The RMSK exam is offered by the Alliance for Physician Certification & Advancement (APCA) for professionals specializing in musculoskeletal ultrasound. It is accredited by The American National Standards Institute (ANSI) under the International Organization for Standardization (ISO) 17024 Standard. By earning the RMSK sonography certification, physicians and sonographer-level professionals can gain a critical edge in promoting themselves as preeminent musculoskeletal practitioners.

RMSK is a physician and advanced care provider level certification that requires prerequisites including holding a relevant degree and having clinical experience in ultrasound with a minimum of 150 diagnostic ultrasounds performed. The exam covers five key areas: general sonographic anatomy (26%), general sonographic pathology (23%), ultrasound-guided interventional procedures (18%), integration of data (7%), and physics and instrumentation (26%). It consists of ~200 multiple choice questions to be completed in 4 hours, with a minimum passing score set by APCA. The exam is offered in 2 one month cycles each year. The average overall pass rates over the last 8 years range from 63% - 73%.

Preparation involves studying textbooks, attending preparatory courses, and practicing with sample questions to ensure familiarity with the content and exam format. There are very few resources and study materials that exist for this exam.
