If you’ve searched online for “the best OET Writing template” or “the exact OET letter format,” you’re not alone.

One of the most common questions OET candidates ask is:

“Can I use the same format for every referral letter?”

The short answer is yes and no.

Yes, every high-scoring OET letter follows a clear framework. It has a logical introduction, well-organised body paragraphs, and a conclusion that clearly states the required action.

However, no single template or paragraph structure works for every writing task.

OET Writing for Nurses: The Exact Letter Format Examiners Want to See

Because every OET letter is written for a different healthcare professional, a different purpose, and a different patient. A community nurse doesn’t need the same information as a physiotherapist. A specialist expects different details from a diabetes educator. If you write every letter using the same structure, you risk including irrelevant information or organising important details in a way that makes the letter harder to read.

This is exactly what the OET Writing sub-test assesses. Examiners aren’t looking for candidates who have memorised a model letter. They’re looking for healthcare professionals who can communicate clearly, select relevant information, and organise it in a way that supports safe and effective patient care.

So, what is the “exact letter format” examiners want to see?

The answer isn’t a rigid template — it’s a reader-focused framework.

In this guide, you’ll learn:

• why memorising one template can limit your score,
• how to choose the most appropriate writing structure for different situations,
• when to use a chronological, logical, or hierarchical approach,
• how to select only the most relevant case notes,
• why grammar choices such as past simple, present perfect, and past perfect matter, and
• how experienced OET writers think before they write.

By the end of this article, you’ll understand that achieving a high score isn’t about finding the “perfect template.” It’s about knowing how to organise information in the format that best serves the reader and the purpose of the letter — the exact skill OET examiners are looking for.

PART 1: Stop Looking for Templates — Start Thinking Like a Healthcare Professional

If I could change one habit among OET Writing candidates, it would be this:

I would stop them from searching for the “perfect template.”

Every week, I receive messages like these:

“Ma’am, can you send me the latest OET template?”
“Which introduction should I memorise?”
“Can I use the same body paragraphs for every referral letter?”

I understand where these questions come from. When you’re preparing for an important exam, having a template feels safe. It feels like one less thing to worry about.

Unfortunately, it’s also one of the biggest reasons candidates struggle to improve.

After teaching OET Writing for years, I’ve noticed that students who depend on memorised templates often hit a ceiling. They may write acceptable letters, but when the case notes change — or the reader changes — they don’t know how to adapt.

That’s because OET isn’t assessing your ability to reproduce a template. It’s assessing your ability to communicate professionally.

And professional communication is never one-size-fits-all.

Think About Your Workplace

Imagine you’re working in a hospital.

At the end of your shift, you need to hand over one patient to a community nurse.

Would you follow a memorised script?

Probably not.

Before speaking, your mind automatically asks questions like:

• Who am I handing this patient over to?
• What do they already know?
• What information do they need from me?
• What can I safely leave out?

You don’t realise it, but you’re already following a framework.

That is exactly how successful OET candidates approach the Writing sub-test.

They don’t memorise letters.
They make decisions.

OET Writing Is a Clinical Skill

Many students think OET Writing is mainly a language test.

In reality, it’s just as much a communication test.

The examiner isn’t looking for long sentences or impressive vocabulary. They’re looking for evidence that you can organise information in a way that helps another healthcare professional continue patient care safely.

Think about the letters you read at work. The best ones aren’t necessarily the longest. They’re the easiest to follow.

Within a few seconds, you understand:

• Why the patient has been referred.
• What’s happened so far.
• What action is expected from you.

That’s good professional writing. And that’s exactly what OET rewards.

If you’re wondering how this differs from other English exams, read our detailed breakdown: OET vs IELTS vs PTE: Key Differences Explained.

Frameworks Give You Flexibility. Templates Don’t.

Let’s clear up a common misunderstanding.

When I say, “Don’t memorise templates,” I’m not saying that every letter should be written differently.

In fact, every effective OET letter follows a clear framework.

The difference is that a framework helps you think, whereas a template tells you what to write — even when it doesn’t fit the situation.

