Conducting scientifically rigorous evaluations of character education interventions is complex. This evaluation guide is presented as a resource primarily for project directors who are federal grantees embarking on an evaluation of a character education intervention, although it contains useful information that can benefit other education administrators who also are providing these interventions. This guide offers strategies for working with external evaluators and key stakeholders in planning and implementing a scientifically sound evaluation. The guide is organized in a logical sequence that reflects the order in which to undertake the eight basic steps of planning and implementing an evaluation. The introduction explores the federal mandate for evaluation and notes the many ways that evaluation can contribute to the improvement, recognition and sustainability of an intervention. In addition to the list of references at the end of this report, there is a list of published resources at the end of each step. This guide also provides appendices with pertinent federal regulations, sample consent letters, a checklist of evaluation activities, examples for displaying data, and a glossary of common evaluation terminology.
