RadExam: Testing Platform and New Social Media

Most radiology trainees take a RadExam assessment at the end of every rotation. Exam questions cover all subspecialties, physics, and noninterpretive skills. Each subspecialty examination contains up to 35 questions. Additionally, “pre-call” exams (30 or 100 questions) are available to R1 residents and a RECR3ATE exam (340 questions) is available for R3 residents to assess performance-readiness prior to a high-stakes board examination.

AIRP® principals created a dedicated 50-question exam to assess resident content mastery after AIRP course attendance. This platform is not meant to be a rotation requirement for you to check a box; instead, it is a joint effort of the ACR® and the Association of Program Directors in Radiology (APDR) to foster resident learning.

These organizations are committed to forging excellent questions that contribute to your learning. Questions are edited first by subspecialty experts to ensure accuracy and relevance, then by more senior editors for psychometrics, and finally by one of the chief editors. The subspecialty section editors provide final question approval. This process culminates in each question undergoing four distinct levels of peer review.

The testing platform results allow program directors to assess overall educational effectiveness, subspecialty curricula, and individual resident performance and progress. Furthermore, it allows residents to meet self-study requirements prior to ACGME accreditation visits. The platform results also show strengths and areas that achieved improvement as well as areas with persistent need of improvement1.

RadExam just launched its social media presence in March 2022 via the ACR Twitter and Instagram accounts and the hashtag #RadExam. We intend to share tips and tricks to help trainees make the most of the exam platform. Additionally, we will share interesting cases as polls and later provide answers with explanations in order to contribute to free, open-access radiology education (#FOAMrad).

We also launched the RadExam community on the ACR Engage platform. The goal is to interact with you, answer your questions, receive your feedback and participate in your learning through this social media platform.
