In response to current federal mandates requiring selected businesses and government agencies to use plain language (PL) when reporting information to the public, this article advocates the introduction of PL principles into current business communication curricula. Despite recent PL mandates and advances, many current business textbooks and curricula omit PL principles. Students must become familiar with PL principles in their business communication courses in order to apply PL effectively in the workplace. To accomplish this goal, the author focuses on defining PL, outlining the history and recent developments of PL, and listing the resources and exercises instructors can use to incorporate PL principles into business communication courses.
