IELTS Academic Writing Task 1 Templates: Graphs, Charts, Maps & Processes
Academic Writing Task 1 asks you to describe visual information — a graph, chart, table, map, or process diagram — in at least 150 words within 20 minutes. You are not asked for your opinion. Instead, you must select, compare, and report the main features of the data, making comparisons where relevant.
Many test-takers struggle with Task 1 because they try to describe every single data point. The key is selectivity: identify the most significant trends, the highest and lowest values, and any notable comparisons. The templates below give you a reliable sentence-by-sentence structure for every question type, so you spend less time wondering what to write and more time writing well.
General Task 1 Structure (All Question Types)
Regardless of the visual type, every Task 1 response should follow this 3-part structure:
- Introduction (1-2 sentences): Paraphrase the question — say what the visual shows without copying the exact wording
- Overview (2-3 sentences): Summarize the most important overall trends or features — this is the most critical paragraph for your band score
- Body paragraphs (2 paragraphs, 3-5 sentences each): Provide specific data, numbers, and comparisons to support your overview
The overview is not optional. Band 7+ descriptors require you to present a clear overview of main trends. Skipping the overview typically caps your Task Achievement score at band 5, no matter how accurate your details are.
Template 1: Line Graph
Line graphs show how data changes over time. Your job is to describe the overall trend (rising, falling, stable, fluctuating) and highlight any significant turning points.
Introduction Template
"The line graph illustrates [what the data shows] in [location/context] between [start year] and [end year], measured in [units]."
Example: "The line graph illustrates the number of international tourists visiting three European countries between 2000 and 2020, measured in millions."
Overview Template
"Overall, [main trend for the most prominent line]. In contrast, [secondary trend or comparison]. By [end of period], [final comparison between key data sets]."
Example: "Overall, Spain experienced the most significant growth in tourist numbers over the period. In contrast, Greece saw a modest rise followed by a decline after 2015. By 2020, Spain attracted roughly twice as many visitors as Italy."
Body Paragraph Template
"In [start year], [data point]. Over the following [time span], [describe the change — rose/fell/remained steady]. This figure reached [peak/trough] of [number] in [year], before [subsequent change]. By [end year], [final data point]."
Key Vocabulary for Line Graphs
- Upward trends: rose, increased, climbed, grew, surged, soared
- Downward trends: fell, declined, dropped, decreased, plummeted, dipped
- Stability: remained steady, stayed constant, leveled off, stabilized, plateaued
- Fluctuation: fluctuated, varied, oscillated
- Degree: sharply, dramatically, significantly, gradually, slightly, marginally, steadily
Template 2: Bar Chart
Bar charts compare quantities across categories. They can show data for a single time period or multiple periods. Focus on which categories are highest/lowest and any notable differences.
Introduction Template
"The bar chart compares [what is being compared] across [number] [categories/countries/groups] in [time period/year]."
Overview Template
"Overall, [which category is highest] had the highest [measure], while [lowest category] had the lowest. [Optional: note a pattern, such as 'developed nations generally scored higher than developing ones']."
Body Paragraph Template
"[Category A] recorded the highest figure at [number], followed closely by [Category B] at [number]. [Category C] and [Category D] had considerably lower values, at [number] and [number] respectively. Notably, [any interesting comparison or exception]."
Template 3: Pie Chart
Pie charts show proportions. You should compare the relative sizes of segments and note which are largest and smallest.
Introduction Template
"The pie chart(s) show(s) the proportion of [what] in [context/location] in [year/period]."
Overview Template
"Overall, [largest segment] accounted for the largest share of [total], while [smallest segment] made up the smallest proportion. [Optional second observation about relative sizes or changes between charts]."
Body Paragraph Template
"[Largest segment] represented [percentage]% of the total, making it the dominant category. [Second segment] comprised approximately [percentage]%, roughly [comparison — 'half/a third/double'] that of [largest segment]. The remaining categories — [list] — each accounted for less than [percentage]%."
