The Results First Clearinghouse Database is an online resource that brings together information on the effectiveness of social policy programs from nine national clearinghouses. It applies color-coding to the clearinghouses’ distinct rating systems, creating a common language that enables users to quickly see where each program falls on a spectrum from negative impact to positive impact. As such, this database can help users easily access and understand the evidence base for a variety of programs.

The database currently includes information on 3,155 programs and was last updated on November 19, 2021.

Please note that 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.
