IELTS Writing Task 1: Complete Guide | IELTS Academic
IELTS Academic Writing Task 1 is the visual-description part of the IELTS Writing test. You are shown a chart, graph, table, map, or process diagram, and you write a short report that describes the main information in your own words. Your performance is scored on the 9-band scale used across IELTS Reading, Listening, Writing, and Speaking. Task 1 carries one-third of your overall Writing band; Task 2, the essay, carries the other two-thirds.
This guide covers the official format from ielts.org, the four criteria the examiner scores you on, the five visual types you can face, and the strategies that protect your Writing band when Task 1 looks unfamiliar.

What is the "Writing Task 1" question type?
IELTS Academic Writing Task 1 is the first of two tasks in the 60-minute IELTS Writing test. According to the official IELTS Academic Writing format, you must describe "some visual information in your own words", such as "one or more graphs, charts or tables" or "a diagram of an object, device, process or event".
You must write at least 150 words, and the recommended time is no more than 20 minutes. Writing fewer than 150 words is penalised on Task Achievement. Writing more is allowed but eats into the 40 minutes you need for Task 2.
The visual on Task 1 falls into one of five common types:
- Line graph or bar chart: data that changes over time or compares categories. See 30 chart and graph practice questions with sample answers.
- Table: data presented in rows and columns. See 30 table practice questions with sample answers.
- Map: changes to a place over time, or a comparison between two locations. See 30 map practice questions with sample answers.
- Process diagram: the stages of a process or how something works. See 30 process diagram practice questions with sample answers.
- Mixed visual: two visuals on related data (for example, a line graph plus a pie chart). See 30 mixed-visual practice questions with sample answers.
Your response must be written as a whole piece of connected text, in an academic or semi-formal style. Bullet points and notes are not allowed. Do not copy the wording of the prompt into your answer: copied text does not count toward the 150 words, and copying too much risks a plagiarism flag.
Strong opening sentence: "The line graph illustrates the change in the share of households connected to the internet in four countries, the UK, Germany, Brazil, and India, over a twenty-year period from 2000 to 2020."
Why it works: paraphrases the prompt (does not copy it), names the visual type, the unit, the time period, and the four countries. The next sentence is the overview: the main trend in 1 to 2 sentences (which countries are the highest, which are the lowest, the overall direction of change).

How "Writing Task 1" is scored
Your Task 1 response is scored on four equally-weighted criteria, each rated on the 9-band scale, per the official IELTS Writing band descriptors:
- Task Achievement: how well you address the visual, identify the main features, and use the data accurately.
- Coherence and Cohesion: how well your paragraphs are organised and how clearly your ideas connect.
- Lexical Resource: range and accuracy of vocabulary, especially the language for describing trends, comparisons, and proportions.
- Grammatical Range and Accuracy: range and correctness of grammar.
Each criterion is scored on the 9-band scale. The four scores are averaged to give your Task 1 band. The Task 1 band then combines with your Task 2 band in a weighted average to give your overall Writing band: Task 2 counts twice as much as Task 1.
Task 1 has its own specific pitfalls. Going under 150 words is penalised on Task Achievement. Listing every data point instead of selecting the main features is also penalised; the prompt asks you to "select and report the main features", not to describe everything. Copying the wording of the prompt into your answer does not count toward the word total and risks a plagiarism flag.
Tips to do well on "Writing Task 1" questions
Structure the report in four short paragraphs
A reliable Task 1 structure is four short paragraphs: (1) introduction that paraphrases the prompt and names the visual, (2) overview that names the main trends or features, (3) body paragraph on the first group of data, (4) body paragraph on the second group. The overview matters most for Task Achievement; the band 7 descriptor specifically rewards clear identification of main features. Do not skip it or bury it.
Paraphrase the prompt, do not copy it
Your first sentence should restate the prompt using different words. Prompt: "The chart shows the number of cars sold in Japan from 2000 to 2020.". Paraphrased opening: "The bar chart illustrates car sales in Japan over a 20-year period, from 2000 to 2020.". Three changes: shows → illustrates, chart → bar chart (be specific about the visual), from 2000 to 2020 → over a 20-year period. Copied wording does not count toward your 150 words and lowers your Lexical Resource score.
Select the main features, do not list everything
The instruction "summarise the information by selecting and reporting the main features" is the most important sentence on the page. A band 7 response identifies 2 to 4 main features (the highest value, the lowest value, the biggest change, the overall trend) and builds the response around those. A band 5 response tries to describe every data point and runs out of time. Spend the first 2 minutes looking at the visual and deciding what the main features are, before writing.
Use a range of trend vocabulary
The band 7 descriptor for Lexical Resource on Task 1 rewards range. Mix verbs of change (rise, fall, increase, decrease, climb, drop), nouns of change (a rise, a fall, an increase, a sharp drop), and adverbs and adjectives of degree (slightly, significantly, dramatically, marginally). Use each only once if possible. Repeating "increase" five times in a 160-word report puts a hard cap on your Lexical Resource score, even if every other criterion is strong.
How to practice "Writing Task 1" questions
Random practice does not raise your Writing band. What raises it is writing Task 1 responses at your current level, timing yourself to 20 minutes, and comparing your response to a sample answer at your target band. After every attempt, check your response against the four criteria: did your overview name the main features (Task Achievement)? Did you organise the data into clear paragraphs (Coherence and Cohesion)? Did you repeat the same trend verb three times (Lexical Resource)? Did you use the right tense for the data (Grammatical Range)?

