IELTS Writing Band Descriptors: What Examiners Look For
IELTS Writing Band Descriptors (2026 Guide): What Examiners Really Want
Alright, IELTS writers—let’s open the “black box” that decides your score: IELTS Writing band descriptors.
Most students have seen the descriptors, but far fewer truly use them. And that’s the difference between “I practise a lot” and “I improve fast”.
Here’s the truth: examiners are not marking your writing based on vibes. They use four criteria, each worth 25% of your score. If you learn how these criteria work—and build them into your writing habits—you can improve your band score in a predictable way.
If you’re using IELTS Tutor, this post will also show you exactly how to practise smarter using structured feedback and targeted drills.
What Are IELTS Writing Band Descriptors?
Band descriptors are the official marking criteria used to assess:
- •
Academic Writing Task 1
- •
General Training Writing Task 1
- •
Writing Task 2 (both Academic + General Training)
They tell you what “Band 6” looks like, what “Band 7” requires, and what separates “Band 7” from “Band 8+”.
The Four Pillars of IELTS Writing (Each Worth 25%)
The IELTS Writing test is assessed using four equally weighted criteria:
- •
Task Achievement (Task 1) / Task Response (Task 2) Did you do what the task asked—fully and accurately?
- •
Coherence and Cohesion Is your writing easy to follow? Do ideas connect logically?
- •
Lexical Resource How strong and accurate is your vocabulary?
- •
Grammatical Range and Accuracy How varied and accurate is your grammar and sentence structure?
Neglect even one of these, and your score will plateau.
1) Task Achievement (Task 1) & Task Response (Task 2)
This is the foundation of your score. If you don’t answer the question properly, strong vocabulary won’t save you.
Task 1: Task Achievement (Academic) — Describe the Visual Accurately
In Academic Task 1, you must describe and summarise visual information (charts, graphs, tables, maps, processes). No opinions. No speculation.
What band levels look like (simplified)
- •
Band 9: Complete and accurate overview + all key features + clear comparisons
- •
Band 8: Strong overview + key features and comparisons (minor omissions possible)
- •
Band 7: Overview present + most key features (some inaccuracies/omissions)
- •
Band 6: Overview may be unclear/incomplete + limited comparisons
- •
Band 5: Overview weak/missing + key features missing/irrelevant
What this means in real writing
1) The overview is non-negotiable Every Task 1 needs a clear overview paragraph (usually the second paragraph). It summarises the main trends or big features.
2) Key features + comparisons matter more than small details Don’t list every number. Choose what’s significant and compare it clearly.
3) Accuracy is essential Don’t invent figures or misread trends.
Practical tip (Task 1)
Before writing, spend 2–3 minutes doing this:
- •
Identify the biggest trend(s)
- •
Find highest/lowest values
- •
Pick 2–3 strong comparisons
- •
Write the overview first, then build body paragraphs around those points
Task 2: Task Response — Answer the Prompt Clearly and Fully
In Task 2, you respond to an argument, problem, or viewpoint. You must develop ideas, support them, and maintain a clear position.
What band levels look like (simplified)
- •
Band 9: Fully addresses all parts + well-developed, focused position
- •
Band 8: Fully addresses all parts + strong position consistently supported
- •
Band 7: Addresses all parts + clear position, some parts less developed
- •
Band 6: Addresses all parts, but development may be uneven or unclear
- •
Band 5: Partially answers + weak development/unclear position
What this means in your essay
1) Address ALL parts of the question If it says “Discuss both views and give your opinion”, you must do all three.
2) Your position must be clear State it in the introduction and maintain it throughout.
3) Develop ideas with reasons + examples Don’t just assert. Explain why and give a real example.
Practical tip (Task 2)
Spend 5 minutes planning:
- •
Intro: paraphrase + thesis (your position)
- •
Body 1: main idea + reason + example
- •
Body 2: second main idea + reason + example
- •
Conclusion: summarise + restate position
2) Coherence and Cohesion (Organisation + Flow)
This criterion is about how easy your writing is to follow.
