Understanding how your writing is assessed is one of the most useful steps you can take when preparing for IELTS. You might have strong English vocabulary and a good understanding of grammar, but if you do not answer the question fully or organise your ideas clearly, your IELTS Writing band score may remain below your target.

The IELTS Writing test is assessed using four main criteria: Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each criterion measures a different aspect of your writing, so improving your score requires more than learning advanced words or memorising essay templates.

In this guide, you will learn what the IELTS Writing band descriptors mean, how examiners assess Task 1 and Task 2, what distinguishes different band levels, and how to use the criteria to improve your writing.

Quick answer: To improve your IELTS Writing band score, answer every part of the task, develop relevant ideas, organise your response logically, use vocabulary accurately and demonstrate a range of grammatical structures with good control. Task 2 carries twice the weight of Task 1 in the overall Writing score, making effective essay preparation particularly important.

What Are IELTS Writing Band Descriptors?

IELTS Writing band descriptors are official assessment descriptions that explain the qualities associated with different levels of writing performance.

They help examiners evaluate how effectively a candidate responds to a task, communicates ideas, uses vocabulary and controls grammar. Rather than awarding marks simply for the number of advanced words or complex sentences in an essay, examiners assess the overall quality of the response against defined criteria.

The descriptors apply to both IELTS Academic and IELTS General Training, although the Task 1 requirements differ between the two test types.

For IELTS Academic, Task 1 involves describing visual information, such as a chart, table, graph, map or process. For IELTS General Training, Task 1 involves writing a letter. Task 2 requires an essay for both versions.

Understanding the descriptors is useful because they help you identify the specific weaknesses that may be limiting your score.

The Four IELTS Writing Assessment Criteria

IELTS Writing is assessed using four criteria. Task 1 and Task 2 use closely related assessment frameworks, but the first criterion has a different name and task-specific requirements.

Assessment criterion	What it measures
Task Achievement (Task 1) / Task Response (Task 2)	How fully and appropriately you complete the task and address its requirements
Coherence and Cohesion	How logically you organise ideas and connect information
Lexical Resource	The range, accuracy and appropriateness of your vocabulary
Grammatical Range and Accuracy	The variety and accuracy of your grammatical structures

Each task is assessed independently. The four criteria are equally weighted within each task, but Task 2 contributes twice as much as Task 1 to the overall IELTS Writing score.

1. Task Achievement and Task Response

The first criterion evaluates whether you have done what the question asks.

For IELTS Academic Writing Task 1, Task Achievement focuses on selecting and reporting relevant information, identifying key features and presenting an appropriate overview.

For General Training Task 1, it also considers how effectively you fulfil the purpose of the letter, cover the required bullet points and use an appropriate tone.

For Task 2, Task Response evaluates how fully you answer the essay question, develop and support your ideas, present a clear position where required, and remain relevant to the task.

What can lower your score?

• Ignoring one part of a multi-part question
• Presenting ideas without explaining or supporting them
• Giving an unclear or inconsistent position in an opinion essay
• Missing the main trends or comparisons in an Academic Task 1 report
• Failing to cover the required bullet points in a General Training letter
• Including irrelevant information that does not help answer the task

How to improve: Before writing, underline the instruction words and identify every part of the task. Decide what information or arguments you must include, then check your response against that list before finishing.

2. Coherence and Cohesion

Coherence and Cohesion measures how clearly your ideas are organised and how effectively the reader can follow your response.

Coherence relates to the logical development and arrangement of ideas. Cohesion relates to how sentences and ideas are connected through language, including linking words, pronouns and other referencing devices.

A strong response has a clear progression from one idea to the next. Each paragraph should contribute to the purpose of the task.

What can lower your score?

• Paragraphs that contain unrelated ideas
• Ideas presented in an illogical order
• Excessive or inaccurate use of linking words
• Unclear references that make the reader unsure what a pronoun refers to
• Repeating the same point instead of developing the argument

How to improve: Plan the purpose of each paragraph before writing. In Task 2, for example, you might use one body paragraph to explain your first main argument and another to develop a second argument. Use linking expressions only when they clarify the relationship between ideas.

