This handbook provides suggestions about quality control procedures that will enable Teacher Corps project personnel to assess the effects and success of educational products, practices, and other outputs prior to dissemination. Two assessment processes are outlined. The first, review, is the collegial ongoing process for Teacher Corps project personnel to assess the effects and potential impact of innovations before dissemination. The second, validation, is the formal post-development process for Teacher Corps projects to assess the evidence of effectiveness for approval by an official panel. Guidelines and checklists for reviewing innovative products and practices are provided. The criteria used for validating an educational program are presented along with descriptions of the responsibilities of project personnel in the validating process. A format for submitting materials to a dissemination review panel is included as well as a description of panel criteria used for judging program effectiveness. (JD)
