It is not that people failing the OET Writing sub-test have a problem with their English. People fail because they did not know the requirements of the assessment. The OET writing criteria 2026 are not a secret, and once you get to know all the criteria, your letter will stop being guesswork. Here is an overview of the entire marking rubric, the structure of the letter getting high marks and small things making a difference between grade B and C. It is for nurses, doctors, pharmacists, physiotherapists and any other healthcare professionals studying for the OET Writing test in 2023.
The Occupational English Test (OET) is conducted by the Cambridge Boxhill Language Assessment (CBLA), and the Writing sub-test is common for all professions: reading case notes and writing a letter. Easy to say but more difficult in practice as the entire process is time-limited and the marking is more strict than candidates expect.
What the OET Writing Sub-Test Actually Looks Like
You are given 45 minutes altogether. The first 5 minutes are reading time, during which you only read the case notes and make no writing. Then you get 40 minutes to plan and write your letter. The task requires you to write a letter containing about 180-200 words, most likely a referral letter, but also a discharge letter, transfer letter or advice letter according to the case scenario.
The case notes provide information about the patient. The information regarding the patient’s personal particulars, past medical history, main concern, treatment given, present status, and future plan is contained therein. You are expected to formulate all that information into a professional letter to a particular person. This addressee could be a specialist, community nurse, GP or carer, and this makes a huge difference, and we’ll talk about this later on.
Here comes the short explanation of the OET writing format 2026: read notes, identify purpose, select information, and write a clinical letter. That is what the test measures.
At Tijus Academy, we build our whole Writing programme around this reality. We do not teach generic English writing. We teach profession-specific letter writing, because a nurse writing a discharge letter and a pharmacist writing an advice letter are doing two different jobs. That focus is one reason we are considered the best OET coaching centre by the healthcare professionals we train.
The Six OET Assessment Criteria Explained
Here is the part that matters most. Your letter is marked against six official criteria. Two trained assessors mark it separately, without seeing each other’s scores. In case of wide disparities, an upper-level assessor intervenes to resolve this issue. This dual-marking explains the fact that fairness is an integral part of this process and knowing the criteria can be a definite advantage for you.
Six criteria include purpose, content, conciseness and clarity, genre and style, organization & layout, and language. Let us go through each one properly, because this is the OET assessment criteria explained in a way you can actually use.
- Purpose
Purpose asks one thing: Is the reason for your letter immediately clear? The assessor should know why you are writing within the first sentence or two. A busy specialist reading your referral does not want to hunt for the point.
The criterion purpose gets graded differently than the others. This criterion ranges from 0 to 3, while all other criteria range from 0 to 7. You have to obtain at least 2 marks out of 3 for purpose. This does not seem to be difficult; however, the majority of candidates get no points due to placing the purpose of writing somewhere in the middle of the letter or even forgetting about its expansion.
The example of a good start is as follows: “I am writing to refer Mr. James Doe, a 58-year-old man who requires regular cardiac evaluation after a myocardial infarction.” It is clear what this letter is about. That is what “immediately apparent” means.
- Content
Content checks whether you included the right information and whether it is accurate for the reader. This is where selecting case notes OET skills come in, and it is honestly the hardest criterion for most people.
You cannot copy every note into your letter. You also cannot leave out something the reader needs. The skill is selection: choosing what matters for this specific reader and this specific purpose, then leaving the rest out. If you are referring a patient for physiotherapy, the reader needs mobility details and the injury history. They probably do not need the patient’s full dietary chart.
You also must never invent information. If it is not in the case notes, it does not go in the letter. Assessors notice fabricated details immediately, and it damages your score.
- Conciseness & Clarity
This criterion asks whether your letter is an effective summary. Did you cut the irrelevant material? Is every sentence pulling its weight?
Word count is not really the point here. Relevance is. An 185-word letter that contains everything that the reader needs to know will do better than a 300-word letter which is full of repetition and digresses into unnecessary history. Even long sentences that are grammatically correct will make your reader lose interest.
It works like this: The reader is a healthcare professional with limited time. If they can read your letter once and understand the whole situation, you have done your job.
- Genre & Style
Genre & Style is about register. An OET letter is professional clinical correspondence, not a personal note and not an academic paper. The tone has to be formal without being rigid. You use proper medical terms, and your use of abbreviations is correct since the reader will know their meaning.
In case you are addressing an expert, it is okay to use shorthand terms. But in case you are giving advice to a patient or their caregiver, then the tone will have to be toned down a bit. Matching your style with that of the reader is exactly what you are supposed to do in this criterion. The most common reason for scoring low is failure to get the tone right.
- Organization & Layout
This criterion considers how easy it is for the assessor to navigate your letter. It is essential that each paragraph contains only one idea. The content should be organised logically in the order of purpose, background, current state, and request.
Proper formatting is also important. This includes right spacing between paragraphs, an appropriate greeting, and sign-off. Transitional words help to connect the logical flow of ideas. If your letter is well structured, an assessor will easily find all the necessary details in it.
- Language
It entails grammatical correctness, vocabulary usage, spelling, and punctuation. The most important thing to note is that there is no point-to-point marking on language errors. It involves examining if your language affects the meaning.
Minor mistakes with articles, tenses, or pronouns may affect clinical meaning, thus, accuracy is important. However, complex sentences are not necessary for good marks. Clear, correct, varied language beats complicated language that needs rereading. To pass, you generally need 5 out of 7 on language and on each of the other criteria apart from purpose.
What Grade B Actually Requires?
Healthcare boards generally opt for a Grade B which translates to a 350 score out of 500 in the Writing sub-test. In order to achieve Occupational English Test Grade B requirements, a candidate must score well on all six categories simultaneously. It won’t help much to have excellent grammar when your content selection skills are poor.