Remember that adding words such as moreover, furthermore and consequently does not automatically make an essay coherent. The underlying logic must be clear.

3. Lexical Resource

Lexical Resource assesses how effectively you use vocabulary to express your meaning.

This includes the range of words and expressions you can use, the accuracy of your word choices, the appropriateness of collocations and the control of spelling and word formation.

You do not need to use complicated vocabulary in every sentence. Accurate and natural language is often more effective than an advanced word used incorrectly.

What can lower your score?

• Repeating basic vocabulary unnecessarily
• Using words that do not fit the intended meaning
• Incorrect collocations
• Inappropriate informal or overly elaborate language
• Frequent spelling and word-formation errors

How to improve: Learn vocabulary in context. Instead of memorising isolated words, study common combinations such as address a problem, pose a challenge, play a significant role and have a negative impact on. Practise using them in original sentences.

For example, the sentence below is clear and natural:

“Public transport can reduce traffic congestion and improve access to employment.”

Using several rare synonyms for reduce or improve would not necessarily make the sentence better.

4. Grammatical Range and Accuracy

Grammatical Range and Accuracy measures the variety of structures you use and how accurately you control them.

A strong response may contain simple and complex sentences, subordinate clauses and a variety of grammatical forms. However, complexity is useful only when the sentence remains accurate and clear.

What can lower your score?

• Frequent subject–verb agreement errors
• Incorrect verb tenses
• Missing or incorrect articles
• Sentence fragments and run-on sentences
• Incorrect complex sentence structures
• Punctuation mistakes that affect clarity

How to improve: Identify your recurring grammar errors and focus on correcting them. Practise combining ideas with subordinate clauses, relative clauses and conditional structures, but do not make every sentence unnecessarily complicated.

Compare these examples:

Less effective: “People use cars because public transport are not convenient and it cause traffic.”

Improved: “People often rely on cars because public transport is not always convenient, which can contribute to traffic congestion.”

The second sentence expresses the relationship between the ideas more clearly and demonstrates better grammatical control.

IELTS Writing Band Descriptors: What Do Bands 5, 6, 7 and 8 Mean?

The official descriptors explain performance at each band in detail. The table below provides a practical summary of the general differences between Bands 5, 6, 7 and 8.

These descriptions are simplified learning guidance, not replacements for the official descriptors. A script must be judged against the full criteria, and performance can differ across the four assessment areas.

Band	General writing characteristics	Common development priority
Band 5	The response may address only parts of the task, with limited development, uneven organisation or frequent language errors.	Answer the complete task and develop ideas more clearly.
Band 6	The main requirements are generally addressed, but some ideas may be insufficiently developed and language or organisation may be inconsistent.	Improve support, paragraph progression and language accuracy.
Band 7	The response addresses the task appropriately, with logically organised ideas, sufficient vocabulary and a variety of grammatical structures. Some errors or lapses may remain.	Improve precision, consistency and the quality of idea development.
Band 8	The response covers the task sufficiently and relevantly, with strong organisation, flexible vocabulary and a wide range of structures that are generally well controlled.	Refine accuracy, precision and control while maintaining clear communication.

What Does IELTS Writing Band 5 Look Like?

At Band 5, a candidate may understand the general topic but struggle to fulfil all the requirements of the task. Ideas may be presented without sufficient explanation, while vocabulary and grammar errors can make parts of the response difficult to follow.

For example, an essay might state that public transport is beneficial but provide little explanation of why it is beneficial or how it affects people.

Priority: Learn to answer the exact question, organise the response into purposeful paragraphs and explain each main idea with relevant support.

What Does IELTS Writing Band 6 Look Like?

A Band 6 response generally addresses the main requirements, but some aspects may be less developed or less precise than they need to be.

