A thesis statement is a sentence (or sentences) that expresses the main ideas of your paper and answers the question or questions posed by your paper. It offers a quick and easy-to-follow summary of what the paper will be discussing and what you as a writer are setting out to tell them. The kind of thesis that your paper will have will depend on the purpose of your writing.
General Thesis Statement Tips
- A thesis statement generally consists of two parts: your topic, and then the analysis, explanation(s), or assertion(s) that you're making about the topic. The kind of thesis statement you write will depend on what kind of paper you're writing.
- In some kinds of writing, such as narratives or descriptive essays, a thesis statement is less important, but you may still want to provide some kind of statement in your first paragraph that helps to guide your reader through your paper.
- A thesis statement is a very specific statement -- it should cover only what you want to discuss in your paper, and be supported with specific evidence. The scope of your paper will be determined by the length of your paper and any other requirements that might be in place.
- Generally, a thesis statement appears at the end of the first paragraph of an essay, so that readers will have a clear idea of what to expect as they read.
- You can think of your thesis as a map or a guide both for yourself and your audience, so it might be helpful to draw a chart or picture of your ideas and how they're connected to help you get started.
- As you write and revise your paper, it's okay to change your thesis statement – sometimes you don't discover what you really want to say about a topic until you've started (or finished) writing. Just make sure that your final thesis statement accurately shows what will happen in your paper.
Analytical Thesis Statements
In an analytical paper, you are breaking down an issue or an idea into its component parts, evaluating the issue or idea, and presenting this breakdown and evaluation to your audience. An analytical thesis statement will explain what you are analyzing, the parts of your analysis, and the order in which you will be presenting your analysis.
Example: An analysis of barn owl flight behavior reveals two kinds of flight patterns: patterns related to hunting prey and patterns related to courtship.
A reader who encountered that thesis in a paper would expect an explanation of the analysis of barn owl flight behavior, and then an explanation of the two kinds of flight patterns.
Questions to consider when writing an analytical thesis statement:
- What did I analyze?
- What did I discover in my analysis?
- How can I categorize my discoveries?
- In what order should I present my discoveries?
Expository (Explanatory) Thesis Statements
In an expository paper, you are explaining something to your audience. An expository thesis statement will tell your audience:
- what you are going to explain to them
- the categories you are using to organize your explanation
- the order in which you will be presenting your categories
Example: The lifestyles of barn owls include hunting for insects and animals, building nests, and raising their young.
A reader who encountered that thesis would expect the paper to explain how barn owls hunt for insects, build nests, and raise young.
Questions to consider when writing an expository thesis statement:
- What am I trying to explain?
- How can I categorize my explanation into different parts?
- In what order should I present the different parts of my explanation?
Argumentative Thesis Statements
In an argumentative paper, you are making a claim about a topic and justifying this claim with reasons and evidence. This claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. However, this claim must be a statement that people could possibly disagree with, because the goal of your paper is to convince your audience that your claim is true based on your presentation of your reasons and evidence. An argumentative thesis statement will tell your audience:
- your claim or assertion
- the reasons/evidence that support this claim
- the order in which you will be presenting your reasons and evidence
Example: Barn owls' nests should not be eliminated from barns because barn owls help farmers by eliminating insect and rodent pests.
A reader who encountered this thesis would expect to be presented with an argument and evidence that farmers should not get rid of barn owls when they find them nesting in their barns.
Questions to consider when writing an argumentative thesis statement:
- What is my claim or assertion?
- What are the reasons I have to support my claim or assertion?
- In what order should I present my reasons?
* Remember that a good thesis statement in any type of paper takes a stand and is specific. Avoid vague language or simply stating an obvious fact. For example, you would not want your thesis to be: "Barn owls live in barns."

Tips for Writing Your Thesis Statement
1. Determine what kind of paper you are writing:
- An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
- An expository (explanatory) paper explains something to the audience.
- An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.
If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.
2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.
3. The thesis statement usually appears at the end of the first paragraph of a paper.
4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.
Thesis Statement Examples
Example of an analytical thesis statement:
An analysis of the college admission process reveals one challenge facing counselors: accepting students with high test scores or students with strong extracurricular backgrounds.
The paper that follows should:
- Explain the analysis of the college admission process
- Explain the challenge facing admissions counselors
Example of an expository (explanatory) thesis statement:
The life of the typical college student is characterized by time spent studying, attending class, and socializing with peers.
The paper that follows should:
- Explain how students spend their time studying, attending class, and socializing with peers
Example of an argumentative thesis statement:
High school graduates should be required to take a year off to pursue community service projects before entering college in order to increase their maturity and global awareness.
The paper that follows should:
- Present an argument and give evidence to support the claim that students should pursue community projects before entering college
