Supervision is a key element to the development of ethical skills and awareness in rehabilitation counselors. Ethical standards specific to rehabilitation counselor educators and supervisors were first introduced in 2002 and updated in 2010 and 2017. This article discusses supervision and professional dispositions as constructs that were used to help frame the revision process and outlines some of the key change to Section I. (Supervision, Teaching, and Training) of the Code of Professional Ethics for certified rehabilitation counselors. In conjunction with the revision process, special considerations for multicultural competencies have been strengthened throughout Section I, as well as specific requirements for the measurement and assessment of professional dispositions in educational settings. The article helps to inform and guide supervisors, trainers, and educators as they review Section I and consider their role in the development of ethical skills in those they supervise and their own respective practice.