The candidate may present a clear opinion and relevant arguments, yet the supporting examples may be limited. Vocabulary may be sufficient for the task, although word choice and grammatical accuracy can be inconsistent.

Priority: Develop arguments more fully, make connections between ideas clearer and correct recurring grammar and vocabulary errors.

What Does IELTS Writing Band 7 Look Like?

A Band 7 response generally covers the requirements of the task and presents ideas in a logical sequence. Vocabulary is sufficient for flexibility and precision, and a range of grammatical structures is used with some control.

There may still be occasional inaccuracies, awkward collocations or lapses in cohesion. These do not necessarily prevent the reader from understanding the response.

Priority: Strengthen the development of ideas, improve the precision of word choice and reduce repeated errors while maintaining a natural writing style.

What Does IELTS Writing Band 8 Look Like?

A Band 8 response covers the task appropriately and sufficiently. Ideas are well organised, vocabulary is used flexibly to communicate precise meanings, and a wide range of grammatical structures is generally well controlled.

Occasional errors may still occur, but they typically have limited impact on communication.

Priority: Focus on precise task fulfilment, nuanced vocabulary, effective paragraph development and consistent grammatical control. Avoid adding complexity simply to make the writing appear more advanced.

How IELTS Writing Task 1 Is Assessed

The first task has different requirements depending on whether you take IELTS Academic or General Training.

IELTS Academic Writing Task 1

Academic Task 1 requires you to describe, summarise or explain information presented in a visual form, such as a graph, chart, table, map or process diagram.

Your response should select the important information rather than describe every detail.

To strengthen Task Achievement:

• Introduce the visual information accurately.
• Include a clear overview of the main trends, stages or differences where appropriate.
• Select the most relevant data or features.
• Make accurate comparisons when the visual information supports them.
• Avoid adding personal opinions or unsupported explanations.

For example, if a chart shows that public transport use increased while car use declined, your report should highlight that overall pattern and support it with relevant figures.

A list of individual numbers without a clear overview may make it harder for the reader to understand the main message.

IELTS General Training Writing Task 1

General Training Task 1 requires you to write a letter in response to a situation. Depending on the prompt, the letter may be personal, semi-formal or formal.

To strengthen Task Achievement:

• Make the purpose of the letter clear.
• Address every required bullet point.
• Include enough detail to fulfil the purpose.
• Use an appropriate tone and level of formality.
• Organise the information so the reader can follow it easily.

For example, if you are writing to complain about a service, explain the problem, provide relevant details and state what action you would like the recipient to take.

A grammatically accurate letter may still lose marks if it fails to address an important part of the prompt.

How IELTS Writing Task 2 Is Assessed

Task 2 requires you to write an essay responding to a point of view, argument or problem. The task may ask you to give an opinion, discuss two views, examine advantages and disadvantages, or explain a problem and propose solutions.

Because Task 2 carries twice the weight of Task 1, preparing for essays should be an important part of your IELTS Writing study plan.

Task Response: Answer Every Part of the Question

Start by identifying exactly what the prompt requires.

Consider this example:

“Some people believe that university education should be free for everyone. To what extent do you agree or disagree?”

A complete response needs a clear position and relevant reasoning to support it. Simply describing the benefits of university education without addressing whether it should be free would not fully answer the question.

Coherence and Cohesion: Build a Logical Argument

Each body paragraph should have a clear purpose. A useful structure is to introduce the main point, explain it and provide a relevant example or consequence.

For instance, a paragraph arguing that free university education can improve access should explain how removing tuition fees may reduce a financial barrier. It could then develop the point by discussing students from lower-income households.

The example should support the argument rather than merely repeat it.

Lexical Resource: Choose Precise Vocabulary

Topic-specific vocabulary can help you express ideas clearly, but it must fit the context.

For an education essay, expressions such as access to higher education, tuition fees, financial barriers and educational opportunities may be useful.

