Cultural competence is an ethical imperative.
"Cultural competence is an ethical issue that represents the intentional effort of the evaluation team to produce work that is valid, honest, respectful of stakeholders, and considerate of the general public welfare. Culturally competent evaluation emerges from an ethical commitment to fairness and equity for stakeholders".-From the "American Evaluation Association’s Diversity Committee"-
These concepts apply to all evaluations. However, because this statement was written for a U.S. audience, care should be used in employing these guidelines outside the United States.
