10 OET Writing Tips from Expert Examiners
These strategies come from correcting over 9,500 OET letters and observing the patterns that separate Grade B (350/500) candidates from those who fall short. Each tip targets a specific area of the six official assessment criteria defined by Cambridge Assessment English. OET is recognised by healthcare regulators in the UK (NMC, GMC), Australia (AHPRA), New Zealand, Ireland, Singapore, Dubai, and Ukraine.

10 Proven Strategies for OET Writing Success
Start with a Clear, Specific Purpose Statement
The opening sentence of your letter determines the examiner's first impression and directly affects your Overall Task Fulfilment score. A vague purpose wastes the reader's time and signals weak clinical communication skills.
Avoid
"I am writing to inform you about a patient."
Better
"I am writing to refer Mrs Chen for a physiotherapy assessment following her hip replacement surgery on 12 February."
Criterion: Overall Task Fulfilment, Appropriateness of Language
Select Content Ruthlessly
Not everything in the case notes belongs in your letter. Examiners want to see that you can identify which information is relevant to your specific purpose and reader. Including everything shows poor clinical judgement, not thoroughness.
Criterion: Overall Task Fulfilment, Comprehension of Stimulus
Paraphrase Actively, Not Mechanically
Copying case notes verbatim is one of the most common reasons for low scores in Comprehension of Stimulus. However, paraphrasing does not mean changing one or two words. It means expressing the same clinical information in your own professional sentences.
Case Notes
"Hx: T2DM x 10yrs. Metformin 500mg bd. A1c 8.2%"
Paraphrased
"Mr Ahmed has a 10-year history of Type 2 diabetes mellitus, currently managed with Metformin 500mg twice daily. His most recent HbA1c was 8.2%, indicating suboptimal glycaemic control."
Criterion: Comprehension of Stimulus, Linguistic Features (Vocabulary)
Maintain Professional Tone Throughout
Your letter should read as though a senior healthcare professional wrote it. This means avoiding contractions, slang, and overly casual expressions, while also not being excessively formal or academic. Consistency is key.
Criterion: Appropriateness of Language
Manage Your 40 Minutes Strategically
Time pressure is a major factor in OET writing. Candidates who spend too long reading and planning often rush the writing and make avoidable errors. A structured approach to time allocation makes a significant difference.
Read case notes, identify purpose, select content, note the reader
Write opening paragraph with clear purpose statement
Write body paragraphs (background, current situation, request)
Review for grammar errors, missing connectors, and register issues
Criterion: All criteria (time management affects every area)
Follow a Logical Letter Structure
Organisation and Layout is a separate criterion, and a clear structure helps the reader process clinical information efficiently. Every OET letter should follow a logical progression that mirrors how healthcare professionals communicate.
Criterion: Organisation and Layout, Overall Task Fulfilment
Focus on High-Impact Grammar Areas
You do not need perfect grammar to achieve Grade B. Focus your preparation on the grammar areas that are most common in OET letters and most frequently penalised by examiners.
Criterion: Linguistic Features (Grammar and Cohesion)
Avoid These Common Pitfalls
After correcting thousands of OET letters, we consistently see the same mistakes. Being aware of these pitfalls allows you to self-check before the examiner identifies them.
Writing to the wrong reader
Always check the task instructions for who you are writing to
Including a diagnosis not in the case notes
Only report what is documented in the provided information
Ending without a clear request
Every letter needs a specific action for the reader to take
Exceeding the word count significantly
Aim for 180-200 words; excessive length signals poor content selection
Criterion: Overall Task Fulfilment, Comprehension of Stimulus
Practise with Feedback, Not Just Volume
Writing 30 practice letters without feedback is far less effective than writing 10 letters with detailed professional correction. The goal of practice is to identify your specific error patterns and eliminate them before the exam.
Criterion: All criteria (systematic practice improves every area)
Use the Review Time to Check, Not Rewrite
The final 5 minutes of your exam should be used for targeted checking, not rewriting. Trying to restructure your letter at this stage usually creates more problems than it solves. Instead, use a focused checklist.

Frequently Asked Questions
How can I improve my OET writing score quickly?
Focus on purpose and content selection first. Many candidates lose marks not because of poor English, but because they include irrelevant information or fail to state the purpose clearly. Getting professional feedback on practice letters is the most effective way to identify and fix your specific weaknesses.
How many practice letters should I write before the OET exam?
Most successful candidates write between 15 and 25 practice letters, with professional feedback on at least 5 to 10 of those. Quality of practice matters more than quantity. Writing 10 letters with detailed corrective feedback and revision is more effective than 30 letters without feedback.
What is the best time management strategy for OET writing?
Allocate 5 minutes for reading and planning, 5 minutes for the opening, 25 minutes for the body and closing, and 5 minutes for reviewing errors. The most common mistake is spending too long on case notes and rushing the actual writing.
Should I use a template for OET writing?
A flexible framework is helpful, but rigid templates can hurt your score. Examiners can identify memorised templates. Instead, learn the standard clinical letter structure and adapt it to each specific scenario.