The goal is not to insert as many advanced expressions as possible. It is to communicate your argument accurately and naturally.

Grammatical Range and Accuracy: Combine Variety with Control

A strong essay uses a suitable mixture of sentence structures. Simple sentences can communicate important points clearly, while complex sentences can show relationships between causes, consequences and contrasting ideas.

For example:

“Although university education can be expensive, financial support may allow more students to pursue higher education.”

This sentence expresses a contrast clearly. You should use similar structures when they help your argument, not simply to demonstrate grammatical complexity.

How Is the IELTS Writing Band Score Calculated?

Each Writing task is assessed separately using its four relevant criteria. The four criteria are equally weighted within each task, and Task 2 contributes twice as much as Task 1 to the overall Writing score.

A simplified way to understand the weighting is:

• Task 1 contributes approximately one-third of the Writing score.
• Task 2 contributes approximately two-thirds of the Writing score.

This is why an essay that responds effectively to the question can make a substantial contribution to your result. However, a strong Task 2 response does not eliminate the need to prepare for Task 1.

The exact overall band is determined through IELTS scoring procedures, so do not assume that averaging informal estimates from practice essays will always reproduce your official result.

Example of Why Task 2 Matters More

Imagine a candidate receives an estimated Band 6 in Task 1 and Band 7 in Task 2.

Because Task 2 has twice the weighting, the weighted task-level estimate would be:

[
\frac{6+(7\times2)}{3}=6.67
]

This calculation illustrates the weighting principle only. It is not a guarantee of the official reported band, because examiner assessments and IELTS scoring procedures determine the final result.

The practical lesson is to prepare for both tasks while allocating substantial attention to Task 2.

Common Mistakes That Can Limit Your IELTS Writing Band Score

Using Advanced Vocabulary Without Accuracy

Rare or sophisticated words do not automatically improve your score. Incorrect word choice and unnatural collocations can weaken clarity.

Better approach: Learn useful vocabulary in context and practise using it in original sentences.

Writing Without Planning

Starting immediately can lead to repetition, weak paragraph structure and arguments that do not fully answer the question.

Better approach: Spend a few minutes identifying the task requirements and planning the main purpose of each paragraph.

Memorising Complete Essays

A memorised essay may not address the actual prompt. IELTS expects you to respond to the task presented, not reproduce a prepared answer that only loosely matches it.

Better approach: Practise flexible structures and learn how to adapt your arguments to different questions.

Overusing Linking Words

Using a linking word in every sentence does not create logical progression. It can make your writing repetitive or unnatural.

Better approach: Focus on the relationship between ideas first, then use linking language where it improves clarity.

Ignoring Task 1

Some candidates focus almost entirely on Task 2 because it carries greater weight. However, Task 1 still contributes to the overall Writing score.

Better approach: Practise both tasks under realistic time limits and review the specific requirements of your test type.

Checking Only Grammar

A response can contain few grammar errors and still be weak if it does not answer the question fully or develop its ideas.

Better approach: Review your work against all four assessment criteria, not grammar alone.

How to Use IELTS Writing Band Descriptors to Improve Your Score

The descriptors are most useful when you turn them into a practical review routine.

Step 1: Identify Your Current Weaknesses

Complete a timed Writing Task 1 and Task 2 using suitable practice materials. Review each response against the four criteria.

If possible, obtain feedback from a qualified IELTS teacher, particularly for areas that are difficult to assess objectively.

Step 2: Review Each Criterion Separately

Do not ask only, “Is this a good essay?” Ask specific questions:

• Task Achievement or Task Response: Did I answer every part of the task?
• Coherence and Cohesion: Can the reader follow the progression of my ideas?
• Lexical Resource: Are my words accurate and appropriate?
• Grammatical Range and Accuracy: Do I use a suitable variety of structures with good control?

This approach helps you identify what to improve next.

