OET Writing Word Count
OET writing requires approximately 180-200 words. Going significantly over or under this range can cost you marks. The word count guidance is published by Cambridge Boxhill Language Assessment (CBLA) in the official OET preparation materials and reflects the length expected for professional clinical correspondence.

Official OET Word Count Requirements
The OET writing sub-test gives candidates 45 minutes to write a professional letter of approximately 180-200 words. Unlike IELTS, which specifies minimum word counts (150 and 250 words), OET provides a target range rather than a strict minimum.
Too Short
Under 150 words
Likely missing essential clinical information. Insufficient detail for the reader to act on your request.
Ideal Range
180-200 words
Sufficient detail to convey all relevant clinical information concisely. Demonstrates good content selection judgement.
Too Long
Over 230 words
Likely includes irrelevant information or repetition. Signals poor content selection and clinical judgement.
Important clarification: The 180-200 word range refers to the body of the letter, from the opening purpose statement through to the closing paragraph. The standard greeting ("Dear Dr Smith") and sign-off ("Yours sincerely") are not typically included in this count. This guidance is based on the official OET preparation materials published by Cambridge Boxhill Language Assessment.
Why Word Count Matters for Your Score
Word count is not a criterion in itself, but it directly affects multiple assessment areas. Understanding this connection helps you see why staying within the recommended range is strategically important.
Conciseness & Clarity
An overly long letter is rarely concise — it repeats points and pads with detail the reader does not need. An overly short letter omits necessary information. Both pull this criterion down.
Content
This criterion assesses your ability to select the relevant information from the case notes. Including everything demonstrates poor judgement about what matters, not thoroughness.
Organisation & Layout
Appropriate letter length is part of professional letter-writing conventions. A 300-word letter does not look or read like standard clinical correspondence.
Time Management
Writing too many words consumes time you need for planning, reviewing, and correcting errors. Candidates who write 250+ words often run out of time for proofreading.
Genre & Style
Professional clinical letters are concise by convention. A verbose letter signals unfamiliarity with the genre expectations of healthcare correspondence.
Language
More words mean more opportunities for grammar and vocabulary errors. A concise, accurate letter scores higher than a lengthy letter with scattered mistakes.
5 Practical Tips to Stay Within the Word Count
These strategies help you write a letter that is both comprehensive and concise. Practising them during your preparation will make them automatic on exam day.
Plan Before You Write
Spend the first 5 minutes reading case notes, identifying the purpose, selecting relevant content, and noting the reader. Planning prevents you from including everything and then trying to cut words later, which wastes time and creates disjointed writing.
Prioritise Information Ruthlessly
Not every detail in the case notes deserves a place in your letter. Prioritise recent and clinically relevant information over historical background. A referral letter about post-surgical rehabilitation does not need to detail the patient's full medical history unless it directly affects the request.
Include
- Current clinical situation
- Reason for the letter
- Details the reader needs to act
- Relevant medications and allergies
Consider Omitting
- Detailed social history (unless relevant)
- Historical conditions (unless affecting care)
- Routine observations (unless abnormal)
- Information the reader already has
Avoid Repetition
Repetition is one of the most common causes of excessive word count. Candidates often state information in the opening paragraph and then repeat it in the body. Each piece of clinical information should appear only once, in the most appropriate location.
Repetitive
"I am writing to refer Mr Khan for a cardiology review. Mr Khan requires a cardiology review because of recurrent chest pain."
Concise
"I am writing to refer Mr Khan for a cardiology review following recurrent episodes of chest pain."
Use Concise Professional Language
Concise does not mean telegraphic. It means expressing ideas efficiently without unnecessary padding. Avoid filler phrases and wordy constructions that add length without adding clinical value.
at the present moment in time
currently
due to the fact that
because / as
in order to
to
it is important to note that
(omit or start directly)
he was found to be suffering from
he presented with / was diagnosed with
Allocate Your Time Strategically
Time allocation directly affects word count. Candidates who start writing immediately without planning tend to write too much because they include everything without filtering. A structured time plan helps you maintain control over both content and length.
