For many nurses, the OET Writing sub-test feels like the most unpredictable part of the examination. Some candidates complete countless practice letters, memorise templates and learn sophisticated vocabulary, yet continue to receive a Grade C+. Others, despite having only average English proficiency, consistently achieve a Grade B or even Grade A.
The difference often lies in one fundamental misunderstanding.
OET Writing is not simply an English writing test—it is an assessment of professional healthcare communication.
OET Writing for Nurses: Why Good English Alone Won’t Get You a High Score
The exam is designed to evaluate whether you can communicate patient information clearly, accurately and appropriately to another healthcare professional so that they can continue the patient’s care safely and efficiently.
This means that grammatical accuracy, although important, is only one part of the picture. Examiners are equally interested in your ability to decide what information to include, what to omit, how to organise it, and how to adapt your language for the intended reader.
Understanding this shift in perspective is often what separates an average letter from a high-scoring one.
Think Like a Healthcare Professional—Not an Examination Candidate
Many candidates approach OET Writing as though they are writing an academic essay.
They focus on using advanced vocabulary, long sentences and complex grammatical structures because these are often rewarded in traditional English examinations.
OET is different.
Imagine you are referring a patient to a specialist. That specialist has several patients waiting, limited time and one important question:
“What do I need to know in order to manage this patient safely?”
Your letter should answer that question as efficiently as possible.
Before writing your first sentence, pause and ask yourself:
- Who is my reader?
- Why am I writing to them?
- What decisions will they need to make after reading this letter or what actions will they need to perform after reading this letter?
Every sentence you include should help answer one of those questions.

The Most Important Skill Is Not Writing—It Is Selecting Information
One of the biggest misconceptions among candidates is that every case note must appear somewhere in the final letter.
This is neither necessary nor desirable.
Real healthcare professionals do not communicate by copying entire medical records into referral letters. They exercise clinical judgement by selecting only the information that will help the recipient provide ongoing care.
The OET Writing sub-test expects candidates to demonstrate the same judgement.
For example, when referring a patient for diabetic management, the recipient is likely to need information such as:
- the reason for referral
- significant medical history
- current diagnosis
- recent investigations
- treatment already provided
- current medications
- requested follow-up
Routine observations or historical details that have no bearing on future management may simply distract the reader.
A useful question to ask throughout the writing process is:
“Will this piece of information influence the recipient’s management of this patient?”
If the answer is no, it may not belong in your letter.
Your Purpose Paragraph Shapes the Entire Letter
Experienced healthcare professionals usually understand why they have received a letter within the first few seconds of reading it.
Your recipient should not have to search for the purpose.
A weak opening might read:
I am writing regarding Mrs Patel.
Although grammatically correct, it tells the reader very little.
Compare this with:
I am writing to refer Mrs Patel for ongoing diabetic management following her recent admission with poorly controlled Type 2 diabetes.
The second example immediately establishes:
- why the letter has been written,
- the patient’s current clinical situation, and
- the recipient’s expected role.
Once the purpose has been clearly established, every subsequent paragraph becomes easier to organise because the direction of the letter has already been defined.
Organisation Is About Helping the Reader—Not Following a Template
One of the biggest misconceptions surrounding OET Writing is that there is only one “correct” structure for every letter.
In reality, there isn’t.
Organisation is not about following a fixed template. Instead, it is about presenting information in the order that best supports the recipient’s clinical decision-making.
Every paragraph should answer the question:
“What does the reader need to know next?”
The most appropriate organisation depends on the purpose of the letter, the recipient and the patient’s clinical situation.
For example, if a patient is being referred because of an acute deterioration, it may be appropriate to establish the current problem immediately before providing background information. In another case, the patient’s long-term medical history may be essential to understanding the current presentation.
The goal remains the same: minimise the effort required by the reader while maximising clarity.
In Gurleen Khaira’s OET Writing Strategy Guidebook, three commonly used organisational approaches are discussed. While this list is not exhaustive, it illustrates how different clinical situations may call for different ways of organising information.
Problem–Solution Organisation
This structure is useful when the letter revolves around a clearly defined clinical problem and the management or intervention required. The problem is introduced first, followed by relevant background information, treatment already provided and the action requested from the recipient.
Hierarchical Organisation
Some situations require the writer to prioritise information according to its clinical significance. The most important issues are presented first, followed by supporting details of decreasing importance. This approach is particularly useful when the recipient needs to identify critical information quickly.
Chronological Organisation
Where understanding the sequence of events is essential, arranging information in time order allows the reader to follow the patient’s clinical journey logically and appreciate how previous management has resulted in the current situation.
These are not rigid templates.
Experienced writers often combine different organisational approaches within the same letter. The best organisation is simply the one that enables the recipient to understand the patient’s situation quickly and continue care without unnecessary effort.

