The direct answer
IELTS Writing is scored by certified examiners using four equally weighted criteria: Task Achievement/Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The section comprises two tasks, with Task 2 carrying double the weight of Task 1. The individual criterion scores for both tasks are combined to produce an overall Writing band score from zero to nine.
Key takeaways
- Task 2 carries twice the mathematical weight of Task 1 toward your overall Writing band score.
- Each task is evaluated independently against four official criteria, each accounting for twenty-five percent of that task's score.
- The four scoring criteria are Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
- Relying on memorised templates and forced complex vocabulary reduces coherence and lexical precision scores.
- The final Writing section score is aggregated and rounded in accordance with standard IELTS band calculation conventions.
Section Structure and Weighting Between Task 1 and Task 2
The IELTS Writing component, across both Academic and General Training modules, consists of two distinct writing tasks. Task 1 differs by module: Academic candidates must describe, summarise, or explain visual data, processes, or diagrams, whereas General Training candidates write a personal, semi-formal, or formal letter. Task 2 requires an extended essay responding to a prompt, argument, or problem across both test versions.
Test takers must recognise that marks are not split evenly across the two tasks. Task 2 contributes approximately two-thirds of the total Writing section score, while Task 1 contributes the remaining one-third. Mathematically, your performance on the essay exerts twice the influence on your final Writing band score compared to your report or letter, making strategic time management and preparation essential.
The Four Official Assessment Criteria Explained
Certified examiners evaluate responses using standardized band descriptors established by the official test partners. Each task receives an individual band score from zero to nine across four core assessment criteria:
- Task Achievement (Task 1) or Task Response (Task 2): Evaluates how fully the candidate addresses all parts of the prompt, presents a clear overview in Task 1, and develops a well-supported position in Task 2.
- Coherence and Cohesion: Assesses the logical sequencing of ideas, systematic paragraphing, and the natural use of cohesive devices and referencing without mechanical overuse.
- Lexical Resource: Examines the range, precision, and contextual appropriateness of vocabulary, including collocation awareness, academic phrasing, and spelling accuracy.
- Grammatical Range and Accuracy: Evaluates the variety of sentence structures, grammatical control, punctuation accuracy, and the proportion of error-free sentences produced.
Comparative Breakdown of Criteria Across Tasks
Although the four assessment domains apply to both tasks, their practical application varies slightly depending on whether the candidate is producing a data synthesis or an extended argumentative essay.
| Criterion | Task 1 Application | Task 2 Application |
|---|---|---|
| Task Achievement / Response | Presenting a clear overview and highlighting key trends and comparisons without personal opinion. | Establishing a clear position throughout, fully addressing all prompt prompts, and developing ideas with support. |
| Coherence and Cohesion | Structuring descriptive comparisons or stages logically using sequential and comparative transitions. | Constructing structured body paragraphs with central topic sentences, progressive flow, and precise transitions. |
| Lexical Resource | Employing precise vocabulary for trends, proportions, comparative metrics, and process stages. | Using topic-specific academic vocabulary, nuanced collocations, and varied stylistic phrasing. |
| Grammatical Range and Accuracy | Combining passive constructions, complex comparative clauses, and accurate numerical phrasing. | Utilising conditional clauses, complex subordinations, modal verbs, and diverse structures to sustain argument. |
Step-by-Step Writing Band Score Calculation
Examiners and scoring algorithms apply a precise mathematical progression to translate individual criteria ratings into the final Writing band score:
- 1Score Task 1: The examiner assigns an individual band score (0–9) for each of the four criteria, which are averaged equally to establish the raw Task 1 band score.
- 2Score Task 2: The examiner assigns individual band scores across all four criteria for the essay, averaging them equally to yield the raw Task 2 band score.
- 3Apply the Weighted Formula: The Task 2 score is doubled, added to the Task 1 score, and the resultant sum is divided by three to reflect the two-thirds weighting.
- 4Round According to Official Protocol: The resulting average is rounded to the nearest whole or half band in accordance with official IELTS band calculation rules.
Performance Patterns Across Saudi and GCC Student Profiles
Students across Saudi Arabia and the GCC region exhibit distinct writing profiles rooted in their educational backgrounds. Candidates from national and public school curricula frequently possess solid structural knowledge but often struggle with linear argumentative essay development and rhetorical cohesion, directly impacting their Task Response and Coherence scores.
