You have 20 minutes, a line graph, and a blank page. The most common mistake in IELTS Academic Writing Task 1 is not bad grammar. It is starting to write without a plan, listing every number on the graph, and running out of time before saying anything useful.
A fixed structure solves most of this. First, the facts about the task, so you know what you are aiming at.
What the task asks
In IELTS Academic, Writing Task 1 gives you a visual: a graph, chart, table, diagram of a process, or map. You describe and summarise the main information in writing. You must write at least 150 words, and the recommended time is about 20 minutes. The whole Writing paper lasts 60 minutes, and Task 2 (the essay) carries more weight in the final writing score, so most candidates plan to spend roughly 20 minutes on Task 1 and 40 on Task 2. (In IELTS General Training, Task 1 is a letter instead, which needs a different approach.)
Your answer is judged on four criteria: Task Achievement, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. For Task 1, it helps to remember that it is a report, not an opinion piece. You do not give your own views or explain the reasons behind the data unless the information itself gives them.
The four-paragraph structure
Paragraph 1: Introduction (one or two sentences)
Rewrite the question in your own words. Say what the visual shows, where, and when.
Question: The graph shows the number of visitors to a museum in 2010 and 2020.
You: The line graph illustrates how many people visited a museum over a ten-year period, from 2010 to 2020.
Change the verb (“shows” becomes “illustrates” or “compares”), and the structure if you can, but don’t change the facts.
Paragraph 2: Overview (two sentences)
This is the paragraph that many candidates forget, and it is one of the most useful. Give the big picture: the main trends or the biggest differences, without detailed numbers.
Overall, visitor numbers rose steadily over the period, with the most noticeable increase in the final three years. Weekend visits were consistently higher than weekday visits.
If you cannot say what the overall picture is in two sentences, look at the chart again before you start writing the details.
Paragraphs 3 and 4: Details
Now give specific data, grouped logically. Don’t describe every point. Choose key figures and compare them. You might group by time (the first half, the second half), by category (men and women), or by type (the highest and the lowest).
In 2010, the museum received approximately 40,000 visitors. This figure grew gradually to 55,000 in 2017 and then climbed sharply to reach 80,000 in 2020.
Notice that this sentence uses numbers, a time reference, and a verb that fits the trend. Each paragraph should have a clear theme, and the whole report should feel organised.
Language you will probably need
Trends: rose, increased, grew, climbed, fell, dropped, declined, remained stable, fluctuated.
Degree: sharply, steadily, gradually, slightly, dramatically.
Comparison: higher than, lower than, twice as high as, the highest, the lowest.
Approximation: approximately, around, just over, nearly, roughly.
Use a variety, but be accurate. “Doubled” means exactly twice, so don’t use it for a rise from 40 to 55.
Common mistakes
- No overview. Details alone don’t show that you can summarise.
- Copying the question word for word. Paraphrase it.
- Giving opinions. “This is a worrying trend” is not appropriate. Report what the data shows.
- Listing every number. Choose the key figures.
- Wrong tense. Use the past for past dates, the present for general facts, and future forms only for predictions the chart actually shows.
- Under 150 words. Short answers lose marks. Practise until you can reach about 170 to 190 comfortably.
A timing plan
Spend about three minutes studying the visual and planning. Spend about thirteen minutes writing, and the last four minutes checking numbers, tenses and spelling. These timings are a guide, not a rule, but practising with a clock soon shows you where you lose time.
