Mastering IELTS Writing: A Guide to Band Descriptors in 2025
Preparing for the IELTS Writing test can be intimidating, especially when your academic or career goals depend on achieving a high band score. Understanding how IELTS Writing is scored - specifically, the band descriptors - is the most effective way to target your preparation, maximize your performance, and avoid common mistakes. In this detailed guide, we'll break down the four core assessment criteria: Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range & Accuracy, explain what examiners look for in practice, and share actionable strategies, model examples, and tips to help you meet their expectations in 2025.
What Are IELTS Writing Band Descriptors?
Before we dive in, let's clarify: band descriptors are the official scoring guidelines used by examiners to rate your writing. These descriptors set out precisely what makes an essay or report a Band 9 (Expert User), Band 7 (Good User), and so on, down to Band 1. Each criterion accounts for 25% of your score in both Writing Task 1 (report or letter) and Task 2 (essay).
The Four Criteria Explained
- Task Achievement/Task Response
- Coherence and Cohesion
- Lexical Resource
- Grammatical Range & Accuracy
In 2025, these remain the pillars of marking for both IELTS Academic and General Training modules (source).
1. Task Response: The Heart of Your Score
What is Task Response?
For Task 2 (Essay), "Task Response" means fully answering ALL parts of the prompt with relevant, developed, and supported ideas.
For Task 1, this is called "Task Achievement." The underlying principle is the same: respond appropriately, include all key points, and avoid going off-topic.
Examiners look for:
- A clear, relevant response to every part of the prompt
- Well-developed main ideas, fully extended and supported
- Your personal position (when asked) that's evident throughout
- No underdeveloped, irrelevant, or missing content
What does this look like in practice?
Example Prompt (Task 2):
Some people think that parents should teach their children how to be good members of society. Others, however, believe that school is the best place to learn this. Discuss both views and give your own opinion.
Band 7-9 Model Features:
- Discuss both parental and school responsibilities with balanced arguments
- Offer your own opinion, clearly stated and maintained (e.g., "I believe both parents and schools must share this responsibility...")
- Develop each idea (don't just list) with explanations and examples
Band 5 Mistake:
- Only talks about schools with vague reasons - misses the 'parents' aspect, or fails to give own opinion.
Band Descriptor Table (Task 2: Task Response)
| Band | What it Means |
|---|---|
| 9 | Fully addresses all parts; ideas are relevant, fully developed, well-supported |
| 7 | Addresses all requirements; position is clear throughout; some ideas could be extended further |
| 6 | Addresses task generally; position may not always be clear; ideas may be unclear or insufficiently developed |
| 5 | Generally addresses the topic but may partially answer prompt or develop ideas inadequately |
How to Maximize Task Response:
- Always identify all parts of the prompt: Is it asking for opinion, causes and solutions, advantages/disadvantages?
- Plan before writing: Quickly note your main points for each part.
- Stay specific: Use concrete examples ("For instance, in Finland, parents..."), not vague claims.
- Restate your position in your conclusion to leave a strong final impression.
2. Coherence and Cohesion: How Well Your Writing Flows
What is Coherence and Cohesion?
- Coherence: Logical flow and clarity of your ideas, paragraphing, and essay structure.
- Cohesion: Use of linking words (more than just "Firstly"...), reference, and substitution to connect ideas and avoid repetition.
Examiners look for:
- Clear organization (introduction, body, conclusion)
- Logical sequence of ideas
- Paragraphs with a single focus, well-developed
- Cohesive devices (linkers, referencing) used naturally, not overused
Practical Examples:
Band 7-9 Features:
- Each paragraph has a topic sentence and logically builds the argument.
- Connectors used correctly: "Furthermore", "On the other hand", "For example", "This means that..."
- Reference words for cohesion: "these measures", "such policies", replacing nouns with pronouns when safe.
Common Mistake:
- Overusing basic connectors ("Moreover, Moreover, Moreover...").
- No clear paragraphs - just one long block of text.