Frequently asked questions
How long is IELTS Academic Writing Task 1?
The whole IELTS Writing test is 60 minutes, with two tasks. The recommended time for Task 1 is no more than 20 minutes, leaving 40 minutes for Task 2. The 20-minute target is recommended, not enforced, but every minute you take from Task 2 hurts your overall band because Task 2 carries twice the weight.
What is the minimum word count for IELTS Writing Task 1?
At least 150 words. Writing fewer than 150 words is penalised on the Task Achievement criterion. Writing more is allowed and not penalised on its own, but it costs you time you need for Task 2. Most strong responses sit comfortably above the 150-word minimum without going so long that they take time away from Task 2; IELTS does not publish a target word count beyond the minimum.
Does the visual type matter on IELTS Writing Task 1?
Yes, for the language you use. Line graphs and bar charts call for trend language (rise, fall, fluctuate). Tables call for comparison language (higher than, twice as many as). Maps call for spatial language (to the north of, replaced by). Process diagrams call for sequence language and passive voice (first, then; X is heated to).
Can I give my opinion on IELTS Writing Task 1?
No. Task 1 is a descriptive report, not an essay. Your job is to describe the visual, not to explain why the trend exists or to argue for an interpretation. Giving an opinion on Task 1 lowers your Task Achievement score because you have not addressed the requirements of the task. Save opinions for Task 2.
Does IELTS Writing Task 1 differ between Academic and General Training?
Yes. Academic Writing Task 1 is a visual description (chart, graph, table, map, or process diagram). General Training Writing Task 1 is a letter (formal, semi-formal, or informal). The two are completely different tasks, with different scoring criteria for Task Achievement. Task 2, by contrast, is broadly the same essay task across both versions.
How much does Task 1 count toward my IELTS Writing band?
Roughly one-third. Task 2 counts twice as much as Task 1, so your Writing band is a weighted average of one-third Task 1 and two-thirds Task 2. A strong Task 1 alone cannot rescue a weak Task 2, but a weak Task 1 can pull your Writing band down.
Conclusion
Task 1 is the part of the Writing test where structure matters more than creativity. A clear introduction, a strong overview, and two body paragraphs built around the main features of the visual will reliably score in band 6 to 7 range. The two habits that matter most are paraphrasing the prompt instead of copying it, and selecting the main features instead of describing every data point. Build both into your timed practice, and Task 1 protects your Writing band from quietly losing marks while you focus on Task 2.
