IELTS Academic Writing Task 1
Describing visual information such as a graph, table, chart or diagram.
Five concepts — Academic Writing Task 1 as a report, not an essay. You summarise a graph, chart, table, map or process in at least 150 words in about 20 minutes. Task 2 carries twice the weight, so the skill here is selection, overview and precise description — never opinion.

1Report the visual; do not argue
Academic Writing Task 1 asks you to describe and summarise visual information — a line graph, bar chart, pie chart, table, map or process diagram — in at least 150 words. The recommended time is about 20 minutes so you leave more for Task 2, which examiners weight twice as heavily.
Your job is to report what the visual shows. Do not give opinions, reasons or speculation about why the figures changed. A sentence that starts 'This happened because…' or 'I think…' is Task 2 language and costs Task Achievement here.
Figure. Task 1 is a data report, not an essay of views. Describe selected features; do not explain causes or say whether the trend is good.
| Constraint | What it means |
|---|---|
| Minimum length | At least 150 words |
| Time budget | About 20 minutes (save more for Task 2) |
| Weight vs Task 2 | Task 2 counts twice as much |
| Stance | Report and compare data — no opinion or causal guesswork |
| Input types | Graph, chart, table, map or process diagram |
A Task 1 line graph shows rising smartphone sales. Which sentence belongs in a high-scoring answer?
- Sales rose because people prefer phones to laptops.
- Sales increased from 2 million in 2010 to 8 million in 2020.
- In my opinion, the upward trend is a positive development.
Only the middle option reports a change with data. The first invents a cause the graph does not give; the third adds personal opinion — both break the report-only demand.
2Select key features; do not catalogue every number
A high-scoring answer highlights the main trends or the most significant features and supports them with selected data. Listing every bar, slice or cell reads as a data dump and usually misses the comparison the examiner expects.
Group categories that behave alike, name the highest and lowest, and pick a few figures that prove the claim. The overview names the pattern; the body paragraphs supply the evidence.
Figure. An overview names the main highs, lows and overall change. Cataloguing every plotted number burns words and still misses the picture the examiner wants.
Choose what to report
- Scan the whole visualFind the overall direction, the biggest gap, or the largest share before writing any sentence.
- Group and compareCluster series or categories that rise, fall or stay flat together; contrast them with the odd one out.
- Pick supporting figuresTake two or three numbers that prove each claim — peaks, lows, start/end values — and leave the rest out.
A bar chart compares five countries' recycling rates. The best Task 1 approach is to
- State each country's exact percentage in five separate sentences with no comparison
- Name the highest and lowest rates, group mid-range countries, and quote a few figures
- Explain why the top country recycles more than the others
Selecting extremes, grouping similar mid values and quoting support is the key-features pattern. A full catalogue without comparison is a dump. Explaining 'why' is opinion/cause — outside Task 1.
3Introduction, overview, then detailed body
A clear Task 1 response has three jobs in order: an introduction that paraphrases what the visual shows, an overview that names the main trends or biggest changes without specific numbers, and one or two body paragraphs that support those claims with figures.
Omitting a separate overview caps Task Achievement — examiners look for that big-picture statement. Copying the prompt word for word in the introduction also costs Lexical Resource; paraphrase the subject, units and time span instead.
Figure. Open with a paraphrase, put the big picture in a clear overview, then support it with grouped detail. The overview is the band-critical middle — skip it and the report looks like a list.
Build the four-part skeleton
- IntroductionParaphrase the prompt: what is shown, the units, and the period or places — no data yet.
- OverviewState the most striking pattern or change in general language (overall, the largest share, a sharp rise) with no exact figures.
- Body paragraphsOne or two paragraphs: topic claim first, then selected numbers, comparisons and exceptions.
- Check length and stanceConfirm 150+ words and that no sentence argues a cause or personal view.
Which sentence belongs in the overview paragraph, not the body?
- Consumption rose from 2 kg per person in 2000 to 6 kg in 2020.
- Overall, coffee consumption increased substantially over the period, despite a brief mid-period dip.
- The graph illustrates per-person coffee consumption between 2000 and 2020.
The overview names the main pattern without exact figures. The first option is body detail with numbers. The third is an introduction paraphrase of what the graph shows, not an overview of trends.
4Trend verbs, adverbs and comparisons
Describe change with a range of trend verbs — increased / rose / climbed, fell / declined / dropped, fluctuated, remained stable / plateaued, peaked at, reached a low of — and pair them with adverbs that match the degree: sharply, dramatically, steadily, gradually, slightly.
Comparisons carry as much weight as single-series verbs: compared with, whereas, while, twice as high as, the highest / lowest. Repeating 'went up' in every sentence caps Lexical Resource even when the data are correct.
