WHAT YOU'RE PREPARING FOR

The ARDMS SPI exam is a prerequisite for every ARDMS credential — RDMS, RDCS, RVT, and RMSKS. You cannot register for specialty exams until you pass it. It tests 6 specific physics domains at specific weightings. Most students underestimate how targeted you need to be with your prep.
