It is typically a voluntary credential that goes beyond a state-issued license. It demonstrates a professional’s expertise and credibility in specific, specialized procedures. National certifications often require passing a rigorous exam and, in some cases, documenting a certain number of procedures performed under supervision. These certifications can make it easier for professionals to transfer their skills and qualifications to other states that recognize the credential.
