This guide provides a brief overview of the issues involved in the validation process. It was developed for evaluators of adult education projects, such as 310 projects. The guide is organized in three sections. The first section discusses the rationale for validation. The second section describes the characteristics of validation models. The validation processes described are the Joint Dissemintion Review Panel Process and the Identification, Validation, Dissemination process. The final section is an overview of other issues in validation, including adoption versus adaption, evaluation experience of project staff, exemplary versus promising programs, educational versus statistical significance, responsibilities of validated program staff, and costs of validation. The guide also includes references and submission guidelines for the Joint Dissemination Review Panel Process and the Identification, Validation, Dissemination Process. (KC)
