How to Score Band 9 in IELTS Writing Task 2

Scoring Band 9 in IELTS Writing Task 2 is not about using fancy vocabulary or writing long paragraphs. It is about understanding exactly what the examiner is looking for and delivering it consistently across four specific criteria. In this guide, I will break down each criterion, show you the difference between Band 6 and Band 9 responses, and give you a clear path to the highest score.

#The Four Scoring Criteria

Every IELTS Writing Task 2 response is assessed on four criteria, each worth 25% of your score:

1. Task Achievement (TA) — Did you fully address all parts of the question?
2. Coherence and Cohesion (CC) — Is your essay logically organised and easy to follow?
3. Lexical Resource (LR) — Do you use a wide range of vocabulary naturally and accurately?
4. Grammatical Range and Accuracy (GRA) — Do you use a variety of sentence structures with minimal errors?

Most test-takers focus almost entirely on vocabulary and grammar while ignoring Task Achievement and Coherence. This is the single biggest reason people plateau at Band 6.

#Criterion 1: Task Achievement

At Band 9, you must present a fully developed position in response to the question, with relevant, extended, and well-supported ideas. At Band 6, candidates typically present a relevant position but fail to develop it fully.

#Band 6 vs Band 9: Task Achievement

Question: Some people believe that children should start learning a foreign language at primary school. Others think they should wait until secondary school. Discuss both views and give your opinion.

Band 6: "I think children should learn languages early because it is good for them. They can learn faster when they are young. On the other hand, some people think secondary school is better because children are more mature."

Band 9: "Proponents of early language education argue that young children possess a neurological advantage in acquiring new languages, as the brain's plasticity during formative years enables more natural phonetic development and intuitive grammatical absorption. Conversely, advocates for delayed instruction contend that secondary-school students bring superior cognitive maturity, enabling them to grasp abstract grammatical concepts and engage in comparative linguistic analysis more effectively."

Notice the difference is not just vocabulary — the Band 9 response explains why each position exists, using specific reasoning rather than vague statements.

#Key Rule for Task Achievement

Always ask yourself: "Have I explained WHY?" Every claim needs a reason, and every reason benefits from a specific example or elaboration. The formula is: Point → Reason → Example/Elaboration.

#Criterion 2: Coherence and Cohesion

This criterion assesses your essay's logical organisation. At Band 9, your ideas progress naturally, each paragraph has a clear central topic, and cohesive devices are used skillfully without being mechanical.

#Common Band 6 Problem: Mechanical Linking

Band 6: "Firstly, education is important. Secondly, it helps people get jobs. Thirdly, it improves society. In addition, it builds character. Moreover, it teaches discipline."

This reads like a shopping list. The linking words are present but add no logical structure.

Band 9: "Education serves as the foundation of individual economic mobility, equipping graduates with the skills demanded by modern labour markets. Beyond personal benefit, however, an educated populace drives broader societal progress — from higher civic participation to reduced crime rates."

The Band 9 version uses logical progression (from individual to societal benefit) rather than a list of disconnected points strung together with sequencing words.

#Paragraph Structure That Works

Use this structure for each body paragraph:

• Topic sentence — state the main idea of the paragraph
• Explanation — elaborate on the idea
• Example or evidence — make it concrete
• Link — connect back to the question or transition to the next point

#Criterion 3: Lexical Resource

Band 9 requires you to use a wide range of vocabulary with very natural and sophisticated control. This does not mean using the longest words you know. It means using precise words.

#Band 6 vs Band 9: Vocabulary

Band 6: "This is a very big problem in today's society."

Band 9: "This remains a pervasive issue in contemporary societies."

Band 6: "The government should do something to fix this problem."

Band 9: "Policymakers must implement targeted interventions to address this challenge."

Notice that Band 9 vocabulary is not obscure — words like pervasive, contemporary, and targeted interventions are common in academic writing. The key is precision: choosing the word that means exactly what you intend rather than relying on vague, general terms.

#Vocabulary Pitfalls to Avoid

• Do not memorise and force in "big words" — examiners can spot this instantly
• Avoid repeating the same word more than twice — use synonyms and paraphrasing
• Never use a word you are not confident about — one misused word damages your score more than a simple word helps it

#Criterion 4: Grammatical Range and Accuracy

Band 9 demands a wide range of structures used accurately and appropriately. You need to demonstrate control of complex sentences, not just use them.

#Structures That Signal Band 9

• Conditional sentences: "Were governments to invest more heavily in renewable energy, the long-term economic benefits would far outweigh the initial expenditure."
• Cleft sentences: "It is the lack of early intervention that makes this problem so difficult to resolve."
• Passive constructions: "Considerable attention has been devoted to this issue in recent years."
• Participle clauses: "Having considered both perspectives, I am inclined to support the former view."

The key is variety. A Band 9 essay mixes simple, compound, and complex sentences naturally. Writing only in complex sentences is just as problematic as writing only simple ones.

#Final Tips for Band 9

1. Answer the question precisely. If it says "discuss both views and give your opinion," you must do all three.
2. Plan for 5 minutes before writing. A clear plan prevents disorganised essays.
3. Write 270-300 words. Going significantly over takes time from checking and rarely adds quality.
4. Leave 3-4 minutes to proofread. Catching two or three errors can shift your GRA score by half a band.
5. Practise under timed conditions. Writing a beautiful essay in 60 minutes is irrelevant — you have 40.
