IELTS General Training letter: formal, semi formal or informal?

The Task 1 letter looks like the easy part of IELTS General Training. Then the results come back and Writing is the lowest score. Tone is very often the reason.

By Teacher J · Updated September 2026

In IELTS General Training Writing Task 1 you write a letter of at least 150 words in about 20 minutes. The question tells you who you are writing to and gives you three bullet points to cover. Two things decide most of your Task Achievement mark: whether your tone fits the reader, and whether you cover all three bullet points properly.

FormalTo: a company, a strangerDear Sir or Madam,Yours faithfully,No short forms. Semi formalTo: a manager, a landlordDear Mr Adeyemi,Yours sincerely,Polite, clear, direct. InformalTo: a friendDear Tom,Best wishes,Warm, short forms fine.
Your reader decides your tone, your opening and your closing.

Look at the reader first

Look at this

Write to your manager. Ask for two days off next week. Explain why, and say how your work will be covered.

Hey boss! Hope you're good. Need a couple of days off next week, is that cool? Cheers!This is how you might text a friend. To a manager, it sounds rude, and Task Achievement drops.
Dear Mr Adeyemi, I am writing to ask whether I could take two days of leave next Thursday and Friday.Polite, clear and with the purpose in the first line. The tone fits the reader.
Take a look

Write to a friend who has invited you to their wedding. You cannot go.

Dear Sir or Madam, I regret to inform you that I shall be unable to attend the ceremony.Far too cold for a close friend. The wrong tone again, just the other way.
Dear Ama, I am so sorry, but I won't be able to make it to your wedding, and I am honestly gutted.Warm and personal. Short forms like won't are fine here.

Cover all three bullet points

If one bullet point gets one line, or goes missing, your band drops, however good your English is. Give each bullet point its own paragraph, in the same order as the question. It makes your letter easy to follow and easy for the examiner to tick off.

Be yourself in the details

Invent a real sounding reason: a sister's wedding in Accra, a hospital appointment for your son, a leaking kitchen ceiling. Real details make the letter natural, and natural English scores better than a learned model letter that fits nobody.

A letter routine for the exam

  1. Read the task. Who is the reader? Decide formal, semi formal or informal.
  2. Write the purpose of the letter in your first sentence.
  3. One paragraph for each bullet point, in order.
  4. Match your closing to your opening: Dear Sir or Madam with Yours faithfully, Dear Mr Adeyemi with Yours sincerely, Dear Tom with Best wishes.
  5. Stay around 160 to 190 words. Save your time for Task 2.
