Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text.

The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
