Write an Academic Task 1 overview

An introduction identifies what the visual shows. An overview tells the reader its main patterns or differences. Detailed paragraphs then support those features with selected evidence.

These original short activities practise chart and table overviews, not process or map descriptions or a complete Task 1 report. Specialist accuracy review has not been completed. Choices and drafts stay in this open page and are not saved. This lesson does not grade writing, award a band or record mastery.

Select before you write

  1. Read the title, units, categories and dates. Separate percentages from counts and a single-year comparison from change over time.
  2. Look across the whole visual: main rises or falls, largest and smallest groups, changes of leader, and important exceptions. Not every visual contains every feature.
  3. Choose the features that give a representative picture. Write a brief connected overview before expanding details. Do not invent explanations or predict what happens next.
  4. Check each claim against the data. Distinguish “by the final year” from an exact unobserved crossing date, and “share fell” from “number fell”.

For these drills, aim for one or two connected sentences; this is a practice constraint, not an official sentence limit. An overview alone is not a full response. A complete Academic Task 1 response requires at least 150 words, with about 20 minutes suggested for the task. Figures can support key features; simply listing them does not replace an overview.

Read the whole pattern

Loan formats at a fictional university libraryPrinted-book share falls from 60% to 30%, while e-books rise from 10% to 45% and become the largest category at the final observation. Audiobooks are 30%, 30%, 25%. These shares do not reveal total loan counts. The exact values are also in the table below.

Choose the main picture

Which opening best summarises the library chart rather than just introducing it or listing details?

Stay within the evidence

What can the library percentages establish without knowing the total number of loans?

Revise an incomplete overview

The chart shows three loan formats. Print was 60% in 2012 and 45% in 2018. E-books increased because a new app was popular. Audiobooks were 30% in 2012.

This draft introduces the chart, lists a few details and invents a cause. Rewrite it to summarise the main picture using only the library data.

Compare an annotated revision

Overall, printed books lost share while e-books gained it and became the largest category by 2024. Audiobooks changed much less, ending slightly below their initial share.

  • printed books lost share while e-books gained it — Groups the contrasting directions. “Share” preserves the percentage unit and avoids claiming loan counts.
  • became the largest category by 2024 — Highlights the change of leader without inventing an exact crossover date.
  • Audiobooks changed much less — Adds the relatively stable series so the overview represents all three formats.

This is one possible overview, not an official model or an assigned band. No app or other cause is supported by the chart.

Write a fresh overview

Use the new solar-output chart. Identify the main directions and a meaningful ranking change, then write your overview before opening the comparison.

Annual solar electricity output at three fictional sitesNorth rises from 18 to 36 GWh and West from 12 to 32 GWh. East falls from 32 to 28 GWh. East is largest in 2016 and 2020; North leads in 2024, when West also exceeds East. Only the three stated years are observations. The exact values are also in the table below.

This lesson does not save drafts. Copy them elsewhere before reloading or leaving. Compare your wording yourself; no automated writing assessment runs here.

Compare and self-check

Overall, annual output increased at North and West but declined at East. East was initially the largest producer, whereas North led by 2024, when West had also moved ahead of East.

  • Include the main directions and a meaningful comparison, rather than every value.
  • Represent the contrasting or relatively stable series; avoid sweeping claims such as “all increased”.
  • Preserve the units and time scope. Do not invent causes, total counts or exact dates between observations.
  • Use connected sentences in your own wording. Different accurate overviews are possible.

Another accurate selection and wording can also work. Identify one improvement to your first attempt rather than treating a rewrite after seeing the model as independent mastery.

Avoid inventing a crossing date

Which comparison is supported by the solar chart?

Explain the distinction

Without looking back, explain why a falling percentage need not mean a falling count. Then explain why the introduction and overview have different jobs.

Check your reasoning

A count also depends on the total: 50% of 100 is 50, whereas 25% of 400 is 100. A lower share can therefore accompany a larger count. An introduction names the visual’s subject and scope; an overview summarises its main patterns. Neither replaces supporting detail in the full report.

Apply it to an existing full task

These links open the exact Task 1 question in the existing Writing Coach. Start with your own overview, then write the full report with supporting details. Use these two tasks for writing practice; automated feedback is currently unavailable for them. The workspace’s saving controls remain separate; this lesson does not submit a draft or request feedback.
