DXIT™ and TXIT™ In-Training Exams

In keeping with the commitment to serve our Members-in-Training and their highly respected residency programs, the ACR is now offering your residents the option for remote, virtual, in-training testing for DXIT™ and TXIT™. Both of the in-training exams will be offered online using the Prometric ProProctor virtual procotoring service to provide secure procotored exams with 3rd party psychometric evaluation for accurate bench-marking.

Fulfill your training program ACGME requirements for summative assessment using the DXIT and TXIT In-Training Exams:

Evaluate your program and residents

  • Evaluate your program using national benchmarking with over 280 national and international training programs participating
    in DXIT and TXIT.
  • Benchmark individual resident scores for all residency levels.

Identify areas of deficiency

  • Offer residents an opportunity to evaluate their knowledge and to identify areas of deficiency relative to peers at the
    same level of training.

Provide secure and accurate evaluations

  • Use third-party psychometric evaluation of data for optimally accurate benchmarking. 
  • Ensure secure test data via proctored testing.
  • Prevent question sharing with new exams created each year through use of multiple equalized forms.

Prepare for exam and remediation

Count on over 30 years of experience

  • Trust in an exam existing for over 30 years
  • Created by esteemed experts in the radiology subspecialties.



The exams are scheduled annually in January (DXIT) and March (TXIT) to first- through fourth-year residents, as well as those in fellowships.

Sets of exam items, keys, annotated references and rationales are available on this page for a limited period of time. These items and keys can be used in an instructional manner, such as in follow-up discussions or meetings with residents regarding their assessments.

in the Annual Training Program Update (ATPU) System.  Be sure to report all new residents and any transfers; the names of graduates will be removed in January. Please email membership@acr.org or atpu@acr.org should you have any questions about the ATPU System.
