If you are aiming for a stronger band score, your writing strategy matters just as much as your grammar. This guide shows exactly how high-scoring candidates plan, structure, and review Task 2 essays, especially for IELTS Academic candidates who need precise control under pressure.
Band 9 in IELTS Writing Task 2 means your essay fully addresses the task, presents a clear and well-developed position, uses cohesive devices naturally, and demonstrates a wide range of vocabulary and grammatical structures with very few errors. Examiners assess four equal criteria: Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
💡 Expert Tip
Most students lose marks in Task Achievement — not grammar. Before you write a single word, spend 5 minutes planning your position and your two main arguments. Examiners can tell within the first paragraph whether you truly understand the question.
IELTS Writing Task 2 is marked on four equally weighted criteria, each worth 25% of your Task 2 band score. Understanding what each criterion means is the single most important step in improving your result.
Students often assume that high scores come mainly from advanced vocabulary, but persistent grammar mistakes and weak planning usually show up because the band descriptors are not being targeted deliberately.
Band 9
Fully addresses all parts of the task, presents a clear fully developed position with well-extended ideas.
Band 6
Addresses the task but some parts more fully than others.
Band 9
Information is sequenced logically, cohesive devices used so naturally the reader barely notices them.
Band 6
Arranges information coherently but mechanical use of cohesive devices.
Band 9
Full flexibility in use of vocabulary, rare errors, sophisticated collocations used naturally.
Band 6
Adequate vocabulary, some inappropriate choices, noticeable errors in word formation.
Band 9
Wide range of structures, virtually no errors, punctuation well-managed.
Band 6
Mix of simple and complex structures, some errors but communication not impeded.
The most reliable Band 9 structure is a 4-paragraph essay: Introduction (2–3 sentences), Body Paragraph 1 (main argument + evidence + example), Body Paragraph 2 (second argument + evidence + example), Conclusion (1–2 sentences restating your position). This structure satisfies all four band descriptors when executed well.
A reliable structure also makes it easier to turn a loose practice routine into a real study plan, because you can isolate introduction practice, paragraph development, and timed proofreading instead of writing full essays blindly every day.
💡 Expert Tip
Your conclusion should take no more than 3 minutes to write. Students who run out of time almost always spent too long on the introduction. Write your intro in 5 minutes maximum and move on.
Band 9 essays never drift into a general discussion of the topic. They identify the task type, every instruction in the question, and the scope of what the examiner is really asking before planning begins.
DO THIS
Identify every part of the question before writing
AVOID THIS
Writing a general essay about the topic
Your thesis should be visible early and remain stable until the conclusion. Examiners reward clarity and control, not dramatic last-minute changes of opinion that weaken Task Achievement.
DO THIS
State your view in the intro and maintain it to the end
AVOID THIS
Changing your opinion in the conclusion
Detailed support makes arguments feel credible and developed. When an example sounds concrete, your essay reads as thoughtful rather than formulaic, which lifts both Task Achievement and coherence.
DO THIS
In countries like Germany and Japan, automation has reduced manufacturing jobs by over 20% in the past decade
AVOID THIS
Many countries have been affected by this problem
Band 9 writing sounds controlled, not repetitive. A natural mix of short, longer, conditional, relative, and concessive clauses shows range without sounding forced.
DO THIS
Mix simple, compound, and complex sentences naturally
AVOID THIS
Starting every sentence with 'Furthermore' or 'Moreover'
High-scoring vocabulary is precise and appropriate, not flashy. The goal is to choose natural collocations and accurate academic wording that fits the sentence and tone.
DO THIS
Use collocations — 'mounting pressure', 'mitigate the impact', 'pivotal role'
AVOID THIS
Forcing rare words where simpler ones sound more natural
A strong paraphrase shows immediate language control and avoids the impression of memorised writing. Good candidates change both vocabulary and grammar, not just a few words.
DO THIS
Completely rephrase using synonyms and different grammar structures
AVOID THIS
Copying even a single phrase from the question — examiners are trained to spot this
Strong body paragraphs feel focused because every sentence supports the same claim. Once a paragraph starts doing two jobs, development becomes shallow and coherence starts to break down.
