Internal evaluators encounter risks but also significant opportunities to strengthen organizational and professional ethics. Potential contributions depend, in part, on the conjunction of ethics and evaluation in the role of the internal evaluator as the person specially commissioned to investigate value and render judgment based on evidence gathered. At the same time, risks increase when evaluation and ethics are brought together. In the words of one evaluator, “These are rather dangerous moments because a lot of energy is created when an evaluator expresses ethical values such as these. We have a great deal of power, whether we like to think so or not” (Jennifer Cartland, 2010). This article clarifies the risks in order to free up the potential. #TheoriesofEvaluation #InternalEvaluation #EvaluationEthics #2011Conference
