BACKGROUND:A growing body of literature shows that many universities and colleges are making educational portfolios part of their faculty assessment and student's learning plan for both undergraduate and graduate programs. We provide an outline for the development of a medical educator's portfolio, including an electronic version. DESCRIPTION:Guidelines for the development of an educational portfolio focusing on medical education are provided, including design, format, and content. An electronic version of the portfolio, which combines flexibility and ease of revision, is also described, including formats for publication and distribution. Student reflections on the e-portfolio are presented, and potential applications of the e-portfolio in medical education are described. CONCLUSION:We believe that portfolio development is a valuable application that provides rich documentation of participants' educational history, accomplishments, and intellectual property as related to their professional learning and growth.
