Ultrasound Technician Certification

Getting Certified in Diagnostic Medical Sonography

certification is a license or credential that you earn to show that you have specific knowledge or skills. The ARDMS ® (American Registry for Diagnostic Medical Sonography) is one of the most recognized sonography license organizations across the United States and the world.

The ARDMS offers ultrasound certificates in Abdomen, Breast, Echocardiography, Neurosonology, OB/GYN, Vascular Technology, Musculoskeletal Sonography. The Commission on Accreditation of Allied Health Education Programs (CAAHEP) accredits thousands of health science education programs in the US. If you graduate from a school accredited by the CAAHEP, you’re automatically qualified to sit for the ARDMS exam. Both the ARDMS and CAAHEP will be explained in further detail below.

Ultrasound Certifications

The ARDMS is not the only organization that offers certification. Diagnostic medical sonographers can also apply for Sonography Certification through the ARRT (American Registry for Radiologic Technologists). Completing an ultrasound program from an accredited school (recognized by the CHEA or USDE) within the last five years makes you eligible to sit for the ARRT certification exam.

“I would recommend taking your certification boards soon after graduation. The information is fresh in your mind, and you will become more marketable for jobs if you have those under your belt. Get yourself out there in the job field. Even if you don’t get the perfect job to start, keep an open mind and be receptive to any opportunities that arise.” – Jessica Carlino, RDMS, RVT

To acquire and maintain this ultrasound license, candidates must also abide by the ARRT’s Rules of Ethics, which strives to promote and maintain patient welfare. Additionally, an ultrasound practice (i.e. a medical center or hospital) can become accredited through the American Institute of Ultrasound in Medicine (AIUM).

Important Things to Know about the ARDMS

How do I earn my ARDMS Certification?

ARDMS certification is achieved by passing the Sonography, Principles and Instrumentation (SPI) Exam, and is something that most graduates will pursue once they earn their ultrasound technician degree. You will also need to pass a specialty exam related to your specific field of study in order to receive a certificate.

Is ARDMS certification required?

Most states don’t require diagnostic medical sonographers to hold particular credentials, with the exception of New Hampshire, New Mexico, North Dakota and Oregon.

More recently, legislation to mandate the credentialing of ultrasound techs are being pursued by some states, while others are considering it. Additionally, many employers prefer or require serious job candidates to have an ultrasound certification.

There are additional ultrasound certification processes you can pursue to demonstrate the full range of your expertise and specialization that will allow you stand out from other job applicants.

CAAHEP – Commission on Accreditation of Allied Health Education Programs

The Commission on Accreditation of Allied Health Education Programs is responsible for the accreditation of over 2,100 postsecondary education programs across North America, 23 of which focus on health or health science.

The CAAHEP’s certification is recognized by the Council for Higher Education Accreditation (CHEA). This is key because to be eligible for the CAAHEP or other ultrasound certifications such as the ARDMS, part of the typical criteria is completion of an educational program recognized by the CHEA (or the USDOE or CMA).

Additionally, you’re automatically qualified to take the ARDMS exam if you graduate from a school accredited by the CAAHEP.

Member organizations

The CAAHEP consists of member organizations that are knowledgeable in each health science field and are able to provide valuable input related to accredited educational programs.

Among the member organizations are several related to the field of ultrasound. These include:

  • The American Institute of Ultrasound in Medicine (AIUM)
  • The American Society of Echocardiography (ASECHO)
  • The Committee on Accreditation for Advanced Cardiovascular Sonography
  • The Joint Review Committee on Education in Diagnostic Medical Sonography (JRCDMS)
  • The Society of Diagnostic Medical Sonography (SDMS)
  • The Society for Vascular Ultrasound (SVU)

In short, when selecting an ultrasound degree or certificate program, ensure it is recognized by the CHEA, USDOE or CMA. If it is accredited through the Commission on Accreditation of Allied Health Education Programs (CAAHEP), you will be meeting this particular prerequisite for the ultrasound license process.