Think of it this way.

A template says: Write Paragraph 1 about medical history.

A framework asks: Does the reader actually need the patient’s medical history?

Those are very different approaches. Sometimes the answer will be yes. Sometimes it will be no. The decision depends entirely on the purpose of the letter.

Every OET Letter Begins with Three Questions

Before writing a single sentence, I encourage my students to pause and answer three questions. They seem simple. But together, they determine almost every writing decision you’ll make.

1. Who is the reader?

This question is more important than many candidates realise.

A community nurse, a physiotherapist, a dietitian, a surgeon, and a general practitioner all need different information.

Imagine you’re referring a patient to a physiotherapist following a total knee replacement. Would the physiotherapist need to know that the patient’s childhood immunisations are up to date? Of course not. Would they benefit from knowing the patient’s current mobility, pain level, weight-bearing status, and rehabilitation goals? Absolutely.

The reader determines the relevance of your information.

2. Why are you writing?

Every OET letter has a purpose. You might be requesting:

• further assessment
• ongoing management
• rehabilitation
• home nursing
• community support
• follow-up care

Everything you include should support that purpose.

For example, if you’re writing to a diabetes educator, your reader is primarily interested in information that affects diabetes management. Including five lines about a successfully treated ankle sprain from two years ago only distracts from the main message.

Purpose drives content.

3. What does the reader need to know?

This is probably the question that separates high-scoring candidates from everyone else.

Notice what the question isn’t. It isn’t: “What information is written in the case notes?”

Instead, it’s: “What information does the next healthcare professional need in order to care for this patient?”

That’s a subtle but important shift. You’re no longer copying information. You’re selecting it. And selection is one of the most important professional communication skills in healthcare.

Not Every Case Note Belongs in Your Letter

This is something I say repeatedly during my classes:

Case notes are written for you. The letter is written for the reader.

Those are two completely different documents. The case notes contain everything that happened. Your job is to decide what matters now.

Let’s look at a simple example. Imagine you’re writing to a community nurse requesting wound care after discharge. The case notes include:

• Hypertension diagnosed eight years ago
• Appendicectomy in 2010
• Seasonal allergic rhinitis
• Current wound following abdominal surgery
• Daily dressing requirements
• Signs of mild infection
• Mobility limitations after surgery

Should every detail appear in your letter? No.

The community nurse’s immediate priority is managing the wound safely. That means information about the wound, mobility, pain management, medications affecting healing, and follow-up care is likely to be relevant. An appendicectomy performed many years ago probably isn’t.

Including irrelevant information doesn’t demonstrate thoroughness. It makes the letter harder to read.

Good writing isn’t about including everything. It’s about including the right things.

Part 2: The Three Writing Structures Every OET Nurse Should Know

If you’ve attended one of my writing classes, you’ve probably heard me say this:

“Don’t ask, ‘Which template should I use?’ Ask, ‘How can I make this easier for my reader?'”

That one question changes everything.

Many candidates assume there’s a single “correct” way to organise an OET letter. So they write every referral, discharge, or transfer letter using exactly the same paragraph structure.

However, patients aren’t all the same. Neither are healthcare professionals. A physiotherapist doesn’t read information the same way a community nurse does. A cardiologist isn’t looking for the same details as a dietitian.

So why would every OET letter follow the same structure? It shouldn’t.

Instead of relying on one template, learn to recognise the three organisational frameworks that professional healthcare writers use. Once you understand the purpose behind each one, choosing the right structure becomes surprisingly straightforward.

Understanding these structures is also closely linked to the broader challenge of OET Writing for Nurses: Why Good English Alone Won’t Get You a High Score.

1. Chronological Structure – When the Journey Matters

Let’s start with the structure students usually find the easiest.

A chronological structure tells the patient’s story in the order events happened. Think of it as walking the reader through the patient’s journey — from the first presentation to the current situation.

This approach works particularly well when the progression of symptoms or treatment is the reason for the referral.

Consider this scenario. A patient visits your clinic three times over two weeks.

• During the first visit, she reports mild lower back pain after lifting a heavy box. She is advised to rest and take analgesics.
• Four days later, the pain becomes more severe and starts radiating down her left leg.
• Three days after that, she develops numbness in her foot and difficulty walking.

Now you’re referring her to an orthopaedic specialist. Would it make sense to describe the current symptoms first and then jump back to the first visit? Probably not. The specialist needs to understand how the condition evolved. In this situation, a chronological structure paints the clearest clinical picture.

Your paragraphs might naturally move from:

• Initial presentation
• Subsequent deterioration
• Current condition and reason for referral

Notice what’s happening here. You’re not organising information because “that’s the template.” You’re organising it because the sequence of events explains the patient’s condition.

Why Examiners Appreciate This Structure

A chronological approach helps the reader answer an important clinical question: “How did we get here?”

When a patient’s condition has changed over time, the order of events often influences clinical decision-making. By presenting those events logically, you’re helping the receiving healthcare professional understand not only what happened but also how and when it happened. That’s effective professional communication.

When NOT to Use a Chronological Structure

Here’s where many candidates lose marks. They assume every OET letter should read like a timeline.

But not every referral depends on the patient’s journey. Imagine you’re referring a patient to a community nurse for wound management after discharge. Does the community nurse need a day-by-day account of the patient’s hospital stay? Usually not.

They’re far more interested in questions like:

• What is the wound like now?
• How often should the dressing be changed?
• Are there any signs of infection?
• What follow-up care is required?

A strict timeline would only delay the information they actually need. And that’s where another structure becomes more appropriate.

2. Logical Structure – When Related Information Belongs Together

This is probably the structure I recommend most often. Why? Because healthcare professionals don’t usually think in timelines. They think in categories.

When you receive a referral, you naturally begin grouping information in your mind: current diagnosis, relevant medical history, treatment provided, current status, recommendations.

That’s exactly what a logical structure does. Instead of following the order in which events occurred, it groups related information together so the reader can find what they need quickly.

Let’s Look at an Example

Imagine you’re writing to a diabetes educator. Your patient:

• was admitted with poorly controlled blood glucose levels,
• received insulin stabilisation,
• has a history of hypertension,
• struggles with medication adherence,
• requires dietary education before discharge.

Would the diabetes educator benefit from reading everything in the exact order it happened during admission? Not really.

A more useful structure might be:

Paragraph 1: Purpose of referral and current diabetic status.
Paragraph 2: Relevant medical history and treatment during admission.
Paragraph 3: Education provided, ongoing concerns, and support required after discharge.

The information is grouped according to its purpose rather than its timing. That makes the letter much easier to navigate.

Why This Structure Works

Healthcare professionals are busy. They don’t read referral letters like novels. They scan. They look for key information. A logical structure allows them to locate that information quickly.

One of my favourite questions to ask students is this:

“If your reader only had thirty seconds to read your letter, would they still understand what they need to do?”

If the answer is yes, you’ve probably organised your letter well.

3. Hierarchical Structure – When One Piece of Information Is More Important Than Everything Else

This is the structure students use least often — but it’s incredibly powerful.

A hierarchical structure places the most clinically significant information first, followed by supporting details. In other words, importance determines the order — not time.

Imagine This Situation

A patient has recently undergone bowel surgery. During discharge planning, you notice increasing redness around the surgical wound, purulent discharge, and a low-grade fever. You’re referring the patient to a community nurse for urgent wound management.

Should your first paragraph begin with the patient’s admission date? Probably not. The reader’s immediate concern is the wound. Everything else supports that priority.

A hierarchical structure allows you to begin with what matters most:

• current wound status,
• signs of infection,
• immediate care required,

before discussing the background that explains how the patient reached this point. You’re helping the reader prioritise — exactly as they would in clinical practice.

Why This Structure Is So Effective

Think about clinical handover. When something urgent happens, healthcare professionals don’t usually begin with background history. They begin with the immediate concern. Only then do they provide supporting information.

