Registry is a form of credentialing where a private organization gives their "stamp of approval" certifying you as a practitioner having a certain set of skills, usually by satisfying educational, clinical internship, and testing criteria.
zations such as the American Registry for Diagnostic Medi-
cal Sonography (ARDMS) certify the skills and knowledge
of sonographers through credentialing, including registration.
Because registration provides an independent, objective mea-
sure of an individual’s professional standing, many employers
prefer to hire registered sonographers. Sonographers registered
by the ARDMS are Registered Diagnostic Medical Sonogra-
phers (RDMS). Registration with ARDMS requires passing a
general physical principles and instrumentation examination,
in addition to passing an exam in a specialty such as obstetric
and gynecologic sonography, abdominal sonography, or neuro-
sonography. Sonographers must complete a required number
of continuing education hours to maintain registration with the
ARDMS and to stay abreast of technological advancements re-