Band Descriptor Table (Coherence and Cohesion)
| Band | Features |
|---|---|
| 9 | Message can be followed effortlessly; paragraphing and cohesion are natural, sophisticated |
| 7 | Logically organized; clear progression; flexible use of references and linkers, occasional inaccuracies |
| 5-6 | Somewhat logically organized, but connections and paragraph structure may be mechanical or faulty |
How to Boost Coherence and Cohesion:
- Draft essay outlines to assign points/ideas to each paragraph.
- Vary your linking phrases - don't start every sentence with "Firstly".
- Practice substitution and referencing (replacing nouns with "this", "they", etc.).
- Use "PEEL" structure: Point, Example, Explanation, Link.
3. Lexical Resource: Your Vocabulary Arsenal
What is Lexical Resource?
- The range, accuracy, and appropriateness of your vocabulary.
- Ability to use less common words, paraphrase, and collocate phrases properly.
- Spelling and word formation accuracy.
Examiners look for:
- A wide range of topic-appropriate vocabulary
- Effortless paraphrasing (not just repeating the prompt's words)
- Few errors in word choice, spelling, or word forms
Practical Examples:
Band 8-9 Feature:
- Uses words like "vital", "societal norms", "influence", "nurture", "institutional responsibility" when discussing education or society
- Shows understanding of collocation: "government intervention", "academic performance", "parental involvement"
Band 5 Mistake:
- Repeats "good members of society" without synonyms
- Writes "do good things" instead of "contribute positively", or "basic morals"
Band Descriptor Table (Lexical Resource)
| Band | Features |
|---|---|
| 9 | Wide range of vocabulary; precise, sophisticated use; rare errors |
| 7 | Sufficient flexibility; some less common or idiomatic items; minor inaccuracies |
| 6 | Adequate but somewhat limited vocabulary; errors don't impede clarity |
| 5 | Limited resource; repetition; frequent misuse or errors |
How to Expand Your Lexical Resource:
- Read model essays and build a word bank for each IELTS topic (e.g., Environment, Education, Technology).
- Practice paraphrasing: Find new ways to say "advantage", "problem", "increase", "important".
- Learn collocations: e.g., "raise awareness", "pose a threat", "implement measures", not just "do" or "make".
- Self-check for word form and spelling errors.
- Avoid memorized phrases, clichés, or overly obscure words. Aim for natural variety.
4. Grammatical Range and Accuracy: Your Sentence Power
What is Grammatical Range and Accuracy?
- Your ability to use a mix of simple and complex sentences, accurately and appropriately.
- Good control of tense, agreement, articles, punctuation, and word order.
Examiners look for:
- Variety - do you use both simple and complex structures (like conditional sentences, relative clauses)?
- Frequent error-free sentences
- Punctuation accuracy
Practical Examples:
Band 8-9 Feature:
- Uses complex structures with minimal mistakes:
- "Although parents may influence their children more than anyone else, school also plays an important role in developing social skills."
- "If educational institutions are required to include moral education, children will be more likely to become responsible adults."
Band 5 Mistake:
- Only short/simple sentences: "Parents are important. Schools are important. Both help children."
- Frequent mistakes in verb tense or agreement: "Schools gives children skill. Parents give advices."
Band Descriptor Table (Grammatical Range & Accuracy)
| Band | Features |
|---|---|
| 9 | Wide range, full flexibility, rare minor errors |
| 7 | Variety of complex structures, generally well-controlled |
| 6 | Mix of simple and complex forms, limited flexibility, some errors |
| 5 | Limited range, many errors, mainly simple sentences |
How to Improve Grammatical Range & Accuracy:
- Learn "sentence starters" for conditionals, concessions, and cause-effect: "Although...", "Even if...", "As a result..."
- Master relative clauses: "who", "which", "that"
- Watch for articles (a, an, the) and subject-verb agreement
- Punctuate complex sentences: commas after dependent clauses
- Get feedback - use tools like Essay Tutor to identify grammar mistakes you overlook
How are IELTS Writing Scores Calculated in 2025?