DO THIS
Every sentence in a body paragraph should support the topic sentence
AVOID THIS
Introducing a second argument mid-paragraph
Band 9 cohesion is almost invisible. Instead of stacking obvious linkers, strong essays guide the reader through clear logic, reference words, and naturally connected clauses.
DO THIS
Use a mix of reference words (this, these, such), conjunctions (although, while), and discourse markers (consequently, nevertheless)
AVOID THIS
Starting every sentence with 'Firstly, Secondly, Thirdly, Finally' — this is mechanical not sophisticated
The minimum is 250 words, but aiming slightly above that gives you enough room to develop both arguments properly. Once essays become too long, the risk of repetition and avoidable errors rises sharply.
DO THIS
Aim for 270–300 words — quality over quantity
AVOID THIS
Writing 380+ words — it rarely improves your score and increases error risk
Even excellent essays lose marks through small slips in articles, agreement, or plural forms. A short final review often catches the kinds of grammar errors that separate Band 7 from Band 8 or 9.
DO THIS
Check subject-verb agreement, article usage (a/the), plurals, and spelling in the final 3 minutes
AVOID THIS
Using all 40 minutes writing with no review time
Band 9 candidates do not use rare or obscure words — they use common academic words in precise collocations and varied grammatical positions. The key is using the right word in the right context, not the most impressive-sounding word.
The safest route to better vocabulary is not memorising a giant phrase list. It is learning families of expressions, then using them naturally in essays, in your Speaking Part 2 practice, and in timed review work if you are preparing for a UK visa deadline alongside your writing exam.
| Mistake | Why It Costs Marks | Fix |
|---|---|---|
| Copying the question | Examiners deduct marks for memorised language | Paraphrase every word |
| No clear position | Fails Task Achievement criteria | State your view in sentence 2 of introduction |
| Listing ideas without development | Body paragraphs need explanation + example | Use the Point-Explain-Example method per paragraph |
| Using 'Moreover, Furthermore, In addition' repeatedly | Signals mechanical cohesion — penalised at Band 7+ | Vary with reference chains and subordinate clauses |
| Writing about the wrong essay type | Discussion essays ≠ opinion essays | Identify the essay type before planning |
| Informal language | 'a lot of', 'kids', 'things', 'stuff' | Replace with 'a significant number of', 'children', 'factors', 'issues' |
| Short conclusion introducing new ideas | Penalised under Coherence | Restate only — no new arguments |
| Under 250 words | Automatic band cap at Band 5 | Always aim for 270 minimum |
“To what extent do you agree or disagree?”
Take a strong clear position — partial agreement often leads to a weaker, unfocused essay.
“Discuss both views and give your own opinion”
Give roughly equal weight to both sides before clearly stating your own view in the conclusion.
“What are the problems and what measures can be taken?”
Match number of problems to number of solutions — one problem per body paragraph with its solution.
“Discuss the advantages and disadvantages”
Avoid 'in my opinion' unless the question asks for it — pure advantages/disadvantages essays need balance.
“Why is this? Is this a positive or negative development?”
Answer BOTH parts equally — most students spend 80% on the first part and lose Task Achievement marks.
You must write a minimum of 250 words. Going under this results in an automatic band cap. Most Band 8–9 essays are between 270–310 words — quality over quantity matters more than length beyond the minimum.
Neither position scores higher than the other. What matters is that your position is clear, consistent, and well-supported with developed arguments and relevant examples throughout the essay.
Yes — IELTS examiners accept personal examples provided they are relevant and clearly support your argument. However, specific general examples ('studies in Scandinavian countries show...') tend to sound more authoritative.
Your introduction should be 2–3 sentences: a paraphrase of the question and a clear thesis statement. Do not spend more than 5 minutes on it. A longer introduction does not improve your band score.
The main differences are: Band 7 essays address all parts of the task clearly with a developed position, use a mix of cohesive devices (not just discourse markers), demonstrate less common vocabulary with occasional errors, and use complex sentences with good control and few errors.
Examiners are specifically trained to identify memorised language and will discount it from your Lexical Resource score. Learn vocabulary in context and practise using it naturally rather than memorising fixed phrases to insert.
