Level: B2. Task 1 is the shorter of the two IELTS Academic Writing tasks. You are given one piece of visual information and you describe what it shows — clearly, accurately and in your own words. This page explains the format, the marking, a reliable structure and a full sample answer, then points you to the course pages that build the skill.
By the end of this page you can…
…recognise every Task 1 prompt type, plan a four-paragraph answer, use the right language for trends and comparisons, and avoid the mistakes that cost the most marks.
IELTS Academic Writing at a glance
The Writing paper lasts 60 minutes and has two tasks, both of which you must complete (IELTS). Task 1 is the smaller job:
| Feature | Task 1 |
|---|---|
| What you do | Describe a graph, table, chart or diagram in your own words |
| Minimum length | 150 words |
| Suggested time | About 20 minutes |
| Weighting | Counts less than Task 2 toward your Writing band |
| Answer form | Full sentences — never notes or bullet points |
Because Task 2 contributes twice as much as Task 1 to the Writing score (IELTS), spend about 20 minutes here and leave 40 for the essay.
What Task 1 can ask you to describe
In Task 1 you have to describe some visual information — a graph, table, chart or diagram — and all the information you need is in the image itself (IELTS). The common prompt types are:
- Line graph — change over time (describe the trends).
- Bar chart — compare quantities across groups.
- Pie chart — proportions of a whole (percentages).
- Table — numbers you must group and summarise.
- Process diagram — stages of how something is made or works (describe in sequence).
- Map — how a place changed, or two places compared (describe by position).
A line, bar, pie or table is about data. A process or map is about sequence or position, so you do not talk about trends — you describe stages or locations in order.
How the four marking criteria work
A certificated examiner marks each task on four criteria, weighted equally (IELTS):
| Criterion | What it rewards in Task 1 |
|---|---|
| Task achievement | Covering the data accurately, with a clear overview of the main features |
| Coherence and cohesion | Logical order and smooth linking of ideas |
| Lexical resource | A range of accurate, appropriate vocabulary |
| Grammatical range and accuracy | Varied, correct sentence structures |
A simple four-paragraph structure
- Introduction (1 sentence) — paraphrase the prompt: say what the visual shows, where and when.
- Overview (1–2 sentences) — the two or three biggest features, with no specific numbers.
- Detail paragraph 1 — the first group of data, with figures.
- Detail paragraph 2 — the second group, with figures and comparisons.
For a process or map, keep the introduction and overview, then replace the two detail paragraphs with the stages in order (process) or before/after description (map).
Useful language for Task 1
| Job | Language |
|---|---|
| Introduce | The graph shows… / The chart illustrates… / The table gives figures for… |
| Overview | Overall, … / The most striking feature is… / In general, … |
| Rising | rose, increased, climbed, grew — a sharp rise, a steady increase |
| Falling | fell, decreased, declined, dropped — a slight fall, a steep decline |
| No change | remained stable, stayed constant, levelled off |
| Compare | far higher than, roughly double, the same as, slightly below |
| Approximate | about, just over, nearly, around, approximately |
A sample Task 1 answer
This answer gives an introduction, a clear overview, grouped detail with figures, and a closing comparison — the shape examiners look for.
Example sentences
Press play and copy the rhythm. These are the lines you will reuse across almost any Task 1 answer.
- The graph shows the number of visitors to three museums over ten years.A clear introduction that paraphrases the prompt.
- The table gives figures for household spending in four countries.Introducing a table.
- Overall, sales rose steadily across the whole period.An overview sentence stating the big picture.

Quick recap before you practise.
How to say it
A few words in trend language trip up English learners — copy the stress.
- steadily has three beats, stress on the first: STED-i-lee.
- approximately is uh-PROK-si-mit-lee, stress on the second beat.
- considerably is kuhn-SID-er-uh-blee, stress on the second beat.
- figure is FIG-er in British English (the gu is a hard g).
Usage notes
- No opinions. Task 1 is a report. Save phrases like I think for Task 2.
- Tenses follow the dates. Past data takes the past simple; a process diagram with no dates takes the present simple (often passive: the beans are roasted).
- Paraphrase the prompt in your introduction — copying it word for word is not rewarded.
- Round sensibly. Just over 250,000 reads better than a long exact number lifted from the axis.
