The What Works Clearinghouse (WWC) serves as a central and trusted source of scientific evidence for what works in education. The WWC designs its resources to help educators, administrators, families, researchers, and policymakers make evidence-based decisions. In fall 2023, the WWC convened the Small Working Group of Experienced Education…

Clearinghouses set standards of scientific quality to vet existing research to determine how "evidence-based" an intervention is. This paper examines 12 educational clearinghouses to describe their effectiveness criteria, to estimate how consistently[underlined] they rate the same program, and to probe why their judgments differ. All the…

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…

Drawing on our five years of experience developing WWC evidence standards and reviewing studies against those standards as well as current literature on the design of impact studies, we highlight in this paper some of the most critical issues and common pitfalls in designing and conducting impact studies in education, and provide practical…

KIPP (Knowledge is Power Program) is a national network of public charter schools whose stated mission is to help underserved students enroll in and graduate from college. Prior studies (see Tuttle et al. 2013) have consistently found that attending a KIPP middle school positively affects student achievement, but few have addressed longer-term…

Based on investigation and analysis of the What Works Clearinghouse (WWC) review process and reports, this panel concluded that: (1) WWC procedures and processes for identifying and extracting information from intervention studies are generally well documented and follow reasonable standards and practices for systematic reviews; and (2) WWC…

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…

This chapter describes the National Student Clearinghouse and discusses opportunities and challenges for tracking community college students. It also presents a system perspective on using clearinghouse data to promote more comprehensive student and graduate tracking. (Contains 2 tables.)

Much of the discussion in the news, schools and statehouses about the NO Child Left Behind Act has focused on testing and accountability, and whether there is enough money to fund the act sufficiently. However, bubbling underneath this publicity is a term that has the potential to cause a minor ripple on the surface or to erupt like ah underwater…

After nearly two years in development, a new federally backed research service on "what works" in education began rolling its first products off the assembly line. Launched with $18.5 million in funding from the U.S. Department of Education, the newly operational What Works Clearinghouse is the department's electronic version of a "Consumer…

The Knowledge Network of Washington (KNOW-NET) Dissemination Project in Washington State from 1980 to 1985 is described prior to and following funding by the National Institute of Education. As a state capacity building project, KNOW-NET had five major components: (1) coordination/leadership; (2) building information resources; (3) building…

This article summarizes the findings of the National Research Council (NRC) report "On Evaluating Curricular Effectiveness" and examines the reviews in middle grades mathematics undertaken by the What Works Clearinghouse (WWC). The NRC report reviewed and assessed 147 key evaluations of 13 National Science Foundation-supported K-12 mathematics…
