A consideration of college honor codes examines why academic integrity is one of the most effective vehicles for teaching about moral responsibility, how honor codes are distinguished from codes of conduct, how students reason about academic integrity issues, the role of penalties and punishments, and steps campuses can take. A discussion of the power of honor codes for teaching students about moral responsibility notes that three conditions must be in place: universal agreement that the prohibited conduct is unacceptable by all campus constituencies; effective prevention or deterrence of the prohibited conduct; and reliable and fair measures of enforcement. Honor codes are described as characterized by a signed pledge, obligation not to tolerate and to report offenders, peer judiciary, and unproctored exams. A look at how students reason about academic integrity notes the strong influence of peers' behavior and the importance of understanding the social and cognitive constructs most prevalent at a particular institution. A discussion of penalties and punishments argues that the role of punishment as a deterrent cannot be ignored. A conclusion lists nine steps that campuses can take to enhance academic integrity and argues that efforts to restore honor to codes of conduct must focus on fostering an environment which encourages students and faculty to adopt the values of integrity.
