OET Writing for Nurses: The Referral Letter Mistakes That Cost the B Grade

Of the four OET sub-tests, nurses most often have to retake the Writing sub-test. Not because their English is poor, but because the task rewards a kind of clinical judgement nobody teaches on the ward: deciding, under time pressure, what a busy colleague needs to know and leaving everything else out. OET writing for nurses is less an English exam than a test of professional communication, and candidates who treat it as the former routinely land at C+ with excellent grammar. This guide covers what the task asks, how to build a referral letter, where marks really disappear, and the OET writing tips that can fix it in three weeks. If you want structured help, our OET coaching in Kochi covers all four sub-tests, with Writing practice marked against the six criteria.

Quick answer (reviewed September 2026): The OET Writing sub-test for nurses is one letter, usually a referral, written from case notes in 45 minutes (5 minutes' reading time plus 40 minutes' writing), at roughly 180 to 200 words. Two assessors mark it against six criteria: Purpose (scored 0 to 3) and Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language (each 0 to 7), scaled to a 0 to 500 result. Grade B is 350. Most regulators require B; the NMC accepts C+ (300) in Writing if the other three sub-tests are B.

What OET Writing for Nurses Actually Asks

You receive case notes for one patient, typically a page of dated entries covering history, presentation, treatment and plan, plus a task line telling you whom to write to and why you write the letter. That is the whole sub-test.

What makes OET writing for nurses hard is that the notes always contain more than the letter needs. Some entries are essential to the reader, some are background, and some are noise included precisely to test whether you can tell the difference. The exam checks whether you can make that call quickly and cleanly, and the marking criteria reward it. Reading and Listening reward comprehension; Writing rewards selection, which is why strong candidates stall here.

The OET Referral Letter: Anatomy of a Letter That Scores

A strong OET referral letter follows a shape assessors recognise immediately, and departing from it costs marks under Organisation and Layout before a sentence is judged. The structure is: an opening that states who the patient is and why you are writing; a short paragraph of relevant background; the current situation and what has been done; and a closing that states exactly what you want the reader to do. Purpose first, request last, nothing in between the reader does need.

What separates a scoring letter from a failing one is usually what it leaves out. A good OET referral letter does not repeat the admission date three times or restate a full history when the reader only needs its consequence. Report a stable test result as "stable" because the reader needs reassurance, not a number. Include social details such as living alone or how often family visits only when they bear on the request. Every sentence in an OET referral letter has to earn its place by helping the reader act.

A common misconception is that an OET referral letter must be long to be thorough. The opposite is true. Around 190 words that cover everything the reader needs score well on Conciseness and Clarity; the same letter padded to 260 words with restated history scores worse.

Case Notes Selection: The Skill That Decides OET Results for Nurses

If there is one thing to take from this post, it is this: case notes selection is where most marks are lost and won. Language errors cost a band or two. Poor case note selection can pull down Content, Conciseness and Clarity, Purpose, and Organisation all at once, because a letter stuffed with irrelevant detail buries its purpose, runs long, and reads like a transcript rather than a referral.

The test is one question asked of every entry: does the person I am writing to need this to act? A community nurse needs the mobility concern and the living situation, not the admitting doctor's name or a normal chest X-ray. A GP reviewing medication needs the drug, dose, reaction and timeline, not the patient's occupation unless it is relevant. Good case notes selection is therefore not about English at all; it is about reading the task line carefully, keeping the reader in mind, and being disciplined enough to omit information that took effort to read.

The Five OET Writing Mistakes That Cost Nurses the B Grade

Working with candidates who have sat the test more than once, the same five errors recur. None is about vocabulary.

1. Copying the case notes into sentences. Converting every clipped clinical line into a sentence produces a chronological data dump, not a letter. The reader has to work out what matters, and Purpose and Conciseness both suffer.

2. Burying the purpose. The reason for writing appears in the fourth paragraph, after a full history. Assessors look for it in the opening; if it is not there, the Purpose criterion is damaged immediately.

