Which of the following is a criterion of professional standards?

• A. Unique body of knowledge
• B. Autonomy
• C. Certification and accreditation (CALEA)
• D. Ethics

Answer: (A)

Professional standards are defined by a unique body of knowledge that specifies what professionals in a field must know and be able to do. This specialized knowledge base sets the expectations for training, competency, and ongoing education, and it provides the foundation for evaluating performance and guiding credentialing. Autonomy describes how independently a professional might work, but it isn’t the defining criterion of the standard itself. Certification and accreditation, such as CALEA, are external recognition or verification processes that reflect adherence to standards rather than the fundamental criterion that defines a profession. Ethics is central to professional behavior and serves as a guiding principle, but the defining criterion that characterizes a profession is the presence of a unique body of knowledge.