The same principle applies in writing. By leading with the highest-priority information, you’re directing the reader’s attention exactly where it needs to be. That’s good communication.

So… Which Structure Should You Choose?

This is the question I hear most often. The answer is surprisingly simple.

Don’t choose the structure based on habit. Choose it based on what will help your reader understand the patient’s situation most efficiently.

Ask yourself:

• Does the progression of events explain the condition?
  → Consider a chronological structure.
• Does the reader need information grouped into clear clinical categories?
  → A logical structure will probably work best.
• Is there one urgent issue that should immediately capture the reader’s attention?
  → A hierarchical structure is likely to be the strongest choice.

Notice that none of these decisions are based on a template. They’re based on professional judgement.

A Final Thought Before We Move On

Students often tell me, “Ma’am, I wish there were just one format for every OET letter.”

I understand why they feel that way. But imagine if every healthcare professional communicated using exactly the same format, regardless of the patient or situation. Important information would be buried. Readers would have to work harder. Patient care could suffer.

Good writing isn’t about following rules blindly. It’s about making thoughtful decisions that help another healthcare professional deliver safe, effective care. And that’s exactly what OET is assessing.

Many candidates experience anxiety around these decisions. If that sounds familiar, our guide on Overcoming English Language Anxiety: A Guide for Healthcare Professionals may help.

Part 3: Grammar Isn’t About Rules — It’s About Communicating Clearly

When students ask me how to improve their grammar for OET Writing, they often expect a list of tenses to memorise or grammar exercises to complete.

My answer usually surprises them.

Grammar is not the starting point.

Before you decide which tense to use or whether to write a simple or complex sentence, you need to understand what you’re trying to communicate.

In healthcare, grammar isn’t just about accuracy. It’s about helping another healthcare professional understand the patient’s story quickly and correctly. Every tense, every sentence structure, and every linking word should make your message easier to follow.

Let’s look at how this works in practice.

Choosing the Right Tense: Tell the Story as It Happened

One of the most common questions I hear is: “Should I use the past tense or the present perfect?”

There isn’t one correct answer. The tense depends entirely on the relationship between the event and the time you’re writing the letter.

Think about the patient’s journey. Some events are complete. Some began in the past but are still affecting the patient today. Some happened before another past event. Your tense should reflect those relationships.

When the Past Simple Works Best

The past simple is used for events that happened at a specific time and are now complete. These are facts in the patient’s history.

For example, imagine you’re writing to a respiratory physician. You might write:

Mrs Sharma attended the emergency department three days ago with worsening shortness of breath and a productive cough.

The consultation happened. It ended. The event is complete. The past simple tells the reader exactly that.

Similarly:

She received intravenous antibiotics and oxygen therapy.

The treatment has already been given. There’s no need to suggest it’s continuing.

When the Present Perfect Adds More Meaning

Sometimes the patient’s condition hasn’t simply happened — it continues to influence the present. This is where the present perfect becomes useful.

Imagine a patient who is being referred to a neurologist. Instead of writing:

Mr Ali experienced intermittent dizziness.

consider:

Mr Ali has experienced intermittent dizziness over the past six weeks.

Why is this better? Because the dizziness is still relevant today. The symptoms haven’t become part of history. They’re part of the reason for the referral. The present perfect naturally connects the past with the present.

Taking It One Step Further: Present Perfect Continuous

Sometimes you want to emphasise duration, not just continuation.

Mrs Patel has been requiring daily wound dressing since discharge.

The focus isn’t simply that dressings occurred. It’s that they have continued over a period of time and remain necessary. The present perfect continuous helps highlight continuity. It often appears when describing symptoms, treatments, or care that started earlier and continue up to the present.

For example:

• The patient has been experiencing increasing fatigue.
• She has been receiving community nursing support.
• He has been mobilising with a walking frame.

Notice that each example describes an action or condition that began in the past and is still true when the letter is written.

What About the Past Perfect?

This tense often intimidates students. It doesn’t need to.

The past perfect simply helps us explain which event happened first when both events are already in the past.

