Becoming an Ultrasound Technician in Tennessee - TN

How to Become an Ultrasound Technician/Diagnostic Medical Sonographer in Tennessee

At this time, there are only two states that require certification/licensing in ultrasound technology.  Tennessee is a state that does not require additional certification/licensing in this occupation.  In order to be a competitive candidate though, employers prefer ultrasound technicians registered with a credentialing organization, such as the American Registry for Diagnostic Medical Sonography (ARDMS).  Employers in Tennessee also prefer job applicants with sonography training through an accredited program.  After becoming registered with the ARDMS, individuals are now able to use the Registered Diagnostic Medical Sonographer (RDMS) credential.  The following describes the necessary steps in order to earn the RDMS credential. 


  1. In order to take the ARDMS examination, one must comply with all required prerequisites.  The ARDMS website has a prerequisite path reference guide to aid in this process.  Prerequisites include education, clinical ultrasound/vascular experience, and correlating documentation.  The ARDMS currently has 9 prerequisite paths.  The following scenario is one example. 
  • Graduation from patient-care related two-year allied health education program.
  • 12 months of clinical/vascular experience.
  • Educational transcript.
  • A copy of the official education certificate, credential, or license.
  • Original letter from the educational program director indicating completion of the clinical/vascular experience with dates.
  • Original signed and completed clinical verification (CV) form for each specialty area.
  1. Pay the application fee, which is $200 at this time.  Fully complete the online application.
  2. Successfully pass two examinations.  First, the Sonography Principles and Instrumentation (SPI) examination.  This exam consists of 120 multiple-choice questions and is two hours in length.  Second, select at least one specialty examination, which includes abdomen, breast, fetal echocardiography, neurosonology, and obstetrics and gynecology.  These exams vary in length and number of multiple-choice questions.  Practice exams are available at the ARDMS website to aid in the examination preparation process.
  3. In order to maintain an active status, an annual renewal fee of $60 is required.
  4. Completion of the above steps will assist you in marketing yourself as a professional ultrasound technician/diagnostic medical sonographer.
