When preparing for IELTS Writing Task 1 Academic, most students are familiar with line graphs, bar charts, pie charts, and tables. However, two types of visuals often create confusion: maps and process diagrams. Unlike data charts, these tasks don’t involve numbers or percentages. Instead, they test your ability to describe changes over time, comparisons, and sequences of events using clear, accurate English.
This guide explains how to handle both maps and process diagrams, step by step, with vocabulary, structure tips, and practical strategies for scoring high.
In IELTS Writing Task 1 Academic, you must write at least 150 words in 20 minutes. The examiner assesses your writing on four criteria:
Task Achievement – Did you cover key features, make comparisons, and describe changes accurately?
Coherence and Cohesion – Is your writing logically organized, with linking words?
Lexical Resource – Did you use a wide range of vocabulary appropriately?
Grammatical Range and Accuracy – Did you use complex structures and correct grammar?
For maps and process diagrams, the focus is not on interpreting numbers, but rather on describing spatial relationships, transformations, and steps in a process.
You may see:
Two maps showing the same place at different times (past vs. present, present vs. future).
One map with a plan of an area or site layout.
Three maps showing progressive development over time.
Your job is to describe what has changed and highlight major transformations rather than every minor detail.
Introduction
Paraphrase the question.
Example:
“The two maps illustrate changes in the layout of a small town between 1990 and 2020.”
Overview
Summarize the main trends (expansion, modernization, conversion of land use).
Example:
“Overall, the town became more urbanized, with farmland replaced by housing and commercial buildings.”
Body Paragraphs
Divide the map into sections (north vs. south, left vs. right, or major vs. minor changes).
Use directional language: north, south, east, west, in the center, on the outskirts.
Compare past and present systematically.
Directional terms: north, south, east, west, northeast, southwest, etc.
Position words: in the middle, on the corner, next to, adjacent to, opposite, at the end of.
Change verbs: was replaced by, was converted into, expanded, demolished, constructed, redeveloped, relocated.
General phrases:
“The park was replaced by a shopping mall.”
“A new road was constructed to connect the residential area with the town center.”
“The farmland to the north was converted into housing.”
“Between 1990 and 2020, the rural area underwent significant development. The farmland in the north was replaced by a residential district, while a shopping center was constructed in the center. A new main road was built running from east to west, and the school in the south remained unchanged. Overall, the area became more urbanized, with agricultural land giving way to housing and commercial facilities.”
This example shows how to cover key changes without describing every tree or minor road.
Process diagrams show a sequence of steps. They may represent:
Natural processes (life cycle of a butterfly, water cycle, volcanic eruption).
Manufacturing processes (production of cement, electricity generation, recycling).
Man-made procedures (building construction, food preparation, traffic system operation).
Unlike maps, process diagrams are not about changes over time but about stages in a cycle or flow.
Introduction
Paraphrase the task.
Example:
“The diagram illustrates the process of producing electricity from geothermal energy.”
Overview
Describe the overall sequence (linear or cyclic).
Example:
“Overall, the process consists of five main stages, beginning with the collection of cold water and ending with the production of electricity.”
Body Paragraphs
Describe stages in logical order (first to last, clockwise, top to bottom).
Use passive voice frequently, since the actor is often unknown.
Example:
“Cold water is pumped underground into a geothermal chamber. There, it is heated by hot rocks and transformed into steam, which is then directed into a turbine…”
Sequence words: first, next, then, after that, subsequently, finally.
Passive verbs: is pumped, is heated, is collected, is released, is transported.
Cycle words: cycle, process, stage, step, phase.
Cause/effect words: as a result, consequently, which leads to.
“The process of recycling plastic bottles involves six stages. First, used bottles are collected from households and taken to recycling centers. Next, they are sorted into different categories, after which they are cleaned thoroughly. The plastic is then crushed and melted, producing raw material for new bottles. Finally, the new bottles are manufactured and distributed to stores. This cycle is repeated continuously.”
