This report, the second in a series, was developed to give district leaders guidance as they implement supplemental services under the No Child Left Behind (NCLB) Supplemental Educational Services (SES) provision. This provision gives parents of elegible children the opportunity and the funding to choose a private tutor or other academic support provider to help their child succeed in school. The five districts profiled in this guide are Forsyth County, Georgia; Los Angeles, California; Rochester, New York; San Diego, California; and Toledo, Ohio. Their implementation experiences yield some common themes and lessons that might be helpful to others working on supplemental services. For instance, successful districts embraced the spirit of supplemental services by setting a positive tone about the importance of these provisions, planning for their implementation, and staffing the program adequately. They built strong relationships with providers, helped them access school facilities, created a fair contracting system, used multiple methods to inform parents of their options and helped them make the best choice for their children. They established clear student learning goals and ensured that providers were supplying frequent progress reports to parents and teachers. Appendices contain school district profiles, research methodology, and resource lists.
