Have you ever spent months practicing IELTS essays, only to get stuck at Band 6.5?
The reason isn’t your English—it’s that you aren’t grading your essays the way official examiners do.
Whether you are targeting Band 7, 8, or 9, scoring high requires understanding the exact 4-part framework examiners use to grade every single script. In this guide, you’ll discover how the scoring criteria work, the exact mistakes holding your score back, and actionable steps to reach your target band score.
Master Lecture: Deconstructing the IELTS Writing Assessment Criteria
1. Introduction: How Examiners ACTUALLY Grade Your Essay
Welcome to today’s masterclass on the engine behind your IELTS Writing score: the Official IELTS Assessment Criteria.
Whether you are aiming for Band 7, 8, or 9, understanding how examiners apply the band descriptors to both Task 1 and Task 2 is essential. Many candidates spend months practicing writing without knowing what the examiner is looking for when grading their script.
Both Task 1 and Task 2 are assessed across four equally weighted criteria (each contributing 25% to your task score):
How IELTS Writing Is Assessed
Both IELTS Writing Task 1 and Task 2 are assessed using four equally weighted criteria. Each criterion contributes 25% to the assessment of that task. The key difference is that Task 1 is assessed for Task Achievement, while Task 2 is assessed for Task Response. The other three criteria remain the same for both tasks: Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
IELTS Writing Assessment Criteria
| Assessment Criterion | Task 1 | Task 2 | Weighting |
| Task Achievement / Task Response | Task Achievement (TA) – How well you fulfil the requirements of the task and present key features or relevant information. | Task Response (TR) – How well you answer all parts of the question and develop relevant ideas. | 25% |
| Coherence & Cohesion | How logically your ideas and information are organised and connected. | How logically your ideas and information are organised and connected. | 25% |
| Lexical Resource | The range, accuracy and appropriateness of your vocabulary. | The range, accuracy and appropriateness of your vocabulary. | 25% |
| Grammatical Range & Accuracy | The variety and accuracy of grammatical structures used. | The variety and accuracy of grammatical structures used. | 25% |
| 25% | 25% | 25% | 25% |
| Task 1: Task Achievement | Coherence & Cohesion | Lexical Resource | Grammatical Range & Accuracy |
| Task 2: Task Response | Coherence & Cohesion | Lexical Resource | Grammatical Range & Accuracy |
1. Task Achievement (Task 1) & Task Response (Task 2)
This criterion checks whether you actually answered every part of the question.
A. Mastering Task 1 (Academic Visuals & Data)
To secure a Band 7+ on Task 1, avoid listing every single number. Instead:
- Provide a Clear Overview: Summarize 2–3 major trends or high-level features in your introduction or summary paragraph without clogging it with figures.
- Select Key Features Only: Highlight significant peaks, low points, or contrast points.
- Maintain 100% Accuracy: Double-check dates, units (e.g., millions vs. percentages), and categories.
Band 6 Example: “In 2010, energy use was 20%, then in 2015 it was 25%, and in 2020 it reached 30%.”
Band 7+ Example: “Overall, while industrial energy consumption experienced a steady upward trajectory over the decade, household usage remained relatively stable.”
B. Mastering Task 2 (Essay Questions)
- Answer All Parts of the Prompt: If a prompt asks for Causes AND Solutions, failing to give equal weight to both will cap your score at Band 6.
- Maintain a Clear Position: For “To what extent do you agree or disagree?”, state your stance in the introduction and stick to it throughout.
- Avoid the Logic Leap: Don’t just state an idea—explain the cause-and-effect mechanism before giving an example.
2. Coherence & Cohesion (CC): Structure & Flow
Coherence is how clear your logic is, while Cohesion is how smoothly your sentences connect.
COHERENCE & COHESION
│
┌──────────────────────┴──────────────────────┐
▼ ▼
MACRO-COHERENCE (Logic) MICRO-COHESION (Flow)
• 1 Main Idea per Paragraph • Natural Referencing (this, these)
• Strong Topic Sentences • Varied Linking Words
• Logical Idea Progression • Avoid "Formulaic" Connectors
Pro-Tip to Boost Your CC Score:
Stop starting every sentence with overused transitions like Firstly, Secondly, Furthermore, or In a nutshell. Over-relying on these limits your score to Band 6.