This type of answer highlights clear stages, logical flow, and appropriate academic language.
Students often describe every small item on the map or every arrow in the process. This wastes time and word count. Instead:
Focus on major changes or main stages.
Group similar features together.
Many students skip the overview, but it is essential for a high band score. Always summarize:
For maps: main transformations (e.g., urbanization, expansion, modernization).
For processes: overall structure (linear or cyclic, number of stages).
For maps showing past vs. present: use past tense (was, were).
For future plans: use future tense (will be built).
For processes: use present simple passive (is heated, is collected).
Repetitive words like “changed” or “built” lower your score. Build a bank of synonyms:
Changed → transformed, converted, redeveloped.
Built → constructed, erected, established.
Removed → demolished, eliminated, cleared.
Plan Before Writing – Spend 3 minutes analyzing the map or process. Identify main features and group them logically.
Write Clearly and Concisely – Avoid storytelling. Stick to factual descriptions.
Use Linking Devices – Moreover, in contrast, subsequently, overall.
Practice Describing Visuals – Look at sample maps and diagrams and try writing short summaries.
Check Grammar – Especially passive forms, articles, and prepositions.
Introduction – Paraphrase task.
Overview – Main changes.
Body 1 – Changes in the north/south, left/right, or first half.
Body 2 – Remaining changes.
Introduction – Paraphrase task.
Overview – General structure and number of stages.
Body 1 – First half of the process.
Body 2 – Remaining stages.
Maps and process diagrams may seem intimidating at first, but they are actually easier than charts because you don’t need to analyze numbers or trends. The key is to:
Identify major changes or stages,
Use clear descriptive vocabulary,
Organize your writing logically,
Include an overview,
Apply the correct tense and voice.
With practice, you’ll find these tasks highly predictable and manageable. A well-structured response with precise vocabulary and strong grammar can easily bring you closer to your target band score in IELTS Writing Task 1 Academic.
Task 1 requires a factual, objective description of a visual. For maps, you summarize location, layout, and changes over time. For process diagrams, you explain a sequence of stages (often in the passive voice). You must highlight key features, make comparisons where relevant, and present the information clearly in at least 150 words.
Use a simple four-part structure: Introduction (paraphrase the prompt), Overview (main trends or the whole cycle), Body Paragraph 1 (first half of changes or stages), and Body Paragraph 2 (remaining changes or stages). The overview is essential for Band 6+ because it shows global understanding, not just details.
For maps that compare past vs. present, use the past simple (e.g., “was replaced by”). For future plans, use the future (e.g., “will be constructed”). For process diagrams, use the present simple passive because the agent is often unknown (e.g., “water is heated,” “bottles are sorted”). Consistent verb tense improves coherence.
In map tasks, state the main transformations (e.g., urbanization, expansion, conversion of land use, new transport links). In process tasks, identify the overall flow (linear or cyclical), the number of stages, and the start and end points. Avoid minor details; give the examiner the “big picture.”
Prioritize features that affect the whole map or process: new roads, demolished buildings, major land-use changes, or pivotal process stages (inputs, transformations, outputs). Group similar items (e.g., “several new residential blocks in the north”) and omit trivial elements (individual trees, tiny footpaths) unless they illustrate a broader trend.
Use directional terms (north, south, east, west), position (adjacent to, opposite, at the corner, on the outskirts), and change verbs (constructed, converted, expanded, relocated, demolished, upgraded). Example: “The farmland to the northeast was converted into housing, while a ring road was constructed around the town center.”
Use sequence markers (first, next, subsequently, finally), passive structures (is filtered, is heated, is assembled), and cause–effect links (as a result, consequently, which leads to). Example: “The mixture is heated until it evaporates; consequently, vapor is condensed to form the final product.”
No. Unlike charts, maps and processes usually contain no numerical data. Your score depends on accurate description, logical flow, and appropriate language. Focus on spatial relationships, major changes, and the sequence of steps rather than calculations.
Adopt a clear contrast pattern. For instance, describe the 1990 map features first (north to south), then explain how those areas changed by 2020. Use comparative phrases: “formerly… now…,” “was replaced by…,” “remained unchanged,” “expanded into…,” and “gave way to…”. Keep the geography consistent to avoid confusing the reader.
Typical issues include skipping the overview, recounting every tiny detail, mixing tenses, writing subjectively (“beautiful park”), and using informal language. Another frequent error is misreading arrows or stage order in processes. Always double-check flow direction and stage labels before you write.
Create synonym families. For “change,” use transform, convert, redevelop, modernize. For “build,” use construct, erect, establish, install. For “remove,” use demolish, clear, eliminate. Vary linking devices: furthermore, in contrast, subsequently, meanwhile, overall. Collocations like “residential blocks,” “commercial hub,” and “transport corridor” sound natural and academic.
Write 150–190 words for efficiency; more is fine if concise. Spend 2–3 minutes analyzing, 12–14 minutes writing, and 2–3 minutes checking grammar and coherence. Planning helps you pick key features quickly and avoid rewriting under time pressure.
Accurate passive constructions, correct prepositions of place (in, at, on, to the north of), and well-formed complex sentences (relative clauses, subordinators). Example: “A new bypass, which links the industrial estate to the harbor, was constructed across the eastern edge.” Maintain subject–verb agreement and article use.
For linear processes, state a clear start and end, then move stage by stage. For cycles (e.g., water cycle), emphasize recurrence: “The process then returns to the initial stage.” Use phrases like “in a continuous loop,” “repeatedly,” or “the cycle then recommences,” showing that the output becomes the next input.
You can use key technical labels (e.g., “condenser,” “turbine”) for accuracy, but always paraphrase descriptions. Instead of copying “hot chamber,” you might write “a subterranean cavity heated by geothermal energy.” Paraphrasing demonstrates lexical flexibility, while precise labels ensure clarity.
Mark three items during analysis: (1) anchor points that did not change (school, river), (2) macro-changes (new road network, land-use conversion), and (3) notable additions or removals (sports center, factory). Your overview summarizes (2); your body organizes by location (e.g., north/south) referencing (1) and (3).
Identify inputs, transformations, and outputs. Count the stages and decide natural paragraph breaks (e.g., stages 1–3 in Body 1, stages 4–6 in Body 2). Ensure each stage is linked with sequence markers and that causes/results are explicit where relevant.
Avoid guessing beyond the diagram. If a function or direction is not shown, do not invent it. Use cautious language when necessary: “appears to,” “is likely,” or “is shown to.” Precision and restraint are valued over speculation in Task Achievement and Coherence.
Example: “Overall, the area underwent substantial urban development, with agricultural land in the north giving way to residential housing, while transport links expanded to connect the new estates with the town center.” This captures the essence without micro-details.
Example: “Overall, the linear process comprises six stages, beginning with the collection of raw materials and culminating in packaged products ready for distribution.” It names the start and end and states the number of stages—clear and complete.
Alternate with subsequently, afterwards, in the following stage, meanwhile, at this point, once completed. For contrast in maps, use by contrast, whereas, while. For results in processes, use thereby, as a result, which leads to. Variety improves readability and boosts the Lexical Resource score.
Prefer compass directions and precise spatial phrases: “to the northwest of,” “along the southern coastline,” “in the town’s center.” Use left/right only when the map’s orientation makes it unambiguous. Precision signals strong academic control.
They look for a clear overview, accurate coverage of key features, logical grouping and comparison, and avoidance of irrelevancies. Missing the overview or mis-sequencing stages can limit you to Band 5–6, even with good grammar.
Set a timer and write short overviews for different maps and processes without full essays. Build a personal vocabulary bank of map and process phrases. Compare your writing to model answers, focusing on overviews, sequencing, and verb forms. Consistent, targeted practice quickly raises your Task 1 performance.
