Assessment of Reasoning Tool

Assessment of Reasoning Tool

Errors in clinical reasoning are central factors in many diagnostic errors.


Use the Assessment of Reasoning Tool (ART) to assess a learner’s clinical reasoning skills during patient presentations.


  • The ART will guide your feedback conversation with your learner and serve as formative feedback.
  • The ART can also help programs fulfill LCME and ACGME requirements for assessing diagnostic and clinical reasoning skills.
  • Download the Users Guide for information on how to use the tool during assessment.

  • View the 5 faculty development videos (about 4 minutes each) to guide your use of the ART.