- Overused (Band 6): “Governments should build hospitals. Furthermore, governments should fund schools.”
- Cohesive (Band 7+): “State authorities ought to prioritize healthcare infrastructure. Such investments, when combined with educational funding, drive long-term societal gr 1 owth.”
3. Lexical Resource (LR): Academic Vocabulary & Precision
Targeting a high vocabulary score isn’t about using long, obscure words—it’s about precise collocations and natural phrasing
Lexical Resource measures the range, accuracy, and register of your vocabulary, as well as your awareness of collocation and paraphrasing.
| Skill Area | Band 6 Performance | Band 7+ Strategy |
| Paraphrasing | Replaces words mechanically with imprecise synonyms (people $\rightarrow$ humans). | Rewrites entire clause structures while keeping exact academic context. |
| Collocations | Uses unnatural word pairings (“make a strong damage”). | Uses natural academic pairings (“exacerbate environmental degradation”). |
| Topic Vocabulary | Relies on vague words (“good things”, “big issues”). | Deploys precise topic terms (“fiscal incentives”, “demographic shifts”). |
Key Components for Band 7 and Band 8/9
4. Grammatical Range & Accuracy (GRA)
To reach Band 7 or higher, at least 50% of your sentences must be completely error-free, featuring a clean mix of sentence types:
- Simple Sentences: Ideal for crisp, high-impact topic sentences.
- Compound Sentences: Formed using conjunctions (and, but, so, yet).
- Complex Sentences: Formed using subordination (although, whereas, provided that, because).
- Advanced Structures (Band 8/9): Participial phrases (“…thereby reducing…”) and inverted conditionals (“Should the state decide to…”).
| Score | Task Achievement / Response | Coherence & Cohesion | Lexical Resource | Grammatical Range |
| Band 6 | Addresses all parts, but main ideas lack full expansion or depth. | Uses paragraphs, but overuses mechanical linking words (firstly, also). | Adequate vocabulary range; noticeable errors in word choice or collocation. | Uses a mix of simple/complex forms; frequent minor grammar/punctuation slips. |
| Band 7 | Fully covers all prompt requirements with clear, supported points. | Logically organized with smooth transitions and subtle referencing. | Good range of flexible, topic-specific vocabulary with minor errors. | Variety of complex structures; frequent error-free sentences. |
| Band 8+ | Nuanced, thoroughly developed arguments with flawless logic. | Effortless structure; seamless flow between sentences and paragraphs. | Wide, precise vocabulary with sophisticated control of collocations. | Wide range of flexible structures; majority of sentences are 100% error-free. |
B. Accuracy & Punctuation
- Error-Free Sentence Density: Band 7 requires that a majority of your sentences contain no grammatical errors.
- Punctuation Rules: Avoid run-on sentences and comma splices (joining two independent clauses with only a comma). Ensure proper use of commas after introductory subordinate clauses.
6. Matrix Comparison: Band 6 vs. Band 7 vs. Band 8 Across All Criteria
To visualize how these criteria apply in practice, review this comparative breakdown:
| Criterion | Band 6 | Band 7 | Band 8 / 9 |
| TA / TR | Addresses all parts, but some may be covered more fully than others; ideas are present but lack deep expansion. | Addresses all parts fully; presents a clear position throughout; main ideas are developed with supporting logic. | Fully satisfies all requirements; presenting a well-developed, nuanced response with logical chains of reasoning. |
| CC | Uses paragraphing, but not always logically; overuses or mechanically uses basic linking words (firstly, also). | Organizes information logically with a clear progression; uses a range of cohesive devices seamlessly. | Uses paragraphing effortlessly; cohesion is subtle and natural; referencing is clear throughout. |
| LR | Adequate range of vocabulary; makes noticeable errors in word choice, spelling, or collocation. | Uses a sufficient range of vocabulary with flexibility; demonstrates awareness of collocation and style; minor errors. | Uses a wide, precise vocabulary effortlessly; natural control of collocations; rare minor errors or slips. |
| GRA | Uses a mix of simple and complex forms; makes frequent minor grammar or punctuation mistakes. | Uses a variety of complex structures; produces frequent error-free sentences; good control of grammar and punctuation. | Uses a wide range of structures flexibly and accurately; majority of sentences are error-free; punctuation is precise. |
