Clearinghouses are influential repositories of information on the effectiveness of social interventions. To identify which interventions are "evidence-based," clearinghouses review intervention evaluations using published standards of evidence that focus primarily on internal validity and causal inferences. Open science practices can…

The What Works Clearinghouse (WWC) is a source that is used to report the empirical evidence for interventions. The purpose of this review was to understand the presence of Black children in research that has been classified as Meeting the Standards With and Without Reservations by the WWC. Results indicated that 16 interventions met the WWC…

The What Works Clearinghouse (WWC) seeks to provide practitioners information about "what works in education." One challenge in understanding "what works" is that effect sizes may not be comparable across studies, which limits the ability to compare the relative effectiveness of multiple interventions. One factor that…

The "Knowledge Is Power Program" ("KIPP") is a nonprofit network of more than 200 public charter schools educating early childhood, elementary, middle, and high school students. The What Works Clearinghouse (WWC) identified four studies of "KIPP" that fall within the scope of the Charter Schools topic area and meet…

In this article, we respond to Wolery's critique of the What Works Clearinghouse (WWC) pilot "Standards," which were developed by the current authors. We do so to provide additional information and clarify some points previously summarized in this journal. We also respond to several concerns raised by Maggin, Briesch, and Chafouleas…

"Better Evidence, Better Choices, Better Schools," a recent report from the Center for American Progress and the Knowledge Alliance, focuses on the evidence-based research provisions in the Every Student Succeeds Act (ESSA). ESSA provisions ask districts and schools to consider various sources of evidence, make judgments about the…

One purpose of education research is to develop and rigorously evaluate the effectiveness of programs for supporting students' learning and achievement. The Institute of Education Sciences has amplified that purpose (Shadish & Cook, 2009) and attempted to improve the methodological standards for conducting such work--primarily through the What…

For transfer students, the transfer of credit between institutions creates a barrier to graduation as students' time and money is ultimately wasted when courses do not successfully transfer as credit applicable toward degree requirements at the receiving institution. Understanding the extent to which courses at your institution transfer to other…

In this article, we perform cost-effectiveness analysis on interventions that improve the rate of high school completion. Using the What Works Clearinghouse to select effective interventions, we calculate cost-effectiveness ratios for five youth interventions. We document wide variation in cost-effectiveness ratios between programs and between…

The Council of Australian Governments (COAG) has made a range of commitments to improve the lives of Indigenous Australians and in particular provide for a better future for Indigenous children. These commitments have re-focused the efforts of everyone working for a better future for Australia's Indigenous people. The Closing the Gap Clearinghouse…

The What Works Clearinghouse (WWC) seeks to provide educators, policymakers, researchers, and the public with a central and trusted source of scientific evidence for what works in education. The WWC was established in 2002 by the U.S. Department of Education's Institute of Education Sciences (IES). It serves as a decision-making resource by…

Regression discontinuity (RD) designs are increasingly used by researchers to obtain unbiased estimates of the effects of education-related interventions. These designs are applicable when a continuous "scoring" rule is used to assign the intervention to study units (for example, school districts, schools, or students). Under an RD…

A large body of literature documents the central importance of fidelity of program implementation in creating an internally valid research design and considering such fidelity in judgments of research quality. The What Works Clearinghouse (WWC) provides web-based summary ratings of educational innovations and is the only rating group that is…

The What Works Clearinghouse (WWC) provides online reports to the public about the scientific evidence for educational interventions. The quality of these reports is important because they effectively tell the non-scientific community which programmes do and do not work. The aim of this brief review is to assess WWC's report on a clinically…

The Closing the Gap Clearinghouse was established by the Council of Australian Governments (COAG) to bring together evidence-based research on overcoming disadvantage for Indigenous Australians. The Clearinghouse provides access to a collection of information on what works to improve Indigenous people's lives across the building blocks identified…
