The purpose of this study was to analyze the findings of research studies investigating the role of instructional materials, review issues and recommendations referring to instructional materials in policy papers, and evaluate the decision-making process in relation to the development, diffusion and adoption of EdReports program. Content analysis was used to analyze the subject matter of reports and policy papers. A decision-oriented evaluation model was used to analyze planning, structuring, implementing and recycling decisions occurring in the change process within EdReports.org. The results showed that the wave of research investigating the role of materials has continued with publication of new reports, the release of policy papers, initiation of a study investigating adoption patterns, and commencement of new projects by EdReports.org. The findings showed that researchers are investigating the effects of decision-making on the selection of high-quality, standards-aligned materials, foundations and non-profit organizations are providing recommendations to policymakers to link high-quality, standards-aligned materials with professional learning, and EdReports.org has developed, diffused and adopted a program to provide information about high-quality, standards-aligned materials to the education community.
