Quick answer
What is IELTS Academic Writing Task 1?
Academic Writing Task 1 asks you to describe, summarise or explain visual information such as a graph, chart, table, process or map. Write at least 150 words in about 20 minutes. A reliable response normally uses four paragraphs: introduction, overview, details paragraph 1 and details paragraph 2.
- Select and compare the main features instead of reporting every number.
- Write a clear overview; do not replace it with a personal conclusion.
- Use an academic or neutral tone and write in connected paragraphs.
- Task 2 contributes twice as much as Task 1 to the Writing score, so control your time.
These test facts follow the official IELTS Academic Writing format.

Explore the IELTS courseThe core method
IELTS Writing Task 1 structure: four paragraphs that work
The structure stays broadly consistent across charts, tables, maps and processes. What changes is the language and the way you group the information.
Introduction
Paraphrase what the visual shows. Include the subject, place, units and time period when relevant. Do not copy the question word for word.
Useful pattern: “The chart compares…”, “The diagrams illustrate…” or “The table presents information about…”
Overview
Summarise two to four dominant features without listing many figures. For data tasks, identify major trends, highest or lowest categories and striking similarities or differences. For processes and maps, describe the overall stages or transformation.
Details paragraph 1
Group related features and support them with accurate figures, stages or locations. Compare information where the task allows it.
Details paragraph 2
Cover the second logical group. Maintain the same units, tense and comparison basis. Check that the details support the overview.
Choose the right method
IELTS Academic Writing Task 1 question types
Use this page for the broad method, then open the specialist guide for the task in front of you. This avoids trying to use trend language for a map or process.
Bar chart
Rank categories, compare groups and identify large or small differences. Confirm whether the chart shows one time point or change over time.
Line graph
Group similar trends and describe rises, falls, fluctuations, peaks and stable periods using the correct tense.
Pie chart
Compare proportions, rank segments and convert percentages into accurate language such as a quarter, a third or the majority.
Table
Find patterns across rows and columns. Group the information instead of describing the table cell by cell.
Process or flow chart
State whether the process is linear or cyclical, identify the main stages and use sequencing and passive forms where natural.
Map or plan
Describe the overall transformation, then group changes by location, time period or type of development.
Mixed or multiple charts
Find the relationship between the visuals, use one overview for the combined task and balance the amount of detail given to each source.
Before you write
How to analyse an IELTS Task 1 visual in two minutes
1. Read the task precisely
Underline the subject, units, categories and time period. Check whether the figures are numbers, percentages, money, distance or another unit.
2. Identify the task family
Ask whether you are reporting data, change over time, a process or a spatial transformation. This determines your comparisons, tense and vocabulary.
3. Circle the dominant features
Find the highest and lowest values, overall direction, biggest changes, unusual exceptions and clear similarities.
4. Create two logical groups
Group by trend, category, time, stage or location. These groups become your two details paragraphs.
For deeper practice, use the guide to identifying key features and trends and the lesson on how to compare and contrast Task 1 data.
The paragraph that controls the report
How to write a clear Task 1 overview
An overview tells the reader what matters most. It should be broader than the details paragraphs and should not become a list of figures.
Include
- The overall rise, fall, fluctuation or stability.
- The leading and lowest categories.
- The most noticeable comparison or exception.
- The number and general direction of process stages.
- The dominant transformation shown by maps.
Avoid
- Every value from the chart.
- Reasons that are not shown in the visual.
- Your opinion about whether a trend is good or bad.
- Memorised sentences that do not fit the task.
- A vague statement such as “many changes can be seen”.
Overview sentence patterns
Data: “Overall, X recorded the highest values throughout the period, while Y remained the lowest.”
Change: “Overall, all three categories increased, although the rise in X was considerably more pronounced.”
Process: “Overall, the linear process consists of six stages, beginning with X and ending when Y is produced.”
Map: “Overall, the area became more residential and accessible, while much of the original open land disappeared.”
Worked example
IELTS Writing Task 1 bar-chart sample with paragraph notes
The example below uses an existing Benchmark practice chart and demonstrates one clear four-paragraph response. The report has not been presented as an officially awarded IELTS band.
Introduction
The bar chart compares the percentages of international graduates at six universities in the United Kingdom in 2000 and 2015.
Why it works: The sentence paraphrases the subject, location, unit and two time points without adding an opinion.
Overview
Overall, Cambridge and Oxford recorded the highest proportions in 2000, while Oxford and Cambridge remained the two leading universities in 2015. All six institutions experienced increases, with London showing the largest rise.
Why it works: It identifies the leading and lowest groups and the dominant direction without crowding the overview with figures.
Details paragraph 1
In 2000, Cambridge and Oxford led the group, with international graduates accounting for approximately 15% and 14% respectively. Cardiff followed at 10%, while Bath and Bristol recorded about 7% and 6%. London had the lowest proportion, at roughly 5%.
Why it works: The figures are grouped by rank, and comparative language makes the relationship clear.
Details paragraph 2
By 2015, Oxford’s figure had risen to 25%, and Cambridge remained close behind at around 23%. London climbed fourfold to 20%, overtaking Cardiff, which increased to approximately 14%. Bath reached about 12%, whereas Bristol remained the lowest-ranked university despite a modest rise to roughly 8%. As a result, the gap between the highest and lowest figures widened from about 10 to 17 percentage points.
Why it works: The second paragraph reports the later year, highlights change and closes with a comparison supported by the data.