What band levels look like (simplified)
- •
Band 9: Logical structure + seamless flow + cohesive devices used naturally
- •
Band 8: Clear structure + range of cohesive devices used appropriately
- •
Band 7: Logical structure, but linking may feel slightly mechanical
- •
Band 6: Organisation present, but flow is sometimes unclear/repetitive
- •
Band 5: Weak progression + linking often incorrect or missing
How to improve coherence fast
- •
Use clear paragraphing (one main idea per paragraph)
- •
Write topic sentences (first sentence states the paragraph’s focus)
- •
Use cohesive devices naturally (don’t force “Moreover” everywhere)
- •
Use referencing (this/these/it/they) to reduce repetition
IELTS Tutor tip: When reviewing your writing, highlight each paragraph’s main idea in 5 words. If you can’t, the paragraph is unfocused.
3) Lexical Resource (Vocabulary Range + Accuracy)
This is not about “big words”. It’s about precise, natural, correct vocabulary.
What band levels look like (simplified)
- •
Band 9: Wide, precise vocabulary + natural phrasing + rare errors
- •
Band 8: Wide range + strong control of word choice/collocations
- •
Band 7: Good range + some less common items, occasional errors
- •
Band 6: Enough vocabulary, but repetition + frequent word-choice errors
- •
Band 5: Limited range + frequent errors that reduce clarity
How to improve vocabulary without risking mistakes
- •
Learn collocations (e.g., make a decision, significant increase)
- •
Learn topic vocabulary (education, environment, health, technology)
- •
Use synonyms carefully (only if you can control them)
- •
Avoid forcing “advanced” words that you can’t use naturally
IELTS Tutor tip: Build a personal vocabulary list by topic and practise using each word in 2–3 sentences, not just memorising definitions.
4) Grammatical Range and Accuracy (Structure + Control)
This criterion rewards both:
- •
Variety (different sentence types)
- •
Accuracy (fewer errors)
What band levels look like (simplified)
- •
Band 9: Wide range + accurate, flexible control + rare minor errors
- •
Band 8: Wide range + strong control, small errors don’t affect meaning
- •
Band 7: Variety of structures + frequent error-free sentences
- •
Band 6: Some complex attempts, but errors are frequent
- •
Band 5: Limited structures + frequent errors that harm clarity
What to practise for Band 7+
- •
Complex sentences done correctly
- •
Relative clauses (which, that, who)
- •
Subordinate clauses (although, because, while, whereas)
- •
Conditionals (If… then…)
- •
Controlled passive voice (only where it fits)
Practical grammar tip
When you edit your essay, do this quick check:
- •
Circle verb tenses
- •
Underline subjects
- •
Check subject–verb agreement
- •
Fix run-on sentences and sentence fragments
- •
Check punctuation (commas, full stops)

How to Improve Your IELTS Writing Score (Practical Plan)
Here’s the most effective way to use the band descriptors in real life:
- •
Print or save the descriptors Mark your own writing against them honestly.
- •
Analyse high-scoring model answers Don’t copy—identify why they score well: structure, overview, development, vocabulary.
- •
Practise under timed conditions Task 1: 20 minutes Task 2: 40 minutes
- •
Get feedback (this is where improvement happens) A good reviewer will show you patterns you can’t see yourself.
- •
Improve one criterion at a time Example week:
- •Week 1: Task Response (answer + development)
- •Week 2: Coherence (paragraphing + linking)
- •Week 3: Vocabulary (collocations + precision)
- •Week 4: Grammar (error patterns + sentence variety)
- •
Build topic vocabulary strategically Environment, education, technology, society, work, health.
- •
Write consistently Aim for 2–3 Task 2 essays per week + 2 Task 1 reports.
- •
Rewrite after feedback Rewriting is the fastest way to turn feedback into a higher band score.
- •
Master task types
- •Task 1: line, bar, pie, table, map, process
- •Task 2: opinion, discussion, problem/solution, advantages/disadvantages
Key Takeaways
- •
IELTS Writing is scored using four criteria, equally weighted.
- •
Task response matters most because it determines whether you answered properly.
- •
Coherence is about structure and flow, not fancy linking words.
- •
Lexical resource is about precision + collocations, not “big words”.
- •
Grammar is about range + control, not perfect complexity.
- •
Improvement comes from targeted practise + feedback + rewriting.
