Professional preparation programs require trainees to participate in firsthand clinical training consisting of practica and internship field experiences. The seminal Multicultural Counseling Competencies and Multicultural Counseling and Social Justice Competencies have provided an important direction for trainees, clinicians, and supervisors to operate from as it relates to fostering and implementing multicultural knowledge, skills, awareness, and action into practice. However, literature has alluded to gaps in the application of these multicultural competencies as well as disability competencies within clinical settings. These authors will further expand upon such observations as it relates to supervision—particularly when supervising supervisees with disabilities. This chapter will explore clinical supervision best practices across allied mental health professions and will place focus on areas of improvement related to the application of multicultural counseling competencies and disability competencies to best meet the needs of supervisees with disabilities.
