Training and Technical Assistance Repository
This repository of government documents brings together years of expert research on training and technical assistance (TTA) developed by the US Department of Justice in partnership with CNA. Since many of them are no longer accessible to the public on government websites, CNA is making these government documents available for the benefit of the criminal justice field.
These documents were products of six TTA programs managed by CNA’s Center for Justice Research and Innovation:
- Body-Worn Camera Policy and Implementation Program (BWCPIP)
- Collaborative Reform Initiative Organizational Assessment (CRI OA)
- Community Based Violence Intervention and Prevention Initiative (CVIPI)
- Jails and Justice Support Center (JJSC)
- National Public Safety Partnership (PSP)
- Project Safe Neighborhoods (PSN)
