Many people worked to make this report possible. Thanks go first and foremost to the three organizations that are the subject of the study—Jewish Vocational Service–Boston (JVS–Boston), Per Scholas and Wisconsin Regional Training Partnership (WRTP). Participating in a random assignment evaluation is a challenging and risky undertaking, and the study would not have been possible without the leadership of Barbara Rosenbaum and Jerry Rubin at JVS–Boston; Plinio Ayala at Per Scholas; and Eric Parker and Earl Buford at WRTP, as well as the ongoing efforts of dozens of staff members. We are also grateful to the study participants for sharing their experiences during interviews and in focus groups.

Over the past two decades, Jack Litzenberg of the Charles Stewart Mott Foundation has done much to advance the practice and study of sectoral strategies. His decision to invest in this random assignment study, and his patience and understanding as it unfolded, is another signal of his thoughtful leadership of the field. Thanks also must go the Mott Foundation’s communications department, and Duane Elling in particular, for their support of the project.
