ARDMS SPI Exam exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The Inteleos SPI page lists approximately 110 multiple-choice questions in two hours, plus a five-minute survey, and the portal mock uses the same 110 questions and 120 minutes. Results are reported on a scaled score from 300 to 700, and a score of 555 or better passes; the result is not percentage-based and is not curved. The SPI Content Outline version 24.1 lists five domains with these shares of the exam: Perform Ultrasound Examinations 23 percent, Manage Ultrasound Transducers 7, Optimize Sonographic Images 26, Apply Doppler Concepts 34 and Provide Clinical Safety and Quality Assurance 10. ARDMS sets the passing score at 555 on a 300 to 700 scale. It is not a percentage of questions correct and it is not curved, so the portal mock shows a percent score only as a rough self-check. The Inteleos SPI exam page lists an exam fee of $275 USD; confirm the current amount and the fee schedule on the ARDMS or Inteleos site before you apply. The content outline spreads questions across 5 areas; the largest are Apply Doppler Concepts (34.0%); Optimize Sonographic Images (26.0%); Perform Ultrasound Examinations (23.0%). The full list of areas and weights is on the portal exam page. Set by ARDMS: the SPI exam has its own prerequisites, listed on the ARDMS prerequisites page, and you apply through your Inteleos account.