IELTS Writing Task 1 examples for every major visual type
Each report below was written directly from an existing Benchmark practice visual. Read the task first, plan your own response, and then compare how the sample selects and groups the information.
Complete line-graph example
Visitors to Cardiff and Dublin, 2018–2040
Approach
- Separate the overall direction from short-term fluctuations.
- Use past or future language only when the task establishes the time status.
- Group each city’s trend while comparing intersections and end points.
Sample report
The line graph compares the numbers of people visiting Cardiff and Dublin between 2018 and 2040, measured in millions.
Overall, Dublin starts with far more visitors but follows a downward pattern despite two temporary recoveries. Cardiff remains comparatively stable during the first half of the period and then rises sharply, finishing with by far the higher figure.
Cardiff receives approximately 1.5 million visitors in 2018. This number increases gradually to just over 2 million in 2024 and remains at a similar level in 2026 before falling back to about 1.5 million in 2032. It then climbs rapidly to almost 4 million in 2034 and reaches 4 million in 2036. Further growth takes the figure to 5 million in 2038 and 8 million by 2040.
By contrast, Dublin’s total falls steadily from 7 million in 2018 to 2 million in 2028. It then rebounds to 6 million in 2030, before dropping to 5 million in 2032 and 3 million in 2034. After a brief recovery to 4 million in 2036, the number declines again, reaching 3 million in 2038 and only 1 million at the end of the period.
Organisation: The overview contrasts the dominant directions. Each details paragraph then follows one city chronologically without switching repeatedly between lines.

Complete table example
Reasons adults attended the theatre
Approach
- Rank the categories within each period before writing.
- Highlight changes in both percentage and relative position.
- Group the earlier and current figures rather than listing cells randomly.
Sample report
The table compares the percentages of adults in London who attended the theatre for four different reasons 20 years ago and at the present time.
Overall, business events were the dominant reason two decades ago, whereas special occasions are now the most common motivation. Attendance for business and family trips has declined, while the proportions associated with special occasions and vouchers have increased.
Twenty years ago, 58% of surveyed adults went to the theatre for a business event, making this by far the largest category. Family trips ranked second at 27%. Much smaller shares attended for a special occasion or because a friend or relative had bought them a voucher, at 9% and 6% respectively.
Today, the pattern is different. Special occasions account for 55% of attendance, an increase of 46 percentage points. Business events have fallen to 20%, although they remain the second-largest reason. The proportion attending as part of a family trip has also declined, from 27% to 15%. Voucher-related attendance has risen more modestly to 10%, but it is still the least common of the four reasons.
Organisation: The overview identifies the change in the leading category. The details compare the complete ranking in each period and report every figure accurately.

