If you want to fail the STANAG 6001 Level 3 writing exam, here’s the fastest way:
Write your “formal letter” like it’s a WhatsApp message.
If you want to pass Level 3, you need to write like someone who belongs in a NATO office, not someone writing to their friend.
This post is a straight-to-the-point guide on how to write a formal letter or formal email in the STANAG 6001 Level 3 exam, what letter types appear most often, and what examiners expect every single time.
Because yes, STANAG writing is predictable.And predictable means easy marks.
STANAG 6001 Level 3 Formal Letters and Emails
What Formal Letter Types Appear in STANAG 6001 Level 3?
Let’s be clear: STANAG Level 3 writing is not creative writing.
You are not here to “express yourself.”You are here to communicate like a professional.
At Level 3, these are the most common formal letter/email types you will see:
Letter of Information
This is the classic “I’m informing you about the plan” type of letter.
Typical topics include training schedules, conferences, exercises, changes in procedures, and official updates. In other words, you’re writing to explain what is happening, when it is happening, and what the reader needs to do.
This letter type is extremely common, and if you can’t write it properly, you will struggle in the exam.
Letter of Advice (Giving and Requesting Advice)
This one shows up constantly because STANAG tasks love planning and coordination.
You may need to request recommendations, suggest improvements, propose solutions, or advise someone about preparations. This task is also perfect for demonstrating formal expressions and indirect questions (which are basically a cheat code for Level 3 writing).
Letter of Invitation (Inviting, Accepting, Refusing)
NATO loves ceremonies, conferences, and official visits, so invitations are a regular feature of the STANAG writing exam.
You may be asked to invite someone, accept an invitation, refuse politely (with reasons), or suggest an alternative opportunity.
And yes, refusing is part of the test. They want to see if you can write diplomatically.
The Brutal Truth About STANAG Level 3 Writing
Most candidates don’t fail because their English is terrible.
They fail because they do stupid things like:
writing one massive paragraph with no structure
forgetting one bullet point from the task
using informal language
writing like it’s a school essay
writing 250+ words and panicking halfway through
STANAG Level 3 is not about being fancy.It’s about being clear, correct, and organised.
How to Write a STANAG 6001 Level 3 Formal Letter (Step-by-Step)
The easiest way to succeed is to follow a repeatable system. You don’t need to reinvent the wheel in the exam. You need a structure you can use every time.
1. Start with a proper greeting
Your letter or email should begin with a formal greeting, such as:
Dear Sir/Madam,Dear Captain Smith,Dear Colonel Jones,
Do not start with “Hi” or “Hello.”This is not social English. It’s official writing.
2. Use an opening sentence that shows purpose
Your first sentence must clearly explain why you are writing. This is where you immediately sound professional.
Strong opening lines include:
I am writing with reference to…
I am writing to confirm the arrangements for…
I am writing to request further information regarding…
I am writing to invite you to…
That opening line is your “uniform.” Put it on immediately.
3. Use the golden rule: 3 task points = 3 paragraphs
This is where most people fail STANAG writing.
The exam instruction usually gives you three bullet points. That means you must write three body paragraphs. No mixing, no chaos.
Paragraph 1 covers point 1.Paragraph 2 covers point 2.Paragraph 3 covers point 3.
Simple structure = clear writing = higher score.
4. Close formally
Your last lines should be short and professional. You don’t need to sound emotional or friendly.
Good closing lines include:
I look forward to your reply.
I would appreciate your response at your earliest convenience.
Please do not hesitate to contact me if further information is required.
5. End with the correct sign-off
This matters more than students think.
Use:
Yours faithfully, (if you started with Dear Sir/Madam)
Yours sincerely, (if you used the person’s name)
Then sign the letter with XYZ.
Paragraph Development:
Stop Writing Like a Shopping List
Level 3 writing is not about listing information. It’s about developing it.
Each paragraph should start with a clear topic sentence and then expand with details, explanation, and reasoning.
Weak example:
The conference is in April. It is in Rome. It starts at 10.
Level 3 example:
The conference is scheduled for mid-April and will take place at our headquarters in Rome. The opening session will begin at 1000 hours and will be followed by presentations and a short discussion period. This schedule has been selected to ensure maximum participation from all units involved.
That is what a Level 3 paragraph looks like.
Linking Words: Use Them, But Don’t Overdose
Linking words make your writing flow and show organisation. You should use them, but you should not sound like a grammar book.
Good linking words for STANAG Level 3 include:
Furthermore, moreover, in addition, however, therefore, as a result, consequently, finally, with regard to, in terms of.
One or two per paragraph is enough.
This is NATO writing, not a TED Talk.
Formal Expressions: The Easiest Way to Sound Like a Professional
If you want to instantly improve your STANAG writing score, stop using casual phrases and start using formal expressions.
Here are the most useful ones:
To give information:
Please be informed that…
I would like to inform you that…
This is to confirm that…
To request information:
I would be grateful if you could provide…
Could you please confirm whether…
I would appreciate clarification regarding…
To give advice:
I strongly recommend that…
It would be advisable to…
I suggest that we consider…
To invite or respond to invitations:
I would like to invite you to…
It would be an honour if you could attend…
Unfortunately, I am unable to accept due to…
However, I would be pleased to participate in…
These phrases are safe, formal, and exactly what STANAG examiners expect.
Formal Language Rules
(Yes, This Can Destroy Your Score)
If you write informally, you will not score Level 3. Simple.
Avoid these common mistakes:
Don’t use contractions:
❌ I’m / we’re / don’t / can’tUse full forms instead.
Avoid informal vocabulary:
❌ stuff, things, a lot, guys
Avoid emotional language:
❌ I’m so excited / I’m really happy / I’m upset
Avoid casual closing lines:
❌ Have a great day / Take care
Your tone should be neutral, professional, and clear.
Indirect Questions: The Level 3 Upgrade Button
Indirect questions make your writing sound formal instantly.
Instead of writing:
What equipment do you need?
Write:Could you please advise what equipment will be required?
Instead of:
How many people can you train?
Write:I would like to know how many trainees you would be able to accommodate.
This is exactly the kind of grammar that pushes your writing into Level 3 territory.
Word Count Strategy (Don’t Be Stupid)
Most tasks say: Write a minimum of 120 words.
That means:
120 words is the minimum.Your safe target is 150–190 words.If you write 250–300 words, you are increasing your chance of mistakes.
More words does not mean a higher level.Clear writing means a higher level.
STANAG 6001 Level 3 Practice Task (Formal Email)
You have been tasked with organising a security conference. You received an email from Captain Jones, one of the speakers, asking for some information. Write an email:
informing him about the date, place and other details of the event
asking for advice concerning equipment or services he might need
suggesting possible accommodation options
Write a minimum of 120 words.
Model Answer (STANAG Level 3 Formal Email)
Dear Captain Jones,
I am writing with reference to your message regarding the upcoming security conference and to provide the requested information.
First of all, the event is scheduled to take place on 18 May at the Defence Training Centre in Verona. The conference will begin at 0930 hours and will include three presentations followed by a short panel discussion. Refreshments will be available during the morning break, and lunch will be provided at the venue.
Furthermore, I would be grateful if you could advise what equipment or technical support you may require as a speaker. In particular, please confirm whether you will need a projector, a screen, laptop connection, or access to printing facilities.
Finally, accommodation can be arranged either at the military guesthouse near the training centre or at a nearby hotel in the city centre, depending on your preference.
I look forward to your reply at your earliest convenience.
Yours sincerely,XYZ
