IELTS Academic Writing Task 1: how to describe graphs and charts

The four-part structure

• Introduction: paraphrase what the visual shows (what, where, when, units).
• Overview: 2–3 sentences on the biggest patterns — highest/lowest, overall rise/fall, any turning point. This is the single most important paragraph.
• Body 1: report and group the first set of key figures with data.
• Body 2: the remaining figures, compared and grouped logically.

Write a real overview — it's where bands are won

Examiners look specifically for a clear overview of main trends; without one you are capped around band 5 for Task Achievement. Do not list every number — step back and say what the data does as a whole.

A useful test: could someone understand the general story from your overview alone, without seeing the chart? If yes, it's doing its job.

Select and group — don't describe everything

Task Achievement rewards selecting the key features and supporting them with figures, not copying the whole table. Group similar items (all the categories that rose, the two that stayed flat) so your writing is organised, not a list.

The language of change

• Verbs: rose, increased, climbed, fell, declined, dropped, fluctuated, levelled off, plateaued.
• Adverbs/adjectives: sharply, steadily, gradually, dramatically, slightly — a sharp rise / rose sharply.
• Comparisons: twice as high as, the largest, roughly a third of, compared with.
• Approximation: just over, nearly, around, approximately — accurate but natural.

Common mistakes that cap you at 6

• No overview, or an overview buried in the detail.
• Explaining why the trend happened (that's not asked and wastes words).
• Under 150 words, or copying the question wording without paraphrasing.
• Listing every data point instead of grouping the key ones.
