What this assessment checks
Coherence and Cohesion is one of the four criteria used to assess IELTS Writing. Coherence concerns the logical organisation and progression of ideas. Cohesion concerns the language that makes relationships clear: conjunctions, linking expressions, pronouns, reference words, substitution and controlled repetition. The two work together. A sensible plan can still feel rough if sentences are poorly connected, while frequent linking words cannot rescue ideas placed in an illogical order.
This page turns the public IELTS descriptors into questions you can answer with evidence. You will inspect the whole response, each paragraph and the links between sentences. You will not award yourself an official band. Only trained examiners can do that reliably. Instead, you will identify what already helps a reader, what creates effort, and which change would have the greatest effect.
Choose a recent Task 1 or Task 2 answer. Keep the original version. Assessment is most useful when you can see what you wrote under realistic time pressure, rather than quietly improving it while reading.
Understand the difference before you score anything
Coherence is the route
The response has a recognisable purpose and order. Paragraphs have distinct jobs. Information that belongs together stays together. Each sentence moves the paragraph forward, and the reader does not need to invent missing steps. In Task 1, this may mean grouping comparable features and placing the overview where it is easy to find. In Task 2, it may mean moving from a claim to an explanation and then to relevant support.
Cohesion is the connection
The language accurately signals addition, contrast, cause, result, time and reference. Pronouns have clear nouns. Phrases such as “this change” name what “this” means. Repetition keeps the topic visible without becoming mechanical. Linking expressions are selected for meaning, not inserted at the start of every sentence.
Imagine a journey. Coherence decides which places you visit and in what order. Cohesion provides the paths and signs between them. More signs do not help when the route itself goes in circles. A good assessment therefore begins with the whole response and only later looks at individual linkers.
First read: follow the response as an ordinary reader
Read once without editing. Put a small mark in the margin whenever you pause because the purpose of a paragraph is unclear, a sentence seems unrelated, or a reference word could point to more than one thing. Do not correct grammar yet. The aim is to notice the reader’s experience.
- Cover the title of your plan.
Can you still identify what each paragraph is doing from the writing itself?
- Write a five-word label beside each paragraph.
For example: “overview of main changes,” “benefit for rural workers,” or “why the policy may fail.” If a paragraph needs two unrelated labels, it may contain two competing topics.
- Draw an arrow between paragraph labels.
Explain the relationship in plain words: sequence, comparison, alternative view, reason, result or conclusion. If you cannot name the relationship, the order may need revision.
- Underline the central sentence.
In a Task 2 body paragraph, this is often a topic sentence. In Task 1, it may be the comparison that controls a group of figures.
- Circle every unexplained jump.
A jump occurs when the writer knows why two statements connect but has not made that reasoning available to the reader.
At this stage, resist counting linking words. A response may be coherent with relatively few obvious linkers because its paragraph purposes and sentence order are already clear.
Assess the whole-response organisation
For each statement below, select the description that best matches your evidence: secure, inconsistent, or not yet visible. “Secure” means the quality appears throughout the response. “Inconsistent” means it works in some places but not others. “Not yet visible” means a reader would struggle to find it.
The introduction establishes the task or position, the middle develops it, and the ending completes rather than changes the message.
Each paragraph handles one useful stage, feature group, reason, view or question part.
Earlier information prepares for what follows. Comparisons are made directly rather than separated by long lists.
A Task 1 overview is clear; a Task 2 position and required discussion are visible.
Later sentences explain, prove, qualify or extend earlier ones rather than restating them.
Record one quotation or paragraph number beside every judgement. Evidence prevents a vague conclusion such as “my organisation is bad.” You may discover that the overall plan is sound but paragraph three loses focus, which gives you a much more useful target.
Assess paragraph focus and progression
Read each paragraph alone. Ask what promise its opening makes and whether the remaining sentences keep that promise. A focused paragraph can include an example, qualification or contrast, but these details must serve the same central purpose.