Step 3: Rewrite Weak Paragraphs

Choose one paragraph that is unclear, repetitive or insufficiently developed. Rewrite it with a clearer main idea, more relevant support and more precise language.

Comparing the original and revised versions can reveal patterns in your writing that you may otherwise overlook.

Step 4: Practise Under Time Limits

The IELTS Writing test lasts 60 minutes. For Academic Task 1, candidates are advised to spend about 20 minutes, leaving about 40 minutes for Task 2. Similar time allocation is useful for General Training, although the content of Task 1 is different.

Practise under these conditions so that your planning, writing and checking strategies are realistic.

Step 5: Track Recurring Errors

Keep a record of common mistakes, such as unclear thesis statements, weak examples, repeated vocabulary or subject–verb agreement errors.

Review the list before your next practice session. Progress is easier to measure when you know which problems you are trying to correct.

Should You Take an IELTS Writing Course?

Self-study can be useful when you understand the assessment criteria and can identify your weaknesses accurately. However, many candidates find it difficult to judge the quality of their own essays, particularly when it comes to task response, coherence and the precision of language.

A structured IELTS Writing course may be helpful if:

• Your practice essays repeatedly receive similar scores.
• You are unsure why your answers do not reach your target band.
• Your ideas are relevant but insufficiently developed.
• You struggle to organise essays under time pressure.
• You need detailed feedback on grammar, vocabulary and task fulfilment.

A useful course should help you understand the descriptors, practise both Writing tasks, review your mistakes and apply feedback to new questions.

No course can guarantee a specific IELTS band score. However, structured practice and relevant feedback can help you identify weaknesses and prepare more effectively.

Frequently Asked Questions About IELTS Writing Band Scores

What are the four IELTS Writing assessment criteria?

The four criteria are Task Achievement for Task 1, Task Response for Task 2, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each criterion measures a different aspect of writing performance.

What is the difference between Task Achievement and Task Response?

Task Achievement is used for Writing Task 1 and focuses on how effectively you fulfil the task requirements. Task Response is used for Task 2 and focuses on how fully you address the essay question, develop ideas and support your position where required.

Does IELTS Writing Task 2 count more than Task 1?

Yes. Task 2 carries twice the weight of Task 1 in the overall Writing score. You should prepare for both tasks, but effective Task 2 preparation is particularly important.

How can I improve my IELTS Writing band score from 6 to 7?

Start by identifying which assessment criteria limit your performance. Common priorities include developing arguments more fully, improving paragraph progression, using vocabulary more precisely and reducing recurring grammatical errors. Feedback on complete practice responses can help identify the most relevant improvements.

Is advanced vocabulary necessary for IELTS Writing Band 7?

You need sufficient vocabulary to express ideas accurately and flexibly, but using rare words is not a requirement in itself. Appropriate word choice, natural collocations and control of meaning are more useful than forcing sophisticated expressions into your essay.

Can grammar alone help me achieve a high IELTS Writing score?

No. Grammar is only one of the four assessment criteria. You also need to address the task effectively, organise ideas logically and use vocabulary appropriately.

How can I assess my own IELTS Writing?

Use the official band descriptors to review each criterion separately. Check whether you answered the task, organised your ideas, selected appropriate vocabulary and used grammar accurately. Self-assessment can help, but feedback from a qualified teacher may reveal issues you have missed.

Should I memorise IELTS Writing templates?

It is more useful to learn flexible planning and paragraph structures than to memorise complete essays. A template cannot replace an answer that directly addresses the specific task, and a formulaic response may be less effective if it does not fit the question.

Final Thoughts: Use the Band Descriptors to Write More Effectively

The IELTS Writing band descriptors give you a clearer picture of what examiners assess. They show why a successful response needs more than good grammar or advanced vocabulary: it must address the task, communicate ideas logically and use language accurately.

Start by reviewing the four assessment criteria, then practise Task 1 and Task 2 under realistic conditions. Use feedback to identify recurring weaknesses, revise your work and track your progress over time.