Complete pie-chart example
Reasons for immigration to and emigration from the USA
Approach
- Identify the largest and smallest segments in each chart.
- Compare the same reason across the two populations.
- Use exact percentages where they support a meaningful contrast.
Sample report
The pie charts compare six reasons people immigrated to and emigrated from the USA in 2018.
Overall, joining family was the largest reason for immigration, while guaranteed employment accounted for the greatest share of emigration. Work-related reasons were important in both directions, but study represented a considerably larger proportion of departures than arrivals.
Among immigrants, 30% moved to join family members, and a further 26% were looking for work. Guaranteed employment accounted for 15%, while 12% arrived to study. The remaining proportions were 11% for other reasons and 6% for respondents who gave no reason.
For emigrants, guaranteed employment was the leading category at 29%, followed by study at 22%. Looking for work represented another 18%, meaning that employment-related reasons together accounted for almost half of departures. Only 13% left to join family, which was 17 percentage points lower than the corresponding immigration figure. No reason was stated by 14% of emigrants, and other reasons made up the smallest segment, at 4%.
Organisation: The response compares the leading categories in the overview and then reports immigration and emigration in separate, balanced paragraphs.

Complete process example
University application and enrolment procedure
Approach
- Identify the starting point, successful outcome and alternative branches.
- Describe loops explicitly when an applicant returns to an earlier stage.
- Use sequencing and passive forms only where they improve clarity.
Sample report
The flow chart illustrates the procedure that students follow after completing secondary education in order to apply for and begin a university degree.
Overall, applicants first complete an online form and submit it to an administrator. The application can then lead to enrolment, a request for supporting documents or rejection. Rejected candidates may cancel their application or apply for an alternative course, while successful applicants ultimately register and start their degree.
After finishing secondary school, a student completes an online application and sends it to the university administrator. If supporting documentation is required, the applicant spends two weeks compiling the necessary material before returning it to the administrator for reconsideration. When the application proceeds successfully, there is a two-week period before the student accepts a conditional offer and enrols.
The successful applicant next selects a degree subject, completes registration and starts the degree. A rejected application follows a different route. The candidate may cancel it, which ends the process, or complete another application for an alternative course. In the latter case, the new application is sent back to the administrator and enters the decision process again.
Organisation: The report explains the shared opening stages first, then separates the successful route, documentation loop and rejection options.

Complete map example
Changes planned for Oakville between 2010 and 2050
Approach
- State the dominant transformation before describing individual buildings.
- Group changes by location so the reader can follow the map.
- Use change verbs and passive forms without inventing reasons for development.
Sample report
The two maps compare the coastal city of Oakville in 2010 with its planned layout in 2050.
Overall, Oakville is expected to become considerably more developed. New educational, residential and entertainment facilities will be introduced, while the forest and library will disappear. The coastal road will also be transformed into a pedestrian area with hospitality businesses.
In the north, the old bus station in the north-west will be replaced by a new one, while a university and student accommodation will be constructed beside it. The forest in the north-east will be removed and a cinema will occupy this site. The city centre will remain in the middle of Oakville, but an e-scooter rental scheme will be added.
South of these facilities, the library on the western side will be replaced by new houses, and new flats will be built on the eastern side. The road running along the coast will become a pedestrianised area, and bars and restaurants will be established beside it. The sea itself and the central position of the city centre will remain unchanged.
Organisation: The overview summarises the shift towards development. The details move from north to south and distinguish replacements from additions.

