Official IELTS Writing Marking Criteria: Complete Guide & Band 9 Strategies

Explore Official IELTS Writing Marking Criteria: Complete Guide & Band 9 Strategies

If you want a higher IELTS Writing score, the first thing you must understand is how examiners actually mark your answers. Many test takers practise a lot, but they still lose marks because they focus on memorising essays instead of learning the marking criteria.

The good news is that IELTS Writing is not mysterious. Examiners assess your work using a fixed set of criteria, and once you understand those criteria, you can train your writing more intelligently. That means better task coverage, stronger structure, more accurate vocabulary, and fewer avoidable mistakes.

This complete guide explains the official IELTS Writing marking criteria for both Academic and General Training, shows you how the scoring works, and gives you practical Band 9 strategies you can apply immediately. It also includes examples, common mistakes, and the most useful FAQs.

For regular practice, you can also use our 120+ IELTS Practice Tests alongside this guide.

IELTS Writing overview: what the examiner looks for

The IELTS Writing test has two tasks:

• Task 1
• Task 2

You have 60 minutes in total. Task 1 should take about 20 minutes, and Task 2 should take about 40 minutes because Task 2 carries twice as much weight as Task 1 in the final Writing score.

That means Task 2 is more important, but both tasks matter. A strong score depends on writing a relevant response, organising ideas well, using a wide range of vocabulary naturally, and showing accurate grammar.

The official assessment criteria are the same in principle for both Academic and General Training Writing, though the task type is different.

The four official IELTS Writing criteria

Examiners assess each task using four criteria:

1. Task Achievement or Task Response
2. Coherence and Cohesion
3. Lexical Resource
4. Grammatical Range and Accuracy

These criteria are the foundation of your score. If one area is weak, your band score will drop even if the other areas are strong.

1) Task Achievement / Task Response

This criterion checks whether you answered the question properly.

For Task 1, it measures how fully, accurately, and relevantly you completed the task.

For Task 2, it measures how well you developed your position, answered all parts of the question, and supported your ideas with reasons and examples.

2) Coherence and Cohesion

This criterion checks how logically your writing is organised and how clearly your ideas connect.

It includes:

• paragraphing
• logical order
• linking words
• pronouns and reference words
• overall flow

3) Lexical Resource

This criterion measures your vocabulary.

Examiners look at:

• range of vocabulary
• correct word choice
• collocations
• topic-specific vocabulary
• spelling accuracy
• whether vocabulary sounds natural and appropriate

4) Grammatical Range and Accuracy

This criterion checks your grammar.

Examiners look at:

• sentence variety
• simple and complex structures
• accuracy
• punctuation
• grammar errors and how much they interfere with meaning

IELTS Writing Task 1: what is required

Task 1 is different in Academic and General Training.

Academic Writing Task 1

In Academic Task 1, you must describe visual information such as:

• graphs
• charts
• tables
• maps
• diagrams
• processes

Your job is to summarise the main features, compare data where relevant, and present the information clearly in a formal or neutral style.

You should not give opinions, speculate, or write unrelated explanations.

General Training Writing Task 1

In General Training Task 1, you must write a letter.

The letter may be:

• formal
• semi-formal
• informal

You need to respond to a situation and cover all the bullet points in the question.

You should be clear about the purpose, the tone, and the level of formality.

IELTS Writing Task 2: what is required

Task 2 is an essay in both Academic and General Training.

You may be asked to:

• present an opinion
• discuss both views
• discuss problems and solutions
• evaluate ideas
• compare arguments
• justify a position

This task is more important than Task 1 because it carries more weight in the final score. That is why clear ideas, strong development, and relevant examples are essential.

If you want to improve your overall writing foundation before practising essays, our Basic to Advanced English for IELTS page can help you strengthen grammar, sentence building, and core language skills.

How IELTS Writing is scored

Each task is marked separately, and the final Writing score is an average of Task 1 and Task 2, with Task 2 weighted more heavily.

This means:

• you cannot ignore Task 1
• you cannot rely on length alone
• you cannot use memorised content and expect a high score
• you need balance, accuracy, and relevance

A candidate who writes a long essay with weak ideas and poor organisation will still lose marks. A shorter but well-organised, relevant, and accurate response often performs much better.

