Cohesion in OET Writing
Cohesion is assessed under the Organisation & Layout criterion in OET writing. Many candidates lose marks not because of grammar errors, but because their letters read as disconnected lists of facts rather than flowing professional correspondence.

What Cohesion Means in OET Writing
Cohesion refers to how ideas are connected within and across sentences and paragraphs. In OET letters, cohesion ensures the reader can follow clinical information smoothly and understand the logical relationships between facts.
Cohesion vs Coherence
Cohesion is about the specific linguistic devices (linking words, pronouns, substitution) that connect sentences. Coherence is the broader logical organisation of ideas. Both matter, and both are measured under the Organisation & Layout criterion.
Why Cohesion Matters Clinically
In real healthcare correspondence, a well-cohesive letter allows the receiving clinician to quickly understand the patient's situation. Disconnected information increases the risk of misunderstanding and delays in patient care.
How Examiners Assess It
CBLA-trained assessors evaluate whether the candidate uses appropriate cohesive devices, whether ideas flow logically, and whether the reader can follow the letter without re-reading. Natural, varied cohesion scores higher than mechanical overuse of connectors.
Grade B Expectation
At Grade B level, candidates are expected to demonstrate competent use of cohesive devices with logical progression between sentences. Minor awkwardness is acceptable, but the overall flow should be clear and professional.
Linking Devices for OET Letters
Effective cohesion relies on choosing the right linking device for the logical relationship between ideas. Here are the key categories with examples appropriate for clinical correspondence.
Time and Sequence
subsequently, following this, on admission, at the time of discharge, prior to, since then, on [date]
Time connectors are essential in OET letters because clinical information must be presented in chronological order.
Addition and Elaboration
additionally, furthermore, in addition, it is also worth noting, he/she also
Use addition connectors when listing related clinical information. Avoid starting every sentence with the same connector.
Contrast and Concession
however, nevertheless, despite this, although, while
Contrast connectors signal a change in direction. They are particularly useful when describing unexpected clinical developments.
Cause and Result
consequently, as a result, therefore, due to, owing to, given that
Cause-result connectors are important for explaining clinical reasoning and justifying requests.
Purpose and Request
in order to, so that, with a view to, I would be grateful if, I would appreciate
Purpose connectors are central to the request section of OET letters and directly support the Purpose criterion.
Paragraph Flow in OET Letters
Cohesion operates at two levels: within paragraphs (sentences connecting to each other) and between paragraphs (each paragraph leading logically to the next). Both contribute to the examiner's assessment.
Opening paragraph establishes purpose and context
Begin with a clear purpose statement that tells the reader why you are writing and who the patient is. This sets the framework for everything that follows.
Background paragraph provides relevant history
Connect to the opening by providing the clinical background that supports your purpose. Use time connectors to establish chronology and addition connectors for related conditions.
Current situation paragraph describes recent developments
Transition from history to the present using temporal markers. This paragraph should explain what has changed or what is currently happening that prompted the letter.
Request paragraph states what is needed
Link the current situation to your specific request using cause-result connectors. The request should flow logically from the information presented. Use appropriate polite forms.
Closing paragraph offers professional sign-off
Conclude by summarising key points if necessary and providing contact details. This creates closure and signals the end of the communication.
Common Cohesion Errors That Cost Marks
Listing Without Connecting
The most common cohesion error in OET writing. Candidates list clinical facts one after another without showing how they relate to each other or to the purpose of the letter.
- • Sentences that read like bullet points
- • No logical progression between facts
- • Missing cause-effect relationships
Overusing the Same Connector
Repeating 'In addition' or 'Moreover' at the start of every sentence creates mechanical, unnatural writing. Examiners look for varied and appropriate use of cohesive devices.
- • Starting every sentence with 'Also'
- • Using 'However' for non-contrasting ideas
- • Inserting connectors where none are needed
Unclear Pronoun References
Using 'he', 'she', 'it', or 'this' without a clear antecedent creates ambiguity. In clinical correspondence, clarity is essential to avoid misunderstanding.
- • Ambiguous 'it' or 'this' references
- • Pronoun confusion with multiple people
- • Missing antecedent for 'which' or 'that'
Poor vs Good Cohesion: A Comparison
Poor Cohesion
Issue: Each sentence stands in isolation. There are no linking devices, no pronoun variety, and no logical flow. The letter reads like a list of disconnected facts rather than professional correspondence.
Strong Cohesion
Strength: Information flows logically from background to admission to findings to request. Cohesive devices (following, on admission, subsequently, given these findings) connect ideas naturally. Pronoun use and relative clauses reduce repetition.
Frequently Asked Questions
What is cohesion in OET writing?
Cohesion refers to how sentences and paragraphs are connected through linking devices, pronoun referencing, and logical sequencing. It is assessed as part of the Organisation & Layout criterion. Good cohesion means the reader can follow your letter smoothly.
What is the difference between cohesion and coherence in OET?
Cohesion refers to the specific linguistic devices used to connect sentences (linking words, pronouns, substitution), while coherence refers to the overall logical flow and organisation of ideas. A letter can have cohesive devices but still lack coherence if the ideas are presented in an illogical order.
Which linking words should I use in OET letters?
Use linking words appropriate for clinical correspondence. For time: 'subsequently', 'following this'. For addition: 'additionally', 'furthermore'. For contrast: 'however', 'nevertheless'. For cause/result: 'consequently', 'therefore'. Choose connectors that genuinely reflect the relationship between ideas.
How does poor cohesion affect my OET writing score?
Poor cohesion directly affects your score in the Organisation & Layout criterion. Letters that read as disconnected lists of facts will receive lower marks. Examiners look for smooth, logical progression where each sentence connects naturally to the next.
