RDMS – Registered Diagnostic Medical Sonographer

The only means of obtaining the Registered Diagnostic Medical Sonographer ® (RDMS®) credential is by examination. Required examination prerequisites must be fully met before an applicant can earn an ARDMS credential. Applicants are required to pass two comprehensive examinations to earn the RDMS credential listed below.

Important Announcement About the FE Windowed Administration Testing:
Beginning Spring 2014, the Fetal Echocardiography (FE) specialty examination for the RDMS (and RDCS) credential will be administered during select times of the year at the PearsonVUE testing centers. This allows ARDMS to provide more precise scores, update test questions more quickly and enables a level of currency, quality, and innovation that would not otherwise be possible in year-round testing. Scores for each windowed examination period will be available approximately sixty (60) days after the testing period ends.

Applications are NOW OPEN through February 12, 2014 for the Spring 2014 administration. Click here to view the press release and visit the FE examination page for more information.
