It is important that counsellors provide evidence regarding the efficacy of their services. Although there has been an increased focus on generic outcome measurement of counselling programs and services, little attention has been paid to accountability issues for meeting the needs of diverse populations. This article highlights the increasing relevance of cultural diversity for evaluation practices, using examples from the Canadian context. An overview is provided of the key issues for evaluation of programs and services involving culturally diverse individuals and how evaluation must incorporate social justice issues within service provision. Evaluation strategies are elaborated along with suggestions for enhancing the intercultural competence of evaluation personnel.
