OET Writing for Nurses: How to Write a High-Scoring OET Letter
For many nurses preparing for the Occupational English Test, OET Writing can feel surprisingly difficult.
You may understand the patient’s condition perfectly. You may know the correct medical terminology. You may even have strong general English skills.
But OET Writing tests something more specific: Can you select the right clinical information and communicate it clearly to another healthcare professional?
That is where many candidates lose marks.
In this guide, Outscore English looks at some of the most important skills you need to develop if you are aiming for 350+ in OET Writing.
What Do You Have to Do in OET Writing?
In the Writing sub-test, you are given a set of case notes describing a patient and a specific writing task.
Depending on the situation, you may need to write a:
- Referral letter
- Discharge letter
- Transfer letter
- Letter requesting further assessment or care
The challenge is that not everything in the case notes belongs in your letter.
Your job is to decide what the reader actually needs to know.
That means successful OET Writing is not simply about grammar. It is about clinical communication, relevance, organisation and clarity.
1. Start With the Reader, Purpose and Action
Before you start writing, ask yourself three important questions:
Reader
Who is reading this letter?
Purpose
Why am I writing to them?
Action
What do I need them to do?
Imagine you are referring a patient to a cardiologist.
Your reader does not necessarily need every detail from the patient’s medical history. They need the information that helps them understand why the patient is being referred and what you want them to assess or manage.
This decision should influence your entire letter.
2. Don’t Copy Every Case Note
One of the biggest mistakes candidates make is treating the case notes like a checklist.
The previous appendectomy may have little relevance to the current referral.
The hypertension, shortness of breath and oedema, however, could be highly relevant.
Strong OET candidates learn to select, include and filter information according to the reader and purpose of the letter.
3. Make Your Purpose Immediately Clear
The reader should not have to search through your letter to understand why you are writing.
“I am writing regarding Mr Smith, who has been attending our clinic for several years.”
“I am writing to refer Mr Smith for further cardiac assessment following increasing shortness of breath and bilateral ankle oedema.”
It immediately gives the reader three important pieces of information:
A clear purpose helps the healthcare professional quickly understand who the patient is, why you are writing and what action is required. This makes your letter much more useful in a professional healthcare context.
4. Organise Information Logically
Even when candidates choose the correct information, they sometimes present it in a confusing order.
Important previous conditions, diagnoses or treatment.
Changes in symptoms, treatment or clinical condition.
The patient’s present condition and most important findings.
Clearly communicate what you need the reader to do.
This structure can be particularly useful when describing changes in symptoms, treatment or clinical condition.
Chronological order is not always the best solution.
Sometimes the most clinically important information should appear first, followed by supporting details.
A logical structure helps the reader quickly understand the patient’s clinical story. Choosing what information should come first can dramatically improve the clarity and organisation of your OET letter.
5. Use Medical Vocabulary Carefully
OET candidates sometimes believe that using more complicated vocabulary will produce a higher score.
Choose words that communicate the correct clinical meaning.
Use language appropriate for healthcare communication.
Always consider who will be reading your letter.
When your reader is another healthcare professional, medical terminology may be completely appropriate.
Sophisticated vocabulary should never make your writing less clear.
The goal is not to impress the reader with difficult words. The goal is to communicate clinical information clearly, accurately and efficiently.
Choose vocabulary because it communicates the patient’s situation accurately and professionally — not simply because the word sounds advanced.
6. Control Your Sentences
Another common problem is trying to place too much clinical information into one sentence.
“Mrs Lee presented with abdominal pain which started three days ago and has progressively worsened although she has been taking paracetamol and she reported nausea but no vomiting and her temperature was elevated.”
“Mrs Lee presented with a three-day history of worsening abdominal pain despite taking paracetamol. She also reported nausea without vomiting and was noted to have an elevated temperature.”
The information is grouped into clear clinical ideas instead of being forced into one long sentence.
Don’t make one sentence do too much.
When several important clinical details need to be communicated, consider whether dividing them into two controlled sentences would make the information easier for the reader to understand.
The goal is not to make every sentence short. Instead, aim for controlled sentences that communicate relationships between clinical details clearly and accurately.
7. Connect Information Instead of Listing It
OET letters should read like professional communication — not case notes rewritten as separate sentences.
“She has hypertension. She takes amlodipine. Her blood pressure remains elevated.”
“Despite taking amlodipine for hypertension, her blood pressure remains elevated.”
Instead of presenting three separate facts, the sentence connects them into one clear clinical message.
Good OET writing shows relationships between clinical ideas.
Connecting information helps your reader understand cause, contrast, treatment response, progression and outcome without having to work out those relationships themselves.
Developing this skill can make your writing more concise, more professional and easier for the reader to follow.
8. Always Edit With the Reader in Mind
When you finish your letter, don’t only check your grammar. Your final review should focus on whether the letter works effectively for the reader.
Ask whether your letter is clear, relevant, organised and useful to the healthcare professional receiving it.
OET Writing Editing Checklist
The reader should immediately understand why you are writing.
Remove case-note details that do not support the purpose.
Check that all essential clinical information is included.
Make sure the information appears in a logical order.
The reader should know exactly what assessment, care or action is required.
Remove unnecessary repetition and simplify overloaded sentences.
Don’t spend your entire review searching for spelling mistakes.
Grammar and spelling still matter, but effective OET editing also means checking your purpose, content selection, organisation, clarity and requested action.
A strong final review asks more than “Did I make any mistakes?” It asks whether the reader can quickly understand the patient’s situation, the purpose of the letter and the action required.
