To assist policymakers at all levels of government in identifying programs and making evidence-based and data-driven decisions, the Pew Results First Initiative created the Results First Clearinghouse Database. This one-stop online resource provides policymakers with an easy way to find information on the effectiveness of various interventions as rated by nine national research clearinghouses. While the database is not intended, to serve as a comprehensive list of all interventions that are worthy of funding, it is provided to assist policymakers as they consider the multitude of factors that inform budget and policy choices.     

The database contains information from nine national clearinghouses that conduct systematic research reviews to identify what works. While each uses slightly different procedures and criteria in its work, all use the same overall approach: They review and summarize research studies that assess the effectiveness of interventions.  The clearinghouses included in the database are:

• Blueprints for Healthy Youth Development
• California Evidence-Based Clearinghouse for Child Welfare
• The Laura and John Arnold Foundation’s Social Programs That Work
• The U.S. Department of Education’s What Works Clearinghouse
• The U.S. Department of Health and Human Services’ Research-Tested Intervention Programs
• The U.S. Department of Health and Human Services’ Teen Pregnancy Prevention Evidence Review
• U.S. Department of Justice’s CrimeSolutions.gov
• The U.S. Substance Abuse and Mental Health Services Administration’s National Registry of Evidence-based Programs and Practices
• The University of Wisconsin Population Health Institute and Robert Wood Johnson Foundation’s County Health Rankings and Roadmaps What Works for Health

*The National Registry of Evidence-based Programs and Practices (NREPP) stopped updating in January 2018 and is no longer accessible as of August 2018.  Although the Results First Clearinghouse Database still contains NREPP’s program reviews, links to its website will direct you to a third-party archived version of the NREPP website, where available.
