The missing sentence that caps you at band 5
Task Achievement, one of the four criteria, requires an overview. An overview is one or two sentences that name the biggest pattern in the data without quoting specific figures: which country grew throughout, which two peaked and fell, what the general direction is. It is not a summary of your whole answer and it is not a conclusion.
If it is absent, Task Achievement cannot exceed band 5. That is a quarter of your Task 1 mark gone before the examiner has considered a word of your English, and it happens to candidates whose data description is otherwise accurate and well written. It is the single cheapest band available in the whole Writing paper.
Put it second, straight after a one-sentence paraphrase of the prompt, and signal it plainly. Overall is the clearest signpost and examiners do not mind it in the least.
Group the data, do not walk through it
The instinct is to take each row of the table in order and describe it. That produces four disconnected paragraphs and a Coherence score of 6 at best, because there is no organising idea holding the answer together.
Instead, group by behaviour. Two countries rose throughout, two peaked in the middle year and fell back. That single observation gives you your overview and your two body paragraphs at the same time, and it is what separates a band 7 response from a band 6 one more reliably than any amount of vocabulary.
Selecting matters as much as grouping. The task says to select and report the main features. A response that reports every figure has not selected anything, and completeness is not what is being rewarded.
A structure that works for every visual type
- 1Paraphrase the prompt in one sentence. Change the nouns and the verb, not just the word order.
- 2Overview. One or two sentences, the main pattern, no figures.
- 3Body paragraph one. The first group, with three or four supporting figures.
- 4Body paragraph two. The second group, compared back to the first.
Four paragraphs, around 180 words, twenty minutes. It fits every visual type in the table below with minor adjustments.
What each visual type is asking for
| Visual | Really about | How to handle it |
|---|---|---|
| Line graph | Change over time | Group lines that move together. Name the highest and lowest points and the moment the ordering changes, and ignore every wobble in between. |
| Bar chart | Comparison between categories | Compare across the categories first, then within them. The overview is usually which category leads and by roughly how much. |
| Pie chart | Proportions of a whole | Work in proportions rather than raw values: a third, just under half, a small fraction. With two pies, the overview is what changed between them. |
| Table | Several variables at once | The hardest to overview because everything is available. Find the one pattern that holds across rows, then support it with four or five figures rather than all twelve. |
| Process diagram | Stages in a sequence | Count the stages and say whether the process is linear or a cycle. That count is the overview. Then use the passive and sequencers throughout. |
| Map | Change in a place over time | Work by area rather than by feature: the north of the site, the area beside the river. The overview is whether the place became more built up, more open, or reorganised. |
The language of change, and how not to overuse it
Lexical Resource rewards precision more than variety. Using surged for a rise of two per cent is worse than using rose, because it is inaccurate. Match the word to the size of the movement.
| To express | Use |
|---|---|
| A large rise | rose sharply, climbed steeply, more than doubled, surged, increased dramatically |
| A small rise | edged up, rose slightly, crept up, grew marginally |
| A large fall | fell sharply, dropped steeply, plummeted, halved |
| No change | remained stable, held steady, levelled off, plateaued |
| A peak or low | peaked at, reached a high of, bottomed out at, fell to a low of |
| Approximation | just over, just under, roughly, approximately, in the region of, a little short of |
Write one now, against the clock
Twenty minutes, 150 words minimum. The model answer and examiner notes are underneath, but write yours before you read them. Reading the model first makes it almost impossible to see what your own answer is missing.
Writing Task 1
The table below shows the number of international students enrolled in higher education in four countries in 2015, 2020 and 2025, in thousands. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

| Country | 2015 | 2020 | 2025 |
|---|---|---|---|
| Canada | 172 | 388 | 426 |
| Australia | 294 | 372 | 281 |
| Germany | 236 | 302 | 379 |
| Japan | 152 | 228 | 196 |

Questions about Task 1
- What is an overview in IELTS Writing Task 1?
- One or two sentences naming the biggest pattern in the data, with no specific figures. Without one, Task Achievement is capped at band 5 however accurate the rest of your answer is. Write it as the second paragraph, immediately after your paraphrase of the prompt.
- How many words should Task 1 be?
- At least 150. Aim for about 170 to 190. Words copied from the prompt are excluded from the count, so a heavily copied introduction can leave you under length without realising.
- Should I include a conclusion in Task 1?
- No. Task 1 needs an overview, not both an overview and a conclusion. If you have written the overview near the start, stop once the data is covered.
- Can I explain why the figures changed?
- No, and it costs you. The task asks you to summarise and compare what is shown. Speculating about causes adds nothing the examiner can reward and eats the twenty minutes you have.
- How much of the data should I include?
- Enough to support your points and no more. Selecting is part of what is being marked. A response that reports every cell in the table without grouping anything is a list, and lists score poorly on Coherence.
- Is General Training Task 1 the same?
- No. General Training Task 1 is a letter, formal or informal depending on who you are writing to, with three bullet points you must cover. The twenty-minute limit and 150-word minimum are the same, but everything on this page about charts applies to Academic only.
