RDMS - PS - RDMS: Pediatric Sonography (ARDMS)

The Registered Diagnostic Medical Sonographer (RDMS) certification with a specialty in Pediatric Sonography (PS) is a professional credential for sonographers specializing in the assessment and diagnosis of pediatric patients using ultrasound technology. Administered by the American Registry for Diagnostic Medical Sonography (ARDMS), this certification validates a sonographer's expertise in conducting and interpreting ultrasound examinations in infants and children. It’s designed for sonographers who aim to provide high-quality diagnostic imaging in a pediatric setting, aiding in the accurate diagnosis and treatment of various conditions.

Completion Time: 3 hours

Cost: The PS exam fee is $275, includes processing fee $100 (non-refundable). There is an additional $50 non-refundable fee if you schedule your exam outside of the United States, Canada or Mexico. The fee for the SPI exam is $250.

Exam Format

Earning the RDMS credential with PS specialty requires passing the Sonography Principles and Instrumentation (SPI) exam and the PS exam within 5 years. Both exams initially receive a Pass/Fail grade, but test takers also receive a scaled score, ranging from 300 to 700, with a score of 555 required to pass on all ARDMS exams.

The PS exam contains 170 multiple-choice questions, including hotspot questions.  Applicants have 3 hours to complete the exam. The PS exam is only offered during select periods each year, with current details available on the ARDMS site.
