The two-year Robert A. Winn Diversity in Clinical Trials: Community-oriented Clinical Trialist Training (Winn COCT Training) will be delivered in a variety of formats (e.g., didactic lectures, practical workshops, expert panels, and roundtable community discussions). Additionally, it will provide comprehensive training in clinical research design, funding, and implementation, and in trauma-informed community engagement methods and strategies. An intensive six-day training in clinical research, designed and hosted by the American Association for Cancer Research (AACR), will precede and set the foundation for the Winn COCT Training.
