This research evaluates a prostitution offender program (commonly called a "johns'" school") located in a large Midwestern city. I evaluate the components of the program, its philosophy, the short- and long-term effectiveness of the program, and its implementation to determine whether it is effective in deterring men from hiring prostitutes. By comparing pre- and post-test attitudinal forms and participants' assessment of the effectiveness of the program, I have determined that this program is effective in changing the attitudes of men that attend the program, but there are several improvements that the program organizers could implement to increase its effectiveness.
