In 2000 the figure was 20. In 2005 it was 24. In 2010 it was 31. In 2015 it was 43.
IELTS Academic Task 1: listing every number is not the same as reporting the main features.
Learners often respond to uncertainty by describing every visible value. The result may be accurate sentence by sentence but difficult to read because the report never tells the reader what matters most.

Before writing detail, identify two or three dominant features that would still matter if small numbers were removed. Write those as an overview, then group supporting details around them.
Do not accept advice until you can see what changes in the response.
This is a QuickTalk Tutor practice example, not official test material and not a promised score. The criterion claim is checked against the official sources listed later in this article.
The data is copied in sequence, but the reader is not told the main feature. Academic Task 1 requires selection and a clear overview of significant trends or differences.
Overall, the figure rose throughout the period, with the sharpest increase occurring after 2010.
The meaning remains the learner’s. The job of the correction is to make that meaning clearer and more effective. One sentence alone cannot guarantee an OET grade.
Before details, write one sentence for the overall direction and one for the most important contrast. Then choose figures that prove those two statements.
If you can see the mistake but cannot identify what keeps causing it in your own work, the Diagnostic checks your exact route, skill, current criteria and target.
Selection is part of the writing task.
IELTS Academic Writing Task 1 asks test takers to describe visual information. The scoring criteria include Task Achievement, so coverage, key features and appropriate detail matter alongside language.
A line graph may need overall movement and major contrast; a process needs its direction and important stages; a map needs the main spatial change. One rigid “highest and lowest” script will not fit all visuals.
The diagnostic question is whether the learner cannot interpret the visual, cannot select, or can select but cannot express relationships clearly.
Use the current authority for the rule, then use your own unchanged work to decide what needs teaching.
Check the decision that is actually being made.
A useful diagnosis separates the parts of the performance before recommending more practice.
Visual type
Dominant features
Grouping
Language
Write the overview before the details.
- Study the visual for one minute without writing numbers.
- State two dominant features aloud.
- Write a two-sentence overview.
- Use a different visual to test whether selection survives the change.
Transfer check
A transferred skill identifies new key features without forcing the old chart’s language onto them.
Your words. Clearer and stronger, but still yours.
The work begins with the unchanged evidence, one clear priority and a practical correction. A fresh task then shows whether the change is available without copying the old answer.
Keep the original
Use the first response, recording or timing evidence.
Name one priority
Separate the strongest supported blocker from smaller issues.
Strengthen your words
Make the response clearer without replacing the learner’s thinking.
Change the task
Use fresh material to check whether the improvement transfers.
Do not pay for help you do not need.
Verify external requirements with the responsible organisation. Use teaching for the English performance that the evidence actually supports.
The blocker is already clear
Use focused teaching for the exact route and skill.
