What Is the IELTS General Writing Task 1?

Ever wondered what sets this section apart? You’re asked to write a letter of at least 150 words in 20 minutes. It’s the first part of the General Training Writing test, and it assesses your ability to communicate clearly in everyday contexts.

Knowing the basics is half the battle. Task 1 could involve writing to a friend, a company, or an official. Each scenario demands a different tone and level of formality.

(No kidding.)

“Candidates must demonstrate task achievement, coherence, cohesion, lexical resource, and grammatical range.” —British Council

Why Letter Writing Matters in IELTS General Training

Here’s the thing: this letter counts for one-third of your Writing score. Miss the tone by writing an informal note to an employer, and you could lose bands.

Letters test real-world skills—something many IELTS candidates underestimate. You need clear purpose, logical flow, and appropriate style.

Did you know that poor task response can cut your score by up to 2 bands? According to the IELTS scoring criteria, examiners focus heavily on relevance and clarity.

Actionable takeaway: Aim for a clear opening sentence that states your purpose immediately.

Types of Letters: Formal, Semi-formal, Informal

Letters come in three flavors—formal, semi-formal, and informal. Choosing the right one sets the tone.

Context matters: writing to a friend? Keep it casual. Contacting a company? Be polite but not overly stiff.

• Formal: For officials or companies, use “Dear Sir/Madam.”
• Semi-formal: For acquaintances, mix polite language with a personal touch.
• Informal: For friends and family, feel free to be relaxed and friendly.

Real example: If a prompt asks you to complain about noise from neighbors, use a formal tone with clear requests.

“Tailor your style to the reader,” advises Cambridge experts.

Actionable takeaway: Underline or highlight keywords in the prompt to decide formality.

Step-by-Step Letter Structure and Format

Structure is your roadmap to coherence. Without it, your ideas might wander.

1. Opening & Purpose: Greet the reader and state your reason.
2. Body: Develop 2–3 points with examples or details.
3. Closing: Finish politely with a call to action or thanks.

Each section should be 2–4 sentences long. That keeps your letter focused.

Actionable takeaway: Sketch a quick plan (in 1 minute) before writing to save time.

Band 7+ Sample Letters

To see theory in action, let’s review two 150+ word samples.

Informal Letter Sample: Camping Invitation

Dear Lucy,

How have you been? I hope you’re up for an adventure because I’m planning a weekend camping trip at Blue Ridge Park next month. I’d love for you to join—there’ll be hiking, a campfire, and even stargazing if the sky’s clear. The plan is to leave early on Saturday (August 15th) and return by midday Sunday. I can arrange transport from your place if that helps. Let me know what gear you need and if you have any dietary preferences. It’s been ages since we hung out—this is the perfect escape.

Can’t wait to catch up!

Best,

Mike

Formal Letter Sample: Requesting Time Off

Dear Mr. Thompson,

I am writing to request paid leave from September 10th to 14th, 2025, due to a family commitment overseas. I have arranged for my project duties to be covered by Samantha Lee and will ensure all reports are submitted before my departure. Kindly let me know if any further documentation is required. Your approval would be greatly appreciated, as it will help me coordinate travel and lodging in advance.

Thank you for considering my request. I look forward to your positive response.

Sincerely,

Jordan Smith
