Abstract: Translational research and the training of translational researchers have generated significant attention in the past ten years. This attention has led to an emergence of a number of training programs specifically devoted to recruiting and training translational researchers. Translational training programs emphasis on team science, focus on interdisciplinary research, and acceptance of a range of career trajectories all present unique challenges to program evaluation and the development of evaluation metrics. This presentation describes the evaluation of pre-doctoral and postdoctoral Clinical & Translational Science training programs and the Howard Hughes Medical Institute’s -Integrating Medicine into Basic Science training program at the University of California, Davis. We will share the mixed methods evaluation toolkit that we developed for these programs as well as describe some of the challenges of evaluating translational training programs. #MixedMethodsEvaluation #2010Conference
