Assessing professionalism is hampered by varying definitions and these definitions' lack of a clear breakdown of the elements of professionalism into aspects that can be measured. Professionalism is multidimensional, so a combination of assessment tools is required. In this study, conducted during 2007-2008, the authors aimed to match assessment tools to definable elements of professionalism and to identify gaps where professionalism elements are not well addressed by existing assessment tools.
