If you are not a physician but are interested in applying for the ARDMS RDMS credential with an OB/GYN specialty, please visit the OB/GYN specialty page on the ARDMS website.
The Obstetrics and Gynecology (OB/GYN) examination tests basic obstetrics and gynecology knowledge and skills essential to sonographer-level professionals.
As a physician, you are eligible to take many of the examinations offered by the APCA companion council, ARDMS. While ARDMS manages the OB/GYN examination and the associated Registered Diagnostic Medical Sonographer (RDMS) certification, APCA, its companion council created exclusively to serve physicians, will be your destination to apply, prepare for, schedule and maintain all your certifications. You will log into MY APCA for information regarding the examination and to apply online.
To earn the ARDMS Registered Diagnostic Medical Sonographer (RDMS) certification with an OB/GYN specialty, you must pass the Sonography Principles & Instrumentation (SPI) examination and the OB/GYN examination within five years. After passing the SPI examination, you can earn additional ARDMS certifications without having to retake the SPI examination, provided you maintain active status.
You must wait 60 days before you can retake the OB/GYN examination if you do not pass it however, you are welcome to reapply after 3 days.
