To obtain the RDMS credential, you must meet the required examination prerequisites and pass two comprehensive examinations — the physics examination and a corresponding specialty examination.
Physics Examination: Sonography Principles and Instrumentation (SPI)
• Abdomen (AB) – Available on demand
• Breast (BR) – Available on demand
• Fetal Echocardiography (FE) – Available at select times
• Obstetrics & Gynecology (OB/GYN) – Available on demand
• Pediatric Sonography (PS) – Available at select times
Note: You may pursue the FE specialty under the RDMS or RDCS credential, but once you earn the designated credential, it cannot be switched.
