How to Write OET Letters That Score
Strong OET Writing starts with purpose, not with copying notes. Open with who the patient is and what you want the reader to do, cut background that changes nothing, keep a formal tone, then check the letter against the official criteria ideas (purpose, content, conciseness, organisation, language). This guide shows before-and-after examples and links to free, trainer-reviewed practice. Confirm current rules on the official OET website — requirements can change.

Purpose first (before / after)
Readers act faster when the ask is in the opening, not the last line.
Weak opening
“Mrs Khan is a 58-year-old woman who presented to clinic last Tuesday with several issues including fatigue…”
Stronger opening
“I am writing to refer Mrs Khan, a 58-year-old woman, for urgent gastroenterology review of progressive iron-deficiency anaemia.”
What to leave out of case notes
For every fact, ask: does this change what the reader should do next? If not, leave it out.
- Usually keep: red flags, current medications, allergies, key investigation results, what you have already done.
- Usually cut: resolved childhood illnesses, long lists of stable vitals, repeated social details that do not affect the request.
- Group by theme (problem → findings → management), not by the order the notes were written.
Formality rules
- No contractions in formal letters (“cannot”, not “can’t”).
- Prefer clinical precision for specialist readers; plain terms when writing to patients or carers.
- Check names, dates, and the closing request before you submit.
Plain-English criteria checklist
Official criterion names and weightings live on the OET website — confirm them there. Use this checklist as a practice aid only:
- Purpose — Is the reason for writing clear in the opening?
- Content — Did you include the facts the reader needs and drop the rest?
- Conciseness and clarity — One precise sentence beats three vague ones.
- Genre and style — Does the letter match the task (referral, transfer, discharge)?
- Organisation and layout — Logical paragraphs, readable structure.
- Language — Accurate grammar and vocabulary for the reader.
A reliable structure
- Purpose and patient identification in the opening.
- Relevant history grouped by theme.
- Current status and management so far.
- Clear request or handover close.
