ActualTestsIT issues a full refund if you take the ARDMS Sonography Principles and Instrumentation exam within 60 days of purchase and do not pass. The policy does not apply if the exam is taken within 3 days of purchase, if the exam was never actually taken, or to free materials or expired orders, and the candidate name must match the payer name. Submit a scan of your enrollment slip and the official Score Report PDF within 2 days of the exam; claims are processed within 7 days. Alternatively, exchange for two free exam products of equal value and keep your original update service. Orders arrive by email within 1 minute — contact support if nothing arrives within 2 hours.
The official ARDMS Sonography Principles and Instrumentation outline defines 5 domains. The leading three are Pulse-Echo Instrumentation (20%), Quality Assurance and Safety (20%), and Ultrasound Transducers (20%). The full list is in the topics section above, and ActualTestsIT's 208 practice questions cover each one.
Three versions of the same study materials, offering three learning modes: a printable, expert-prepared PDF with free demo download and instant access; a Desktop Test Engine for Windows with customizable simulation and timed modes that works offline; and an Online Test Engine for any browser on Windows, Mac, Android, and iOS with test history and performance review. All 208 practice questions are identical across versions. Every purchase includes 365 days of free updates, a 50% renewal discount afterward, and unlimited computer installations.
No specific prerequisite exam required; however, candidates must meet ARDMS clinical experience or educational eligibility requirements (typically completion of a diagnostic medical sonography program or specified clinical hours). Since requirements change over time, confirm the latest on the official ARDMS exam page before scheduling.
