IELTS Writing Band Descriptors

Understand the four IELTS Writing criteria and see what usually needs to change as an essay moves from Band 5 towards Band 7 or Band 8.

4 core criteria

Band 5–8 study summary

Writing starts with four criteria

Task 1 and Task 2 use the same core dimensions, but the first one has a different name: Task Achievement for Task 1 and Task Response for Task 2.

Writing criterion

Task Achievement / Task Response

Task 1 is judged on Task Achievement; Task 2 is judged on Task Response. Both ask whether your answer addresses the question, presents a clear position or overview and develops the main ideas with enough support.

Can a reader see my answer to every part of the prompt?
Writing criterion

Coherence & Cohesion

This criterion covers the way your ideas are organised and connected. A stronger response has a clear paragraph purpose, a logical progression and linking that helps the reader follow the argument without noticing the mechanics.

Does each paragraph move the answer forward?
Writing criterion

Lexical Resource

Lexical Resource looks at range, precision and appropriacy. Aim for words that express the exact idea in context, with enough variety to avoid repetition and enough control to keep the meaning clear.

Are my key words precise, natural and appropriate for the topic?
Writing criterion

Grammatical Range & Accuracy

This criterion considers the variety of structures you use and how accurately you control them. Complex sentences help only when they remain easy to understand; basic sentence accuracy still matters throughout the essay.

Can I use a range of structures without making the reader work?

Band 5 to Band 8: turn the descriptors into checks

These are plain-language study notes, not a word-for-word reproduction of the official IELTS band descriptors. Official results are awarded by IELTS examiners using the full criteria.

5Band

The response shows a basic attempt, but parts of the task may be incomplete. Ideas, organisation and language control are often limited or uneven.

6Band

The main answer is generally clear and relevant. Development, cohesion, vocabulary or grammar may still be uneven, with errors that sometimes affect precision.

7Band

The response is clear, organised and sufficiently developed. It shows useful range in vocabulary and grammar, with some errors still possible but generally controlled.

8Band

The answer is well developed and easy to follow, using language flexibly and precisely. Errors are infrequent and do not normally interrupt communication.

Use the criteria on your own essay

01

Confirm the task response

Underline what the prompt asks for, then state your answer in one sentence. Clear language cannot make up for an unclear response.

02

Check the paragraph logic

Write down each body paragraph's main point and check that the explanation, example and result support it.

03

Review language control last

Do not only hunt for advanced words. Fix grammar errors that affect meaning, repeated vocabulary and unnatural collocations first.
