Evidence-Based Program Directories

Multiple federal agencies have put together registries that list evidence-based programs as a way to disseminate information about programs and their level of effectiveness. Registries list programs and categorize them, similar to a consumer guide. This process allows users to identify programs that best meet their needs and have a body of research behind them. Registries vary in the programs they include, how they define evidence, the depth of evidence they require, the criteria they use for classifying evidence-based programs, and their area of focus. View the range of directories and resources available by Department and Agency below.

CLEAR: Clearinghouse for Labor Evaluation and Research
CLEAR's mission is to make research on labor topics more accessible to practitioners, policymakers, researchers, and the public more broadly so that it can inform their decisions about labor policies and programs. CLEAR identifies and summarizes many types of research, including descriptive statistical studies and outcome analyses, implementation, and causal impact studies. For causal impact studies, CLEAR assesses the strength of the design and methodology in studies that look at the effectiveness of particular policies and programs.
