ABSTRACT
Personality testing has become increasingly popular in healthcare with multiple modalities and implementations. Although personality testing has been utilized to inform various facets of graduate medical education, little is known about how the Enneagram can be utilized throughout postgraduate training. This narrative review explores the use of personality testing in graduate medical education, how personality testing has been used in the workplace, what research is available showing its use in medical residencies, and the need for additional studies on the Enneagram's use in these areas. We conclude the Enneagram may serve as a valuable tool that can be used in postgraduate medical education to improve learning, interpersonal relationships, and teaming.
