DXIT™ and TXIT™ In-Training Exams

The Diagnostic Radiology In-Training (DXIT™) and the Radiation Oncology In-Training (TXIT™) exams offer residents an opportunity to evaluate their knowledge and to identify areas of deficiency relative to peers at the same level of training. They also serve as useful tools for Program Directors to assess the effectiveness of their curriculum as benchmarked against other residency programs.

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

DXIT Program Directors receive sets of exam questions, keys, annotated references and rationales for a period of time. ACR recommends that these items and keys be used in an instructional manner, such as in follow-up discussions or meetings with residents regarding their assessments.

Attention Program Directors
Please update your program and resident information
in the ATPU system. Be sure to report all new residents and any transfers. Please email membership@acr.org should you have any questions about ATPU system.

Please provide full legal names of residents participating in the DXIT exam; resident name must match their valid, government-issued Identification on exam day at the Testing Center.
