IELTS Academic, General & UKVI Syllabus

For IELTS, you are required to understand the skill of writing a clear and accurate overview for Academic Task 1 visuals. For revision, focus on these syllabus points:

• Recognize which visual features are essential for an overview.
• Summarize the main features, trends, or patterns without supporting details.
• Group or compare data where relevant (e.g. identify overall increases, decreases, similarities, or contrasts).
• Paraphrase the question prompt clearly and appropriately.
• Avoid including figures or excessive detail in the overview paragraph.
• Know the importance of placing the overview in Task 1 structure and using appropriate language.

Test Your Knowledge

Attempt these questions before reading this article. If you find some difficult or cannot remember the answers, remember to look more closely at that area during your revision.

1. What is the main purpose of the overview paragraph in IELTS Academic Task 1 writing?
2. Which of the following should NOT be included in an overview?
   a) A description of a major upward trend
   b) Exact numerical data from the chart
   c) Group summaries of main visual features
3. Where should the overview be placed in your IELTS Task 1 response for best effect?
4. True or false: It is acceptable for the overview to summarize key changes without using any specific numbers or percentages.

Introduction

In IELTS Academic Task 1, you must write at least 150 words describing a visual such as a graph, chart, table, or diagram. The overview is a critical paragraph summarizing the main features of the visual. A clear overview shows the examiner that you can select, organize, and summarize information – key skills for a high band score.

Key Term: Overview
A summary paragraph in IELTS Task 1 that highlights the most significant features or overall trends of the visual, without specific data or figures.

Key Term: Main Features
The most important trends, patterns, or differences in the diagram, table, or chart that must be mentioned for a complete summary.

Why the Overview Matters

The overview paragraph provides a “big picture” summary. You should highlight major trends, general changes, or significant comparisons, but not include numerical detail. Examiners expect to see this early in your answer – usually after the introduction.

A strong overview:

• Demonstrates task achievement by directly fulfilling the IELTS band descriptors
• Shows you can select key information, not simply list data
• Sets up a logical structure for the rest of your answer

What to Include in a Good Overview

Your overview should:

1. Summarize the most important patterns, trends, or groupings you see.
2. Comment on overall changes (e.g. “there was a general increase,” “the majority preferred X”).
3. Highlight noticeable exceptions or contrasts.
4. Avoid minor details or individual data points.
5. Avoid copying the rubric.

Key Term: Data Grouping
The selection and organization of similar data categories or time periods into summarizing phrases (e.g. "all countries except one saw a decline").

Organizing and Placing the Overview

The overview should come immediately after your introduction. You may use linking phrases such as “Overall,” “In summary,” or “It is clear that”.

The structure of a strong answer is usually:

1. Introduction (paraphrased question)
2. Overview (main features/patterns)
3. Body paragraphs (specific comparisons and data)

What NOT to Include

• Precise numbers, years, or percentages (save these for body paragraphs).
• Examples of single categories unless truly exceptional.
• Your own opinion or speculation.
• Any copied phrases from the exam question.

Key Term: Paraphrasing
Restating a question or data prompt using different vocabulary and sentence structure, without changing the meaning.

Writing Overview Language

Typical phrases for overviews:

• “Overall, ...”
• “It can be seen that ...”
• “The most noticeable feature is ...”
• “There was a steady increase/decrease ...”
• “The majority/minority ...”
• “While ... , ... also ...”
• “By contrast, ...”

Demonstrate variety by using these as sentence starters for your overview.

Worked Example 1.1

The bar chart below shows coffee sales in five European countries in 2010.

European coffee sales ranged from 40 to 110 tonnes across France, Germany, Italy, Spain, and Sweden in 2010.

Question: Write a clear overview for this bar chart.

Model Overview:
Overall, Germany recorded the highest sales, while France had the lowest. The data show a strong north-south difference, with northern countries generally consuming more coffee. Sales were highest in only one country and lowest in another.

Answer:
A good overview compares the main highs and lows, comments on general distribution, and avoids detailed numbers.

Worked Example 1.2

The line graph depicts the number of daily train passengers in London from 2000 to 2020.

Task: Produce a clear overview for the graph.

Model Overview:
Overall, the number of train passengers increased steadily throughout the period, with a sharper rise after 2015. The graph shows only upward movement, with no years of decline.

Answer:
Note the overall upward trend, and the absence of decreases. No years or specific numbers are included, but key trends and turning points are summarized.

Worked Example 1.3

The two pie charts show the main sources of income for a UK university in 1995 and 2005.

Task: Write a one-sentence overview for these pie charts.

Model Overview:
In summary, government funding was the largest source of income in both years, but the university became less reliant on it by 2005, as income from student fees and research grew.

Answer:
The main change is identified, as well as the most important category. No data details are given.

Exam Warning

A common mistake is including too much data or analysis in the overview. Avoid using statistics – focus on trends, groups, or overall changes only.

Revision Tip

When planning your Task 1, quickly note two or three key trends or groups before you start writing. This will make writing the overview easier and faster.

Summary

Effective overviews give the examiner a clear summary of the most important points, without detail. Your overview should summarize major trends, patterns, and contrasts, and must not include precise numerical information. The overview should follow the introduction, use suitable language, and set the stage for the rest of your answer.