Key Vocabulary for Proportions
- Large shares: dominated, accounted for the majority, comprised the largest share, represented the highest proportion
- Small shares: made up a negligible proportion, constituted a minor share, accounted for merely [X]%
- Comparisons: roughly equivalent, approximately double, three times as large, marginally higher than
Template 4: Table
Tables present data in rows and columns. The challenge is that tables contain a lot of numbers — you must be selective and focus on the most significant patterns.
Introduction Template
"The table provides data on [what the table shows] for [number of categories/countries] in [time period]."
Overview Template
"Overall, [what stands out — e.g., which row/column has the highest values]. Additionally, [secondary pattern — e.g., a trend across time or a notable gap between groups]."
Body Paragraph Template
"Looking at [first category/time period], [highest value] recorded [number], which was [comparison] higher than [lowest value] at [number]. In [second category/time period], [describe the change or comparison]. [One more data point with comparison]."
For tables, group your data logically. If the table has rows for countries and columns for years, organize your body paragraphs either by country or by time period — not both randomly. Consistency in organization is rewarded under Coherence and Cohesion.
Template 5: Process Diagram
Process diagrams show how something is made, how something works, or the stages of a natural or industrial process. You must describe the sequence of steps clearly using the passive voice and sequencing language.
Introduction Template
"The diagram illustrates the process by which [product is made / natural phenomenon occurs / system operates], from [first stage] to [final stage]."
Overview Template
"Overall, the process involves [number] main stages, beginning with [first stage] and ending with [final stage]. It is [a linear process / a cyclical process / divided into two main phases]."
Body Paragraph Template
"In the first stage, [raw material/input] is [past participle — collected/harvested/heated/mixed]. Following this, [it/the material] is [next step]. Once [condition is met], [next action occurs]. The [product/material] is then [next step], which involves [additional detail]."
Key Vocabulary for Processes
- Sequencing: first, initially, at the first stage, subsequently, following this, next, then, after that, finally, in the final stage
- Passive constructions: is collected, is transported, is heated to, is mixed with, is allowed to cool, is packaged and distributed
- Transitions: once, after, before, during, while, at this point, simultaneously
Template 6: Map / Plan
Map questions show changes to a location over time, or compare two alternative plans for a site. You need to describe what changed, what stayed the same, and use compass directions and relative positions.
Introduction Template
"The two maps compare [location] in [year 1] and [year 2], showing the changes that took place over this period."
Or for plans: "The two plans show alternative proposals for [what — e.g., the redevelopment of a town center]."
Overview Template
"Overall, [location] underwent significant development between [year 1] and [year 2], with [general description of change — e.g., agricultural land being replaced by residential and commercial areas]. The [one feature that remained unchanged]."
Body Paragraph Template
"In [year 1], the [direction — northern/eastern] part of [location] was [description — farmland/woodland/undeveloped]. By [year 2], this area had been converted into [new use — a housing estate/shopping center]. Similarly, the [feature] to the [direction] was replaced by [new feature]."
Key Vocabulary for Maps
- Location: to the north/south/east/west of, in the northern/eastern section, adjacent to, opposite, in the center, on the outskirts
- Change: was replaced by, was converted into, was demolished and rebuilt as, was extended, was relocated to, was constructed
- No change: remained unchanged, was retained, continued to occupy the same position
Time Management for Task 1
You have only 20 minutes. Here is how to allocate your time:
- 2 minutes: Read the question and study the visual — identify 2-3 key features
- 3 minutes: Plan your overview and decide which details to include
- 12 minutes: Write your response using the templates
- 3 minutes: Proofread for grammar, spelling, and missing data
Common Mistakes to Avoid
- Describing every data point: Be selective — examiners reward your ability to identify key features, not your ability to list every number
- Missing the overview: This is the single most impactful paragraph for your score. Always write it before the body paragraphs
- Using opinions: Task 1 is objective description. Never write 'I think' or explain why the data looks the way it does
- Copying the question word-for-word: Paraphrase the introduction. 'The chart shows' instead of repeating the exact question wording
- Writing fewer than 150 words: There is a penalty for under-length responses. Aim for 170-190 words
