The What Works Clearinghouse (WWC) evaluates research studies that look at the effectiveness of education programs, products, practices, and policies, which the WWC calls "interventions." Many studies of education interventions make claims about impacts on students' outcomes. Some studies have designs that enable readers to make causal…

This paper reviews literature on evaluating allegations of child sexual abuse, to determine whether there are systematic and significant differences on psychological tests between sexually abused and nonabused children, and whether these differences are a direct result of sexual abuse or a result of other coexisting factors that might cause…

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…

This letter reports on a research study in which five students (initially identified as severely mentally retarded and/or autistic) were tested with and without the use of facilitated communication while facilitators were prevented from hearing the test questions. Positive results for four of the students raise issues about accurate educational…

This paper discusses the practice of social validity assessment in applied behavior analysis, proposes elements that should be included in state-of-the art assessment procedures, offers a taxonomy of consumers to guide the construction and circulation of assessments, and suggests strategies to improve social validity assessment.

The second of two related pamphlets, this guide describes how to design an outcome study and outlines procedures for collecting outcome data. After an introduction that delineates the purpose of the two-part series, the pamphlet is divided into four major sections. The first section explains how to select a cost-outcome analysis. The next three…

This paper argues that many social validity processes in applied behavior analysis are actually measuring consumer satisfaction and not the habilitative validity of goals, procedures, or outcomes. The term "habilitative validation" is proposed to replace social validity, and use of more objective assessment methods is encouraged.…

Three studies identifying the characteristics of program submittals approved by the Joint Dissemintion Review Panel were examined. Between 1978-1985, 358 demonstration programs were submitted. For each of these years, between 51 percent and 83 percent of the submittals were approved. In this study, the submittals were reviewed on the basis of the…

Current practice in educational program evaluation was examined through analyses of 232 reports submitted, from 1980 to 1983, by institutions seeking approval for their programs from the U.S. Department of Education's Joint Dissemination Review Panel (JDRP). The JDRP reviews these reports to determine whether educational programs have demonstrated…

This paper reports the status of the Profile of School Excellence (PRO-S/E) after three years use and the results of a second validation study. The PRO-S/E, used in over 20 school districts in six states, is a diagnostic system school districts use to determine strengths and weaknesses based on 11 characteristics of effective schools. Data is…

Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…