Figure. One line, three verb choices. The level run from 2010 to 2015 is 'remained stable'; the steep climb after it is 'rose sharply'; the maximum in 2018 is 'peaked'. The slight fall after 2018 is what makes 'peaked' the right verb — a line still climbing at its end 'reached a high', it did not peak. Pick the verb from the shape, then an adverb from the steepness.
| Job | Useful forms |
|---|---|
| Upward change | increase / rise / climb; grow; soar (strong) |
| Downward change | fall / decline / drop; decrease; plunge (strong) |
| No clear direction | fluctuate; remain stable / level off / plateau |
| Extremes | peak at; reach a high / low of |
| Degree (adverb) | sharply / dramatically; steadily / gradually; slightly |
| Compare series | whereas / while; compared with; twice as high as; the highest / lowest |
A line stays almost flat from 2010 to 2015, then jumps to a maximum in 2018. The best body sentence is
- It went up and then went up more.
- After a stable period, the figure rose sharply and peaked in 2018.
- The figure fluctuated wildly throughout the whole period.
Stable then sharp rise to a peak matches the described shape. Vague 'went up' wastes lexis. 'Fluctuated wildly throughout' invents oscillation the stem does not give.
5Process diagrams and maps: sequence and change
Process diagrams are described stage by stage in order, usually in the passive voice with sequencers: first, then, next, after that, finally. The overview names how many main stages there are or what the start and end products are — still without listing every machine.
Map tasks compare two times or propose developments. Describe location with north / south / east / west and what was added, removed or replaced: 'A car park was built to the north of the school.' Keep the same report-only rule — no arguing whether the change is good.
Figure. Process diagrams move stage by stage (first, then, finally), usually in the passive. Map tasks name what was added, removed or replaced with compass directions — still report only, no opinion.
Write a process or map response
- Classify the visualProcess (stages of making/doing) versus map (places changing over time or a proposed plan).
- Overview firstProcess: count main stages or name start→end. Map: name the biggest change or the main new features.
- Sequence the bodyProcess: passive + first / next / after that / finally. Map: relocate features with compass directions and change verbs (was built, was demolished, was converted).
A diagram shows paper recycling: collection → sorting → pulping → cleaning → new paper. The best opening for the first stage is
- First, people should collect used paper from homes and offices.
- First, used paper is collected from homes and offices.
- I would start by collecting paper because recycling matters.
Process Task 1 prefers passive reporting of what happens in the diagram. 'People should' and 'I would… because' add advice or opinion the task does not ask for.
Notes
- The Task: In Academic Writing Task 1 you describe and summarise visual information — a line graph, bar chart, pie chart, table, map, or process diagram — in at least 150 words within about 20 minutes. You must report, not give opinions.
- Select and Report Key Features: A high-scoring answer highlights the main trends or most significant features and supports them with data from the visual. Do not describe every single number; group and compare data logically.
- Structure: A clear response has an introduction (paraphrase the question/what the visual shows), an overview (the main trends/biggest changes with no specific numbers), and one or two body paragraphs with supporting details and figures.
- Language of Trends: Use varied trend vocabulary — 'increased/rose/climbed', 'fell/declined/dropped', 'remained stable/plateaued', 'peaked at', 'reached a low of' — with appropriate adverbs ('sharply', 'gradually', 'slightly').
- Process and Map Tasks: For a process, describe the stages in sequence with passive voice and sequencers ('First, the beans are roasted...'). For maps, describe changes over time using directions and passive structures ('A car park was built to the north').
Formulas
- Task 1 structure: Introduction (paraphrase) → Overview (main trends, no data) → Body 1/2 (details with figures).
- Overview rule: state the biggest/most striking features WITHOUT specific numbers; this paragraph is essential for a good score.
- Trend verbs: rise/increase/climb; fall/decline/drop; fluctuate; level off/remain stable; peak; reach a low.
- Adverb pairing: sharply, dramatically, steadily, gradually, slightly — to describe the degree of change.
- Comparison language: 'compared with', 'whereas', 'while', 'twice as high as', 'the highest/lowest'.
- Process template: use passive + sequencers (first, then, next, after that, finally) to describe stages in order.
Exam traps & shortcuts
- Always include a separate overview paragraph naming the main trends — omitting it caps your band score.
- Do not give opinions or reasons in Task 1; only report and compare what the data shows.
- Paraphrase the prompt in your introduction instead of copying it word for word.
- Spend only ~20 minutes here and save more time for Task 2, which is worth double.
Reference tables
Keep the overview, the time split and the process/map defaults in one place.
| Peg | Rule |
|---|---|
| Structure | Paraphrase intro → overview (no numbers) → body with figures |
| Overview | Biggest trends or stages only — omitting it caps Task Achievement |
| Stance | Report and compare; never opinion or invented causes |
| Time / length | ~20 minutes; 150+ words; Task 2 is worth double |
| Process | Passive + sequencers (first, next, after that, finally) |
| Maps | Compass directions + change verbs (built, demolished, converted) |
Recap
Pin these before you write under the clock.
- Stance
- Task 1 reports the visual — no opinions, reasons or 'I think'.
- Overview
- Separate overview of main trends/stages without exact numbers; skipping it caps Task Achievement.
- Selection
- Highlight key features and compare; do not catalogue every cell.
- Lexis
- Vary trend verbs and degree adverbs; use whereas / while / twice as for comparisons.
- Process / map
- Passive + sequencers for processes; directions + change verbs for maps.
