What is IELTS Writing Task 1?
In IELTS Academic Writing Task 1, you are given a visual — a line graph, bar chart, pie chart, table, map, or process diagram — and asked to describe it objectively in your own words. You are not asked for your opinion. Your job is to summarise the key trends, make meaningful comparisons, and present the information accurately.
Examiners assess your Task 1 response across four equally weighted criteria:
- Task Achievement – Did you identify and describe the main features? Did you include relevant comparisons?
- Coherence and Cohesion – Is your response logically organised with clear paragraphing and linking language?
- Lexical Resource – Do you use a range of vocabulary accurately, including trend language and paraphrasing?
- Grammatical Range and Accuracy – Do you use a variety of sentence structures correctly, including tense and complex sentences?
Understanding all four criteria is essential. Many candidates lose marks not because their data description is wrong, but because they miss the overview paragraph (Coherence and Cohesion), repeat the same vocabulary (Lexical Resource), or use the wrong tense (Grammar).
If you are new to IELTS writing, it is worth reading our map writing sample to see how Task 1 principles apply to different visual types, and our guide on how to introduce variety in Writing Task 1 to improve your Lexical Resource score.
Band Descriptors
Always focus on these parameters to structure your essay. Since there are four criteria, try to compare your answers with each segment.
How to structure your Task 1 response ?
Every high-scoring Task 1 response follows the same four-paragraph structure. Aim for 14–18 sentences in total.
Introduction (2-3 Sentence):
Paraphrase the question in your own words. Mention what is shown, the time period (if any), and the units of measurement. Never copy the question directly — paraphrasing demonstrates vocabulary range to the examiner. Include “what”, “when”, and “where” information found in the graph title and axis labels.
Overview (2–3 sentences):
Summarize the two or three most obvious overall trends without quoting specific figures. This is the most critical paragraph — examiners specifically look for it when awarding Task Achievement and Coherence scores. Contrast trends that move in opposite directions. Do not state exact dates or data values here.
Body Paragraph 1 (5–7 sentences)
Group the data items whose trends are similar and describe them together. State the starting value, explain how the trend changed over time, and give the final value. Support each statement with specific figures from the graph. Use varied trend language — avoid repeating “increased” or “decreased” throughout.
Body Paragraph 2 (5–7 sentences)
Describe the remaining items — typically those with contrasting or different trends from Body Paragraph 1. Follow the same approach: start → change → end, supported by data. Make direct comparisons between items where possible to demonstrate analytical thinking.
Sample question and band 7+ model answer
The question
The graph below shows the percentage of households in three countries that owned a car between 1990 and 2020. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The graph shows three lines: Country A rising from 45% to 75%; Country B declining from 60% to 40%; Country C remaining stable at approximately 55% throughout the period.
Model Answer Band (7+)
The line graph illustrates the proportion of households owning a car in three different countries over a thirty-year period from 1990 to 2020.
Overall, car ownership in Country A rose considerably over the period, while Country B experienced a notable decline. Country C remained relatively stable throughout, showing very little change from start to finish.
In 1990, approximately 45% of households in Country A owned a car. This figure climbed steadily over the following two decades, reaching around 60% by 2005 before rising more sharply to peak at 75% in 2020. Country C also began the period at a similar level, at roughly 55%, and fluctuated only slightly, finishing at approximately the same proportion by the end of the period.
In contrast, Country B started with the highest level of car ownership at 60% in 1990. However, this proportion declined gradually over the thirty years, dropping to around 50% by 2010 and falling further to just 40% by 2020 — the lowest figure recorded among the three nations. By the final year, Country A had overtaken both Country B and Country C to become the country with the highest rate of car ownership.
Examiner Commentary
Task Achievement: All three data sets are covered with accurate supporting figures. The key features — the rise in Country A, the fall in Country B, the stability of Country C — are clearly identified. The overview paragraph isolates the main trends without repeating data from the body paragraphs.
Coherence and Cohesion: Paragraphing is logical and follows the four-part structure. Linking phrases such as “in contrast”, “however”, and “by the final year” create smooth flow. Information within each body paragraph is sequenced chronologically.
Lexical Resource: A good range of synonyms is used — “proportion”, “figure”, “level”, “rate”. Trend language is varied throughout: “climbed steadily”, “rising more sharply”, “declined gradually”, “fluctuated only slightly”.
Grammatical Range and Accuracy: The response uses a mix of simple and complex sentences. Passive constructions (“was recorded”), comparative structures (“had overtaken”), and time clauses (“by 2005 before rising”) demonstrate grammatical range without errors.
Essential Vocabulary of Task 1
Using a variety of trend language and hedging phrases is key to scoring well on Lexical Resource. Memorise at least two or three phrases from each category below.

Understanding band scores in IELTS Writing Task 1
One of the most searched topics around Task 1 is how the band scoring system works. This section answers the most common questions about marks, bands, and what your score actually means.
IELTS Writing Band Score Calculator
How many Marks is IELTS Writing Task worth?
Writing Task 1 is worth 33% of your total IELTS Academic writing band score. Task 2 carries the remaining 67%. Both tasks are marked on the same four criteria, each weighted equally within the task. Your writing band score is then averaged with your Listening, Reading, and Speaking scores to produce your overall band.
Important: Because Task 2 carries more weight, if you are short on time in the exam, always prioritise completing Task 2 over perfecting Task 1.
How to get band 7 in IELTS Writing Task 1?
A band 7 response consistently does the following:
- Covers all key features of the data with relevant, accurate supporting figures
- Includes a clear overview paragraph identifying the two or three main trends without listing data
- Uses a sufficient range of vocabulary with only occasional inaccuracies
- Demonstrates a variety of grammatical structures with only minor errors
- Is logically organised with clear paragraphing and cohesive devices used appropriately
The single most common reason candidates score band 6 instead of band 7 is a weak or missing overview paragraph.
How to get band 7+ in IELTS Writing Task 1?
To push from band 7 into 7.5 or band 8 territory, focus on these upgrades:
- Lexical precision: Instead of “increased a lot”, write “surged by nearly 30 percentage points” or “climbed sharply to reach a peak of 75%”.
- Grammatical complexity: Mix simple sentences with relative clauses and passive constructions. For example: “Country A, which began the period at just 45%, rose dramatically over the following three decades.”
- Analytical comparisons: Make cross-item comparisons explicit — “By 2020, Country A had overtaken Country B to become the highest-ranking nation.”
- Data grouping: Group items with similar trends together in one body paragraph to demonstrate higher-order analytical thinking.
