The social work field of the early 1960s incorporated supervision into the professional experience of new students and recent graduates only. The author argues that supervision should be an essential component every social worker's professional life. Since social work is not an exact science, it is impossible for any practitioner to be entirely sure of her course of action; consulting with a supervisor can help practitioners navigate through each individual case that comes before them. Though some would argue that seasoned practitioners no longer need supervision, the author claims that even the most skilled social workers, through a supervisory process, can continue to grow both as supervisors and as practitioners. In this way, they can contribute to the development of both the profession and the practice of social work across the field.
