From the moment evaluators begin the consultation process to the time when they respond to the last reaction to the evaluation report, ethical choices are being made. This thoughtful book explores a set of principles which can serve as foundational guidelines for making ethical decisions. Using vignettes, the authors provide ethical dilemmas and questions to stimulate thinking about the positive and negative consequences of each option. After an introduction to ethical theories and principles, a framework is proposed that can be used in weighing these options. The book concludes with suggestions for ways in which evaluators can make informed ethical decisions.From the moment evaluators begin the consultation process to the time when they respond to the last reaction to the evaluation report, ethical choices are being made.
