To identify the lessons learned from contracting with private managers in Philadelphia from 2002 to 2005, the author conducted an extensive document review and interviewed state, district and EMO personnel involved with the restructuring process and the specific management structure implemented to administer the Partnership School Model in Philadelphia. This brief summarizes a case study of the Partnership School Model. The full report and similar case studies of school restructuring in Baltimore City Public Schools and Chester Upland School District published by the Education Commission of the States (ECS) provide additional insights and are available on the ECS Web site.
