Sonography Entrance Practice Exam 2026 – Complete Prep Guide

The American Registry for Diagnostic Medical Sonography (ARDMS) is the primary certifying body for sonographers in the United States. It is responsible for establishing the certification standards that ensure sonographers have the necessary knowledge and skills to perform their duties safely and effectively. The ARDMS offers various certification exams, such as the Registered Diagnostic Medical Sonographer (RDMS), which test candidates on their understanding of ultrasound principles and practices, anatomy, and pathology.

Certification from the ARDMS is recognized nationally and is often a requirement for employment in many healthcare facilities, as it signifies that the sonographer has met the competencies required in the field. Additionally, maintaining certification through continued education is essential for ensuring that sonographers remain current with technological advancements and best practices in sonography.

In contrast, the other organizations mentioned do not primarily focus on certifying sonographers. The American Medical Association (AMA) is a national organization that advocates for physicians and medical practices. The National Board of Medical Examiners (NBME) primarily provides assessments for medical licensing candidates and does not focus on sonography. Lastly, the American Institute of Ultrasound in Medicine (AIUM) is dedicated to education and standards for ultrasound but does not provide certification for sonographers.