Imagine this situation. A patient developed dizziness after starting a new medication. When writing about it, you might explain:

Before attending the clinic, the patient had noticed increasing dizziness for several days.

Here, the dizziness began before the clinic visit. The past perfect helps establish that sequence. You won’t use this tense frequently in every OET letter, but when you’re describing events that occurred before another past event, it helps avoid confusion.

Grammar Should Match the Reader’s Needs

Students sometimes ask me, “Which tense scores the highest?”

The question itself is the problem. Examiners aren’t looking for sophisticated grammar. They’re looking for appropriate grammar.

If a patient’s symptoms are ongoing, choose a tense that reflects that. If treatment has finished, show that clearly. If one event happened before another, make the sequence obvious.

Good grammar isn’t about sounding advanced. It’s about preventing misunderstanding.

Choosing the Right Sentence Structure

Grammar isn’t only about tenses. Sentence structure plays an equally important role.

One mistake I often see is students trying to make every sentence long and complex because they think longer sentences sound more professional. In reality, professional healthcare writing values clarity above everything else.

As Albert Einstein famously said, “The definition of genius is taking the complex and making it simple.” That idea applies beautifully to OET Writing.

Simple Sentences: Best for Important Information

A simple sentence communicates one complete idea. Some students worry that simple sentences sound “basic.” I disagree. Simple sentences are often the strongest choice when introducing new or important information.

For example:

Mrs Thomas requires daily wound assessment.

There’s nothing complicated here. The message is immediate. The reader understands the priority without unnecessary words. Whenever the information is important, clarity should come first.

Compound Sentences: Connecting Equal Ideas

Sometimes two related ideas deserve equal importance. A compound sentence allows you to connect them smoothly.

The wound is healing well, and the patient is managing her pain effectively.

Both pieces of information matter equally. Joining them creates a smoother flow than writing two short, disconnected sentences. Words like and, but, so, and yet can help you connect related ideas naturally.

Complex Sentences: Showing Relationships

This is where many students become overambitious. A complex sentence isn’t better because it’s longer. It’s useful because it explains the relationship between ideas.

As the patient’s mobility remains limited, home physiotherapy has been recommended.

The reader immediately understands why physiotherapy is necessary. The first clause provides the reason. The second explains the action.

Complex sentences are particularly useful when showing:

• cause and effect
• contrast
• condition
• time
• purpose

But here’s an important point. If every sentence becomes complex, your letter quickly becomes difficult to read. Good writers vary their sentence structures. They know when to keep things simple and when a more detailed explanation is helpful.

Don’t Write to Impress. Write to Express.

Some candidates believe impressive vocabulary and complicated grammar will earn higher marks. Unfortunately, the opposite often happens.

Consider these two sentences:

The patient has demonstrated suboptimal adherence to the prescribed pharmacological regimen.

Now compare it with:

The patient has not been taking her medication regularly.

Both communicate the same idea. The second is clearer, more direct, and far easier to read. Professional writing isn’t about using the longest words. It’s about choosing the clearest ones.

As healthcare professionals, our responsibility is to communicate information accurately — not to impress the reader.

Part 4: Bringing It All Together – How to Think Like an OET Writer

By now, you’ve probably realised something important.

Success in OET Writing doesn’t come from memorising introductions, collecting templates, or learning complicated vocabulary. It comes from making good decisions.

Every strong letter is the result of a series of professional decisions:

• Who am I writing to?
• Why am I writing?
• What information is relevant?
• How should I organise it?
• Which grammar best reflects the patient’s situation?
• How can I make this easier for the reader?

When students begin thinking this way, their writing changes dramatically.

Editing Like an OET Examiner

Many candidates spend almost all their time writing. Very few spend enough time reviewing. That’s unfortunate because some of the easiest marks to gain come during proofreading.

The key is knowing what to look for. Instead of reading your letter from beginning to end and hoping to spot mistakes, review it in stages.

Step 1: Check the Purpose

Ask yourself: If someone only read my first paragraph, would they immediately know why I’m writing?

