In 1989, the Kentucky Supreme Court ruled that Kentucky's education system was unconstitutional and invalidated the entire body of school law. In response, the General Assembly passed the Kentucky Education Reform Act of 1990 (KERA), a completely new educational system. This report upon the 10th anniversary of KERA's passage documents how key reforms have been implemented during the past decade and what impact they are having on the education of Kentucky's children. The report has four sections. A narrative section provides profiles of a dozen Kentucky schools and how the reform initiatives have changed them. These schools vary greatly in geography and demographics and include rural and urban schools, but are all scoring well on Kentucky's core content tests and have some important characteristics in common. An implementation section describes each key element of reform and includes such data as the number of students or schools served or affected, annual funds allocated, and perceived effectiveness. The reforms include extended school services, family resource/youth services centers, financial equity among school districts, expanded preschool programs, flexible grouping in primary grades, professional development, school-based decisionmaking, and technology investment. A results section documents the impact KERA has had on school improvement and student achievement through numerous graphs. A timeline highlights major milestones in the implementation of the new system. A final section highlights areas that need improvement and poses questions concerning policy issues in these areas. (TD)
