ARDMS OB/GYN Exam exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The Inteleos page for the OB/GYN exam describes about 170 questions over three hours. The ARDMS OB/GYN content outline (version 24.1) has five areas: Gynecology - Pelvic Anatomy and Physiology (19%), Obstetrics - First Trimester (12%), Obstetrics - Second/Third Trimester (37%), Protocols and Procedures (24%) and Physics and Instrumentation (8%). Questions are multiple choice and hotspot (mark directly on an image). ARDMS sets the passing standard with expert-judgment methods and re-evaluates it periodically; the page reviewed for this guide does not state a numeric cut score. The OB/GYN exam costs US$300 on the Inteleos exam page. ARDMS sets the passing standard with content-expert judgment and re-evaluates it about every five years. The sources used for this guide do not state a numeric cut score, so the percent score in the portal mock is only a self-check. The Inteleos page lists the OB/GYN exam at US$300. Fees can change, so confirm the current amount on the Inteleos site before you apply. The content outline spreads questions across 5 areas; the largest are Obstetrics - Second/Third Trimester (37.0%); Protocols and Procedures (24.0%); Gynecology - Pelvic Anatomy and Physiology (19.0%). The full list of areas and weights is on the portal exam page. ARDMS sets the prerequisites for each specialty exam and expects the Sonography Principles and Instrumentation (SPI) exam as well; confirm them on the Inteleos site before you apply. The portal is a practice aid built on the published content outline: it is not a copy of the exam, it does not simulate hotspot questions, and it does not predict your score.
