Connectors and Cohesion in OET Writing: Linking Ideas Without Overloading
How to use connectors and cohesion devices in OET letters to improve Organisation and Language marks — without the over-linking that pushes letters into informal register.
Connectors are the most visible cohesion device in an OET letter — and the most misused. Candidates who have practised essay writing often over-connect: stacking “Furthermore”, “Moreover”, and “Additionally” in a single paragraph in an attempt to show range. This reads as essayistic rather than clinical-professional, and it costs marks under both Organisation and Language. This guide covers how connectors are assessed, which ones work in an OET letter, and how to build cohesion without over-signposting.
For the criterion that assesses cohesion most directly, see OET writing criteria.
How connectors are assessed across the six criteria
| Connector issue | Criterion affected | Impact |
|---|---|---|
| Missing connectors — ideas are abrupt and unlinked | Organisation & Layout | Drops Organisation band — reader has to infer the logical connection |
| Stacked connectors — three in one paragraph | Genre & Style | Drops Genre band — reads as essay, not professional letter |
| Wrong connector — ‘however’ where ‘therefore’ is meant | Language | Drops Language band — incorrect word choice |
| Informal connector — ‘Also’, ‘Plus’, ‘So’ at sentence start | Genre & Style | Drops Genre band — register mismatch for formal correspondence |
| Good paragraph sequencing with minimal connectors | Organisation & Layout | Raises Organisation band — coherence without visible scaffolding |
The approved connector set for OET letters
These work in professional clinical correspondence without pushing the register into essay territory:
Additive (adding a point): In addition, / Furthermore (once per letter max)
Contrast: However, / Despite [noun phrase], / Although [clause],
Causal: Therefore, / As a result, / Consequently,
Temporal: Subsequently, / Following this, / Prior to [noun phrase],
Concession: Despite [noun phrase], / While [clause],
Avoid: Moreover, Additionally, Likewise, In contrast, To summarise, Last but not least, Firstly / Secondly / Thirdly, As mentioned above, In conclusion.
The better cohesion strategy: structure over signposting
The highest-scoring OET letters rarely feel connector-heavy. They achieve cohesion through three techniques that don’t require explicit connectors:
1. Paragraph topic sentences. Each paragraph opens with a clear topic sentence that tells the reader what this paragraph contains. The connection between paragraphs is implied by the logical sequence: reason for referral → relevant history → current status → what you need from the recipient.
2. Pronoun reference. After introducing Mr Hassan in the opening paragraph, subsequent sentences use “He” and “His” without re-stating the name. This forward-linking is cohesion — invisible and appropriate to the clinical register.
3. Lexical chains. Repeating key clinical terms across the letter (“blood pressure”, “antihypertensive medication”, “cardiovascular risk”) creates a semantic thread that holds the letter together without connectors.
Before/after: the stacked connector problem
Over-connected (essays register):
Mr Al-Saif was admitted with chest pain. Furthermore, he has a significant cardiac history. Moreover, he is currently on warfarin. Additionally, his renal function has recently declined.
Correct (professional clinical register):
Mr Al-Saif was admitted with chest pain. He has a background of ischaemic heart disease and is currently anticoagulated with warfarin. Renal function has declined over the past three months, which is relevant to his anticoagulation management.
The second version has no connectors in the traditional sense — the logic is carried by paragraph structure and clinical sequencing. This is what a Band B OET letter looks like.
Practical check during proofreading
During your proofreading pass, count the number of sentence-opening connectors. If you have more than three in a letter, replace at least one with a restructured sentence that makes the connection implicit.
