ACKNOWLEDGMENTS This study was made possible by the collaboration and hard work of many individuals beyond the study authors. We appreciate the willingness of the participating districts, schools, and teachers to use the study’s curricula, and to respond to the data requests that are the basis for this report. We also appreciate the willingness of the curriculum publishers to take part in this evaluation. We benefited from useful comments of the study’s technical working group: Richard Askey, Douglas Clements, Thomas Cook, Lynn Fuchs, Tom Loveless, Kevin Miller, Donald Rock, and Hung-Hsi Wu. We thank Melissa Thomas for helping to direct all phases of the student testing and other data collection efforts, and for her contributions to the development of the survey instruments. Alejandra Lopez helped design the teacher surveys. Tom Barton, Tim Bruursema, and Kristina Rall helped design the data collection training programs and manage the data collection. Season Bedell-Boyle and Loring Funaki coordinated the large team of student testers. Mark Brinkley, Andrew Frost, and Joel Zief provided systems support, Erin Slyne programmed the computer- assisted test instruments, and Donsig Jang provided sampling support. We thank Carol Razafindrakato for his programming expertise, and Emily Sama Martin for processing the teacher-reported adherence data. Brian Gill provided useful comments on an earlier version of the report. Marjorie Mitchell and William Garrett produced the report. Last, but far from least, we thank the team of site recruiters who diligently worked to secure the study’s first cohort of participating districts and schools. The recruiters included several report authors, Alex Bogin, Larissa Campuzano, John Deke, Patricia Del Grosso, Benita Kim, Jeffrey Max, and Melissa Thomas. The Authors iii DISCLOSURE OF POTENTIAL CONFLICTS OF INTEREST The research team for this evaluation consists of a prime contractor, Mathematica Policy Research, and a main subcontractor, SRI International. Neither organization nor its key staff have financial interests that could be affected by the findings from the evaluation. None of the study’s Technical Working Group members, which were convened by the research team to provide advice on key features of the study, have financial interests that could be affected by the evaluation’s findings. v CONTENTS Chapter Page EXECUTIVE SUMMARY .......................................................................................... xvii I INTRODUCTION AND STUDY FEATURES ................................................................1 A.
