This report summarizes the proceedings from the workshop. Following this introduction, Chapter 2 draws on the presentations from the first panel and explains why these rates are important and how they are used for policy purposes. Based on information presented during the second panel discussion, Chapter 3 discusses the decisions that must be made in calculating these rates, and Chapter 4 explores the different types of rates and their uses. An important use of dropout and completion rates is to identify which students are likely to drop out and when they are most at risk in order to implement programs and/or interventions aimed at keeping students in school. Chapter 5 draws from several of the workshop presentations and discusses the research on early indicators of dropping out as well as on building data systems that incorporate these indicators to enable early identification of at-risk students. Chapter 6 continues the discussion of database development and summarizes the presentations made by state and district representatives participating in the third panel. Chapter 7 lays out ways the data systems can be used to improve policy and practice. The committee’s conclusions and recommendations are presented at the end of each chapter and are summarized in Chapter 8. The workshop agenda appears in Appendix A, along with a list of workshop participants and guests. Biographical sketches of committee members and staff appear in Appendix B.
