SPI Registry Review & Prep


SPI Registry Review & Prep

The Sonography Principles & Instrumentation (SPI) examination is administered in conjunction with various specialty exams by the American Registry for Diagnostic Medical Sonography (ARDMS) to certify the continuing competency of ultrasound professionals. Prospective technologists must successfully pass the SPI exam in conjunction with any specialty exam to earn their Registered Diagnostic Medical Sonographer (RDMS) credential. The SPI and corresponding specialty exam can be taken in any order, as long as both are passed within a five-year period.

The LIVE online SPI registry review and preparation course will be scheduled 1 day a week, 3 hours per day, for a duration of 10 weeks, making this an effective way to review and prepare for the examination without an overload of information to absorb. The course material will break down physics into clear concepts, interesting descriptions, helpful discussions and useful analogies. This course has been created not only to help sonographers pass the exam but to provide a solid foundation of physics which elevates competence in the field. The course content has been developed from the ARDMS content outline for the SPI exam.

Upon successful completion of the SPI review course, students will have an understanding of:
