Part I Examination Blueprint

The purpose of the ABOS Part I Examination is to evaluate a candidate’s knowledge of general orthopaedics, the basic science of orthopaedics, and a candidate’s ability to use this information for problem solving in the diagnosis and treatment of patients. To this end, the subject matter of this examination is outlined in the Part I Examination Blueprint. While the Blueprint is not a complete list of all topics that will be included on the examination, it can serve as a guide to the overall outline of the examination and can be used to guide education and preparation. It is this Blueprint that is used in constructing the examination. Candidates should understand that the questions may include interpretation, use of clinical information, laboratory tests, and imaging procedures. Questions about management may require knowledge of specific operative and non-operative treatment modalities including physical therapy and rehabilitation. The number of questions on the examination varies from 320 to 330. More information about how the written examination is developed can be found here.
