What is Coherence and Cohesion in IELTS Writing Task 2 and how to reach Band 7+?

Coherence and cohesion are like identical twins in IELTS Writing — they always appear together, but they each play their own role.

• Coherence = the bigger twin responsible for logical organisation and clarity of ideas
  Your essay should be easy to follow, with a clear overall structure and a logical progression of ideas.
• Cohesion = the smaller twin responsible for how ideas are linked
  You use cohesive devises like linking words, pronouns, and reference (this, these, such, it, they, etc.) to connect sentences and paragraphs without sounding mechanical.

In IELTS Writing Task 2, Coherence and Cohesion are one of the four assessment criteria and account for 25% of your score. At Band 7+, your essay should feel well-organised, easy to read, and smoothly connected, without overused or repetitive linking phrases.

Topic sentences

Band 6: Topic sentences may be vague or too general.

Band 7: Topic sentences clearly signal the main idea of each paragraph.

Question: “Technology in education – more benefits or drawbacks?”

Band 6: “Technology has many effects on education. Firstly, it is very useful because students can use computers and the internet to find information for their homework. Secondly, technology can also be bad because students sometimes play games or use social media in class instead of listening to the teacher. Moreover, schools need to spend a lot of money on new devices and this is a big problem. In conclusion, technology is good and bad and people should think carefully about how to use it in schools.”

• A loose list of mixed ideas with basic, mechanical linkers and no clear single focus

Band 7: “One major benefit of technology in education is that it makes learning more flexible and accessible for students. Through online platforms, learners can watch recorded lessons, download notes and complete practice exercises at any time, instead of being limited to the school timetable. As a result, students who find certain topics difficult can review them several times, while faster learners can move ahead without waiting for the rest of the class. This ability to work at their own pace often leads to better understanding and greater confidence, which shows that technology can significantly improve the learning experience.”

• Develops one clear idea logically with smooth connections and a clear progression from explanation to example to result

Use a standard but effective layout:

• Introduction: paraphrase the question + give your overall position (if needed).
• Body paragraph 1: first main idea (clearly stated in the topic sentence).
• Body paragraph 2: second main idea.
• (Optional) Body paragraph 3: third main idea or a strong contrast / extra aspect.
• Conclusion: summarise main points + restate your position.

Don’t chase “creative” structures; examiners prefer clarity and logical order.

Question example: “Technology in education – more benefits or drawbacks?”

Band 6:

• Introduction: Very general, does not clearly answer “more benefits or more drawbacks”.
• Body 1: Talks about some benefits and one drawback mixed together.
• Body 2: Talks about another benefit, then suddenly mentions “in conclusion, technology is important”.
• Conclusion: Repeats some phrases, says “there are advantages and disadvantages”, but does not clearly choose one side.
  • The essay is partially coherent but feels disorganised and unclear.

Band 7:

• Introduction: Briefly introduces the topic and clearly states “technology brings more benefits than drawbacks overall”.
• Body 1: Explains first benefit (flexibility and access) with example and result.
• Body 2: Explains second benefit (engagement and motivation) with example and result.
• Body 3: Acknowledges main drawbacks (distraction and inequality) but explains why benefits are still stronger.
• Conclusion: Summarizes the main benefits and drawbacks and clearly restates that benefits outweigh disadvantages.
  • The essay has a clear progression and well-separated, focused paragraphs.

A topic sentence tells the reader what the paragraph is about. It should:

• Directly relate to the question.
• Express the main idea of that paragraph.
• Help the reader predict what is coming next.

Question example: “Technology in education – more benefits or drawbacks?”

Band 6:

“Technology affects education in many ways.”

• Too generic

Band 7:

“One major benefit of technology in education is that it makes learning more flexible for students.”

• Clearer and guides the paragraph

Think of a paragraph as a chain: each sentence should link naturally to the next.

You can:

• Explain the previous sentence: “This means that…”
• Give a result: “As a result,…”, “Therefore,…”.
• Give an example: “For instance,…”, “For example,…”.
• Add similar information: “In addition,…”, “Furthermore,…”.
• Contradict or contrast: “However,…”, “On the other hand,…”.

Avoid putting a linking word at the beginning of every sentence. That sounds forced and can lower your cohesion score.

Question example: “Technology in education – more benefits or drawbacks?”

Band 6:

“Technology has many effects on education. Firstly, it is very useful because students can use computers for information. Secondly, it is bad because students can get distracted easily. Thirdly, technology is expensive and some schools cannot afford it.”

• Linking words (“Firstly, secondly, thirdly”) are used mechanically

Band 7:

“One key benefit of technology in education is that it makes learning more flexible and accessible for students. To illustrate, online platforms allow learners to watch recorded lessons, download notes and complete practice exercises at any time, rather than being limited to the school timetable. As a result, students who struggle to keep up in class can review difficult parts several times, while those who learn faster can move ahead without waiting for others. This flexibility helps a wide range of learners to study at their own pace, which can lead to better understanding and higher levels of confidence.”

• Linking is smooth (“To illustrate”, “As a result”), not overused.

Instead of repeating key nouns again and again, use:

• it, they, this, that, these, those
• this trend, this change, this problem, such issues, these advantages, etc.

Question example: “Technology in education – more benefits or drawbacks?”

Band 6:
“Online learning is very popular. Online learning helps students study from home. Online learning is also cheap for many people.”

Band 7:
“Online learning is very popular. This method helps students study from home and, in many cases, it is also more affordable.”

Each paragraph should focus on one main idea. Mixing too many different points in a single paragraph makes the essay less coherent.

For example, for “more benefits or drawbacks?”, you might use:

• Body 1: benefits – flexibility and access.
• Body 2: benefits – engagement and motivation.
• Body 3: drawbacks – distraction and inequality (but benefits are still stronger).

Avoid putting benefits and drawbacks randomly together in one paragraph unless you are doing a deliberate contrast.

Practical Body Paragraph Writing Skills for Better Coherence in IELTS Writing Task 2

Before writing

• Do I have a simple structure? (Intro + 2–3 body paragraphs + conclusion)
• Does each body paragraph have one clear main idea?
• Have I written a clear topic sentence for each paragraph?

While writing

• Does every sentence in this paragraph support the topic sentence?
• Have I used a mix of connectors (for example, as a result, however, in addition) without putting one at the start of every sentence?
• Am I using pronouns and referencing (this, these, such problems, this trend) to avoid repeating the same nouns?

After writing

• Can I summarize each paragraph in one short sentence? (If not, it’s probably mixed or unfocused.)
• Do my paragraphs follow a logical order from start to finish?
• Are there any sentences that feel like they “jump” or don’t clearly follow the previous one?
• Did I accidentally repeat the same idea in different words in another paragraph?
• Does my conclusion clearly match and summarize the main ideas in the body paragraphs?

Coherence and Cohesion are not about using as many linking words as possible; they are about guiding the reader through your essay in a clear, logical way. By planning a simple structure, writing strong topic sentences, connecting ideas naturally, and grouping related points into focused paragraphs, you can quickly move your writing from a disorganised Band 6 style towards a confident Band 7+.
