ACKNOWLEDGMENTS

First and foremost, we extend our thanks to the students, teachers, and school administrators who welcomed the research team into their classrooms. Without their cooperation, this study would not have been possible.

David Finegold and Paul Koegel of RAND provided insightful and (happily) congruent reviews that greatly improved our earlier drafts. Gerald Hayward of NCRVE also provided helpful and supportive comments. Donna White provided able secretarial assistance throughout the project and helped prepare the manuscript for publication.

We thank all of these individuals for their assistance but retain full responsibility for the analysis and conclusions reported here.
