Bar charts in IELTS Writing Task 1
Practise how to transform a bar chart into an organised response: read categories, identify rankings, group bars and compare differences without describing every item.
The practice includes explained answers for overviews and grouping, plus an annotated Task 1 model response.
Official format versus WeLearn strategy
Official format: IELTS Academic Writing Task 1 asks you to describe visual information. A bar chart belongs to this family of visuals, but we do not present it as a separate official task.
WeLearn strategy: we practise bar charts separately because they reward selective comparison: leaders, lows, large gaps, group patterns and exceptions.
Workflow for a bar chart
Find the rankings
Look for the highest and lowest bars and whether one group dominates several categories.
Group by pattern
Combine similar or contrasting categories; do not follow visual order if it does not help.
Select meaningful gaps
Use figures where the difference matters rather than repeating every value.

Introduction
The bar chart compares the proportions of campus-based and online students who selected five subject areas in 2024.
Why it works: Paraphrase the prompt and make the unit clear: student proportions.
Overview
Overall, campus students showed stronger preferences for Business, Engineering and Health, whereas online learners were more likely to choose Languages and Design. The highest figure was for Business among campus students, while Languages was the leading online subject.
Why it works: Present the main contrast and the leader in each group without overloading the response with figures.
Body 1
Business was the most popular campus subject, at 74%, compared with 52% among online learners. A similar pattern can be seen in Engineering, where the campus figure stood at 68%, substantially above the online figure of 41%.
Why it works: Group two categories with the same pattern: higher campus figures and lower online figures.
Body 2
By contrast, online students were more likely to choose Languages and Design, at 70% and 63% respectively, while the corresponding campus figures were 31% and 46%. Health also favored campus learners, with 58% choosing it compared with only 35% online.
Why it works: Close with the opposite contrast and add Health as supporting evidence rather than the main idea.

Frequently asked questions
Is a bar chart a separate official IELTS Writing Task 1 type?
It should not be presented as an independent official category. IELTS Academic Writing Task 1 asks you to describe visual information such as graphs, tables, maps, diagrams or processes. WeLearn separates bar charts as a practice route because they often require category, ranking and difference comparisons.
What should the overview prioritise in a bar chart?
It should summarise the largest differences: the leading and lowest categories, group contrasts, an overall pattern or a change in ranking. It should not repeat every bar one by one.
How should I organise bar chart body paragraphs?
Group similar or contrasting categories. Instead of describing every bar in visual order, use two paragraphs: one for the main categories and another for secondary groups or exceptions.
