This study describes the development of the Spiritual Competency Scale, which was based on the Association for Spiritual, Ethical and Religious Values in Counseling's original Spiritual Competencies. Participants were 662 counseling students from religiously based and secular universities nationwide. Exploratory factor analysis revealed a 22-item, 6-factor solution with internal consistency. The data highlighted areas for remediation, suggested that a stand-alone spirituality in counseling course may be the most effective instructional strategy, and provided a template for revisions to the Spiritual Competencies.
