IELTS Writing Assessment Criteria

Overview

The International English Language Testing System (IELTS) measures a candidates ability to communicate in English across four skills: Listening, Reading, Writing, and Speaking. The Writing component is split into two tasks (Task1 and Task2) and is scored on a band scale from 0 to 9. Examiners use four distinct criteria to evaluate every response. Understanding these criteria is essential for testtakers who wish to improve their scores and for teachers who design effective preparation courses.

The Four Assessment Criteria

1. Task Achievement (Task1) / Task Response (Task2)

Task1 (Academic) requires candidates to summarise visual information (graphs, tables, maps, or diagrams). The examiner looks for:

• Complete coverage of the most important trends, comparisons, or stages.
• Accurate selection of data no irrelevant or invented details.
• A clear overview or summary that captures the main features.

Task1 (General Training) asks for a letter (formal, semiformal, or informal). Success is measured by how well the writer addresses each bulletpoint in the prompt.

Task2 (Both Academic & General) is an essay. The examiner checks whether the answer:

• Fully addresses every part of the question (opinion, advantages/disadvantages, problemsolution, etc.).
• Presents a clear position throughout the response.
• Develops ideas with relevant examples, explanation, and justification.

2. Coherence and Cohesion

This criterion evaluates the logical flow of information and how ideas are linked.

• Coherence: The overall structure (introduction, body paragraphs, conclusion) must be logical; each paragraph should focus on a single idea.
• Cohesion: Use of linking devices (however, furthermore, in contrast, etc.) should be appropriate and varied, without overreliance on simple connectors.
• Paragraphing must be clear start a new paragraph when a new point is introduced.

3. Lexical Resource

The examiner judges the range and accuracy of vocabulary.

• Demonstrate a variety of words and idiomatic expressions appropriate to the task.
• Show ability to paraphrase the question and avoid repetition.
• Maintain correct word formation (nounverbadjectiveadverb) and collocation.
• Minor spelling errors are tolerated, but frequent or serious mistakes reduce the score.

4. Grammatical Range and Accuracy

This criterion focuses on the complexity and correctness of sentence structures.

• Use a mix of simple, compound, and complex sentences.
• Apply accurate tense usage, subjectverb agreement, and article usage.
• Control punctuation (commas, full stops, colons, semicolons) effectively.
• Occasional minor errors are acceptable, but systematic errors lower the score.

Band Descriptors at a Glance

Each criterion is marked on a 09 scale; the four scores are then averaged to give the final Writing band.

Practical Tips for Maximising Your Score

Task Achievement / Task Response

• Underline the command words (e.g., discuss, compare, give reasons) before you start writing.
• Plan a quick outline 12 minutes for Task1, 34 minutes for Task2.
• Never go offtopic; if unsure, stick to the information you are confident about.

Coherence & Cohesion

• Use a consistent paragraphing model: introduction 23 body paragraphs conclusion.
• Vary linking words: instead of firstly, secondly, try To begin with, Another important point, Consequently.
• Avoid chain linking dont string together too many connectors in one sentence.

Lexical Resource

• Create a personal word bank of topicspecific vocabulary (e.g., environment, education, technology).
• Practice paraphrasing the same question in at least three different ways.
• Check spelling of common problem words (e.g., environment, accommodation).

Grammatical Range & Accuracy

• Master a handful of complex structures (relative clauses, conditionals, passive voice) and use them deliberately.
• Write sentences, then reread them aloud to spot agreement or tense slips.
• Keep a list of frequent errors you make and review it before the exam.

Sample Task2 Analysis

Prompt: Some people think that governments should invest more in public transportation, while others believe that funds should be used to improve roads. Discuss both views and give your own opinion.

How the criteria are applied

Task Response: A highscoring answer would clearly state the two positions, give reasons and examples for each, and finish with a solid personal stance.

Coherence & Cohesion: Paragraph 1 introduction; Paragraph 2 arguments for public transport; Paragraph 3 arguments for roads; Paragraph 4 conclusion. Logical linking devices such as On the one hand, Conversely, In my view help the flow.

Lexical Resource: Use topicspecific terms (infrastructure, carbon emissions, congestion, sustainable development) and synonyms (invest, allocate, devote). Avoid repetition of government.

Grammatical Range: Include a mix of simple sentences (Roads are essential for goods transport.) and complex ones (While public transport reduces pollution, it requires substantial initial capital, which many governments find difficult to allocate.).
