Public policy issues in professional writing may be understood, in part, by revisiting our understanding of the writing process and of the way character, or ethos, is shaped in the writing and reading of a text. This paper suggests a method for modeling the characters of writers, readers, and sponsoring organizations as they are shaped in the process of writing about public policy issues. The model is then used to examine the classroom oral presentations of four professionals who were involved in different ways with the same controversial public policy issue. The goal is to integrate classroom considerations of the writing process and of audience analysis, of personal and professional ethics, and of relevant workplace controversies.
