We asked five researchers (Henry Braun, Paul Holland, Daniel McCaffrey, Steve Raudenbush, and Steven Rivkin) to review these articles and assist the committee in synthesizing the results. McCaffrey and Rivkin assisted the committee by identifying additional analyses that would help clarify the results, and Harris, Sass, and Ladd conducted these studies.

We sought assistance in evaluating the psychometric qualities of the NBPTS assessment, and Teresa Russell helped with this aspect of our work. We also obtained a data set from the NBPTS and had David Perda conduct analyses that helped us understand who participates in the program and how they compare with other teachers on a national basis. Finally, we heard presentations by Carol Cohen and Jennifer King Rice, who discussed their work on estimating the costs of support programs for teachers going through the NBPTS process.