State the paragraph’s useful claim or comparison.
Explain how, why or under what condition it is true.
Add evidence, a figure, consequence or concise example.
Show why the support matters to the task.
This is not a fixed sentence formula. Some paragraphs need two comparison sentences; others need a concession before the main explanation. The visual simply shows progression: each stage should add something the reader needs.
A common hidden problem: sideways movement
Consider this paragraph opening: “Public libraries remain valuable because they give low-income residents free access to information.” The next sentence says, “Libraries were first established many centuries ago.” The history may be true, but it moves sideways. A better second sentence would explain that books, internet access and quiet study space can otherwise be expensive. The paragraph then develops the stated reason.
Mark every sentence with a short function: point, explanation, evidence, example, qualification or result. If several sentences have no clear function, or if three sentences all repeat “point,” revise the progression before adding linkers.
Assess how sentences connect
Now inspect cohesion. Highlight five kinds of connection in different colours: addition, contrast, cause or result, reference, and repeated topic language. The aim is not to create a colourful page. It is to see whether one device is overused and whether important relationships remain invisible.
Meaningful conjunctions
Words such as because, although, while and if connect clauses precisely. Check that the grammar and meaning match.
Sentence linkers
However, therefore, for example and in contrast can guide the reader, but punctuation and logical fit matter.
Reference
Pronouns and phrases such as “this increase” point back clearly. A bare “this” can be vague.
Substitution
Words such as “the former,” “the latter,” “those” or “this approach” avoid clumsy repetition only when their meaning is unmistakable.
Lexical chains
Related terms keep the topic active: commuters, passengers, bus users and travellers. Variation must preserve meaning.
Controlled repetition
Repeating a key noun is often clearer than forcing a synonym or using an uncertain pronoun.
Ask of every visible connector: What exact relationship does this signal? If you cannot answer, remove it temporarily and read again. Also look for a relationship that needs no explicit linker because the sentence structure makes it clear. Natural cohesion is varied and unobtrusive.
Worked assessment: find the real source of difficulty
Before
Many cities want people to use bicycles. Firstly, bicycles reduce pollution. Secondly, bicycle lanes are expensive. Moreover, some people live far from work. Therefore, cycling is healthy. Furthermore, governments should improve transport. This can solve it.
The paragraph contains several linkers, but it is neither coherent nor well controlled. The central purpose is unclear: is it explaining benefits, obstacles or a policy recommendation? “Secondly” introduces an idea that does not form a simple list with pollution. “Therefore” incorrectly suggests that distance from work causes cycling to be healthy. “This” and “it” have uncertain references. The paragraph moves between unrelated claims without development.
After
Although cycling can reduce local air pollution, it is not a practical option for every commuter. People who live far from their workplace may be unable to cycle safely or arrive on time, particularly when routes lack protected lanes. Cities should therefore treat cycling as one part of a wider transport system rather than a complete replacement for buses and trains. Investment in connected cycle lanes can support shorter journeys, while reliable public transport remains necessary for longer ones.
The revision has a clear purpose: it explains why cycling helps but cannot meet every journey. “Although” introduces a genuine concession. “Therefore” links the limitation to the policy judgement. “Shorter journeys” and “longer ones” create a direct contrast, while “cycling,” “cycle lanes” and “public transport” keep the topic visible. The improvement comes mainly from clearer reasoning and order, not from using more linking phrases.
Evidence note
A useful assessment comment would be: “My paragraph uses many linkers, but the relationships do not always match. I will decide the paragraph’s purpose first and test each connector by naming its meaning.” This is more actionable than “use better cohesion.”
Common mistakes and practical corrections
One paragraph for the whole response
Problem: The reader cannot see where one stage or topic ends. Correction: Start a new paragraph when the central purpose changes, not after an arbitrary number of sentences.
A new paragraph for every sentence
Problem: Related explanation is broken into fragments. Correction: Keep a claim and its direct support together.
