Five-Year Rule

​​​​​​​​​​​​​​​​Candidates must pass the Sonography Principles & Instrumentation (SPI) examination and the corresponding specialty ​examination within five years, regardless of sequence. Candidates who do not complete both exams within five years must retake the examination previously passed. Candidates who passed the now-unavailable UPI, CPI or VPI examination(s) are required to pass the SPI examination if the five-year period lapses. The five-year rule does not apply to Certificants​ seeking additional specialties under a credential already earned.

The five-year rule is based on the calendar year (January 1 through December 31). The five-year period begins the day the first examination is passed, and it includes any time that remains in that year plus the next five years. For example, a candidate who passed the first ARDMS examination on June 6, 2010, is required to pass the second examination by December 31, 2015.​
