How to Write a Good Thesis Statement

The Common Core State Standards Writing Strand includes the argumentative essay (W.1) and the informational/explanatory essay (W.2). Each genre requires a different form for its thesis statement. 

Of course, the thesis statement is dictated by the demands of the writing prompt. The writing prompt tells you what to write about and how to do so. A good thesis statement directly responds to the writing prompt. For an argumentative essay, the thesis statement states the claim(s) of the essay. For an informational/explanatory essay, the thesis statement states the specific purpose of the essay.

How to Write a Good Thesis Statement

A good thesis statement does the following:

1. It states the subject of the writing prompt.

2. It repeats the key words of the writing prompt. After all, the reader wants to be assured that you are focused on the demands of the writing task–not following your own agenda.

3. It directly responds to each part of the writing prompt with a specific purpose (for informational/explanatory essays) or point of view (for argumentative essays).

4. It justifies discussion and exploration; it doesn’t just list a topic to chat about. For example, “Whales are really big mammals” would not justify discussion or exploration.

5. It must be arguable, if the thesis introduces a argumentative essay. For example, “War is really bad and must be stopped” is not an arguable point of view.

For short essays, a good thesis statement is characterized by the following:

1. It has one or two declarative sentences (no questions).

2. It is placed at the end of the introduction. This is not a hard and fast rule; however, the thesis statement does appear in this position in fifty percent of expository writing and the typical organization of an introductory paragraph is from general to specific. Think of an upside-down pyramid.

3. It does not split the purpose or point of view of the essay into two or more points to prove. It has a single purpose or point of view that multiple topic sentences will address.

4. It may or may not include a preview of the topic sentences.

Mistakes to Avoid in a Thesis Statement

Following are the alphanumeric codes and prescriptive comments I use to comment on student thesis statements in my Essay e-Comments:

• e5 Thesis Statement In an essay that requires the writer to inform the reader, the thesis statement should state your specific purpose for writing. The thesis statement serves as the controlling idea throughout the essay.
• e6 Thesis Statement In an essay that requires the writer to convince the reader, the thesis statement should state your point of view. The thesis statement serves as the       argument or claim to be proved throughout the essay.
• e7 Thesis Statement does not respond to writing prompt. Re-read the writing prompt and dissect according to the WHO (the audience and role of the writer), the WHAT (the context of the writing topic), the HOW (the resource text title and author), and the DO (the key writing direction word).
• e8 Thesis Statement does not state the purpose of the essay. Dissect the writing prompt, focusing on the WHAT (the context of the writing topic), the HOW (the   resource text title and author), and the DO (the key writing direction word) to specifically state the purpose of your essay.
• e9 Thesis Statement does not state the point of view of the essay. Dissect the writing prompt, focusing on to the WHO (the audience and role of the writer), the HOW (the resource text title and author), and the DO (the key writing direction word) to clearly state your specific point of view.
• e10 Thesis Statement is too general. Get more specific in your thesis statement. Example: There were lots of causes to the Civil War. Revision: Although many issues contributed to problems between the North and the South, the main cause of the Civil War was slavery.
• e11 Thesis Statement is too specific. Your thesis statement needs to be a bit broader to be able to respond to the demands of the writing prompt. A good thesis statement is like an umbrella-it must cover the whole subject to be effective. Save the specificity for the body paragraphs.
• e12 Thesis Statement is inconsequential. The thesis statement must state a purpose or point of view that can be meaningfully developed in the essay.
• Example: People in France really enjoy their cheese. Revision: The French especially enjoy four types of cheeses.
• e13 Thesis Statement cannot be argued. An essay designed to convince a reader of the author’s specific point of view must provide a thesis statement that is arguable.      Example: Blue is the best color. Revision: Blue is the best color to complement a bright white background.
• e14 Split Thesis Statement Don’t write a split (divided) thesis. A split thesis includes two purposes or two points of view. Focus on only one purpose of point of view       throughout the essay. It may be necessary to reference or refute another purpose or point of view in the body paragraphs or conclusion.
• e15 Thesis Statement responds to only part of the writing prompt. Dissect the writing prompt according to the WHO (the audience and role of the writer), the WHAT (the context of the writing topic), the HOW (the resource text title and author), and the DO (the key writing direction word) and include each part.
