IELTS Writing Task 1 Academic 2026: How to Describe a Graph, Chart or Map
A step-by-step guide to IELTS Academic Writing Task 1 — how to structure your response, what to compare, the language to use for trends, and how Band 7+ responses differ from Band 5.

Task 1 (20 minutes, 150 words minimum) asks you to summarise visual data — a line graph, bar chart, pie chart, table, map or process diagram. You are NOT giving your opinion. You are selecting, organising, and describing the key features and trends, using accurate language and appropriate academic vocabulary.
The 4-paragraph structure
Para 1: Paraphrase the question (what the graph shows, time period). Para 2: The main/overall trend in 1–2 sentences — the single most important pattern across ALL the data. Para 3–4: Specific details with data points to support the overview. Do NOT describe every single number.
The 'overview' is your highest-value sentence
Band 7+ answers always include a clear overview sentence that captures the key trend without specific figures. Example: 'Overall, oil remained the dominant energy source throughout the period, while renewable energy grew the most proportionally.' Missing this is the single biggest reason for Band 5–6 scores.
Language for trends
Rise: increased, grew, rose, climbed sharply/steadily/gradually. Fall: decreased, fell, dropped, declined. Stable: remained constant, levelled off, plateaued. Describing a peak: reached a peak/high of X in [year]. Describing a low: fell to a low of X. Add adverbs (sharply, gradually, slightly, significantly) to show the degree of change.
Common Band 5–6 mistakes
Including personal opinion ('I think this is because...'), spending all 150 words on one data series and ignoring others, copy-pasting the task question word-for-word, using only 'increase' and 'decrease' with no variety, and forgetting to include actual figures from the chart.
Practise with a timed mock
Task 1 is worth one-third of your Writing band. Practise under timed conditions (20 minutes exactly) so you stop running out of time on Task 2. Take a free IELTS Writing mock on LandingPrep and compare your response to the model answer to see exactly where your band sits.
