Intimate Partner Violence in Idaho, 2020
December 2021

This research brief examines recent trends regarding intimate partner violence in Idaho. Data includes victims known to law enforcement, victims who received grant-funded services, and feedback from victim service agencies. Since 2016, the rate of victims known to law enforcement per capita has decreased, but the number of victims accessing grant-funded services has increased. Notable agency needs include resources to train and retain staff, expand service availability, respond to evolving effects of the COVID-19 pandemic, and provide safe shelter or housing to victims of intimate partner violence.

Crossover Youth in Eastern Idaho: Results from the District 6 Crossover Youth Practice Model Pilot Project
October 2021

In 2019, a group of juvenile justice and child welfare stakeholders launched the Crossover Youth Practice Model (CYPM) as a pilot project in Bannock, Oneida, and Power Counties. Fully implemented in February 2020, the CYPM aims to streamline services for “crossover youth”, youth who are involved in both the juvenile justice and child welfare systems, by bringing together stakeholders from both systems to create joint case management plans that provide the most appropriate services to crossover youth in a more efficient manner. For this report, ISAC analyzed data collected during the first year of CYPM implementation that measure both program implementation progress and outcomes for crossover youth. Results and recommendations for next steps are presented here.


Recidivism Rates Among the Idaho Department of Correction’s Supervised Population
October 2021

ISAC used data from the Idaho Department of Correction (IDOC) and the Idaho Supreme Court (ISC) to determine 3-year recidivism rates among felony offenders in Idaho, utilizing five definitions of recidivism. ISAC conducted survival analyses for each definition. This report presents the results of those analyses, compares the results to other measures of recidivism being used by Idaho justice system actors, and makes recommendations to stakeholders for conducting recidivism research that allows for flexibility and responsiveness to the context in which such work is conducted.
