For the "types of solutions", the Evidence Bank uses three international platforms that are regarded as international benchmarks for the production, analysis, and compilation of systematic reviews and meta-analyses relevant to the area of security and justice: Crime Solutions, from the Department of Justice (USA); Crime Reduction Toolkit, from the College of Policing (UK); and the Campbell Collaboration, a non-profit organization based in Norway. In addition to these platforms, the Evidence Bank also includes types of solutions that have been identified in the IDB Inventory, an in-house initiative for mapping and analyzing systematic reviews and impact evaluation scientific papers that was coordinated by the IDB's Citizen Security & Justice Division.
For the "evaluated cases", the main sources were, in addition to Crime Solutions and the IDB Inventory, the Blueprints for Healthy Youth Development, organized by the Center for the Study and Prevention of Violence, at the University of Colorado at Boulder, USA; the Evidence-Based Policing Matrix, organized by the Center for Evidence-Based Crime Policy (CEBCP), at George Mason University, USA; the Social Programs that Work (SPTW), a website run by the evidence-based public policy team at Arnold Ventures, a philanthropic organization based in the USA; and the California Evidence-Based Clearinghouse (CEBC), a repository organized and maintained by the Department of Social Services of the Government of California (USA), in partnership with the Chadwick Center for Children and Families.