Official IELTS Writing marking criteria explained in simple English

Below is a practical explanation of each criterion, with a focus on how to improve.

1) Task Achievement / Task Response

This is about answering the task fully and correctly.

For Academic Task 1, ask yourself:

• Did I describe the key features, not every detail?
• Did I highlight main trends or comparisons?
• Did I include an overview?
• Did I avoid opinions and unsupported guesses?
• Did I stay on topic?

For General Training Task 1, ask yourself:

• Did I clearly explain the purpose of the letter?
• Did I cover all three bullet points?
• Did I use the right tone?
• Did I write as a complete letter, not notes?

For Task 2, ask yourself:

• Did I answer every part of the question?
• Did I give a clear position or opinion?
• Did I develop my ideas with reasons and examples?
• Did I stay focused on the topic?
• Did I write a complete essay with a real argument?

Band 9 strategy for Task Achievement / Task Response

To reach a top band, your answer must be fully relevant and fully developed.

For Task 1:

• begin with a precise introduction
• include a clear overview
• select the most important features only
• compare data meaningfully
• avoid mechanical description

For Task 2:

• answer the question directly
• make your position clear early
• develop each main idea fully
• support ideas with examples or evidence
• keep every paragraph connected to the question

Common mistake

A very common mistake is writing what you know instead of writing what the question asks. Another common problem is giving a general opinion without development. Examiners reward relevance, not volume.

2) Coherence and Cohesion

This criterion checks how easy your writing is to follow.

A well-organised answer has a clear structure and smooth progression.

What examiners want to see

• one main idea per paragraph
• clear paragraphing
• logical order of ideas
• appropriate linking words
• correct use of reference words like this, these, it, they, such as

Band 9 strategy for Coherence and Cohesion

Use linking words naturally, not excessively.

A strong essay does not need a linking word in every sentence. Instead, the reader should move smoothly from one idea to the next.

A useful structure for Task 2 is:

• Introduction
• Body paragraph 1
• Body paragraph 2
• Body paragraph 3 if needed
• Conclusion

A useful structure for Academic Task 1 is:

• Introduction
• Overview
• Body paragraph 1
• Body paragraph 2

A useful structure for General Training Task 1 is:

• Salutation
• Purpose of the letter
• Main body paragraphs covering each bullet point
• Polite closing

Common mistake

Many students overuse linking phrases like moreover, furthermore, however, and in addition in every sentence. This makes the writing feel artificial. Use linking devices only where they improve clarity.

If you want to build stronger sentence flow and better paragraphing, our 5000+ Vocabulary Words List for IELTS Writing, Speaking, Listening and Reading Tests 2026 includes linking words, academic vocabulary, formal expressions, idioms, phrasal verbs, and useful topic vocabulary.

3) Lexical Resource

This is your vocabulary score.

A strong lexical resource means you can:

• use vocabulary accurately
• avoid repetition naturally
• choose words that fit the context
• use collocations correctly
• spell words correctly
• write in an appropriate tone

Band 9 strategy for Lexical Resource

To score highly, do not chase difficult words. Instead, focus on accurate and natural vocabulary.

Good vocabulary use means:

• using increase instead of repeating go up again and again
• using substantial or significant only when appropriate
• using collocations such as pose a challenge, take action, play a role, lead to correctly
• choosing formal language for essays and reports

Example

Weak: The number of people went very high.

Better: The number of people increased sharply.

Strong: The number of commuters increased sharply over the period, reaching its highest point in 2020.

Common mistake

Using memorised “big words” in the wrong way can lower your score. Examiners value control and accuracy more than rare vocabulary.

4) Grammatical Range and Accuracy

This criterion measures how well you use grammar.

A high score requires more than correct simple sentences. You should show control over a variety of structures.

What examiners look for

• simple sentences
• compound sentences
• complex sentences
• sentence control
• punctuation
• subject-verb agreement
• article use
• tense control

Band 9 strategy for Grammar

A strong answer usually includes a mix of sentence types:

• short sentences for clarity
• longer sentences for detail
• complex structures for comparison, cause and effect, or contrast

Example

Weak: People use mobile phones. They are useful. They help people.

Better: Mobile phones are useful because they allow people to communicate quickly and access information wherever they are.

