Abstract
The American Registry for Diagnostic Medical Sonographers (ARDMS) administers credentialing examinations for individuals in specialties in medical sonography and vascular technology. The ARDMS is a member of the National Commission of Certifying Agencies, which accredits certifying organizations, as well as being accredited by the American National Standards Institute (ANSI) and the International Standards Organization (ISO). Part of the requirement of the certifying agencies is that the examinations reflect current practices in each of the specialty areas. To fulfill this requirement, the ARDMS performs a task analysis of each specialty examination every five years. The survey covers each content area of the certifying examination and the content outline is revised to reflect any changes in the current practice of the specialty. The examination blueprint is the revised outline which ARDMS provides for their OB/GYN examination candidates. (See appendix at the end of this article.)
