IELTS Academic Writing Task 1: Overview and Report Plan
In IELTS Academic Writing Task 1, you have 20 minutes and at least 150 words to summarise a graph, table, chart, map, or process diagram. Under the official Task Achievement descriptors, a clear overview of the main trends or stages is essential for reaching Band 6.0 and above.
By IELTSpeak Editorial TeamUpdated October 16, 2026
Why the overview decides Task Achievement
The overview is a two-sentence summary of the most noticeable patterns on the page: what rose or fell overall, which category dominated, or how many stages a process contains.
Place your overview immediately after your one-sentence introduction (as Paragraph 2). Writing it second guarantees that you include an overview even if the 20-minute clock gets tight during IELTS Writing practice.
A 4-paragraph Task 1 layout (165–190 words)
Keep Task 1 concise so you do not steal time from IELTS Writing Task 2. Four short paragraphs cover every requirement cleanly:
- Paragraph 1 — Introduction (1 sentence): paraphrase what the chart shows, the units, and the time period.
- Paragraph 2 — Overview (2 sentences): start with 'Overall,' and state two or three high-level trends or contrasts without quoting specific numbers.
- Paragraph 3 — Details Group A (3–4 sentences): compare the largest or rising categories using exact figures and dates.
- Paragraph 4 — Details Group B (3–4 sentences): compare the smaller, declining, or stable categories with supporting data.
What to put in the overview for each chart type
Match your overview lens to the type of visual prompt on the exam paper:
- Line graphs and bar charts over time: identify the overall upward or downward trend for each group and which category was highest at the start and end.
- Static tables, bar charts, and pie charts (one time point): highlight the highest and lowest figures overall and the sharpest gap between categories.
- Process diagrams: state the total number of stages, where the process starts and finishes, and whether it is linear or cyclical.
- Maps (before and after): summarise the overall transformation (for example, from a rural village into a denser residential hub) and the two largest changes.
Compare categories instead of listing every number
A common IELTS Writing mistake is describing every year from left to right like a spoken spreadsheet. Examiners reward selection and comparison.
Group similar lines or bars together, contrast extremes ('roughly three times as high as', 'overtook X in 2015', 'remained the smallest share'), and never speculate on real-world reasons that are not shown in the chart.
Key takeaway
Write a one-sentence introduction, a number-free overview in Paragraph 2, and two grouped comparison paragraphs.

Should I include numbers in the IELTS Task 1 overview?
Avoid specific percentages and figures in the overview (apart from the total number of stages in a process diagram). Keep the overview focused on big-picture trends and save exact numbers for Body Paragraphs 3 and 4.
