Clearinghouses and Evidence-Based Resources

August 1, 2020

This document provides a list of clearinghouses and evidence-based resources, which have been compiled by topic. Clearinghouses are registries of programs and interventions that have been reviewed and rated according to criteria set by each clearinghouse. Ratings typically reflect whether, and to what extent, the impact of the programs or interventions is supported by evidence. Clearinghouses can be helpful for:

  • Seeing the level of evidence behind a program or intervention;

  • Determining if a program or intervention is supported for a specific population or outcome; or

  • Identifying what the elements of successful programs or interventions are.

Clearinghouses should make the process of finding information about evidence-based programs and interventions easier, but there are considerations to note when using them such as the population:

  • Population alignment – A studied intervention may not necessarily be relevant to the population of interest.

  • Scale – was the study done locally or is it nationally representative?

  • Outcomes of interest – a program or intervention may only be effective for the outcomes specified and could have unintended consequences on other outcomes not measured (e.g. disproportionate impact)
