You can now read the second report in the Equity Campaign's Education, Equity, and the Law series, "Substantial and Yet Not Sufficient: Kentucky's Effort to Build Proficiency for Each and Every Child." Written by Susan Perkins Weston, independent consultant working on Kentucky education issues, and Robert F. Sexton, executive director of the Prichard Committee, the report provides an analytic overview of the origins, impact and implications of Kentucky's landmark educational adequacy litigation, Rose v. Council for Better Education . It provides important new material and insights regarding the political mobilization for school reform, legislative action, statewide implementation, and recent fiscal difficulties that have occurred over the past 20 years since the case was decided. The authors make their case that Kentucky's 1989 court ruling and 1990 legislation unquestionably led to substantive improvement for all students in the state. Based on their experience, they also share a set of thoughts about what counts as successful work to build school systems that serve all students well.
