Which best describes the function of a credentialing agency?

The function of a credentialing agency primarily involves verifying and certifying the qualifications and competencies of mental health professionals, including alcohol and drug counselors. Credentialing agencies establish standards for education, training, experience, and ethical practice to ensure that professionals meet the requirements to provide effective services to clients. This includes granting licenses, certifications, or other credentials that signify a professional's ability to practice competently and ethically in their field.

By doing so, credentialing agencies help maintain the integrity of the profession and protect the public by ensuring that only qualified individuals are providing mental health services. This plays a crucial role in upholding the standards of care and promoting professional accountability within the field.

In contrast, regulating client behavior, advocating for client rights, or developing new therapeutic practices falls outside the primary function of credentialing agencies, as these roles pertain more to advocacy groups, direct service providers, or research institutions focused on mental health advancements.