Case Notes Are Reminders—Not Ready-Made Sentences
Another common mistake is copying case notes directly into the letter.
Case notes are intentionally brief because they are written for the healthcare professional recording them.
Professional correspondence requires complete, coherent sentences.
Case Notes
- Admitted 12 May
- Chest pain
- ECG normal
- Symptoms resolved after GTN
A professional letter would read:
Mr Brown was admitted on 12 May with complaints of chest pain. His ECG findings were normal, and his symptoms resolved following treatment with glyceryl trinitrate.
Notice that the information is no longer simply listed. Instead, it has been transformed into natural professional communication while preserving clinical accuracy.
Professional Language Means Precise Language
Many candidates believe that using sophisticated vocabulary automatically leads to a higher score.
Not necessarily.
Healthcare professionals value communication that is clear, concise and precise.
Less appropriate
The patient got better after medicine.
More appropriate
The patient’s symptoms improved following treatment.
The second sentence is not stronger because it uses more difficult words. It is stronger because it communicates the clinical outcome more accurately.
Professional language should improve precision—not impress the examiner.
Grammar Is About Communicating Meaning—Not Demonstrating Complexity
Candidates often believe they must use as many complex sentences as possible to achieve a high score.
This is another misconception.
OET examiners are not rewarding grammatical complexity for its own sake. They are assessing whether your grammatical choices are appropriate for the communicative purpose.
Every sentence structure should be selected because it communicates the relationship between ideas more effectively.
A simple sentence is often the best choice when presenting a single important clinical fact.
The patient remains haemodynamically stable.
A compound sentence is appropriate when two ideas deserve equal emphasis.
The wound has healed well, and the patient has regained full mobility.
A complex sentence becomes useful when one idea supports, explains or provides context for another.
As the patient’s blood glucose levels remained poorly controlled despite medication, she has been referred for specialist diabetic management.
Here, the subordinate clause explains the reason for the referral while ensuring that the referral itself remains the main focus.
Similarly, choosing the appropriate tense depends on the clinical meaning you wish to convey.
The past simple is generally used for completed events.
The patient underwent surgery last week.
The present perfect connects previous events to the patient’s current situation.
The patient has experienced worsening breathlessness over the past month.
The past perfect may be needed when describing an event that occurred before another event in the patient’s history.
These grammatical choices are not merely technical. They help the reader understand the timeline of events and the relationship between different aspects of the patient’s care.
Strong OET writers therefore ask themselves:
“Which grammatical structure communicates this information most accurately?”
—not—
“How can I make this sentence more complicated?”
Clarity Begins Within the Sentence
Organisation does not operate only at paragraph level.
It also influences the way individual sentences are constructed.
Experienced writers package information so that familiar or contextual information prepares the reader before introducing new or clinically significant information.
Less effective
Poorly controlled diabetes resulted in a below-knee amputation, and the patient is now being referred.
More effective
Following a below-knee amputation secondary to poorly controlled diabetes, the patient is being referred for ongoing rehabilitation.
The second sentence introduces the clinical context before presenting the current purpose of the letter, making it easier for the reader to process the information.
Small decisions like these contribute significantly to cohesion and readability.
Common Habits That Prevent Higher Scores
Candidates who struggle to achieve Grade B often display similar writing habits.
These include:
- copying case notes directly
- including every detail instead of selecting relevant information
- delaying the purpose until later in the letter
- following memorised templates regardless of the scenario
- organising information mechanically rather than logically
- using advanced vocabulary that reduces clarity
- writing long sentences simply to sound more academic
Improving these habits usually produces greater improvements than memorising additional vocabulary.
Practical Ways to Improve Your Writing
Instead of writing complete letters every day, focus on developing the individual skills that contribute to high-quality professional communication.
For example:
- Practise selecting only the relevant case notes for different recipients.
- Rewrite abbreviated case notes into natural professional sentences.
- Compare different ways of organising the same set of information.
- Experiment with different sentence structures and consider why one communicates more effectively than another.
- Review completed letters from the perspective of the recipient rather than the writer.
These activities develop the clinical judgement and communication skills that OET is designed to assess.

Final Thoughts
Achieving a high score in OET Writing is not about memorising templates or filling your letter with sophisticated vocabulary.
It is about thinking like a healthcare professional.
Every decision you make—what information to include, how to organise it, which grammatical structure to use and how to express it—should be guided by one principle:
Will this help the recipient understand the patient’s situation and continue their care safely and efficiently?
When you begin writing with the reader’s needs in mind rather than the examiner’s expectations alone, your letters become clearer, more purposeful and more professional.
Ultimately, that is exactly what OET Writing is designed to reward.
