The Use of Evaluation to Establish an Evidence Base, Lessons Learned, and Realistic Picture of Program and Policy Implementation and Sustainability: Ohio as an Exemplar for Education Transformation

This editorial introduces a special issue containing five articles that report on an evaluation of the implementation of four education transformation models within the state of Ohio. The first article presents an overview of the cross-model results, followed by four individual articles that each present a case study analysis of one of the four transformation models. The editorial highlights how this evaluation effort as a whole demonstrates the importance of rigorous evaluation approaches for examining the strategies and challenges involved in state-wide transformation evaluation efforts.
