In the Academic version of the IELTS exam, Task1 asks you to describe visual information a graph, table, chart, diagram or map in about 150 words. You have 20 minutes to produce a clear, factual report that summarises the main trends, compares data and highlights significant points.
For the General Training version, Task1 is a letter-writing task (formal, semiformal or informal). This guide focuses on the Academic version, which many testtakers find more challenging.
Common Question Types
Line graph shows change over time.
Bar chart compares quantities across categories.
Pie chart displays parts of a whole.
Table presents raw numbers.
Mixed chart combines two or more of the above.
Process diagram explains how something works.
Map shows changes in a location.
Although the visual differs, the core skills remain the same: identify key features, organise them logically and use a range of grammatical structures.
Recommended Structure (150180 words)
Introduction (12 sentences) paraphrase the task prompt. Use synonyms and change the grammatical structure.
Overview (23 sentences) give a highlevel summary of the main trend(s) or the most striking differences. No data is required here, just a general picture.
Body Paragraph1 (45 sentences) describe the most important details: highest/lowest values, biggest increase/decrease, etc. Use data to support each point.
Body Paragraph2 (45 sentences) cover the remaining significant features, compare and contrast where relevant, and note any anomalies.
This plan ensures you meet the wordcount requirement, avoid repetition and keep the report coherent.
