The purpose of this technical report is to provide timely documentation of many of the short-term effects of the movements of students that occurred as part of the displacement of storm victims. The report will help guide educators and policymakers in their ongoing responses to this disaster and preparations for future events. Focusing on the Louisiana public school system, it explores the experiences of the displaced students and the effects of their movements on the state's public education system during the first academic year following the hurricanes. Specifically this report documents patterns of student movement across the state in terms of the number of moves, durations of enrollments at each site, time out of school, and the numbers of students fitting each pattern. It also reports on the effects of the displacement on schools and their students and on policies adopted in response to serving displaced students. This study was carried out between October 2005 and September 2006. It reflects the situation in Louisiana schools through the conclusion of the 2005-2006 school year. The researchers used Louisiana's student data system, the Student Information System, to obtain information about all students in the state who entered or exited a public school at any time during the 2005-06 school year as a result of the hurricanes. Principals were also surveyed about the behaviors of displaced students, steps taken to address the needs of those students, and the effects of the influx of students on school resources, staff, and programs. Following an introduction in the first chapter of the report, three other chapters are presented. Chapter Two examines the magnitude of the displacement phenomenon in the state, the movements of students among schools, and the amount of time spent out of school. Chapter Three describes methods used in the principal survey and presents additional information about the magnitude of the displacement, along with information about the experiences of displaced students, the effects of displacement on staff and resources, and steps taken to meet the needs of displaced students. Finally, Chapter Four summarizes the findings and discusses some policy implications. Appendix A details steps that were taken to process the student-movement data, and Appendix B contains a copy of the survey questions and a detailed tabulation of the responses.
