This annotated bibliography contains summaries of research studies examining a number of College Board assessments and programs. To be included in the bibliography, each study needed to meet a number of criteria. First, articles must have been published (as a College Board research report, in an external journal, or as an ETS research report). Conference presentations or proceedings were not included because these materials often do not undergo as much scientific scrutiny as fully published papers. Also, the articles must represent research as either a validity study or an impact/evaluation study. All SAT® studies must have used samples from 2005 or later to account for the new test design, and Advanced Placement Program® (AP®) studies should have been published in the last 20 years. In addition, all studies included in the bibliography must have met at least a moderate level of scientific evidence, as defined by the U.S. Department of Education's Institute for Education Sciences. This definition includes well-designed, quasi-experimental studies and correlational designs that control for selection bias such as prior achievement levels. All studies are grouped by assessment/program, and key findings that represent a synthesis across the studies are presented. Key findings refer to results of the most rigorous work to date regarding the College Board program in question. The strength of the research design and validity of the findings vary according to the program in question, and are discussed in more detail in the summaries in this report. Many additional research studies were reviewed for the various programs, but those that did not meet these criteria were not included in this bibliography