3. Including everything to be safe. Leaving nothing out feels professional but is penalised. Irrelevant detail counts against Content, not for it, and pushes the letter over length, hurting Conciseness and Clarity.

4. Wrong register for the reader. Writing to a fellow nurse as formally as to a consultant, or explaining basic terms to a doctor, misjudges Genre and Style. The recipient in the task line sets the register.

5. Time collapsing at the end. Spending 25 minutes on the first two paragraphs and rushing the request means the one thing the reader must know- what you want them to do- is the weakest part of the letter.

Each is a judgement error, not a language error, which is why generic OET writing tips about grammar do not fix them, and why candidates with strong English still miss the OET B grade in Writing while passing the other three sub-tests.

OET Writing Criteria Decoded for Nurses

The six OET writing criteria are public, and understanding them turns "write a good letter" into a checklist. Purpose (0 to 3): does the reader know immediately why you are writing and what you want? Content (0 to 7): is the necessary information present and accurate, and the irrelevant absent? Conciseness and Clarity (0 to 7): is the letter focused, free of repetition and around the expected length? Genre and Style (0 to 7): does it read as professional correspondence in the right register? Organisation and Layout (0 to 7): do the paragraphs follow a logical clinical sequence with a proper opening and close? Language (0 to 7): are grammar, vocabulary, spelling and punctuation accurate enough not to impede the reader?

Two things about the OET writing criteria matter for planning. Four of the six are directly affected by what you choose to include, and only one is purely about language mechanics. And because the scores are combined and scaled to 500, a weak band in Content or Purpose cannot be rescued by flawless grammar. Candidates who read the OET writing criteria properly stop asking "is my English good enough?" and start asking "does this letter do its job?"

OET Writing Tips: What a Three-Week Fix Involves for Nurses

Most OET writing tips online are about grammar, and grammar is rarely the problem. A fix that works has a different shape: a first phase spent purely on selection, sorting practice case notes into what to include and what to omit; a second phase writing to the clock in a fixed four-part structure at the right length; and a third phase adjusting register to the reader, then sitting a full OET mock test with every letter marked criterion by criterion. Above all, the marking matters: without feedback against the six criteria you cannot tell whether your weakness is Content or Language, and the fixes are completely different. That's how our OET preparation course runs, and it is why the OET writing tips that actually move a grade are so hard to apply alone.

If your Speaking result [link to the OET Speaking post] is already strong, the reader-awareness that earned it is exactly what Writing needs; the skill transfers once you apply it to the page.

Frequently Asked Questions About OET Writing for Nurses

What is the OET Writing task for nurses? One professional letter, most often a referral, written from case notes for a single patient in 45 minutes: 5 minutes to read the notes and 40 to write. The letter should be roughly 180 to 200 words, addressed to the reader named in the task line.

How is OET Writing marked? Two trained assessors mark against six criteria: Purpose (0 to 3) and Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language (each 0 to 7). Scores are combined, scaled to 0 to 500, and reported as a grade from A to E. Grade B is 350.

Do nurses need a B in OET Writing? Most regulators require Grade B (350) in all four sub-tests. The NMC is an exception: it accepts C+ (300) in Writing, provided Reading, Listening and Speaking are all Grade B. Confirm the requirement of the regulator you are applying to.

Where do most nurses lose marks in OET Writing? On choosing what to include from the case notes, and on purpose, not on grammar. Letters that include irrelevant detail, bury the reason for writing or run long lose marks across Content, Conciseness and Purpose together.

Is an OET writing sample useful for practice? Yes, if used correctly. Read an OET writing sample for its choices, what it included, omitted and led with, rather than copying its phrases, then attempt the same case notes yourself before comparing. Studying a sample for selection builds the skill; memorising its sentences does not.

The Bottom Line on OET Writing for Nurses

Nurses pass OET writing by writing like nurses: purpose first, only what the reader needs, the request unmistakable at the end. The mistakes that cost the OET a B grade are judgement errors, and judgement can be trained in weeks once you stop treating the test as an English exam and start treating it as a handover in writing.
