What is the ARDMS five-year rule?
Candidates must pass a principles and instrumentation 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 Registrants seeking additional specialties under a credential already earned.
