IELTS Academic Writing Task 1

Cover: IELTS Academic Writing Task 1 — a line graph and bar chart on a desk beside a pen and a 20-minute timer
Short answer

IELTS Academic Writing Task 1 asks you to describe visual information — a graph, table, chart or diagram — in at least 150 words in about 20 minutes. You report the key features in full sentences, and you never give your own opinion here.

Level: B2. Task 1 is the shorter of the two IELTS Academic Writing tasks. You are given one piece of visual information and you describe what it shows — clearly, accurately and in your own words. This page explains the format, the marking, a reliable structure and a full sample answer, then points you to the course pages that build the skill.

By the end of this page you can…

…recognise every Task 1 prompt type, plan a four-paragraph answer, use the right language for trends and comparisons, and avoid the mistakes that cost the most marks.

IELTS Academic Writing at a glance

The Writing paper lasts 60 minutes and has two tasks, both of which you must complete (IELTS). Task 1 is the smaller job:

Feature Task 1
What you do Describe a graph, table, chart or diagram in your own words
Minimum length 150 words
Suggested time About 20 minutes
Weighting Counts less than Task 2 toward your Writing band
Answer form Full sentences — never notes or bullet points

Because Task 2 contributes twice as much as Task 1 to the Writing score (IELTS), spend about 20 minutes here and leave 40 for the essay.

What Task 1 can ask you to describe

In Task 1 you have to describe some visual information — a graph, table, chart or diagram — and all the information you need is in the image itself (IELTS). The common prompt types are:

  • Line graph — change over time (describe the trends).
  • Bar chart — compare quantities across groups.
  • Pie chart — proportions of a whole (percentages).
  • Table — numbers you must group and summarise.
  • Process diagram — stages of how something is made or works (describe in sequence).
  • Map — how a place changed, or two places compared (describe by position).

A line, bar, pie or table is about data. A process or map is about sequence or position, so you do not talk about trends — you describe stages or locations in order.

How the four marking criteria work

A certificated examiner marks each task on four criteria, weighted equally (IELTS):

Criterion What it rewards in Task 1
Task achievement Covering the data accurately, with a clear overview of the main features
Coherence and cohesion Logical order and smooth linking of ideas
Lexical resource A range of accurate, appropriate vocabulary
Grammatical range and accuracy Varied, correct sentence structures

A simple four-paragraph structure

  1. Introduction (1 sentence) — paraphrase the prompt: say what the visual shows, where and when.
  2. Overview (1–2 sentences) — the two or three biggest features, with no specific numbers.
  3. Detail paragraph 1 — the first group of data, with figures.
  4. Detail paragraph 2 — the second group, with figures and comparisons.

For a process or map, keep the introduction and overview, then replace the two detail paragraphs with the stages in order (process) or before/after description (map).

Useful language for Task 1

Job Language
Introduce The graph shows… / The chart illustrates… / The table gives figures for…
Overview Overall, … / The most striking feature is… / In general, …
Rising rose, increased, climbed, grew — a sharp rise, a steady increase
Falling fell, decreased, declined, dropped — a slight fall, a steep decline
No change remained stable, stayed constant, levelled off
Compare far higher than, roughly double, the same as, slightly below
Approximate about, just over, nearly, around, approximately

A sample Task 1 answer

This answer gives an introduction, a clear overview, grouped detail with figures, and a closing comparison — the shape examiners look for.

Recap card for IELTS Academic Writing Task 1 showing the four-paragraph plan and trend language

Quick recap before you practise.

How to say it

A few words in trend language trip up English learners — copy the stress.

  • steadily has three beats, stress on the first: STED-i-lee.
  • approximately is uh-PROK-si-mit-lee, stress on the second beat.
  • considerably is kuhn-SID-er-uh-blee, stress on the second beat.
  • figure is FIG-er in British English (the gu is a hard g).

Usage notes

  • No opinions. Task 1 is a report. Save phrases like I think for Task 2.
  • Tenses follow the dates. Past data takes the past simple; a process diagram with no dates takes the present simple (often passive: the beans are roasted).
  • Paraphrase the prompt in your introduction — copying it word for word is not rewarded.
  • Round sensibly. Just over 250,000 reads better than a long exact number lifted from the axis.
