IELTS Task 1 Trends: A 3-Step Method With a Model Answer
Quick answer: Paraphrase the question in one sentence, write an overview of the two or three biggest changes with no numbers, then give grouped details with key figures in two body paragraphs. Aim for 170 to 190 words in about 20 minutes, and never add opinions or reasons.↗ Share on X
To describe trends in IELTS Writing Task 1, use three steps: (1) paraphrase the question in one sentence, (2) write an overview of the two or three biggest changes with no numbers, and (3) give the details in two body paragraphs, grouping similar trends and supporting each one with exact figures and time points. The overview is the step most candidates skip, and it is the one examiners look for first. Aim for 170 to 190 words in about 20 minutes.
Below you will find each step with example sentences, a vocabulary table for trends, and a full model answer.

IELTS Task 2 Body Paragraphs: The 4-Step Plan for Band 8 →Task 1 trend questions show data that changes over time: a line graph, a bar chart with years, or a table with dates. You must write at least 150 words in about 20 minutes. Task 1 counts for one third of your Writing score; Task 2 counts for two thirds.
You are marked on four criteria, each equally weighted:
| Criterion | What it means in simple words | How to score well on trends |
|---|---|---|
| Task Achievement | Did you report the main features accurately? | Clear overview, key numbers, no opinions |
| Coherence and Cohesion | Is it organized and easy to follow? | Logical grouping, linking words used naturally |
| Lexical Resource | Range and accuracy of vocabulary | Varied trend verbs and nouns, correct collocations |
| Grammatical Range and Accuracy | Range and accuracy of grammar | Mix of simple and complex sentences, correct tenses |
Two rules matter most for trends: do not give your opinion or reasons (you only describe what the data shows), and use the correct tense (past for past years, future forms like "is expected to" for projections).

Step 1: How do you write the introduction?
Paraphrase the question in one sentence. Change the words, but keep the meaning. Say what is shown, where, and when.
Question: "The graph below shows the number of visitors to three museums in London between 2010 and 2020."
Introduction: "The line graph illustrates how many people visited three London museums over a ten-year period starting in 2010."
Quick paraphrasing swaps:
- shows → illustrates / compares / gives information about
- the number of → how many / the figures for
- between 2010 and 2020 → over a ten-year period / from 2010 to 2020
Do not copy the question word for word. Copied words are not counted toward your total, and copying lowers your vocabulary score.
Step 2: How do you write the overview?

IELTS Speaking Part 2: The 4-Step Story Plan for Band 8 →The overview is a short paragraph of one or two sentences that describes the big picture. Imagine telling a friend what the graph shows in five seconds. Usually you mention:
1. The overall direction of the main lines (up, down, stable).
2. The biggest or smallest item, or a major change in ranking.
No specific numbers go in the overview. Numbers belong in the details.
Example overview: "Overall, visitor numbers rose at the Science Museum and the British Museum, while the Natural History Museum saw a decline. The British Museum was the most popular throughout the period."
Start with "Overall," or "In general," so the examiner sees your overview immediately. Without a clear overview, it is very hard to get above Band 5 in Task Achievement.
Step 3: How do you write the body paragraphs?
Write two body paragraphs. The key is grouping: put similar trends together instead of describing each line one by one in order.
Common ways to group:
- By trend: paragraph 1 for items that increased, paragraph 2 for items that fell.
- By time: paragraph 1 for the first half of the period, paragraph 2 for the second half.
- By size: paragraph 1 for the biggest item, paragraph 2 for the smaller ones.
In each paragraph, include:
1. The starting point (the figure at the first year).
2. The change (how it moved, using trend language).
3. Any peak, lowest point, or crossover (where one line passes another).
4. The end point.
You do not need every number. Choose the important ones: start, end, highest, lowest, and crossing points.
Which words describe trends best?
Learn these in pairs: a verb version and a noun version. Using both gives you sentence variety.
| Direction | Verb + adverb | Adjective + noun |
|---|---|---|
| Up | rose sharply, increased steadily, climbed gradually | a sharp rise, a steady increase, a gradual climb |
| Down | fell dramatically, dropped slightly, declined steadily | a dramatic fall, a slight drop, a steady decline |
| No change | remained stable, stayed the same, leveled off | a period of stability, a plateau |
| Up and down | fluctuated | a fluctuation |
| Highest point | peaked at, reached a high of | a peak of |
| Lowest point | hit a low of, bottomed out at | a low of |
Useful sentence patterns:
- "Visitors to the Science Museum rose steadily from 2 million in 2010 to 3.5 million in 2020."
- "There was a sharp fall in visitor numbers at the Natural History Museum between 2014 and 2016."
- "The British Museum peaked at 6.8 million in 2018 before dropping slightly to 6.2 million."
- "In 2015, the Science Museum overtook the Natural History Museum."
- "Figures remained stable at around 4 million for the next three years."
Prepositions are where many candidates lose marks. Remember:
- rose from X to Y
- rose by 2 million (the size of the change)
- peaked at 6.8 million
- a rise in visitors of 20%
What does a full model answer look like?
Here is a complete answer to the museum question using made-up figures for practice (about 180 words):
The line graph illustrates how many people visited three London museums over a ten-year period starting in 2010.
>
Overall, visitor numbers rose at the Science Museum and the British Museum, while the Natural History Museum saw a decline. The British Museum was the most popular throughout the period.
>
The British Museum began with around 5 million visitors in 2010. This figure climbed steadily to a peak of 6.8 million in 2018, before falling slightly to 6.2 million by the end of the period. The Science Museum showed a similar upward pattern, rising gradually from 2 million to 3.5 million over the decade.
>
In contrast, the Natural History Museum started at 4 million visitors, higher than the Science Museum. Its numbers remained stable until 2014, after which there was a sharp drop to 2.5 million in 2016. In 2016, the Science Museum overtook it, and the Natural History Museum ended the period at just under 2.5 million, the lowest of the three.
Notice: no opinions, no reasons ("because of tourism"), past tenses throughout, and the overview contains no numbers.
What mistakes keep candidates at Band 6?
- No overview, or an overview hidden at the end with numbers in it.
- Describing every single data point in order, like reading a list. This is called "data dumping."
- Repeating "increase" five times. Use the table above for variety.
- Wrong tense, especially present tense for past data.
- Giving reasons the data does not show.
- Writing too much. Going far past 200 words wastes time you need for Task 2, which is worth more.
How should you practice this week?
1. Find five official or reputable sample trend graphs.
2. For each, write only the introduction and overview in 5 minutes. Do this until overviews feel automatic.
3. Then write two full answers under a 20-minute timer.
4. Check each answer against this list: paraphrased intro, overview with "Overall" and no numbers, grouped body paragraphs, correct prepositions, no opinions.
5. If possible, get feedback from a qualified IELTS teacher, since self-checking misses grammar errors.
Your next step
Take one line graph today and write just the overview, two sentences starting with "Overall," with no numbers. Time yourself: aim for under three minutes. Once you can do that reliably, you have fixed the single biggest weakness in most Task 1 answers.
FAQ
How many words should IELTS Writing Task 1 be?
At least 150 words. Around 170 to 190 words is a safe target that leaves enough time for Task 2, which is worth twice as much.
Should I put numbers in the Task 1 overview?
No. The overview describes the big picture, such as the overall direction and the largest item. Specific numbers go in the body paragraphs.
Can I give reasons for the trends in Task 1?
No. Task 1 asks you to describe the data only. Explaining causes that the chart does not show can lower your Task Achievement score.
What tense should I use to describe trends?
Use the past tense for past years, the present for current data, and forms like 'is expected to' or 'is predicted to' for future projections.
