In 1998, Washington State voters legalized the use of medical marijuana for certain medical purposes. Very little is known about patient access to medical marijuana and other implications of the law. At the local level, some cities and counties have prohibited collective cultivation of medicinal marijuana. Most Washington residents, however, live in areas that allow collective gardens.

This report describes local regulations regarding medical marijuana.

In 2021, the Washington State Health Care Authority (HCA) conducted a survey of adults in Washington to better understand the prevalence of gambling and problem gambling. HCA contracted with WSIPP to conduct additional analyses.

WSIPP’s analysis found that fewer than half of respondents reported they had gambled in the past 12 months. Of those who had gambled, 3.5% were classified as problem gamblers. Statistically significant differences were detected in the prevalence of gambling and problem gambling among some different demographic populations (demographics collected include gender, marital status, ethnicity, age, education, military service, employment, type of insurance, and geographic region). Compared to those who gambled only in brick-and-mortar establishments, online gamblers were significantly more likely to be problem gamblers. Gamblers who self-identified as having problems with substance use, mental health, or other behaviors, were more likely to be problem gamblers than others not reporting these problems. Most of the population said they thought the harms of gambling outweighed the benefits. A similar proportion said the availability in Washington was fine—neither too available nor not available enough.

The Learning Assistance Program (LAP) provides supplemental services to K–12 students who are not meeting standards in reading, writing, mathematics, or readiness in these areas. In 2014, the Washington Legislature directed WSIPP to develop an inventory of programs that could be used in LAP, classify programs as evidence-based, research-based, or promising, and update this inventory every two years. WSIPP’s current LAP inventory includes 58 programs related to topics like tutoring, educator professional development, family engagement, community-based partnerships, and behavioral supports.

WSIPP was scheduled to update the inventory in 2022 but has put a hold on this work while it assesses the use of the inventory. In the absence of our regular update, this brief provides a historical review of the LAP inventory, describes potential changes resulting from 2021 legislation, and offers a discussion of options regarding the future of the inventory.

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.” The Legislature authorized the Institute to receive outside funding for this project; the MacArthur Foundation supported 80 percent of the work and the Legislature funded the other 20 percent. This main report summarizes our findings. Readers can download the two detailed technical appendices for in depth results and statistical 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 initial inventory of evidence-based and research-based practices for use in LAP.

The 2016 Washington State Legislature created the Statewide Reentry Council with the goals of reducing recidivism and improving other outcomes for people who return to the community after incarceration. This legislation also directed WSIPP to examine the effectiveness of reentry programs through a systematic review of the research literature.

Using WSIPP’s standardized procedures, we examined 59 programs to estimate their average effectiveness in reducing recidivism and improving other outcomes. In this report, we describe our meta-analytic and benefit-cost findings for these programs.

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 fourth update to the inventory of evidence-based and research-based practices for use in LAP.

EBPI & WSIPP - December 2019

The 2012 Legislature passed E2SHB 2536 with the intention that “prevention and intervention services delivered to children and juveniles in the areas of mental health, child welfare, and juvenile justice be primarily evidence-based and research-based, and it is anticipated that such services will be provided in a manner that is culturally competent.”

The bill directed the Washington State Institute for Public Policy (WSIPP) and the University of Washington Evidence-Based Practice Institute (UW) to publish descriptive definitions and prepare an inventory of evidence-based, research-based, and promising practices and services, and to periodically update the inventory as more practices are identified. This is the ninth update to the initial inventory published in 2012.

The accompanying report describes our standard process for evaluating and classifying research evidence, the process for adding new programs to the inventory, and the reasons that program classifications may change. Programs that are new to the inventory or have a revised classification based on current evidence are identified in the report.

Washington State provides funding to school districts to help students who score below grade-level standards in English Language Arts (ELA) and mathematics through the Learning Assistance Program (LAP). Districts can use the funding for a variety of activities to support students including tutoring, extended learning time, educator professional development, and family engagement to name a few examples.

The 2013 Washington State Legislature directed the Washington State Institute for Public Policy (WSIPP) to develop an inventory of evidence-based, research-based, and promising programs and practices for use by school districts in LAP. WSIPP was directed to update the inventory every two years thereafter. This report is the fifth update to the inventory and describes our standard process for evaluating and classifying programs, adding new programs to the inventory, and reasons why program classifications may change over time. We also identify several programs that are relevant to teaching and learning in a remote environment during the novel coronavirus (COVID-19), although that was not the focus of this update. Overall, for this 2020 update, we reviewed 18 programs, added two new programs to the inventory, and reclassified five programs included in previous inventory iterations.

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.
