IELTS Writing Task 1 (Academic): How to Describe Data for a Higher Band
Academic Task 1 asks you to summarise visual data in 150 words. Here's a structure that works for any chart, plus the trend language and overview sentence examiners look for.
What Academic Task 1 asks for
In Academic Writing Task 1 you have 20 minutes to write at least 150 words describing visual information: a line graph, bar chart, pie chart, table, map, or process diagram. You are not asked for an opinion — only to select and report the main features, and make comparisons where relevant.
It is marked on four criteria: Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
A four-paragraph structure for any visual
- Introduction: paraphrase the question — say what the chart shows, where, and when.
- Overview: the most important paragraph — describe the two to four biggest features or trends, with no specific numbers.
- Body 1: detail and data for the first group of features.
- Body 2: detail and data for the rest, with comparisons.
The overview wins marks
You cannot reach Band 6 without a clear overview. After your introduction, write a sentence beginning Overall, and state the headline message — what is highest, lowest, or the general direction — before giving any numbers.
Most graphs move over time, so you need flexible ways to describe change:
- Rises: increase, grow, climb, surge, rise (sharply / gradually / steadily).
- Falls: decrease, decline, drop, fall, plummet.
- No change: remain stable, level off, plateau, stay constant.
- Vary the form: there was a sharp rise and figures rose sharply say the same thing — use both.
Describing maps and processes
- Maps: use the language of location and change (to the north of, was replaced by, a new… was built).
- Processes: use sequencing (first, next, after that, finally) and usually the passive (the beans are roasted).
- Neither needs numbers — describe the stages or changes in order.
Common Task 1 mistakes
- No overview, or an overview buried in detail.
- Listing every number instead of selecting the main features.
- Giving opinions or reasons (this is because…) — Task 1 is description only.
- Spending more than 20 minutes and stealing time from Task 2.
Once your essay is structured, the fastest way to improve is to write one and get it checked against the descriptors.
