Supervision provides student development professionals with an important forum for examining and discussing ethical issues which arise in practice. However, high-quality counseling supervision may not always be available to practitioners when they need it most. Peer supervision is a method of counseling supervision which can be a viable alternative to traditional methods of supervision. Through peer supervision, student development professionals can work together to share a supervision arrangement with one or two of their colleagues without benefit of an "expert" supervisor. Regular peer supervision sessions can provide participants with important opportunities to obtain critical feedback on their work and to apply ethical standards to the realities of professional practice. This paper discusses the implications of supervision for ethical practice, the function of supervision, and the rationale for peer supervision. Models of peer supervision are presented, including the Triadic Peer Supervision Model and the Structured Peer Supervision Model. Potential benefits of peer supervision to student development professionals are listed. It is concluded that, through peer supervision experiences, student affairs practitioners can assist one another to identify, confront, and resolve ethical issues and conflicts on college and university campuses.
