Ayesha from Bengaluru described each bar in the chart accurately. Her Task Achievement score stayed at Band 5.

A good overview is two or three sentences that state the main trends, differences or stages, without detailed figures. The public band descriptors link a clear overview to Band 7 in Task Achievement, so it is the paragraph to get right first.

What do the band descriptors say about the overview?

The public Writing band descriptors, updated in 2023, describe Academic Task 1 like this:

Band Task Achievement (Academic)
5 Detail may be recounted mechanically, without reference to the bigger picture.
6 A relevant overview is attempted; information is selected and supported with figures.
7 A clear overview; data categorised; main trends or differences identified.

The examiner comments on the Task 1 sample scripts on the IELTS website point the same way. Four of the seven comments mention a missing, unclear or incomplete overview.

What goes into an overview?

Choose two or three of these main features:

  • the overall direction over time, or the highest and lowest categories in a chart for one date;
  • the biggest change, or the biggest difference between groups;
  • the number of stages, if the visual shows a process.

Keep figures out of this paragraph. They belong in the detail paragraphs, as our guide to describing graphs, charts and tables explains.

Where does the overview go?

Both of these placements work, and the choice is yours. Writing it straight after your paraphrased introduction gets it done even if time runs short. Putting it at the end makes it a summary.

An article on the IELTS website says Task 1 needs no separate conclusion, and that the overview can close the answer if it is not near the start.

Practice: from a data-heavy paragraph to a clear overview

Practice task (written for this post)

You should spend about 20 minutes on this task.

The table below shows the average weekly hours spent on four leisure activities by teenagers in Country A in 2005 and 2025.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Invented data for practice:

Activity 2005 (hours/week) 2025 (hours/week)
Reading books 6 2
Video streaming 5 18
Outdoor sports 10 7
Social media 4 15

A data-heavy “overview” like this one is just a list of figures:

Incorrect: “Overall, streaming rose from 5 to 18 hours, social media climbed from 4 to 15, reading dropped from 6 to 2, and sports fell from 10 to 7.”

Correct: Say which activities rose and which fell, in words, and keep the hours for the detail paragraphs.

Model overview (illustrative Band 7)

Overall, teenagers spent much more time on the two online activities in 2025 than in 2005, while the time given to reading and outdoor sports fell. Video streaming showed the largest rise and replaced outdoor sports as the activity that took up the most time.

Why it works:

  • Task Achievement: it states the main contrast and the standout change, with no detailed figures.
  • Coherence and Cohesion: the first sentence sorts the activities into two groups, and the second picks out one.
  • Lexical Resource: “much more time”, “fell” and “the largest rise” give the trends in words.

Three questions to find your overview fast

Ask these in your planning minutes, whatever the visual.

First, what is the overall direction? In a line graph, see whether the lines mostly rise, fall or fluctuate.

Second, which categories are highest and lowest? Third, which change is biggest? For a table, our post on describing a table shows how to find the largest gaps between rows or years.

Tip

After writing the overview, scan it for digits. Any digit you find belongs in a detail paragraph.

Key Takeaways

  • The descriptors link a clear overview to Band 7 in Task Achievement.
  • State trends, differences or stages in words, not detailed figures.
  • Ask three questions: overall direction, highest and lowest, biggest change.
  • Place the overview after the introduction or at the end.

The bottom line: A good overview is one you could say to a friend on the phone without using a single number.
