In 2019, WSIPP updated the full portfolio of juvenile justice meta-analyses, benefit-cost analyses, and the resulting evidence classifications. This work aligned with WSIPP’s ninth update of the Children’s Services Inventory (“the inventory”), published in December 2019. The inventory describes the research evidence and benefit-cost findings for a variety of programs in the areas of juvenile justice, child welfare, and children’s mental health, and classifies each program according to its level of evidence and benefit-cost findings.

WSIPP’s update to the inventory led to changes in the evidence classification for several juvenile justice programs operating in Washington State. Four programs previously classified as either evidence-based or research-based are now promising or null. This resource guide serves as a companion document to the inventory and as a resource for Washington State policymakers and practitioners to understand how changes in the meta-analyses and benefit-cost analyses of juvenile justice programs resulted in changes to evidence classifications.

In the guide, WSIPP explains the specific changes made to all meta-analyses and benefit-cost analyses of juvenile justice programs in 2019. Then, the guide provides details for several programs eligible for Washington State funding for youth involved in the juvenile courts or committed to a Juvenile Rehabilitation facility. For each eligible program, the guide reviews relevant changes to the content in the specific meta-analysis, changes to the calculations of meta-analytic results, changes made to the costs of the program, and changes made to WSIPP’s standard benefit-cost model. While WSIPP classifies a broad array of programs, and these evidence classifications are subject to change over time, this guide focuses specifically on changes to classifications for juvenile justice programs eligible for state dollars.

The 2013 Washington State Legislature passed a bill to facilitate the use of evidence-based programs in adult corrections. The legislature directed WSIPP to define the terms “evidence-based” and “research-based” and create an inventory of adult corrections programs classified as evidence-based or research-based.

WSIPP produced the first inventory of evidence-based and research-based programs for adult corrections in 2013. This is an update to the original inventory, classifying an additional 30 programs, for a total of 57 programs.

The 2009 Washington Legislature directed the Institute to “calculate the return on investment to taxpayers from evidence-based prevention and intervention programs and policies.” The Legislature instructed the Institute to produce “a comprehensive list of programs and policies that improve . . . outcomes for children and adults in Washington and result in more cost-efficient use of public resources.” This report summarizes our findings as of April 2012. Readers can download the technical appendix for details about our methods.

Washington State provides funding to school districts to help underachieving students through the Learning Assistance Program (LAP). The 2013 Washington State Legislature directed the Washington State Institute for Public Policy to prepare an inventory of evidence-based and research-based effective practices, activities, and programs for use by school districts in LAP and to update the inventory each two years thereafter.

This report describes the second update to the inventory of evidence-based and research-based practices for use in LAP.