A linker at every sentence start
Problem: The writing sounds mechanical and relationships may be forced. Correction: Use sentence order, clause structures and reference as well as linkers.
Unclear pronouns
Problem: “They,” “this” or “it” could refer to several nouns. Correction: Name the noun or write a precise phrase such as “this decline in car use.”
Synonyms that change meaning
Problem: A writer replaces “government” with “authority” or “children” with “students” even when the groups are not identical. Correction: Repeat the accurate term when necessary.
Examples that become new topics
Problem: The example is interesting but does not prove the paragraph’s point. Correction: Add one sentence explaining the connection or choose a closer example.
How the assessment changes for Task 1 and Task 2
Academic Task 1
Check whether the overview presents the main patterns and whether detail paragraphs group related features. A chart’s visual order is not always the clearest writing order. If two categories move similarly, compare them together. Avoid describing every value as an isolated sentence. Time linkers should reflect real sequence, while comparison language should show exact relationships. See the published Task Achievement guide for selecting and covering key features.
General Training Task 1
Check that the letter moves naturally through its purpose and all bullet points. Paragraphing should help the recipient understand why you are writing and what action, explanation or request follows. Reference words must remain clear because the letter often mentions several people, events or arrangements.
Task 2
Check that the position progresses through relevant paragraphs and that each main idea receives explanation. The relationship between the introduction, body and conclusion should be consistent. A conclusion should complete the argument, not introduce a new reason. Use the Task Response assessment guide to check that the organised argument also answers every part of the prompt.
Turn your findings into one improvement priority
Do not try to fix everything in one rewrite. Count your evidence notes and choose the issue that affects the reader most often. If three paragraphs lack clear purposes, reorganising them matters more than replacing two repeated words. If the route is clear but pronouns regularly create ambiguity, reference should become the next target.
- Name the repeated problem.
Example: “My examples are relevant, but I do not explain how they support the main claim.”
- Choose a visible action.
After every example, write a short sentence that states its significance, then remove it only if the connection is already obvious.
- Practise on a small unit.
Repair two paragraphs before writing another full response. Focused work makes the new decision easier to repeat under time pressure.
- Reassess with the same question.
Compare the new paragraph with the original and check whether reader effort has genuinely fallen.

Practice exercises
Paragraph labels
Take a finished essay and hide the prompt. Give every paragraph a five-word purpose label. Rewrite any label that contains “and” because it may reveal two competing jobs.
Missing-step test
Draw arrows between consecutive sentences and say the relationship aloud. Add one reasoning sentence where the connection depends on knowledge the reader cannot see.
Reference audit
Circle every pronoun and demonstrative: it, they, this, these, those. Draw a line to its exact noun. Replace any reference with more than one possible target.
Linker removal
Remove all sentence-opening linkers from one paragraph. Restore only those that express a relationship the order and grammar do not already make clear.
Reordering challenge
Cut one paragraph into separate sentences. Ask a partner to arrange them. If several orders seem equally plausible, strengthen the progression.
Task 1 grouping
List the key features from a chart. Create two different groupings and choose the one that produces the clearest comparisons rather than following the chart mechanically.
Your final coherence and cohesion checklist
- The reader can identify the response’s overall direction.
- Every paragraph has one clear and useful purpose.
- Paragraph order supports the task and reduces reader effort.
- Each main point is explained or supported rather than repeated.
- Examples and figures stay connected to the paragraph’s central idea.
- Linking words express accurate relationships and are not overused.
- Pronouns and reference phrases have unmistakable targets.
- Key terms are repeated or varied without changing meaning.
- Task 1 feature groups or Task 2 arguments are easy to locate.
- The conclusion completes the message without introducing a new direction.
Read the response one final time at normal speed. A technically correct connector is not successful if the reader still has to stop and rebuild the logic. Your goal is not to make every connection obvious with a special phrase. Your goal is to make the writing feel guided, accurate and easy to follow.
