The expository essay is the genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and make a statement concerning that idea in a clear and concise manner. Generally, expository essays do not require a great deal of outside research, but they do require that a student has background knowledge of a topic.

The expository essay generally begins with a hook to get the reader's attention:

  • A question or inquiry statement to draw the reader in,
  • A quote related to the topic,
  • An amazing fact that is unique or special,
  • A statistic or fact related to the topic (a number, percent, ratio),
  • An anecdote that illustrates the topic. 

The thesis of the expository essay should be based on factual information that will be presented in the body of the essay. The thesis should be clear and concise; it generally comes at the end of the introductory paragraph. 

The expository essay may use different text structures to organize the evidence. It may use:

  • A sequence that follows a timeline or order to give readers a chronological of events or a list of steps in a procedure,
  • A comparison and contrast to show the similarities and differences between two or more people or things,
  • A description to give the reader a mental picture,
  • An example or illustration, 
  • An example of cause and effect or the relationship between an event or concept and the events or concept that follows.

An expository essay may integrate more than one text structure. For example, one body paragraph may use the text structure of description of evidence and the following paragraph may use the text structure of comparing the evidence.

The conclusion of the expository essay is more than a restating of the thesis. The conclusion should elaborate or amplify the thesis and give the reader something to ponder. The conclusion responds to the reader's question, "So what?"

Student selected topics:

Expository essay topics may be selected by a student as inquiry. The expository essay may ask for an opinion. Several of the following prompts are examples of inquiries that could be posed by a student:
