In medical education, where law and ethics are often taught simultaneously, a hidden or silent curriculum emerges strongly from research-based and descriptive reviews of practice experienced by students and qualified practitioners. In social work education, where law and ethics are more commonly taught separately, specific reference to such a curriculum does not emerge from the literature. However, evidence from reviews of social work practice points to instances of ethical and legal erosion in the context of a profession which asserts its location as a moral activity and its commitment to human rights and social justice. The purpose of this article is not to systematically compare what students may be learning in and about medicine and social work. Rather, prompted by concerns expressed in medical education research, it reviews the social work evidence and why it achieves a lower profile than parallel experiences in medicine. It explores the problems encountered in practice by students and qualified social workers when drawing on their legal and ethical knowledge. It reviews the impacts of legal and values education on social work programmes. It concludes by questioning whether the initiatives to improve social work, in England specifically, by the Social Work Task Force and Social Work Reform Board are appropriately configured to address the tensions that divide recommended from actual practice.
