As osteopathic medical education shifts to competency-based learning, course curriculums must adapt to measure behavioral milestones in addition to traditional knowledge and technical skills. Of the core competencies, medical professionalism or lack thereof has been shown to correlate with future state disciplinary board action; therefore, early identification of poor professionalism and intervention is imperative. However, performance indicators, such as humanistic behavior and primacy of patient need, are difficult to measure in most first- and second-year medical school courses. Therefore, A.T. Still University-Kirksville College of Osteopathic Medicine developed a rubric to objectively measure professionalism within the first- and second-year osteopathic manipulative medicine curriculum. The rubric assesses such measures as timeliness and professional appearance. In the present article, the author describes the grading rubric and the methods for implementing a professionalism score within an osteopathic manipulative medicine curriculum.