Common mistake

Many candidates try to write only long sentences. That often leads to grammar errors. A better approach is to mix short accurate sentences with longer controlled ones.

Band 9 IELTS Writing strategies

Band 9 writing is not about being flashy. It is about being precise, natural, and controlled.

1) Answer the exact question

Do not write a similar essay that you memorised before. IELTS rewards relevance.

2) Plan before you write

Take a few minutes to decide:

• your main idea
• your position
• your paragraph structure
• your key examples

Planning helps you stay focused and avoid repetition.

3) Write a clear overview in Task 1

In Academic Task 1, the overview is crucial. It should summarise the main trends or features without too much detail.

4) Develop ideas instead of listing them

One strong idea is better than three weak ideas.

For Task 2, each body paragraph should explain one central point with support.

5) Keep vocabulary natural

Use precise words that fit the topic. Avoid awkward memorised phrases.

6) Use grammar that you control

Complex grammar is useful only when it is accurate. Clear writing usually scores better than risky writing.

7) Check your work

In the last few minutes, check:

• word count
• missing articles
• verb agreement
• spelling
• punctuation
• paragraphing
• whether you answered the question fully

Common IELTS Writing mistakes that lower your score

Task Achievement / Response mistakes

• missing part of the question
• no clear overview in Task 1
• weak or no examples in Task 2
• irrelevant ideas
• copying the question too much

Coherence and Cohesion mistakes

• no paragraphing
• ideas in the wrong order
• too many linking words
• repeated ideas
• unclear reference words

Lexical Resource mistakes

• repeating the same word too often
• using the wrong form of a word
• spelling mistakes
• unnatural collocations
• informal vocabulary in formal writing

Grammar mistakes

• sentence fragments
• subject-verb agreement errors
• incorrect verb tense
• missing articles
• punctuation problems
• overly long sentences with many mistakes

Example of a strong IELTS Task 2 approach

Question type: Opinion essay

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

A strong answer should:

• state your opinion clearly in the introduction
• develop one main reason in each body paragraph
• give examples or explanation
• keep the position consistent throughout
• end with a direct conclusion

Weak approach

• says “both sides have advantages” without choosing a real position
• gives general comments without development
• uses memorised phrases that do not fit the question

Better approach

A focused response might argue that free university education is beneficial because it improves equal access and long-term economic growth, while also recognising the financial challenge for governments. This creates a balanced but clear argument.

Example of a strong Academic Task 1 approach

Question type: Line graph

Question: The graph shows the number of visitors to a museum over a year.

A strong answer should:

• introduce what the graph shows
• give an overview of the main trend
• identify major highs, lows, and changes
• compare key time periods
• avoid describing every single point

Weak approach

• lists every number in the graph
• misses the overall trend
• includes opinions such as I think the museum became more popular because…

Better approach

The response should focus on the main rise, fall, peak, or fluctuation and present that information clearly and accurately.

FAQs about IELTS Writing marking criteria

1. How is IELTS Writing scored?

IELTS Writing is scored using four criteria: Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Task 2 carries more weight than Task 1.

2. Is Task 2 more important than Task 1?

Yes. Task 2 contributes more to your final Writing score, so you should spend more time and energy on it.

3. Do examiners count words exactly?

Examiners do not usually count every word manually, but writing below the minimum word limit can reduce your score. Task 1 should be at least 150 words, and Task 2 should be at least 250 words.

4. Can I use bullet points in IELTS Writing?

No. IELTS Writing must be a complete, connected text. Bullet points and note form are not appropriate.

5. Do I need advanced vocabulary for Band 9?

No. You need accurate, natural, and well-controlled vocabulary. Fancy words used incorrectly can hurt your score.

6. How many paragraphs should I write?

It depends on the task, but most Task 2 essays work well with four paragraphs, and Academic Task 1 usually works well with four paragraphs too.

7. Is grammar more important than vocabulary?

Both matter. A high score needs a balance of accurate grammar and suitable vocabulary.

8. Can I memorise essays for IELTS Writing?

Memorised essays are risky and often do not match the question. IELTS rewards relevant, original responses.

9. What is the best way to improve IELTS Writing quickly?

The fastest improvement comes from learning the criteria, practising under timed conditions, reviewing mistakes, and getting feedback.

10. Where can I practise IELTS Writing questions?
