Academic · all seven visual types
IELTS Writing Task 1
Short answer: Academic Task 1 asks you to report and summarise a visual in at least 150 words in about 20 minutes. The method is identical for all seven visual types — paraphrase, overview, two grouped body paragraphs — and only the tense and voice change with the type.
The seven types
Every Task 1 visual, and the decision each one forces
The structure never changes. What changes is the grammar the visual demands — and that is where bands are won and lost.
| Visual type | What it shows | What it decides | Frequency |
|---|---|---|---|
| Line graph | One or more values changing over time | Tense follows the dates; group time periods rather than listing every point | Very common |
| Bar chart | Values compared across categories, sometimes over time too | Comparison language. A chart described category by category with no comparison caps Task Achievement | Very common |
| Pie chart | Proportions of a whole, often two charts at two dates | Proportion and fraction paraphrase; select the largest shifts instead of reciting every slice | Common |
| Table | Raw numbers in a grid, usually more data than you can report | Selection. Row-versus-column grouping is the whole skill; reciting the grid is the classic failure | Common |
| Process diagram | How something is made, or how a system or natural cycle works | Present simple passive plus sequencers. No numbers means no trends — stages instead | Less common |
| Map | One place at two different times, or a proposed redevelopment | Passive voice, with the tense chosen from the dates on each map | Less common |
| Mixed / multiple charts | Two visuals of different kinds in one question | One overview covering both, then a body paragraph each — not two separate reports | Common |
The method
Six steps that work for every visual type
- 1
Read the question, not the picture
Identify what is measured, in what units, over what period, and for whom. Half of all Task 1 errors are misread axes rather than weak English.
- 2
Paraphrase the question as your introduction
One sentence, your own words, no numbers. Copying the prompt verbatim earns nothing — copied text is discounted from your word count.
- 3
Write the overview before the detail
Two sentences naming the biggest features: highest and lowest, the overall direction, or the first and last stage of a process. Without an overview your Task Achievement is capped no matter how accurate the rest is.
- 4
Group the data into two body paragraphs
Group by trend, by category or by time period — never one sentence per data point. Grouping is what separates a band 7 report from a band 6 list.
- 5
Support with selected figures, not all of them
Quote a number when it anchors a comparison. A report that includes every figure has selected nothing, which is a Task Achievement problem, not a length one.
- 6
Check the four fixed rules
At least 150 words, about 20 minutes, no opinion, and no invented explanation for what the visual shows. Task 1 is one-third of your Writing band; Task 2 is the other two-thirds.

IELTS Writing Task 1 — common questions
How many visual types can appear in IELTS Writing Task 1?
Seven: line graph, bar chart, pie chart, table, process diagram, map, and a mixed question combining two of them. Line graphs and bar charts are by far the most frequent; process diagrams and maps are the ones candidates are least prepared for.
How long should an IELTS Task 1 answer be?
At least 150 words, written in about 20 minutes. Going under 150 is penalised directly under Task Achievement. Going over is not penalised, but longer reports leak accuracy marks and steal time from Task 2, which is worth twice as much.
Do I need an overview in every Task 1 answer?
Yes, for every visual type. A clear overview naming the main features is what a strong Task Achievement score requires; without one the criterion is capped regardless of how precise your sentences are.
Should I explain why the data changed in Task 1?
No. You report and summarise what the visual shows. Speculating about causes, or saying whether a change is good or bad, is outside the task and costs you under Task Achievement. Opinions belong in Task 2.
Which tense should I use in Task 1?
The dates decide it. Past dates take the past simple; a past-to-present range takes the past simple with the present perfect; future projections take will or is expected to. Process diagrams are the exception — they take the present simple passive because they describe a repeating general truth.
Is Task 1 or Task 2 more important?
Task 2, by a factor of two: your Writing band is (Task 1 + 2 × Task 2) ÷ 3. Task 1 is still worth a third, and it is the more learnable of the two because its method is fixed.
