How to Write the Introduction of a Report | Opening Examples and Common Mistakes
The "Introduction" is an important part of a report because it tells the reader the topic, problem awareness, purpose, and flow of the main text. If you begin with an overly long conclusion or only broad generalities, it becomes unclear what the report will actually discuss. This article organizes useful opening patterns, expressions, and examples to avoid.

How to Write the Introduction of a Report | Opening Examples and Common Mistakes
The introduction is the entrance to the report. By reading it, the reader should understand what will be discussed, why it matters, and from what perspective. It therefore needs to present the topic and question rather than simply offer a greeting or personal reaction.
If you are unsure how to begin, organize the introduction briefly in the order of background, problem awareness, purpose, and structure.
Role of the introduction
The role of the introduction is to provide the background needed before the main discussion. Briefly explain the context, clarify the focus of the assignment, and state what the report will discuss.
A good introduction tells the reader what question the report is trying to answer. If the topic is too broad or the opening consists only of personal impressions, the direction of the body becomes difficult to see.
| Element | Role | What to include |
|---|---|---|
| background | Present the background to the topic. | Course content, social background, or an overview of the relevant institution or system |
| Problem awareness | Explain why the issue is being addressed. | Question, problem, or point of disagreement |
| purpose | State what the report aims to clarify. | What the report will examine |
| Structure | Show the flow of the body. | For example: first, second, and finally |
Basic pattern
An introduction becomes more stable when it contains four elements: background, problem awareness, purpose, and structure. They do not all need to be lengthy. In a short report, one sentence for each may be sufficient.
For example: "In recent years, XX has become an important issue. However, it has not been sufficiently organized from the perspective of YY. This report therefore examines the challenges of XX using ZZ as a point of reference. It first organizes ZZ, then analyzes YY, and finally discusses future issues."
| Order | Function of the sentence | Example |
|---|---|---|
| 1 | Present the background. | In recent years, XX has attracted attention. |
| 2 | Present the problem. | However, issues remain regarding YY. |
| 3 | State the purpose. | This report examines ZZ. |
| 4 | Present the structure. | The discussion proceeds first, next, and finally. |
Opening examples
Opening examples should be adapted to the assignment. The following are patterns only; do not submit them unchanged. Revise them to fit your own topic, course content, and source materials.
A form such as "This report examines the issue from the perspective of YY based on course content concerning XX. It first organizes the basic characteristics of XX, then reviews previous studies on ZZ, and finally considers future issues from the perspective of YY" can be adapted to many argumentative reports.
| Assignment type | Useful opening |
|---|---|
| Explanatory | This report organizes the characteristics of XX and explains its significance. |
| Comparative | This report compares XX and YY and examines the differences between them. |
| Argumentative | This report addresses the question of XX from the perspective of ZZ. |
| Analytical or reflective | This report considers the challenges and potential of XX on the basis of the materials provided. |
Poor examples and how to revise them
Weak introductions often begin only with personal impressions, contain overly long general background, lack a clear question, or fail to show the flow of the main text. A university report should allow the reader to understand the purpose of the discussion.
For example, "I became interested in this topic and wanted to investigate it" is weak as academic problem awareness. A statement such as "In light of the course content on XX, the point YY remains open to examination" makes the connection to the assignment clearer.
| Poor example | Problem | How to revise |
|---|---|---|
| XX has always been important. | The statement is too broad and general. | Connect it to course content or the assignment prompt. |
| I am interested in XX. | It ends with personal interest. | Explain why it should be examined academically. |
| I will write about XX. | The purpose is vague. | State what will be clarified. |
| The conclusion is stated too strongly in advance. | This can make the body discussion appear unnecessary. | Present it instead as a provisional direction or expectation. |
Approximate length
The length of an introduction depends on the overall report length. As one rough guide, an approximately 2,000-character report may use about 200-300 characters, while a report of 4,000 characters or more may use about 400-600 characters. If the course provides a specific requirement, follow that instead.
If the introduction is too short, the problem awareness may not be communicated; if it is too long, it may become verbose before the main discussion begins. Keep background information to the minimum necessary and focus on what the body will actually address.
| Overall length | Suggested introduction length | Points of caution |
|---|---|---|
| 1,200-2,000 characters | About 150-300 characters | Do not broaden the background too much. |
| 3,000-4,000 characters | About 300-500 characters | State the purpose and structure explicitly. |
| Undergraduate thesis or other long-form work | Organize it as a full introductory chapter. | Link it to the research background, purpose, and methods. |
Pre-submission checks
After completing the report, check whether the purpose stated in the introduction corresponds to the answer stated in the conclusion. If the introduction and conclusion do not align, the focus may have shifted somewhere in the body.
Also check whether the points announced with wording such as "This report will..." are actually covered in the main text. If promised content is missing, revise the introduction or add the missing material to the body.
| ConfirmItem | Checklist content |
|---|---|
| Topic | Is it clear what will be discussed? |
| Problem awareness | Is the reason for addressing the issue explained? |
| purpose | Is what the report aims to clarify stated? |
| Structure | Is the flow of the body presented? |
| Alignment with the conclusion | Does it correspond to the final conclusion? |

Summary | Write the introduction using background, problem awareness, purpose, and structure
The introduction is the entrance to the report and should present the background, problem awareness, purpose, and structure. Do not begin only with personal impressions or broad generalities; make the direction for answering the assignment clear.
If you are unsure how to begin, write one sentence each for the background, problem, purpose, and structure. This usually produces a readable introduction.

FAQ
What should I write in the introduction of a report?
Briefly state the background, problem awareness, purpose, and structure. The goal is to tell the reader what the body will discuss.
Can I include the conclusion in the introduction?
You do not need to present the full conclusion at length, but briefly indicating the direction or expected line of argument can be useful.
Can I begin with a personal reaction?
This depends on the assignment, but a university report is generally weak if it begins and ends with personal impressions alone. Connect the reaction to course content or literature and formulate an academic problem.
How long should the introduction be?
It depends on the overall length. For a report of about 2,000 characters, roughly 200-300 characters is one guide, but always give priority to the submission requirements.
