Initial Requirements FoR Earning ARRT Credentials

Earning ARRT certification and registration is challenging, yet very achievable. It will take time and commitment—but your hard work will pay off. With an ARRT credential, you’ll have confidence that you're providing high levels of patient care. You’ll be proud of your accomplishments and the level at which you can perform. Employers and patients take note, too—your ARRT credential confirms your qualifications.  

In order to earn ARRT certification and registration, you'll need to meet our three requirements (education, ethics, and examination). Before you get started, you'll need to identify the eligibility pathway you'll use and the discipline in which you'd like to earn a credential. 

Primary Eligibility Pathway Requirements

The primary pathway is how the majority of people earn their first ARRT credential. It includes completing an ARRT-approved educational program. You can earn credentials in the following disciplines using this pathway:

  Magnetic Resonance Imaging*
  Nuclear Medicine Technology
  Radiation Therapy


The postprimary pathway is for those are currently certified and registered with ARRT and would like to pursue an additional credential. The postprimary pathway may also be used by those who hold a credential from ARDMS or NMTCB. 

  Bone Densitometry
  Breast Sonography
  Cardiac Interventional Radiography
  Computed Tomography
  Magnetic Resonance Imaging*
  Vascular Interventional Radiography
  Vascular Sonography


  Registered Radiologist Assistant

*You can earn an MRI credential using the primary or postprimary eligibility pathways

**After Dec. 31, 2019, ARRT will offer only the Primary Eligibility Pathway for earning a Sonography credential. If you still want to use the Postprimary Eligibility Pathway to earn a Sonography credential, you’ll have to meet certain deadlines. Learn more here.