Conversely, students from international pathways such as the International Baccalaureate (IB), American Diploma, and British IGCSE/A-Levels typically demonstrate stronger lexical fluency but may lose marks through unstructured rhetorical prose or neglecting the formal objectivity demanded in Task 1 data reports. Aligning individual preparation with these specific diagnostic patterns ensures balanced progression across all four criteria.
How Writing Mechanics Influence Sub-Scores
Achieving band scores of 7.0 and above requires understanding how subtle mechanical choices impact examiner evaluations. In Lexical Resource, inserting obscure vocabulary with incorrect collocations harms scores rather than raising them; natural, precise academic phrasing is preferred. Similarly, within Grammatical Range and Accuracy, producing complex sentences only benefits your score if a substantial majority of those sentences remain entirely error-free.
Paragraph design fundamentally drives the Coherence and Cohesion criterion. Every body paragraph in Task 2 should present a single, clearly articulated central theme backed by logical supporting sentences. Over-relying on mechanical transitional templates at the start of every sentence signals a lack of organic cohesive control, capping the candidate at intermediate band thresholds.
Illustrative Writing Band Score Calculation Walkthrough
To illustrate how criterion ratings combine into an overall section band, consider the following simulated student profile across both tasks:
- Task 1 Criterion Ratings: Task Achievement = 6.0, Coherence and Cohesion = 6.0, Lexical Resource = 7.0, Grammatical Range = 6.0. Task 1 Average = 6.25.
- Task 2 Criterion Ratings: Task Response = 7.0, Coherence and Cohesion = 7.0, Lexical Resource = 7.0, Grammatical Range = 6.0. Task 2 Average = 6.75.
- Weighted Formula: (Task 1 + (Task 2 × 2)) ÷ 3 = (6.25 + (6.75 × 2)) ÷ 3 = (6.25 + 13.5) ÷ 3 = 19.75 ÷ 3 = 6.58.
- Final Band Allocation: The calculated figure of 6.58 rounds in accordance with official test conventions to an overall Writing band score of 6.5.
Common mistakes to avoid
- Omitting a clear, comprehensive overview in Academic Task 1, which automatically restricts the Task Achievement score to lower band thresholds.
- Spending excessive time on Task 1 at the expense of Task 2, which carries two-thirds of the total Writing score.
- Relying on memorised introductory templates and formulas, which trained examiners easily spot and discount from lexical assessment.
- Forcing esoteric vocabulary into sentences where the context or collocation is unnatural, degrading both lexical and grammatical precision.
- Addressing only one aspect of a multi-part essay prompt, which prevents the essay from achieving full marks under Task Response.
Advice from our academic team
Study the official public band descriptors systematically to understand exactly what examiners require across each criterion and level.
Prioritise producing completely error-free complex sentences over writing overly convoluted sentences that introduce structural ambiguity.
Proportion your writing practice time to mirror official weighting, dedicating approximately two-thirds of your effort to Task 2 essays.
Seek diagnostic feedback from experienced instructors who evaluate your work by providing individual sub-scores for all four scoring criteria.

Frequently asked questions
Are Task 1 and Task 2 weighted equally in the Writing section?
No, Task 2 carries double the mathematical weight of Task 1. Task 2 accounts for approximately two-thirds of your overall Writing band score, while Task 1 accounts for one-third, making Task 2 the primary driver of your result.
What happens if a response falls below the recommended length?
Writing an underdeveloped response generally prevents a candidate from fully explaining ideas or covering necessary data points. This directly lowers the Task Achievement or Task Response score due to insufficient depth and detail.
Does poor handwriting or crossed-out text lower the Writing band score?
Handwriting aesthetics are not directly graded, provided the text remains fully legible to the examiner. However, if words cannot be deciphered, your Lexical Resource and Grammatical Accuracy marks will suffer. Clear, legible strikethroughs are entirely acceptable.
How does scoring differ between General Training and Academic Writing?
Task 2 is assessed using the exact same essay criteria across both modules. The only scoring difference lies in Task 1, where General Training evaluates the appropriate social or formal tone of a letter, while Academic evaluates the objective reporting of visual data.
Can a student challenge and request a remark of their Writing band score?
Yes, candidates can submit an Enquiry on Results (EOR) through the official test partners to have their writing remarked by a senior examiner. If the reassessment leads to a higher band score, a revised Test Report Form is issued following official policies.
