Executive Summary
In Academic Writing Task 1, you describe a graph, chart, table, process, or map in at least 150 words. According to official Band Descriptors for Task Achievement, presenting a clear overview of main trends or key features is required to achieve Band 7 or higher.
Without a clear overview, performance in Task Achievement is substantially limited even when individual figures are reported correctly.
What Belongs in the Overview?
The overview summarizes overall trends without quoting specific data figures.
- Line Graphs & Charts: Highlight overall increases, decreases, or dominant categories over the period.
- Maps: Highlight major structural additions or land-use changes.
- Process Diagrams: State total number of stages and starting/ending points.
Worked Overview Example
"Overall, while electricity generation from fossil fuels declined steadily over the twenty-year period, renewable energy sources experienced significant growth, eventually becoming the primary source of power."

Analyse Before Writing
Spend the opening minutes identifying:
- chart type;
- units and scale;
- categories being compared;
- time period;
- dominant trends;
- unusual exceptions;
- logical groups.
Do not begin by converting every visual label into a sentence. Task 1 rewards selection and comparison, so decide what matters before describing details.
Introduction and Overview
The introduction paraphrases what the visual presents:
The line graph compares the proportion of commuters using four forms of transport in a European city between 2000 and 2020.
The overview summarises the most important patterns without listing all figures:
Overall, car use declined across the period, whereas rail and cycling became increasingly common. Bus use remained comparatively stable.
The overview should allow a reader to understand the “shape” of the data before seeing detailed numbers.
Group Details Logically
Avoid describing categories strictly from left to right when stronger comparisons are available. Possible grouping principles include:
- categories that rise versus categories that fall;
- highest versus lowest;
- similar patterns;
- early period versus later period;
- stages of a process;
- maps showing additions, removals, and unchanged features.
Worked Data Example
Imagine car use falls from 60% to 42%, rail rises from 18% to 31%, cycling rises from 5% to 16%, and bus use changes from 17% to 11%.
A weak response lists four numbers with no relationship. A stronger detail paragraph might say:
Cars remained the most common mode, although their share fell substantially from 60% in 2000 to 42% in 2020. By contrast, rail use increased by 13 percentage points to reach 31%. Cycling also more than tripled, despite accounting for only 16% of commuters at the end of the period.
The paragraph selects comparisons and uses figures as evidence.
Language for Change
Match language to the data:
- rose gradually;
- increased sharply;
- remained stable;
- fluctuated;
- reached a peak;
- declined by ten percentage points;
- was approximately twice as high as.
Distinguish rose by 10% from rose to 10%. Use “percentage points” when comparing two percentages directly.
Process Diagrams
For a process:
- identify the start and endpoint;
- count the main stages;
- decide whether the process is linear or cyclical;
- group minor actions into meaningful stages;
- use passive voice where the actor is unknown or unimportant.
Do not invent causes or technical information that is absent from the diagram.
Maps
For maps, establish the time relationship and overall transformation. Group changes:
- construction or expansion;
- removal or replacement;
- relocation;
- features that remain unchanged.
Use location language precisely: north of, adjacent to, in the centre, along the eastern boundary.
Frequent Problems
- No clear overview.
- Every number is reported.
- Opinions or explanations are invented.
- Categories are described separately without comparison.
- Units or time periods are copied incorrectly.
- Trend language does not match the data.
- The response becomes a list rather than connected prose.
Editing Checklist
- Does the introduction accurately paraphrase the task?
- Does the overview identify the main features?
- Are details grouped rather than mechanically listed?
- Have I supported comparisons with selected figures?
- Are units, dates, and category names correct?
- Is change language mathematically accurate?
- Have I avoided personal opinion?
Task 1 is a report of supplied information. Clear selection, overview, and comparison matter more than decorative vocabulary.
A Twenty-Minute Practice Cycle
Use three minutes to analyse and plan, approximately fourteen minutes to write, and the remaining time to check. This is a training routine rather than an official allocation. During checking, compare every figure in the response with the visual, confirm that the overview is present, and remove any explanation that the task did not provide.
Practise overview writing separately. Take five charts and write only one-sentence introductions and two-sentence overviews. Then compare whether each overview identifies direction, dominance, stability, or the most important contrast without drowning in numbers.
Model Versus Memorised Language
Study model answers to observe selection and organisation, not to collect paragraphs for reuse. Phrases such as “the graph illustrates” are harmless, but a memorised overview cannot respond accurately to a new visual. The safest language is language that describes the data actually shown.
