In 2001, the National Association of Social Workers (NASW) adopted 10 discrete standards of culturally competent practice which undergird our commitment to diversity and social justice. The concept of intersectionality is newly emerging in social work, though, causing us to reflect on our current conceptualizations of cultural competence. According to this construct, in order to understand one aspect of the self, such as race, we have to understand how gender, ethnicity, sexuality, social class, and other markers influence one another. The authors present the concepts of cultural competence, social identity, and intersectionality in order to deepen our anti-oppression, social justice approach.
