IELTS Writing Task 1 (Academic): Describing Visual Data

Academic Writing Task 1 asks you to describe a chart, graph, table, or diagram objectively in at least 150 words, in about 20 minutes. This is not an opinion task -- you never argue for or against anything here, you only report what the visual shows.

A strong structure has four parts: (1) an introduction that paraphrases the task prompt in your own words, (2) an overview -- one or two sentences stating the two or three most significant overall trends or features, written before the details, (3) body paragraph(s) grouping related data together with specific figures and comparisons, and (4) no separate conclusion is needed for Task 1.

The overview is the single most commonly missed element by lower-scoring responses -- many candidates jump straight into listing every number without ever stepping back to say what the data's main story actually is. Examiners specifically look for it.

Useful language for trends: rose/increased steadily, fell sharply, fluctuated, remained stable, peaked at, reached a low of. For comparisons: in contrast, whereas, similarly, by comparison. Vary your vocabulary rather than repeating "increased" in every sentence.

Practice this yourself using the Writing self-review tool linked from this course's exam-practice page -- write a response to a sample Task 1 prompt, then score yourself honestly against the four criteria.
