This report highlights key findings from "State and Local Implementation of the "No Child Left Behind Act." Volume IV--Title I School Choice and Supplemental Educational Services: Interim Report." A key aim of the "No Child Left Behind Act of 2001" ("NCLB") is to provide additional educational options to parents of students in low-performing Title I schools, specifically the opportunities to move their child to a higher-performing school or enroll their child in supplemental educational services. The purpose of the report is to examine the implementation across the country of the Title I school choice and supplemental educational services provisions in the 2003-04 and 2004-05 school years. The report presents findings on the implementation of parental choice options from the first year of the National Longitudinal Study of "No Child Left Behind" and the Study of State Implementation of Accountability and Teacher Quality Under "No Child Left Behind." Findings in this report are based on data from state-level interviews, surveys of nationally representative samples of district officials, principals, and teachers, surveys of parents in eight districts, surveys of supplemental service providers in 16 districts, and student-level demographic and achievement data in nine districts.
