This report contains seven chapters. This Introduction, is followed by Chapter 2, a discussion of methods. Chapters 3, 4, and 5 focus on, analyze, and assess research training programs geared toward each of the four research training career stages—undergraduate, graduate, postdoctoral, and junior faculty. Chapter 6 describes the perspectives of numerous NIH research training program administrators who were interviewed as part of the committee’s data-collection process. Chapter 7 synthesizes findings across the four career stage levels and concludes with specific policy recommendations for NIH. These recommendations suggest ways to enhance NIH’s minority research training programs and provide guidance to NIH for future data collection efforts designed to enhance the ability of evaluators to assess the success of these programs at regular intervals.
