Supervision of students and practitioners has been important to social work since its earliest evolution as a recognized profession. Central to the process is the idea of one professional with more knowledge, skill, and experience guiding the practice and development of another with less. The four content areas of supervision usually include direct practice, professional impact, job management, and continued learning. There are a number of supervision models, and most emphasize a positive supervisor–supervisee working relationship, a parallel process, and the importance of cultural competency. The emergence of Evidence-Based Practices and Trauma-Informed Practices has also influenced supervision. The contemporary context of social work supervision offers both opportunities and challenges to clinical supervision.