In practice, the two criteria where candidates most often fall short are Content and Purpose, because both require clinical judgment, not just language skill. You have to think like a healthcare professional deciding what a colleague needs to know. That is a skill you build through practice with real feedback, which is exactly what we focus on at Tijus Academy.
The OET Referral Letter Structure That Works
Since the referral letter is the most common task, let us look at a reliable structure. A good OET referral letter structure usually follows this flow.
Begin with the date, the recipient’s name and address, and a proper salutation such as “Dear Dr. Smith.” Your introductory paragraph then explains the reason for your letter and introduces the patient along with his/her age.
The body paragraphs come next. Group the information logically. One paragraph might cover relevant medical history and the chief complaint. Another might cover the current condition and recent treatment. Make sure your paragraphs focus on a single theme so that the reader can understand your case.
Your last paragraph tells the reader exactly what you would like from him/her. Do you need an assessment, management or intervention? Be direct. Then close politely with a line offering further information and a proper sign-off.
These OET letter writing tips apply across letter types, but the referral is where they matter most because it is what you are most likely to see on test day.
Common Mistakes That Pull Scores Down
A few patterns show up again and again in weak letters. Candidates copy case notes word for word instead of selecting and rephrasing. They include irrelevant detail that distracts the reader. They use the wrong register, writing to a specialist as if writing to a friend. They forget to expand the purpose, so it appears once and then disappears. And they run out of time because they did not plan before writing.
Every one of these is fixable. The fix is not more English study in the abstract. It is targeted practice against the six criteria, with someone correcting your letters and telling you exactly where you lost marks. Generic practice will not do it. This is why choosing the right OET writing course makes such a difference.
How Tijus Academy Trains You for OET Writing
If you have been searching for the best OET training online, here is what makes our approach different. The approach to the development of these four competencies is different for all. We create training that is aimed at healthcare practitioners, people who need tangible results of their hard work, not just theoretical knowledge.
For these four competencies, we create separate OET-focused modules trained by specialists of that particular competency. For Writing, that means letter-writing practice with detailed correction and feedback on every submission so you always know where you stand against the six criteria. For Speaking, we run real exam-style role-plays that mirror the profession-specific scenarios you will face. We also run regular mock tests with scoring guidance and honest trainer feedback, so there are no surprises on test day.
What we are proud of are the unique techniques we have built to make preparation stick.
Medscriba is our special writing programme, with individual sessions run by writing experts who work through your letters one-on-one. If your Content or Purpose scores keep dropping, this is where they get fixed. Lexplorer is our lexical building session, designed to grow the precise clinical vocabulary the Language and Genre & Style criteria reward.
We also run (EC)², which stands for Empathy, Explanation, and Clear Communication, a core part of both Writing register and Speaking. Our Phrasiology Jam sessions build reading skills through idioms and phrase activities, while Tuning Threshold develops the listening skills you need for the Listening sub-test. Bandorium brings you top-tip sessions led directly by our module heads, so you learn from the people who know the exam best.
For focus and mental sharpness, we run Neurosync, our brain-gym activities, because a tired mind writes weak letters. Every week we hold Thursquest, a full mock test every Thursday, so testing becomes routine rather than stressful. Our new students will begin with OETIENT, our orientation course, in order that no one will feel lost on their first day.
Speaking will be taught using the AOA (Accent-Oriented Approach), while our classrooms for teaching are named EPIC (Emotionally Powerful Interactive Classrooms). We also run Rendering Boot, our translation classes for speaking, which help candidates who think in their first language convert ideas smoothly into clear English.
This combination is why healthcare professionals across the region call us the best OET preparation course and the best OET coaching centre. We are also recognized as the best OET centre in Kerala, and our best OET online classes in Kerala offer the same expertise to those who cannot join us physically. No matter where you are, we give you the framework and correction that will raise your score.
Building Real Clinical Communication Skills
Here is something worth remembering. The OET Writing sub-test is not testing your ability to pass a test. It is testing your clinical communication skills in written form. The same skills that get you a Grade B, selecting relevant information, writing clearly for a specific reader, and keeping the right professional tone are the skills you will use every day once you are working.
That is why we teach around the target reader persona in every writing session. You will first consider the identity of the reader and his or her knowledge before writing a single word. The information required by a community nurse is not the same as that needed by a hospital specialist. After you learn how to ask this question, the Content and Genre & Style criteria will be covered on their own accord.
This change in mindset differentiates between successful candidates who have passed their first attempt and those who keep failing. The score follows naturally.
A Simple Practice Routine
In case you wish to progress rapidly, structure your work. Write one complete letter daily under timed conditions and ensure that you strictly follow the time limits of 45 minutes. Always review your work after writing each letter and make sure you assess it according to all six criteria. Make sure that it is corrected by somebody who understands the criteria, as self-assessment alone will not help.
Also, analyze some good model letters and pay attention to their opening, selection of information and closing. Reading good letters trains your instinct for register and structure faster than any rule list.
At Tijus Academy, this routine is built into our programme through Medscriba and our regular mock tests, so you never have to figure it out alone. Every letter you write comes back with feedback tied to the exact criteria the assessors use.
Conclusion
In this case, the OET writing criteria 2026 value nothing more than writing that can be read and acted on by a real healthcare professional. Purpose that is instantly clear. Content that is relevant and accurate. Language that is clean. Structure that flows. Style that fits the reader. Master those six areas and Grade B is well within reach.
You do not need to be a perfect English writer. You need to be a clear, focused, professional one. That is something that you can learn through proper training and constructive criticism. If you are willing to do your preparation, then we will make sure to guide you towards that goal, because we firmly believe that every healthcare professional deserves their path to success.
