Structuring IELTS Academic Task 1 Effectively
The Perfect Paragraph Structure

Clear organisation is essential for Academic Writing Task 1. Here we provide a simple, easy-to-follow introduction to a reliable paragraph structure, helping you get started with confidence.
1. Follow the 4-Paragraph Structure
A clean, professional Task 1 response typically looks like this:
Paragraph 1: Introduction
Paraphrase the question.
Use synonyms and change the grammar where possible.
State the measurements used or/and the time periods.
Examples of introductions:
The chart illustrates the percentage of energy produced from renewable sources in four countries between 2000 and 2020.
The maps demonstrate the changes to the town of Ryedale during 2000 and 2010.
The diagram shows the process of generating electricity in a hydroelectric power station.
Paragraph 2: Overview
This is the most important paragraph in Task 1.
It should summarise the biggest, clearest trends, such as:
overall increases or decreases
the highest/lowest values
key contrasts
major patterns
Do not include specific numbers here.
Examples of overviews:
Graph: It can be clearly seen that all countries experienced an upward trend, with Country A producing the highest proportion of renewable energy by the end of the period.
Map: It is evident that the town underwent significant changes with new housing, a shopping center, and a school added and replacing the smaller townhouses and green spaces.
Process: Overall, the hydroelectric power station generates electricity by using water to drive turbines, which convert kinetic energy into electrical energy in a clear, sequential process.
Paragraph 3: Key Detail Paragraph A
Choose the first group of data to describe.
This could be:
two categories that behave similarly
the highest figures
the earliest years
one side of a comparison
Include numbers, dates, and specific changes.
Example:
Graph: In 2000, Country A produced 15% renewable energy, rising steadily to 35% by 2020.
Map: In the original map, much of the central area was open land, but by 2009 this space was occupied by new residential buildings.
Chart: In 2022, the number of students enrolled in science courses reached 4,500, which was significantly higher than the 3,200 students enrolled in arts courses.
Paragraph 4: Key Detail Paragraph B
Describe the other group of data.
Follow the same style as Paragraph 3 so your writing feels balanced.
Example:
Country B, by contrast, began with only 5% in 2000 but saw rapid growth, reaching 25% in 2020.
2. Keep Your Paragraphs Clean and Focused
Here are the golden rules:
One main idea per paragraph
Do not mix trends
Do not jump back and forth between categories
Use linking phrases lightly (“in contrast”, “similarly”, “meanwhile”)
This creates clarity and boosts your Coherence score.
3. Think in Pairs, Groups, and Patterns
Before writing, spend 20 seconds grouping the data:
Which items rise?
Which items fall?
Which lines follow similar patterns?
Which categories can be compared together?
These groups become your body paragraphs.
4. Use a Simple Formula (Every Time)
If you feel overwhelmed, follow this easy template:
Intro → paraphrase
Overview → 2–3 main trends
Detail Paragraph A → specific data about group 1
Detail Paragraph B → specific data about group 2
This works for:
line graphs
bar charts
pie charts
maps
processes
tables
5. Avoid These Common Mistakes
Writing numbers in the overview
Describing every tiny detail
Mixing categories and confusing the reader
Using overly complex sentences
Comparing categories that don’t belong together