- Each criterion above counts as 25% of your Task 1 and Task 2 marks.
- Writing Task 2 is worth twice as much as Task 1 in your final band (source: IELTS.org).
- Example: If you score 8 for Task 1 and 7 for Task 2, your Writing score would not be the average but weighted more towards Task 2.
- Your overall Writing band is rounded according to IELTS band calculation rules.
What Do the IELTS Writing Bands Mean?
| Overall Band | What It Means ("Skill Level") |
|---|---|
| 9 | "Expert" - Fully operational command, completely natural, error-free usage |
| 8 | "Very good" - Occasional mistakes, handles complex arguments well |
| 7 | "Good" - Operational command, some inaccuracies, manages complex language |
| 6 | "Competent" - Effective command, fairly accurate, some misunderstandings |
| 5 | "Modest" - Partial command, can communicate basic ideas with many mistakes |
Band 7 or higher is typically required for university admission or skilled migration in most English-speaking countries.
Common IELTS Writing Mistakes and How to Avoid Them
1. Missing Parts of the Question
- Solution: Carefully dissect the prompt; underline each task.
2. Off-topic, Memorized, or Template Responses
- Solution: Always tailor your answer. Examiners spot memorized phrases easily.
3. Poor Paragraphing
- Solution: Use a clear introduction, separate body paragraphs for each point, and a conclusion.
4. Overusing Basic Linkers
- Solution: Use a variety- "nevertheless", "consequently", "for instance", "in addition".
5. Repetitive or Basic Vocabulary
- Solution: Paraphrase. Use topic-specific vocabulary and collocations.
6. Short, Simple Sentences Only
- Solution: Vary your sentence structures; combine ideas with complex sentences.
7. Ignoring Word Count or Time Management
- Solution: Write at least 250 words for Task 2, finish drafts in 40 minutes.
Real-World IELTS Band 7+ Essay Example (with Analysis)
Prompt:
Some people think that the teenage years are the happiest time of most people's lives. Others think that adult life brings more happiness, in spite of greater responsibility. Discuss both views and give your own opinion.
Model Paragraph:
Many argue that adolescence is the happiest phase of life because young people are relatively free from major responsibilities and pressures. Teenagers typically benefit from strong family support, enjoy ample leisure time, and are able to form deep friendships. For example, most high school students report that school breaks and time spent socializing with friends are their most memorable experiences. However, others believe that adulthood brings greater life satisfaction. Adults have the freedom to make important decisions, pursue meaningful goals, and build families of their own, which can foster a lasting sense of accomplishment. In my view, while both stages offer unique joys, personal fulfillment often peaks during adulthood as individuals see their ambitions realized and form strong emotional bonds.
Why this meets Band 7+ descriptors:
- Task Response: Fully addresses the two viewpoints and gives a clear, well-supported opinion.
- Coherence & Cohesion: Paragraphs are logical, linking phrases like "however", "for example", "in my view".
- Lexical Resource: Vocabulary is precise and topic-specific ("adolescence", "major responsibilities", "life satisfaction", "personal fulfillment").
- Grammatical Range & Accuracy: Uses complex sentences, relative clauses, and a variety of structures accurately.
Band Descriptor Myths and Updates for 2025
Has Anything Changed Recently?
IELTS and the organizations behind it (British Council, IDP, Cambridge) regularly review and update assessment descriptors to ensure fairness and consistency (latest update). In 2025, the focus remains on:
- Transparency: Descriptors are publicly available.
- Frequent examiner training.
- Double-marking for fairness.
Myth-busting:
- "Only native speakers get Band 9." Not true-non-natives who demonstrate complete command, awareness of style and register, and natural-sounding writing can achieve top marks.
- "Memorizing high-level vocabulary guarantees a high band." Not if it's used incorrectly, or makes your answer unnatural.
- "You must have zero errors to get Band 8+." Occasional minor errors are allowed as long as they do not affect communication.