Read case notes, identify purpose, select relevant content, note the reader
Write opening paragraph with clear purpose statement (20-30 words)
Write body paragraphs with selected clinical information (120-140 words)
Write closing, review for errors, check overall length (20-30 words for closing)
What Happens If You Write Too Much or Too Little?
Writing Too Much (230+ words)
Exceeding the recommended word count does not automatically trigger a penalty, but it typically indicates underlying problems that will affect your scores across multiple criteria.
Lower Content Selection Score
Including irrelevant information suggests you could not identify what the reader needs. This directly affects Content and Conciseness & Clarity.
Weaker Organisation
Longer letters are harder to structure logically. Important information can get buried among unnecessary details, affecting Organisation & Layout.
More Grammar Errors
Every additional sentence is an opportunity for grammar mistakes. Longer letters statistically contain more errors, which affects the Language score.
Time Pressure
Writing 250+ words leaves less time for reviewing and correcting errors. Many candidates who write too much submit without proofreading.
Writing Too Little (Under 150 words)
A very short letter almost always results in lower scores because it cannot contain enough clinical information to fulfil the task requirements effectively.
Incomplete Task Fulfilment
A letter under 150 words is unlikely to contain a clear purpose, sufficient clinical background, and a specific request. The reader cannot act effectively on incomplete information.
Insufficient Clinical Detail
Key patient information may be missing. The receiving clinician would not have enough context to provide appropriate care or follow-up.
Limited Vocabulary Demonstration
Fewer words mean fewer opportunities to demonstrate vocabulary range and accuracy, which directly affects the Language criterion.
Sparse Cohesion Opportunities
Very short letters have fewer sentences to connect, making it difficult to demonstrate the cohesive devices that examiners assess.
Word Count Breakdown by Letter Section
While there are no official per-section word counts, the following breakdown reflects the typical structure of a well-balanced OET letter within the 180-200 word target. These are guidelines based on analysis of high-scoring letters, not rigid rules.
Opening / Purpose Statement
State clearly why you are writing and identify the patient. This should be a single sentence that tells the reader exactly what to expect from the letter.
Example / Guidance
"I am writing to refer Mrs Chen, a 72-year-old retired teacher, for a physiotherapy assessment following her recent hip replacement surgery on 15 February."
Body / Clinical Information
Present relevant patient background, current clinical situation, treatment received, and any important findings. This is where content selection matters most. Include only information the reader needs to act on your request.
Example / Guidance
Cover relevant medical history, admission details, investigations and results, treatment provided, current status, and any ongoing concerns. Organise by clinical relevance, not by case note order.
Closing / Request
State your specific request or recommendation. Offer to provide further information. End with a professional sign-off. The request should flow logically from the clinical information presented.
Example / Guidance
"I would be grateful if you could arrange an appointment within the next two weeks. Please do not hesitate to contact me should you require any further information."
Note on the greeting and sign-off: The standard elements ("Dear Dr Smith" at the top and "Yours sincerely, [Your Name], [Your Title]" at the bottom) sit outside the body word count. Keep these brief and conventional. Avoid lengthy introductions before the purpose statement or extended closings after the request.
Frequently Asked Questions
What happens if I go over the word count in OET writing?
There is no automatic penalty for exceeding the word count. However, writing significantly more than 200 words typically indicates poor content selection, which affects your scores in Content, Conciseness & Clarity, and Organisation & Layout. Examiners expect concise, relevant clinical correspondence.
Is 250 words too many for an OET letter?
While there is no strict upper limit, 250 words is generally considered too many. The recommended range is 180-200 words. At 250 words, you are likely including information that is not essential for the reader, which can lower your content selection score.
Do examiners actually count the words in OET writing?
Examiners do not count every word individually. They assess the overall length and whether it is appropriate for the task. A noticeably short or long letter will be evident and will affect your scores in relevant criteria such as Content, Conciseness & Clarity, and Organisation & Layout.
Does the greeting and sign-off count toward the OET word count?
The standard greeting (Dear Dr Smith) and closing (Yours sincerely) are not typically counted as part of the main word count. The 180-200 word guidance refers to the body of the letter, from the purpose statement through to the final paragraph.
