Is spiritual diversity a neglected dimension in preparation for multicultural competency? The authors present an interdisciplinary overview of research related to multicultural training in spirituality and religion to address this issue. Findings indicate that counseling program leaders have minimal preparation in spiritual and religious diversity and interventions. In addition, spiritual and religious themes appear to be minimally included in counseling program curricula. Some evidence also indicates that religious and spiritual diversity is not considered as important in multicultural training as are other kinds of diversity. A movement to include spirituality and religious content in accreditation guidelines, however, points to a possible shift to expand preparation for religious and spiritual competency. The article concludes with implications for counselor preparation and supervision.