Scoring
What Band 6, Band 7 and Band 8 look like in Task 1
Task 1 is assessed for Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The table is a practical summary of the public descriptors, not a guaranteed-score checklist.
Task Achievement
How fully and accurately the response addresses the task, selects key features and presents a clear overview supported by relevant details.
Coherence and Cohesion
How logically information progresses, how effectively paragraphs organise it and how naturally referencing and linking devices connect ideas.
Lexical Resource
The range, precision and appropriateness of vocabulary, including spelling, word formation and accurate language for data or change.
Grammatical Range and Accuracy
The variety and control of sentence structures, tense, agreement and punctuation, together with the frequency and impact of errors.
| Feature | Band 6 tendency | Band 7 tendency | Band 8 tendency |
|---|---|---|---|
| Task coverage | Addresses the task, but some key features or details may be missing, inaccurate or insufficiently developed. | Covers the requirements and presents a clear overview with appropriately selected key features. | Covers the requirements sufficiently and presents the important features clearly and precisely. |
| Organisation | Overall progression is visible, although paragraphing or cohesion may be mechanical. | Information is logically organised with clear progression and generally effective paragraphing. | Information is sequenced cohesively, and paragraphing is handled skilfully. |
| Vocabulary | Vocabulary is adequate but may be repetitive or imprecise, with some spelling or word-choice errors. | A sufficient range is used with flexibility; occasional errors do not prevent communication. | A wide range is used fluently and precisely, with only rare slips. |
| Grammar | Uses simple and complex forms, but errors remain noticeable. | Uses varied complex structures, with frequent error-free sentences. | Uses a wide range of structures flexibly, and most sentences are error-free. |

Common IELTS Writing Task 1 mistakes
Select key features and representative figures. A data inventory is not a summary.
Name the dominant patterns, stages or transformations instead of writing “many changes can be seen”.
Report what the visual shows. Do not invent explanations that are absent from the task.
Match the tense to the dates or process. Future projections and historical data require different forms.
Use logical groups and make the relationship between categories explicit.
A very long Task 1 response can reduce checking time and take time away from the more heavily weighted Task 2.
Use language that accurately fits the visual. Precision is more valuable than an impressive but inappropriate phrase.
Check whether the visual uses percentages, millions, tonnes, dollars or another measurement.

IELTS Academic Writing Task 1 FAQs
How many words should I write for IELTS Academic Task 1?
Write at least 150 words. A response below the minimum is penalised. Aim for a focused report rather than adding unnecessary material solely to increase the length.
How long should I spend on Task 1?
IELTS recommends about 20 minutes. The complete Writing test lasts 60 minutes, and Task 2 contributes twice as much as Task 1, so leave roughly 40 minutes for Task 2.
What are the four paragraphs in IELTS Writing Task 1?
A reliable structure is an introduction, an overview, a first details paragraph and a second details paragraph. Adapt the grouping to the task rather than forcing unrelated information into the template.
Do I need a conclusion in Academic Writing Task 1?
You normally need an overview rather than an opinion-based conclusion. The overview summarises the most important features; repeating it at the end is usually unnecessary.
Can I give my opinion in Task 1?
No. Academic Task 1 is a factual report of the supplied visual information. Do not speculate about causes or say whether a result is good, bad, surprising or desirable unless the task itself supplies that information.
How do I write an overview for Band 7?
Identify the dominant patterns or transformations and select the most important features. Avoid excessive figures in the overview, then support its claims accurately in the details paragraphs.
Which tense should I use in IELTS Task 1?
Use the tense required by the time period. Historical data generally needs past forms, current facts may use the present, and predictions require future language. Processes often use the present simple and passive voice when no time is specified.
How is IELTS Writing Task 1 scored?
Examiners assess Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each criterion contributes to the task band, and Task 2 carries twice the weight of Task 1 in the overall Writing score.
Can I use bullet points in the test?
No. The response must be written as connected text using full sentences and paragraphs. Planning notes are useful before writing, but they are not part of the final answer.
