Means
This measures how well you fulfill the requirements of the task. For Task 1, it’s about presenting a clear overview and accurate information. For Task 2, it involves answering the question fully and developing your ideas.
Things to Avoid
- Straying off topic: Always stick closely to what the task asks you to do.
- Ignoring parts of the task: Make sure to address every part of the question.
- Writing too generally: Provide specific examples and detailed explanations.
- Failing to reach the word count: Write at least 150 words for Task 1 and 250 for Task 2.
- Over-generalizing your answer: Use data or specific details, especially in Task 1, to support your points.
2. Coherence and Cohesion
What it Means
This is about how well your writing flows and how your ideas are organized. Linking words and clear paragraphing are essential here.
Things to Avoid
- Jumping from one idea to another: Organize your writing so that it logically flows from one point to the next.
- Overusing linking words: While important, too many can make your writing hard to follow.
- Having unclear paragraphing: Start a new paragraph for each main idea.
- Lack of or incorrect use of referencing words (e.g., ‘this,’ ‘these,’ ‘it’): Use them correctly to avoid confusion.
- Writing without a clear introduction or conclusion: Both are crucial for setting up and summarizing your main points.
3. Lexical Resource
What it Means
This refers to your use of vocabulary. A wide range of vocabulary used appropriately can impress the examiner.
Things to Avoid
- Repeating words too often: Try to use synonyms where possible.
- Using words incorrectly: Make sure you know the exact meaning of a word before you use it.
- Relying on simple vocabulary: Challenge yourself to use higher-level words.
- Inappropriate use of informal language: Stick to a formal or semi-formal style.
- Spelling errors: Incorrect spelling can detract from your lexical resource score.
4. Grammatical Range and Accuracy
What It Means
Your ability to use a variety of grammatical structures accurately is key. A mix of simple and complex sentences shows your skill level.
Things to Avoid
- Using only simple sentences: Incorporate complex grammatical structures.
- Making frequent grammatical errors: While perfection isn’t expected, too many mistakes will lower your score.
- Incorrect verb tense usage: Ensure you’re using the correct tense for your context.
- Ignoring sentence punctuation: Correct use of commas, periods, and other punctuation marks is crucial.
- Over-complicating sentences: Sometimes, trying too hard to use complex structures leads to errors. Aim for a balance.
By understanding these descriptors and knowing what to avoid, you can better prepare for the IELTS Writing test. Practice consistently, review your work for errors, and try to incorporate a range of vocabulary and grammatical structures into your writing.
