Codes of ethics must undergo periodic revision to ensure that the contents of the code reflect current trends and issues in counseling practice. This chapter provides a brief overview of some of the more common ethical and legal terms counselors may encounter in ethical complaints. Often one of the most confusing concepts for counselors is credentialing. A credential simply indicates that a counselor’s education and experience have been reviewed by a professional or legal body, and he or she can legitimately hold himself or herself out as a professional possessing specific knowledge and skills that meet the minimum standards of the profession. The chapter discusses professional ethics committees and state licensure boards. It also explains the court system briefly as it applies to ethical complaints in counseling. There are four legal entities that regulate the practice of counseling: professional ethics committees; state licensure boards; criminal courts; and civil courts.
