IELTS Writing Task 1 Guide: Academic Charts and General Training Letters

IELTS Writing Task 1 checks whether you can summarise and compare information clearly. In Academic IELTS, this means describing visual data. In General Training, this means writing a letter for a specific situation.

Academic Task 1 diagram types (with examples)

In Academic Task 1, you should focus on the most important trends, comparisons, and overall patterns. Do not try to describe every single number.

1) Bar chart

Bar charts compare categories. In your response, group similar values and highlight the biggest differences.

2) Line graph

Line graphs show change over time. Focus on trends such as growth, decline, fluctuation, and stability.

3) Pie chart

Pie charts show proportions. Compare the largest and smallest segments and note key shifts between years.

4) Table

Tables provide detailed figures across categories and time. Select key comparisons instead of listing all data points.

General Training Task 1 question types

General Training Task 1 asks you to write a letter. There are three common letter types:

• Formal letter: usually to a company, manager, or institution.
  • Example: “You recently bought a product online, but it arrived damaged. Write a letter to the company.”
• Semi-formal letter: usually to someone you know in an official context.
  • Example: “Your teacher is leaving your school. Write a letter thanking them and describing what you learned.”
• Informal letter: usually to a friend or family member.
  • Example: “A friend will visit your city. Write a letter suggesting places to stay and things to do.”

Word count

• The minimum is 150 words.
• If you write fewer than 150 words, your score can drop.
• A safe target for most candidates is around 165-190 words.
