Coherence and Cohesion is one of the four official scoring criteria used in the Writing section of the IELTS exam.
It measures how clearly your ideas are organized, connected, and easy to follow.
In simple terms:
- Coherence = logical flow of ideas
- Cohesion = language used to link ideas together
Where It Applies
This criterion is used in:
- IELTS Academic Writing Task One and Task Two
- IELTS General Training Writing Task One and Task Two
The Four Writing Criteria
Your writing is scored using:
- Task Achievement / Task Response
- Coherence and Cohesion
- Lexical Resource
- Grammatical Range and Accuracy
Each criterion contributes to your Writing band score.
What Coherence Means
Coherence refers to how logically your ideas are arranged.
A coherent essay or report has:
- Clear introduction
- Logical paragraph order
- Easy-to-follow progression
- Relevant supporting details
- Clear conclusion (Task Two)
Example of Good Coherence
Paragraph 1 introduces the issue.
Paragraph 2 explains first reason.
Paragraph 3 explains second reason.
Paragraph 4 concludes.
What Cohesion Means
Cohesion refers to how sentences and paragraphs are connected using linking devices and referencing language.
Examples:
- however
- therefore
- in addition
- for example
- this issue
- these changes
What Examiners Look For
They assess whether you:
- Organize ideas logically
- Use clear paragraphing
- Connect ideas smoothly
- Use linking words naturally
- Avoid repetition
- Guide the reader effectively
