As part of their mission, Clinical and Translational Science Award (CTSA) hubs are charged with developing, testing, and disseminating evidence-based practices to other CTSA hubs. Over the past 7 years, the University of Wisconsin-Madison has answered this charge by implementing the facilitator training (FT) initiative for research mentors. Three elements to advance training across the CTSA hubs have been critical: (1) using an FT model to empower others to build research mentor training at their local institutions; (2) tracking implementation of training events across the CTSA hubs over time; and (3) partnering with implementation sites to build local capacity and evaluate the effectiveness and quality of training. Here we report that facilitators have been trained at 75% of CTSA hubs. These facilitators report high satisfaction with the training and increased confidence in their ability to implement mentor training, and plan to implement local mentor training. These findings demonstrate that the FT initiative can serve as a model for dissemination and implementation of other workforce development interventions across the CTSA hubs.
