Sonography Principles & Instrumentation Examination (SPI)

​​​​​​​​The Sonography Principles & Instrumentation (S​PI) examination tests the requisite​ physical principles and instrumentation knowledge essential to sonography professionals and students.

As a physician, you are e​ligible to take many of the examinations offered by the APCA companion council, ARDMS. While ARDMS manages the SPI examination, APCA, 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 an RDMS, RDCS, and RVT certification, you must pass the SPI examination and a corresponding specialty examination within five ye​ars. After passing the SPI examination, you can earn additional certifications without having to retake the SPI examination, provided you maintain active status.

​You must wait 60 days before you can retake ​the SPI examination if you do not pass it however, you are welcome to reapply after 3 days
