MedEdPORTAL is an online publication service provided at no charge by the Association of American Medical Colleges (AAMC). The intent is to promote collaboration and educational scholarship by helping educators publish and share educational resources. With MedEdPORTAL, users can quickly locate high-quality, peer-reviewed teaching materials in both the basic and clinical sciences. The existing MedEdPORTAL collection includes instructional and assessment materials to support the continuum of medical education (ie, undergraduate, graduate, and continuing medical education). The collection features resources designed to improve or enhance teaching and learning. During the past 2 years utilization of published resources and submissions to MedEdPORTAL have grown substantially. MedEdPORTAL currently averages 2 new submissions per day, with 1,000 individual submissions having been received for consideration for publication from educators representing countries around the globe. As of December 31, 2007, 45% of total submissions were accepted and published in MedEdPORTAL, 29% were accepted with revisions, and the remaining 26% were rejected and never published. More than 30 different countries access and utilize resources published and disseminated through MedEdPORTAL. The rapid growth of MedEdPORTAL suggests that it is meeting an important need for those in medical education. It is intended that MedEdPORTAL should continue to grow and eventually become the "one-stop shop" for publishing and locating high-quality, peer-reviewed educational resources that cover the continuum of medical education.
