A referral letter can lose marks before the assessor reaches the second paragraph if its purpose is vague. This OET writing referral letter guide will help you turn detailed case notes into a focused clinical document that tells the receiving professional exactly why the patient needs further care.
For healthcare professionals planning registration or employment abroad, OET Writing is not a test of advanced vocabulary alone. It tests whether you can communicate safely, selectively and professionally in a real workplace situation. A well-written referral letter shows that you understand what the next clinician needs to know, and what can be left out.
What an OET referral letter must achieve
A referral letter is written when a patient requires assessment, treatment or specialist input beyond your current care. Your reader may be a consultant, physiotherapist, community nurse, dietitian or another relevant professional. The letter should make their next action easy.
This means your purpose must be clear from the opening. Do not make the reader search for it through a long clinical history. State who you are referring, where they are being referred and why. For example: “I am referring Mr Rahman for urgent orthopaedic assessment and management of persistent right knee pain following a workplace injury.”
That sentence gives the reader the patient, destination, level of urgency and clinical reason. It also sets the direction for every detail that follows.
OET assessors evaluate your letter through six areas: Purpose, Content, Conciseness and Clarity, Genre and Style, Organisation and Language. These criteria are connected. Even accurate medical information can reduce your score if it is poorly selected, repeated or presented in an unsuitable order.
OET writing referral letter guide: read the case notes strategically
Candidates often begin writing as soon as they finish reading the notes. This is risky. Case notes may include irrelevant historical details, routine observations and information that does not influence the referral decision. Your task is not to reproduce the notes. It is to make a professional judgement about relevance.
Before writing, spend a few minutes identifying three things: the referral purpose, the reader’s likely needs and the information that supports the requested action. If a detail does not help the receiving professional assess or manage the patient, it may not belong in the letter.
For a physiotherapy referral, the reader may need the onset and progression of symptoms, functional limitations, examination findings, medication or pain management already tried, and the treatment requested. A childhood illness or an unrelated consultation from several years ago is usually unnecessary.
Pay close attention to dates. OET case notes frequently contain a sequence of consultations, test results and changing symptoms. Instead of copying every date, group events logically: “Over the past six weeks”, “Since her previous review” or “Despite two weeks of conservative management”. Use exact dates only when they are clinically important.
Decide what to include and what to leave out
Strong content selection is one of the clearest differences between a letter that sounds competent and one that feels like a list. Include relevant symptoms, key findings, significant history, current treatment and the reason for referral. Exclude repeated information, routine normal findings and background details that do not affect the next clinician’s decision.
There is no benefit in making a letter longer merely to show language range. OET expects a concise letter, generally around 180 to 200 words. A shorter letter can perform well when it is complete, clear and appropriate. A longer letter may work only if every sentence earns its place.
A reliable structure for referral letters
A clear structure protects both your time and your score. The reader should be able to understand the situation quickly, even when reviewing many referrals during a busy shift.
Begin with the date, recipient details and an appropriate salutation. Use the patient’s full name, date of birth where provided, and relevant identifying information. Then open with a direct purpose statement.
The next paragraph should explain the current problem. Describe the relevant symptoms, their duration, severity and impact on daily life. Follow this with the most useful clinical background: examination results, investigations, risk factors, diagnosis or treatment already provided.
In the final paragraph, state the requested action clearly. Avoid weak endings such as “Please see this patient.” Instead, make your expectation specific: “I would appreciate your assessment and recommendations for further management” or “Could you please review her suitability for supervised rehabilitation?”
Close professionally with “Yours sincerely” when the recipient is named, or “Yours faithfully” when they are not. Keep the style formal, respectful and clinical throughout.
Write for the reader, not for the case notes
A referral letter is not a medical record. It is targeted communication between professionals. This distinction affects grammar, vocabulary and tone.
Use factual, precise language. “The wound is painful and appears infected” is more useful than “The wound is not very good.” However, excessive technical language can also make a letter difficult to read. Choose terminology that the intended professional would naturally use, and do not force complex phrases where plain clinical English is better.
Use linking language to show progression and cause. Phrases such as “however”, “therefore”, “despite this”, “as a result” and “given her worsening mobility” help the reader understand why referral is required now. They are more effective than presenting unrelated facts in separate sentences.
Maintain an objective tone. You may write, “Ms Akter reports increasing breathlessness on exertion”, rather than “Ms Akter is very worried about her breathing.” If anxiety itself is clinically relevant, include it with an appropriate reason.
Common mistakes that reduce OET Writing marks
The first common mistake is an unclear purpose. If the opening only says that a patient has been under your care, the reader does not know why they are receiving the letter. State the referral reason immediately.
The second is copying too many notes. Candidates sometimes include every consultation, normal observation and repeated symptom. This makes the important information harder to find and can affect Conciseness and Clarity.
The third is using a generic request. A receiving professional needs to know whether you want diagnosis, treatment, assessment, follow-up or advice. Be specific, particularly when the case notes indicate urgency.
The fourth is disorganised chronology. A letter that jumps from present symptoms to distant history and back again feels difficult to follow. Usually, present issue first, relevant background next, then the action requested is the safest order.
Finally, avoid informal or emotionally loaded expressions. OET is a professional communication test. Your language should reflect the standards expected in an international healthcare setting.
Use the 45 minutes with control
OET Writing gives you five minutes to read and plan, followed by 40 minutes to write. Treat the reading time as part of the task, not as optional preparation. Underline the referral purpose, relevant changes in the patient’s condition, current management and the expected next step.
During writing, aim for a clear draft rather than trying to create perfect sentences one by one. Leave a few minutes at the end to check patient details, tense consistency, spelling, paragraphing and word count. A missing date, incorrect pronoun or confused medication detail can affect the professionalism of an otherwise strong letter.
Timed practice is particularly valuable because many candidates understand the format but struggle to make quick selection decisions. Regular mock writing tasks, followed by detailed feedback, can reveal patterns such as over-writing, weak purpose statements or unnecessary case-note repetition. At NextStep, guided OET preparation can help candidates build this decision-making skill through structured practice and individual support.
A final check before you submit
Read your letter once as the receiving clinician. Can you identify the referral purpose in the first paragraph? Do you understand the patient’s relevant problem, what has already been done and what you are expected to do next? If the answer is yes, your letter is likely focused in the right way.
The best referral letters do not try to impress with every fact in the case notes. They make the next stage of patient care clearer. Practise that professional judgement consistently, and your OET Writing score can begin to reflect the capable healthcare communicator you already are.