Your purpose should never be hidden. It should be obvious within the opening sentences. If the reader has to search for it, revise the introduction.

Step 2: Check Relevance

Now read the letter again. This time, ask a different question: Does every sentence help the receiving healthcare professional?

If a sentence doesn’t influence future care, reconsider whether it belongs in the letter. One unnecessary paragraph can distract the reader from the information that actually matters.

Remember: Professional writing isn’t about including everything. It’s about selecting wisely.

Step 3: Check Organisation

Now ignore grammar completely. Look only at the order of your ideas. Ask yourself:

• Have I grouped similar information together?
• Does each paragraph focus on one main idea?
• Does the information flow naturally?

Imagine the receiving healthcare professional reading your letter during a busy clinic. Would they have to read a paragraph twice? Or could they quickly understand the patient’s situation? That’s your goal.

Step 4: Check Language

Only after you’ve reviewed purpose, relevance, and organisation should you begin looking at grammar.

As you proofread, ask yourself:

• Is the tense appropriate?
• Have I used patient-friendly and professional language?
• Are my sentences clear?
• Could any sentence be simplified without changing the meaning?

Sometimes replacing one complicated sentence with two shorter ones improves the letter immediately. Clarity should always come before complexity.

The Most Common Mistakes I See in OET Writing

After reviewing hundreds of OET letters, I’ve noticed that the same patterns appear again and again. Interestingly, they rarely have anything to do with advanced grammar. Instead, they involve decision-making.

Trying to include every case note

Candidates often believe that leaving out information means losing marks. In reality, the opposite is usually true. The assessment criteria reward your ability to select relevant information — not reproduce every detail from the notes.

Organising information exactly as it appears in the case notes

The case notes are your source of information. They are not the structure of your letter. Your job is to reorganise that information in a way that helps the reader.

Choosing vocabulary instead of clarity

Some students replace simple healthcare language with long, unfamiliar expressions because they think sophisticated vocabulary creates a better impression. Professional communication isn’t measured by how difficult your words are. It’s measured by how clearly your message is understood.

Writing long paragraphs

Large blocks of text can make even well-written letters difficult to follow. Each paragraph should develop one main idea. This helps the reader locate information quickly and improves the overall flow of the letter.

Forgetting the Reader

This is probably the biggest mistake of all. Some letters sound as though they were written for the examiner. They should be written for the receiving healthcare professional.

Whenever you’re unsure whether to include a piece of information, ask yourself: Will this help the reader provide better care? If the answer is no, it probably doesn’t belong in the letter.

Final Thoughts

Students often ask me, “What’s the secret to getting a high score in OET Writing?”

They’re usually expecting me to mention grammar, vocabulary, or a particular template. My answer is much simpler.

Think like the healthcare professional receiving the letter.

The examiner isn’t looking for someone who has memorised model answers. They’re looking for someone who can communicate safely, professionally, and purposefully.

When you focus on the reader, your writing naturally becomes clearer. When you focus on relevance, unnecessary information disappears. When you organise your ideas thoughtfully, the letter becomes easier to follow. And when you stop trying to impress the examiner and start helping the reader, your writing begins to reflect what OET is really assessing — effective professional communication.

So, the next time you sit down to write an OET referral letter, don’t ask yourself, “Which template should I use?”

Instead, ask: “If I were handing over this patient to a colleague, what would they genuinely need to know?”

That’s the question that transforms an average OET letter into an excellent one.

A Challenge for You

The next time you practise an OET Writing task, don’t write just one letter. Write two versions of the same case.

First, organise the information chronologically. Then rewrite the same letter using a logical or hierarchical structure. Compare the two.

Ask yourself:

• Which version is easier to follow?
• Which one helps the reader find important information more quickly?
• Which structure best suits the purpose of the referral?

This simple exercise develops one of the most valuable skills in OET Writing: professional judgement.

Because ultimately, OET isn’t testing whether you can memorise a template. It’s testing whether you can think like a healthcare professional and communicate in a way that supports safe, effective patient care.
