Title II of the Workforce Innovation and Opportunity Act of 2014 directs the federal government to conduct a national assessment of adult education, including activities to understand the extent to which adult education strategies positively affect learners. A systematic review of the research on the effectiveness of particular strategies in adult education is one way in which the U.S. Department of Education is fulfilling this need. This report contains the appendices to the snapshot systematic review report "Adult Education Strategies: Identifying and Building Evidence of Effectiveness. Study Snapshot. NCEE 2021-007" (ED612197). The following appendices are included: (1) Details of the Approach to Conducting the Adult Education Strategies Evidence Review; and (2) Details of Reviewed Studies. The first appendix contains the technical details of the approach followed for the systematic evidence review of research on the effectiveness of strategies in adult education. It includes more information about the organizing framework for the review and describes the process for defining its scope, identifying relevant literature, screening references and reviewing studies, and summarizing and reporting on findings. Details are provided so that someone familiar with systematic evidence reviews can understand the approach that was used and how it draws on the approach specified by the Institute of Education Sciences' What Works Clearinghouse (WWC). Some technical terms are explained throughout for readers less familiar with the WWC or research design. Exhibit A.1 presents an overview of the approach, followed by a more detailed and technical presentation of how the review was conducted. The second appendix contains information about the studies that were reviewed, which are those studies that made it through the screening process. References are included for each of the 54 studies that were reviewed, along with the WWC rating each study received and the reason for the rating. For the 22 studies that met WWC standards, summaries about the strategies tested and technical details of the study design are also provided. While some technical terms are defined in Exhibit B.1 this appendix was written for an audience with familiarity in research design.
